+
+# GitHub Agentic Workflows Agent
+
+This agent helps you work with **GitHub Agentic Workflows (gh-aw)**, a CLI extension for creating AI-powered workflows in natural language using markdown files.
+
+## What This Agent Does
+
+This is a **dispatcher agent** that routes your request to the appropriate specialized prompt based on your task:
+
+- **Creating new workflows**: Routes to `create` prompt
+- **Updating existing workflows**: Routes to `update` prompt
+- **Debugging workflows**: Routes to `debug` prompt
+- **Upgrading workflows**: Routes to `upgrade-agentic-workflows` prompt
+- **Creating report-generating workflows**: Routes to `report` prompt — consult this whenever the workflow posts status updates, audits, analyses, or any structured output as issues, discussions, or comments
+- **Creating shared components**: Routes to `create-shared-agentic-workflow` prompt
+- **Fixing Dependabot PRs**: Routes to `dependabot` prompt — use this when Dependabot opens PRs that modify generated manifest files (`.github/workflows/package.json`, `.github/workflows/requirements.txt`, `.github/workflows/go.mod`). Never merge those PRs directly; instead update the source `.md` files and rerun `gh aw compile --dependabot` to bundle all fixes
+- **Analyzing test coverage**: Routes to `test-coverage` prompt — consult this whenever the workflow reads, analyzes, or reports on test coverage data from PRs or CI runs
+- **Rendering ASCII charts in markdown**: Routes to `asciicharts` guide — consult this whenever the workflow needs compact charts that render reliably in GitHub issues, comments, or discussions
+- **CLI commands and triggering workflows**: Routes to `cli-commands` guide — consult this whenever the user asks how to run, compile, debug, or manage workflows from the command line, or when they need the MCP tool equivalent of a `gh aw` command
+- **Reducing token consumption / cost optimization**: Routes to `token-optimization` guide — consult this whenever the user asks how to reduce token usage, lower costs, speed up workflows, or measure the impact of prompt changes with experiments
+- **Choosing workflow architectures and design patterns**: Routes to `patterns` guide — consult this whenever the user asks for strategy, architecture, operating models, or pattern selection for agentic workflows
+
+Workflows may optionally include:
+
+- **Project tracking / monitoring** (GitHub Projects updates, status reporting)
+- **Orchestration / coordination** (one workflow assigning agents or dispatching and coordinating other workflows)
+
+## Files This Applies To
+
+- Workflow files: `.github/workflows/*.md` and `.github/workflows/**/*.md`
+- Workflow lock files: `.github/workflows/*.lock.yml`
+- Shared components: `.github/workflows/shared/*.md`
+- Configuration: `https://raw.githubusercontent.com/github/gh-aw/main/.github/aw/github-agentic-workflows.md`
+
+## Problems This Solves
+
+- **Workflow Creation**: Design secure, validated agentic workflows with proper triggers, tools, and permissions
+- **Workflow Debugging**: Analyze logs, identify missing tools, investigate failures, and fix configuration issues
+- **Version Upgrades**: Migrate workflows to new gh-aw versions, apply codemods, fix breaking changes
+- **Component Design**: Create reusable shared workflow components that wrap MCP servers
+
+## How to Use
+
+When you interact with this agent, it will:
+
+1. **Understand your intent** - Determine what kind of task you're trying to accomplish
+2. **Route to the right prompt** - Load the specialized prompt file for your task

+
+1. **Identify the task type** from the user's request
+2. **Load the appropriate prompt** from the URLs listed above
+3. **Follow the loaded prompt's instructions** exactly
+4. **If uncertain**, ask clarifying questions to determine the right prompt
+
+## Quick Reference
+
+```bash
+# Initialize repository for agentic workflows
+gh aw init
+
+# Generate the lock file for a workflow
+gh aw compile [workflow-name]
+
+# Trigger a workflow on demand (preferred over gh workflow run)
+gh aw run <workflow-name>             # interactive input collection
+gh aw run <workflow-name> --ref main  # run on a specific branch
+
+# Debug workflow runs
+gh aw logs [workflow-name]
+gh aw audit <run-id>
+
+# Upgrade workflows
+gh aw fix --write
+gh aw compile --validate
+```
+
+## Key Features of gh-aw
+
+- **Natural Language Workflows**: Write workflows in markdown with YAML frontmatter
+- **AI Engine Support**: Copilot, Claude, Codex, or custom engines
+- **MCP Server Integration**: Connect to Model Context Protocol servers for tools
+- **Safe Outputs**: Structured communication between AI and GitHub API
+- **Strict Mode**: Security-first validation and sandboxing
+- **Shared Components**: Reusable workflow building blocks
+- **Repo Memory**: Persistent git-backed storage for agents
+- **Sandboxed Execution**: All workflows run in the Agent Workflow Firewall (AWF) sandbox, enabling full `bash` and `edit` tools by default
+
+## Important Notes
+
+- Always reference the instructions file at `https://raw.githubusercontent.com/github/gh-aw/main/.github/aw/github-agentic-workflows.md` for complete documentation
+- Use the MCP tool `agentic-workflows` when running in GitHub Copilot Cloud
+- Workflows must be compiled to `.lock.yml` files before running in GitHub Actions
+- **Bash tools are enabled by default** - Don't restrict bash commands unnecessarily since workflows are sandboxed by the AWF
+- Follow security best practices: minimal permissions, explicit network access, no template injection
+- **Network configuration**: Use ecosystem identifiers (`node`, `python`, `go`, etc.) or explicit FQDNs in `network.allowed`. Bare shorthands like `npm` or `pypi` are **not** valid. See `https://raw.githubusercontent.com/github/gh-aw/main/.github/aw/network.md` for the full list of valid ecosystem identifiers and domain patterns.
+- **Single-file output**: When creating a workflow, produce exactly **one** workflow `.md` file. Do not create separate documentation files (architecture docs, runbooks, usage guides, etc.). If documentation is needed, add a brief `## Usage` section inside the workflow file itself.
+- **Triggering runs**: Always use `gh aw run <workflow-name>` to trigger a workflow on demand — not `gh workflow run <file>.lock.yml`. `gh aw run` handles workflow resolution by short name, input parsing and validation, and correct run-tracking for agentic workflows. Use `--ref <branch>` to run on a specific branch.
+- **CLI commands reference**: For a complete guide on all `gh aw` commands and their MCP tool equivalents (for restricted environments), see `https://raw.githubusercontent.com/github/gh-aw/main/.github/aw/cli-commands.md`

+## Terminal Execution Safety
+- Treat any non-zero shell exit code as a failed step that requires correction before proceeding.
+- If a bash process exits, do not wait for more output from that process; rerun the command in a fresh terminal session.
+- Validate that expected command output was produced before using it as evidence for conclusions.
+- When terminal execution fails, surface the failure immediately and retry with a corrected command.
+- Avoid `set -e` in this automation workflow; use focused commands and verify each result explicitly so shell exits are observable and attributable.
+- Prefer short, single-purpose terminal commands over long chained scripts when debugging or gathering state.

+# Choosing Third-Party Package Dependency Versions
+
+Guidance for choosing versions of **external (third-party) NuGet package dependencies** in multi-targeted projects (e.g. `net462;net8.0;net9.0`).
+
+> **Scope:** This document covers dependencies consumed from NuGet — packages the SqlClient repo does NOT own. For versioning of SqlClient's own inter-sibling packages (Logging, Abstractions, SqlClient, Azure, AKV Provider, SqlServer.Server), see `sqlclient-package-versions.instructions.md`.
+
+## Rule
+For runtime-aligned packages, **the package major must match the target runtime major**: 8.x on `net8.0`, 9.x on `net9.0`, 10.x on `net10.0`, and so on. TFMs that aren't tied to a specific runtime major (`net462`, `netstandard2.0`) get the major of the floor LTS. Other categories are versioned as described below.
+
+Split package references into three categories:
+
+### 1. Runtime-aligned packages — **version per TFM, matching the runtime band**
+
+Packages whose major version ships with (or is tightly coupled to) a specific .NET runtime:
+
+- `Microsoft.Extensions.*` (Logging, DependencyInjection, Configuration, Hosting, Options, Caching, Http, Primitives, ...)
+- `Microsoft.AspNetCore.*`
+- `Microsoft.EntityFrameworkCore.*`
+- `System.Text.Json`, `System.Memory`, `System.IO.Pipelines`, `System.Formats.Asn1`, `System.Security.Cryptography.Pkcs`
+- `Microsoft.Bcl.*`
+
+Use the major version that matches the TFM. For TFMs without a corresponding runtime major (`net462`, `netstandard2.0`, etc.), use the major of the **lowest supported modern TFM** — typically the floor LTS (e.g. `8.x` while net8 is supported). This keeps the legacy targets on a long-lived, well-patched band and avoids dragging in transitive deps from a newer major:
+
+```xml
+<!-- Defaults: lowest supported runtime band (e.g. net8 LTS); also applies to net462 / netstandard2.0 -->
+<ItemGroup>
+  <PackageVersion Include="Microsoft.Extensions.Logging" Version="8.0.1" />
+  <PackageVersion Include="System.Text.Json"             Version="8.0.5" />
+</ItemGroup>
+
+<ItemGroup Condition="'$(TargetFramework)' == 'net9.0'">
+  <PackageVersion Update="Microsoft.Extensions.Logging" Version="9.0.0" />
+  <PackageVersion Update="System.Text.Json"             Version="9.0.0" />
+</ItemGroup>
+```
+
+When the floor LTS drops out of support, bump the default block to the new floor LTS major and drop any conditional block that becomes redundant.
+
+### 2. Independent packages — **single version across all TFMs**
+
+Packages whose versioning is decoupled from the .NET runtime:
+
+- `Newtonsoft.Json`, `Polly.*`, `Serilog.*`
+- `Azure.*`, `Microsoft.Identity.*`, `Microsoft.IdentityModel.*`
+- `Microsoft.Data.SqlClient`, `Dapper`, `StackExchange.Redis`
+- Most third-party packages
+
+Reference one (latest stable) version unconditionally:
+
+```xml
+<PackageVersion Include="Newtonsoft.Json" Version="13.0.4" />
+<PackageVersion Include="Azure.Identity"  Version="1.17.1" />
+```
+
+### 3. Polyfills — **conditional presence, single version**
+
+Packages that only exist (or are only needed) on older TFMs. The polyfill major doesn't have to match any runtime band (older TFMs have no in-box equivalent), so pick the latest stable available:
+
+```xml
+<ItemGroup Condition="'$(TargetFramework)' == 'netstandard2.0' OR '$(TargetFramework)' == 'net462'">
+  <PackageReference Include="Microsoft.Bcl.AsyncInterfaces" Version="10.0.0" />
+</ItemGroup>
+```
+
+Condition the *presence* of the reference, not the version.
+
+## How to categorize a package
+
+The named lists above aren't exhaustive. To classify a package you don't recognize, work through these steps in order:
+
+### 1. Read the nuget.org description
+
+Pure polyfills almost always say so explicitly. For example, `Microsoft.Bcl.TimeProvider`'s page reads: *"For apps targeting .NET 8 and newer versions, referencing this package is unnecessary, as the types it contains are already included in the .NET 8 and higher platform versions."*
+
+If the description says "for apps targeting .NET X and earlier" or "unnecessary on .NET X+", treat as polyfill candidate and continue to step 2 to confirm. If it makes no such claim and the package owner is Microsoft + a major number tracks the .NET release train, treat as runtime-aligned candidate.
+
+### 2. Inspect the package's `lib/` layout
+
+Look at the "Frameworks" tab on nuget.org or open the `.nupkg`:
+
+| `lib/` layout | Category |
+|---|---|
+| Only older TFM folders (`netstandard2.0`, `net462`) — no modern TFMs | Pure polyfill |
+| `lib/net8.0/_._`, `lib/net9.0/_._` placeholders + real DLL only on older TFMs | Pure polyfill (no-op on modern TFMs) |
+| Real DLLs in `lib/net8.0/`, `lib/net9.0/`, `lib/net10.0/`, differing per band | Runtime-aligned |
+| Real DLLs on every TFM including older ones, single major doesn't track .NET releases | Independent |
+
+### 3. Check the release cadence
+
+- Runtime-aligned: new major every November in lockstep with .NET (8.0, 9.0, 10.0, ...) plus monthly servicing patches.
+- Independent: releases on its own schedule, major doesn't correlate with .NET versions.
+- Pure polyfill: usually freezes at one major and rarely bumps; new majors only to ride the build train.
+
+### 4. Functional test — remove the reference and rebuild
+
+The decisive test for the polyfill-vs-runtime-aligned boundary: remove the `PackageReference` on a modern TFM (e.g. net8) and build.
+
+- Builds clean → package was acting as a polyfill on that TFM. Confirm category 3.
+- Fails with `CS0246`/`CS1061` (missing type or method) → the package contributes API the in-box BCL doesn't have. Treat as runtime-aligned (category 1), even if the description sounds polyfill-ish.
+
+### Beware hybrids
+
+Some packages look like polyfills but add API beyond the in-box BCL even on modern TFMs. Treat these like runtime-aligned packages.
+
+### When in doubt
+
+Treat as **runtime-aligned** (category 1) and reference on every TFM with per-TFM majors.
+
+- Cost of mis-classifying a true polyfill this way: a redundant `_._` asset at restore. Harmless.
+- Cost of mis-classifying a hybrid as a pure polyfill: a compile break on the TFMs where you dropped the reference.
+
+## Why
+
+### Why latest minor/patch always
+
+`PackageReference` versions are minimums (`[X, ∞)`), so writing a stale minor or patch buys nothing for downgrade-safety and only loses fixes:
+
+- **Security**: BCL and Extensions packages ship CVE patches in minor/patch bumps. Pinning to an older patch means a customer who doesn't transitively pull a newer version stays on the vulnerable floor.
+- **Bug fixes**: Same logic for non-security fixes. We have no reason to anchor customers to an older `8.0.0` when `8.0.5` is available.
+- **NU1605 risk is small and easy to fix**: NU1605 fires on *any* downgrade, including minor/patch within the same major (e.g. our `8.0.5` transitive vs. a customer's direct `8.0.0`). In practice this is rare and trivial to resolve — the customer bumps their direct reference to a current patch. The cost of *not* tracking latest (stale security/bug fixes for every consumer who doesn't override) is larger than the cost of an occasional one-line bump in a consumer project.
+- **Reduces noise from automated bumps**: Dependabot/Renovate PRs disappear if we already track latest.
+
+This rule applies to all three categories. The category decides the major; "latest" decides the minor and patch.
+
+### NuGet `PackageReference` versions are minimums, not pins
+
+`Version="X"` means `[X, ∞)`. The resolver picks the highest version requested across the graph, with one critical exception: a **direct** reference wins over a transitive one (nearest-wins).
+
+### NU1605 fires when the customer's direct version is *lower* than your transitive version
+
+If your library transitively requires `Microsoft.Extensions.Logging 10.0.0` and the consuming app has a direct `<PackageReference Version="8.0.0" />`, NuGet detects a downgrade and emits **NU1605**. In modern SDKs this is an **error**, not a warning — the customer's build fails.
+
+The reverse (customer's direct version higher than your transitive) resolves cleanly with no warning.
+
+### The asymmetry drives the rule
+
+| Your transitive version | Customer's direct version | Result |
+|---|---|---|
+| 10.x | 8.x | **NU1605 error** |
+| 10.x | 10.x or higher | Clean |
+| 8.x  | 8.x or higher | Clean |
+
+Pinning runtime-aligned packages to the **band matching each TFM** means a net8 consumer transitively gets 8.x (no friction with their own 8.x reference), and a net10 consumer transitively gets 10.x.
+
+Pinning everything to the latest major (e.g. `10.x` unconditionally) forces every net8 customer to roll their direct references forward or hit NU1605.
+
+### Independent packages don't have this problem
+
+`Newtonsoft.Json 13.x`, `Azure.Identity 1.17.x`, etc. aren't tied to a runtime version. Customers don't have a "matching" version in mind, and the package's own multi-targeted assets handle TFM selection internally. One version is simpler and avoids needless conditional blocks.
+
+### Framework-provided assemblies win at runtime anyway
+
+On .NET 8+, packages like `System.Text.Json` and `System.Memory` are part of the shared framework. Even if you reference `System.Text.Json 9.0.0`, a net8 app uses the in-box net8 copy at runtime. Referencing 10.x on net8 just creates restore-graph noise with no runtime benefit — another reason to match the band.
+
+## Tradeoffs and alternatives considered
+
+### Per-TFM (the rule) vs. single lowest-LTS version
+
+A "pin everything to the lowest supported LTS major (e.g. 8.x everywhere) and bump only when that LTS drops" policy is also downgrade-safe and simpler in `Directory.Packages.props`. We rejected it because:
+
+- Customers on newer runtimes lose access to perf/feature work that landed in later package majors for packages that *aren't* fully overridden by the in-box shared framework (e.g. `Microsoft.Extensions.Caching.Memory`, `System.Configuration.ConfigurationManager`).
+- The simplification is small: one extra conditional `ItemGroup` per runtime-aligned package.
+- A coordinated bump when the floor LTS drops is a larger, riskier change than incremental per-TFM updates.
+
+Per-TFM keeps each runtime on its matching band and confines change to one `Update` line at a time.
+
+### Why no upper bounds
+
+Customers can transitively pull in a *higher* major than your reference. NuGet resolves nearest-wins with no warning, so a major that broke API can produce `MissingMethodException`/`TypeLoadException` at runtime rather than a restore-time failure.
+
+An upper bound (e.g. `Version="[8.0.0, 10.0.0)"`) would convert that runtime failure into a restore-time `NU1107` and is the only way to guarantee compatibility. We still avoid it because:
+
+- It blocks customers from rolling forward to fix CVEs or take perf wins in the newer major.
+- It propagates conflicts deep into customer dependency graphs that we can't see.
+- Microsoft's [library guidance](https://learn.microsoft.com/dotnet/standard/library-guidance/dependencies#nuget-dependency-version-ranges) explicitly says **AVOID upper bounds**, and the foundational Microsoft libraries (EF Core, ASP.NET Core, Aspire, Orleans, the BCL itself, Azure SDK) follow it.
+- Exact pins (`[X]`) in Microsoft repos are reserved for host-coupled scenarios: Roslyn analyzers (`Microsoft.CodeAnalysis.*`), MSBuild API consumers (`Microsoft.Build`), VS extensibility. None apply to runtime libraries like SqlClient.
+
+We accept the SemVer-break risk in exchange for not breaking customer rollforward. If a specific package is known to break compatibility at a future major, document it in code review and revisit — don't blanket-bound.
+
+### Downgrade direction matters
+
+| Your transitive | Customer's direct | Result |
+|---|---|---|
+| Higher | Lower | **NU1605 error** (we cause this) |
+| Lower | Higher | Clean restore, customer's wins |
+| Equal | Equal | Clean |
+
+The asymmetry is the entire reason per-TFM matching works: it makes us the *lower* or *equal* for any customer who has aligned their own references with their runtime.
+
+## Checklist before changing a package version
+
+1. Is the package in the runtime-aligned list above? → use per-TFM conditional `PackageVersion Update`, latest minor/patch in each band.
+2. Is it independent? → single `PackageVersion`, latest stable.
+3. Is it a polyfill? → conditional `PackageReference` only on TFMs that need it, latest stable.
+4. Always pick the latest available minor/patch within the chosen major. Don't carry forward a stale minor when bumping or adding.
+5. Prefer Central Package Management (`Directory.Packages.props`) over per-project versions.
+6. Never use exact-version (`[X]`) or upper-bound (`[X, Y)`) ranges on `PackageReference` unless you have a documented compatibility reason.

-## Main Pipelines
-
-### CI Core Pipeline (`dotnet-sqlclient-ci-core.yml`)
-Reusable core CI pipeline consumed by both project-reference and package-reference CI pipelines. Configurable parameters:
-
-| Parameter | Description | Default |
-|-----------|-------------|---------|
-| `targetFrameworks` | Windows test frameworks | `[net462, net8.0, net9.0, net10.0]` |
-| `targetFrameworksUnix` | Unix test frameworks | `[net8.0, net9.0, net10.0]` |

-| `testJobTimeout` | Test job timeout (minutes) | Required |
-| `runAlwaysEncryptedTests` | Include AE tests | `true` |
-| `enableStressTests` | Include stress test stage | `false` |
-
-### CI Reference Pipelines
-- `dotnet-sqlclient-ci-project-reference-pipeline.yml` — Full CI using project references (builds from source)
-- `dotnet-sqlclient-ci-package-reference-pipeline.yml` — Full CI using package references (tests against published NuGet packages)
-
-### PR Validation Pipelines
-- `sqlclient-pr-project-ref-pipeline.yml` — PR validation with project references
-- `sqlclient-pr-package-ref-pipeline.yml` — PR validation with package references
-
-These pipelines trigger on pull requests and run a subset of the full CI matrix to provide fast feedback.
-
-### Official/Signing Pipeline (`dotnet-sqlclient-signing-pipeline.yml`)
-Signs and publishes NuGet packages. Used for official releases. Requires secure service connections and key vault access for code signing.
-
-### AKV Official Pipeline (`akv-official-pipeline.yml`)
-Builds and signs the `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider` add-on package separately from the main driver. Uses 1ES pipeline templates for compliance.
-
-### Stress Tests Pipeline (`stress-tests-pipeline.yml`)
-Optional pipeline for long-running stress and endurance testing. Enabled via `enableStressTests` parameter in CI core.
-
-## Build Stages
-
-1. **build_abstractions_package_stage**: Build and pack abstractions
-2. **build_sqlclient_package_stage**: Build main driver and AKV packages
-3. **build_azure_package_stage**: Build Azure extensions package
-4. **stress_tests_stage**: Optional stress testing
-5. **run_tests_stage**: Execute all test suites
+# Azure DevOps CI/CD Pipeline Guidelines
+
+## Purpose
+
+Rules and conventions for editing the Azure DevOps CI/CD pipelines that build, test, and validate Microsoft.Data.SqlClient. These pipelines live under `eng/pipelines/` (excluding `onebranch/`, which is covered by separate instructions).
+
+**ADO Organization**: sqlclientdrivers | **ADO Project**: ADO.NET
+
+## Pipeline Layout
+
+Two categories of pipelines exist in this repository:
+
+- **CI/PR pipelines** (`eng/pipelines/`) — Build, test, and validate on every push/PR
+- **OneBranch pipelines** (`eng/pipelines/onebranch/`) — Official signing/release builds (separate instructions file)
+
+Top-level CI/PR pipeline files:
+- `dotnet-sqlclient-ci-core.yml` — Reusable core template; all CI and PR pipelines extend this
+- `dotnet-sqlclient-ci-package-reference-pipeline.yml` — CI with Package references (Release)
+- `dotnet-sqlclient-ci-project-reference-pipeline.yml` — CI with Project references (Release)
+- `sqlclient-pr-package-ref-pipeline.yml` — PR validation with Package references
+- `sqlclient-pr-project-ref-pipeline.yml` — PR validation with Project references
+- `ci/stress/sqlclient-ci-stress-pipeline.yml` — Stress test pipeline and templates
+
+Reusable templates are organized under:
+- `common/templates/jobs/` — Job templates (`ci-build-nugets-job`, `ci-code-coverage-job`, `ci-run-tests-job`)
+- `common/templates/stages/` — Stage templates (`ci-run-tests-stage`)
+- `common/templates/steps/` — Step templates (build, test, config, publish)
+- `jobs/` — Package-specific CI jobs (pack/test Abstractions, Azure, Logging, stress)
+- `stages/` — Package-specific CI stages (generate secrets, build SqlServer/Logging/Abstractions/SqlClient/Azure, verify packages)
+- `libraries/` — Shared variables (`ci-build-variables.yml`)
+- `steps/` — SDK install steps
+
+## CI Core Template
+
+`dotnet-sqlclient-ci-core.yml` is the central orchestrator. All CI and PR pipelines extend it with different parameters.
+
+Key parameters:
+- `referenceType` (required) — `Package` or `Project`; controls how sibling packages are referenced
+- `buildConfiguration` (required) — `Debug` or `Release`
+- `testJobTimeout` (required) — test job timeout in minutes
+- `targetFrameworks` — Windows test TFMs; default `[net462, net8.0, net9.0, net10.0]`
+- `targetFrameworksUnix` — Unix test TFMs; default `[net8.0, net9.0, net10.0]`
+- `netcoreVersionTestUtils` — default runtime for shared test utilities; default `net10.0`
+- `testSets` — test partitions; default `[1, 2, 3]`
+- `useManagedSNI` — SNI variants to test; default `[false, true]`
+- `runAlwaysEncryptedTests` — include AE test set; default `true`
+- `runLegacySqlTests` — include SQL Server 2016/2017 manual-test legs; default `true`
+- `debug` — enable debug output; default `false`
+- `dotnetVerbosity` — build verbosity; default `normal`
+
+## Build Stage Order
+
+Stages execute in dependency order (Package reference mode requires artifacts from prior stages):
+1. `generate_secrets` — Generate test secrets
+2. `build_sqlserver_package_stage` — Build `Microsoft.SqlServer.Server`
+3. `build_logging_package_stage` — Build Logging package
+4. `build_abstractions_package_stage` — Build Abstractions (package mode depends on Logging)
+5. `build_sqlclient_package_stage` — Build SqlClient and produce the AKV provider package
+6. `build_azure_package_stage` — Build Azure extensions
+7. `verify_nuget_packages_stage` — Verify NuGet package metadata
+8. `ci_run_tests_stage` — Run MDS and AKV test suites
+
+Stress testing is no longer a stage threaded through `dotnet-sqlclient-ci-core.yml`; it lives under `eng/pipelines/ci/stress/` as a separate pipeline flow.
+
+When adding a new build stage, respect the dependency graph and pass artifact names/versions to downstream stages.
+
+## PR vs CI Pipeline Differences
+
+PR pipelines:
+- Trigger on PRs targeting `release/7.1`; path filters vary by pipeline
+- Exception: the legacy `sqlclient-pr-package-ref-pipeline.yml` has an empty branch include list, so it has no PR trigger and is manual-queue only
+- Use reduced TFM matrix: `[net462, net8.0, net9.0]` (excludes net10.0)
+- Timeout: 90 minutes
+- Package-ref PR disables Always Encrypted tests in Debug config and also disables legacy SQL Server test legs to keep validation fast
+
+CI pipelines:
+- Trigger on push to `release/7.1` (GitHub) and `internal/release/7.1` (ADO) with `batch: true`
+- Exception: the legacy `dotnet-sqlclient-ci-package-reference-pipeline.yml` has its GitHub `release/7.1` push entry commented out, so only the ADO push trigger is active; its GitHub daily schedule still runs
+- Scheduled daily builds are staggered to avoid main and other release-branch schedules (see individual pipeline files for cron times)
+- Full TFM matrix including net10.0 test legs and legacy SQL Server manual-test coverage
 
 ## Test Configuration
 
-### Test Sets
-Tests are divided into sets for parallelization:
-- `TestSet=1` — First partition of tests
-- `TestSet=2` — Second partition
-- `TestSet=3` — Third partition
-- `TestSet=AE` — Always Encrypted tests
-
-### Test Filters
-Tests use category-based filtering. The default filter excludes both `failing` and `flaky` tests:
-```
-category!=failing&category!=flaky
-```
-
-Category values:
-- `nonnetfxtests` — Excluded on .NET Framework
-- `nonnetcoreapptests` — Excluded on .NET Core
-- `nonwindowstests` — Excluded on Windows
-- `nonlinuxtests` — Excluded on Linux
-- `failing` — Known permanent failures (excluded from all runs)
-- `flaky` — Intermittently failing tests (quarantined, run separately)
-
-### Flaky Test Quarantine in Pipelines
-Quarantined tests (`[Trait("Category", "flaky")]`) run in **separate pipeline steps** after the main test steps. This ensures:
-- Main test runs are **not blocked** by intermittent failures
-- Flaky tests are still **monitored** for regression or resolution
-- Code coverage is **not collected** for flaky test runs
-- Results appear in pipeline output for visibility
-
-The quarantine steps are configured in:
-- `eng/pipelines/common/templates/steps/build-and-run-tests-netcore-step.yml`
-- `eng/pipelines/common/templates/steps/build-and-run-tests-netfx-step.yml`
-- `eng/pipelines/common/templates/steps/run-all-tests-step.yml`
-
-### Test Timeout
-All test runs use `--blame-hang-timeout 10m` (configured in `build.proj`). Tests exceeding 10 minutes are killed and reported as failures.
-
-### SNI Testing
-The `useManagedSNI` parameter controls testing with:
-- Native SNI (`false`) - Windows native library
-- Managed SNI (`true`) - Cross-platform managed implementation
+Test partitioning:
+- Tests split into `TestSet=1`, `TestSet=2`, `TestSet=3` for parallelization
+- `TestSet=AE` — Always Encrypted tests (controlled by `runAlwaysEncryptedTests`)
 
-## Variables
-
-### Build Variables (`ci-build-variables.yml`)
-Common build configuration:
-- Package versions
-- Build paths
-- Signing configuration
-
-### Runtime Variables
-Set via pipeline parameters or UI:
-- `Configuration` - Debug/Release
-- `Platform` - AnyCPU/x86/x64
-- `TF` - Target framework
-
-## Creating Pipeline Changes
+Test filters — default excludes `failing` and `flaky` categories:
+- `failing` — known permanent failures, always excluded
+- `flaky` — intermittent failures, quarantined in separate pipeline steps
+- `nonnetfxtests` / `nonnetcoreapptests` — platform-specific exclusions
+- `nonwindowstests` / `nonlinuxtests` — OS-specific exclusions
 
-### Adding New Test Categories
-1. Add category attribute to tests: `[Category("newcategory")]`
-2. Update filter expressions in test job templates
-3. Document category purpose in test documentation
+Flaky test quarantine:
+- Quarantined tests (`[Trait("category", "flaky")]`) run in separate steps after main tests
+- Main test runs are not blocked by flaky failures
+- No code coverage collected for flaky runs
+- Configured in `common/templates/steps/build-and-run-tests-netcore-step.yml`, `build-and-run-tests-netfx-step.yml`, and `run-all-tests-step.yml`
 
-### Adding New Pipeline Parameters
-1. Define parameter in appropriate `.yml` file
-2. Add to parameter passing in calling templates
-3. Document in this file
+SNI testing — `useManagedSNI` controls testing with native SNI (`false`) or managed SNI (`true`)
 
-### Modifying Build Steps
-1. Changes should be made in template files for reusability
-2. Test changes locally when possible
-3. Submit as PR - validation will run
+Test timeout — `--blame-hang-timeout 10m` (configured in `build.proj` and threaded through CI test steps); tests exceeding 10 minutes are killed
 
-## Best Practices
-
-### Template Design
-- Use templates for reusable definitions
-- Pass parameters explicitly (avoid global variables)
-- Use descriptive stage/job/step names
-
-### Variable Management
-- Use template variables for shared values
-- Use pipeline parameters for per-run configuration
-- Avoid hardcoding versions (use Directory.Packages.props)
+## Variables
 
-### Test Infrastructure
-- Ensure tests are properly categorized
-- Handle test configuration files properly
-- Use test matrix for cross-platform coverage
+- All CI build variables centralized in `libraries/ci-build-variables.yml`
+- Package versions use `-ci` suffix (e.g., `7.0.0.$(Build.BuildNumber)-ci`)
+- `assemblyBuildNumber` derived from first segment of `Build.BuildNumber` (16-bit safe)
+- `localFeedPath` = `$(Build.SourcesDirectory)/packages` — local NuGet feed for inter-package deps
+- `packagePath` = `$(Build.SourcesDirectory)/output` — NuGet pack output
 
-## Troubleshooting
+## Variable Naming — Avoid `{COMMAND}ARGUMENTS` Names
 
-### Common Issues
-1. **Test failures due to missing config**: Ensure `config.json` exists
-2. **Platform-specific failures**: Check platform exclusion categories
-3. **Timeout issues**: Increase `testJobTimeout` parameter
+The dotnet CLI (via System.CommandLine) reads environment variables named `{COMMAND}ARGUMENTS` and silently injects their content into the parsed arguments for that subcommand. Because Azure DevOps automatically exposes all pipeline variables as uppercased environment variables, a pipeline variable named `runArguments` becomes `RUNARGUMENTS`, which `dotnet run` reads and injects into the application's `args[]` — bypassing the `--` separator.
 
-### Debugging Pipelines
-- Enable debug mode via `debug: true` parameter
-- Use `dotnetVerbosity: diagnostic` for detailed output
-- Check build logs in Azure DevOps
+**Forbidden variable names** (any casing):
+- `runArguments` — injected into `dotnet run`
+- `buildArguments` — injected into `dotnet build`
+- `testArguments` — injected into `dotnet test`
+- Any name matching `{dotnet-subcommand}Arguments`
 
-## Security Considerations
+**Use instead**: `dotnetBuildOpts`, `dotnetRunOpts`, `stressTestArgs`, or other names that do not match the `{COMMAND}ARGUMENTS` pattern.
 
-- Pipelines use service connections for artifact publishing
-- Signing uses secure key vault integration
-- Sensitive configuration should use pipeline secrets
-- Never commit credentials in pipeline files
+This affects ALL .NET SDK versions (8.0+). The injection is invisible in `[command]` log lines, making it extremely hard to diagnose. The only symptom is the application receiving unexpected arguments.

+- Always use templates for reusable logic — do not inline complex steps
+- Pass parameters explicitly; avoid relying on global variables
+- Use descriptive stage/job/step display names
+- When adding parameters, define them in the core template and thread through calling pipelines
+- When adding test categories, update filter expressions in test step templates
+- PR pipelines should run a minimal matrix for fast feedback
+- Test changes via PR pipeline first — validation runs automatically
+- Enable `debug: true` and `dotnetVerbosity: diagnostic` for troubleshooting
+- Never commit credentials or secrets in pipeline files
+- Signing and release are handled by OneBranch pipelines — not these CI/PR pipelines

+# Azure DevOps Work Items: Markdown Description Rules
+
+Use this guide whenever creating or updating Azure DevOps work items that include rich text in `System.Description`.
+
+## Goals
+
+- Ensure descriptions render as Markdown (not HTML/plain text)
+- Preserve newline characters and list structure
+- Verify work items after every batch update
+
+## Required Behavior
+
+1. Always use `az rest` for description content-type changes.
+2. Use `application/json-patch+json` for PATCH requests.
+3. Set `multilineFieldsFormat.System.Description` to `markdown`.
+4. Preserve exact newlines in the Markdown body.
+5. Verify both format and newline integrity after updates.
+
+## Authentication and Resource
+
+Use Azure DevOps resource audience when calling `az rest`:
+
+- Resource: `499b84ac-1321-427f-aa17-267ca6975798`
+
+Example auth check:
+
+```bash
+az rest \
+  --method GET \
+  --resource 499b84ac-1321-427f-aa17-267ca6975798 \
+  --url "https://dev.azure.com/<org>/_apis/projects?api-version=7.1-preview.4"
+```
+
+Note: API versions can differ by endpoint. The examples below use `7.1-preview.3` for work item PATCH calls, while this auth check uses `7.1-preview.4`.
+
+## Safe Update Pattern (Prevents Type/Value Errors)
+
+Some work items reject a direct type switch unless a valid value is provided. Use this two-step process:
+
+### Step 1: Capture current description
+
+```bash
+az boards work-item show --id <id> | jq -j '.fields["System.Description"] // ""' > ./desc-backup.txt
+```
+
+> **NOTE**: Writing to a file preserves all characters including trailing newlines.
+> Command substitution (`$(...)`) silently strips trailing newlines, which would
+> corrupt multi-line Markdown content.
+
+### Step 2: Force markdown type with temporary empty value
+
+```bash
+PATCH_STEP1_FILE="${PATCH_STEP1_FILE:-./patch-step1.json}"
+
+jq -n '[
+  {"op":"replace","path":"/fields/System.Description","value":""},
+  {"op":"replace","path":"/multilineFieldsFormat/System.Description","value":"markdown"}
+]' >"$PATCH_STEP1_FILE"
+
+az rest \
+  --method PATCH \
+  --resource 499b84ac-1321-427f-aa17-267ca6975798 \
+  --url "https://dev.azure.com/<org>/<project>/_apis/wit/workitems/<id>?api-version=7.1-preview.3" \
+  --headers "Content-Type=application/json-patch+json" \
+  --body @"$PATCH_STEP1_FILE"
+```
+
+### Step 3: Restore exact Markdown text
+
+```bash
+PATCH_STEP2_FILE="${PATCH_STEP2_FILE:-./patch-step2.json}"
+
+jq -n --rawfile d ./desc-backup.txt '[
+  {"op":"replace","path":"/fields/System.Description","value":$d}
+]' >"$PATCH_STEP2_FILE"
+
+az rest \
+  --method PATCH \
+  --resource 499b84ac-1321-427f-aa17-267ca6975798 \
+  --url "https://dev.azure.com/<org>/<project>/_apis/wit/workitems/<id>?api-version=7.1-preview.3" \
+  --headers "Content-Type=application/json-patch+json" \
+  --body @"$PATCH_STEP2_FILE"
+```
+
+## Newline Integrity Checks
+
+After updates, confirm newline characters are still present and structure was not flattened.
+
+### Check format and description sample
+
+```bash
+az boards work-item show --id <id> | jq '.multilineFieldsFormat, .fields["System.Description"][0:200]'
+```
+
+Expected:
+
+- `multilineFieldsFormat.System.Description == "markdown"`
+- Description text contains `\n` where line breaks are expected
+
+### Check line count did not collapse
+
+```bash
+az boards work-item show --id <id> \
+| jq -r '.fields["System.Description"]' \
+| awk 'END { print NR }'
+```
+
+If a multi-line description unexpectedly returns `1`, newline content was likely lost.
+
+## Batch Verification Script
+
+Use this after bulk updates:
+
+```bash
+python3 - <<'PY'
+import json, subprocess
+ids = [12345, 12346]  # replace with your target IDs
+bad = []
+for i in ids:
+    out = subprocess.check_output(["az", "boards", "work-item", "show", "--id", str(i)], text=True)
+    j = json.loads(out)
+    fmt = (j.get("multilineFieldsFormat") or {}).get("System.Description")
+    desc = j.get("fields", {}).get("System.Description") or ""
+    if fmt != "markdown" or "\n" not in desc:
+        bad.append((i, fmt, "has_newlines" if "\n" in desc else "missing_newlines"))
+print("noncompliant:", len(bad))
+for row in bad:
+    print(row)
+PY
+```
+
+## Common Failure Modes
+
+- `401` or `TF400813`: wrong token audience or insufficient auth context
+- `Content-Type ... not supported`: must use `application/json-patch+json`
+- `type changed without a value`: use two-step pattern (empty + markdown type, then restore text)

+---
+
+# Agentic Workflow Edit Rules (`gh aw`)
+
+This repository authors GitHub Actions agentic workflows in Markdown using
+[`gh aw`](https://github.com/githubnext/gh-aw). Each workflow `.md` file under
+`.github/workflows/` compiles to a sibling `.lock.yml`, and **only the
+`.lock.yml` is executed by GitHub Actions at runtime.**
+
+## Mandatory rule
+
+Whenever you create, edit, rename, or delete a file matching
+`.github/workflows/**/*.md`, you **MUST**, in the **same commit / PR**:
+
+1. Run `gh aw compile` from the repository root.
+2. Stage and commit the regenerated sibling `<name>.lock.yml`.
+3. If you deleted a workflow `.md`, also delete its `.lock.yml`.
+
+If the `.lock.yml` is stale or missing, the workflow fails at runtime
+(see PR #4279 for the exact failure mode). The
+`Verify gh aw lock files` CI check will block the PR in that case.
+
+## How to verify locally
+
+```bash
+gh aw compile
+git status        # both the .md and .lock.yml should appear
+gh aw compile     # second run must be a no-op (clean diff)
+```
+
+## Code-review checklist
+
+When reviewing a PR that touches `.github/workflows/**/*.md`:
+
+- [ ] A matching `.lock.yml` is updated in the same PR.
+- [ ] `gh aw compile` produces no further diff on top of the PR.
+- [ ] If new tools, network endpoints, or permissions are added in the `.md`,
+      they are present in the regenerated `.lock.yml`.
+
+## Out of scope
+
+- Do **not** hand-edit `.lock.yml` files. They are generated; edit the `.md`
+  source and recompile.
+- For deeper authoring guidance (creating, debugging, upgrading workflows),
+  invoke the `agentic-workflows` agent at
+  `.github/agents/agentic-workflows.agent.md`.

-# Multi-Product Azure DevOps Pipeline in dotnet/sqlclient — Design Specification
-
-## 1. Overview
-
-This document describes the design of the unified Azure DevOps YAML pipeline that builds, signs, packages, and optionally releases six NuGet packages with interdependencies. The pipeline uses **stages** and **jobs** to maximize parallelism while respecting dependency order. It comprises five stages: three build stages, a validation stage, and an on-demand release stage.
-
-Two pipeline variants exist from the same stage/job structure:
-
-| Pipeline | Template | Trigger | Purpose |
-|----------|----------|---------|---------|
-| `dotnet-sqlclient-official-pipeline.yml` | `OneBranch.Official.CrossPlat.yml` | CI + scheduled | Production-signed builds |
-| `dotnet-sqlclient-non-official-pipeline.yml` | `OneBranch.NonOfficial.CrossPlat.yml` | Manual only | Validation / test builds (release in dry-run mode) |
-
-Both pipelines use the **OneBranch (1ES) governed template** infrastructure and share identical stage definitions, job templates, and variable chains.

-## 4. Stage Design
-
-### 4.1 Build Phase
-
-The build phase runs automatically on every CI trigger, scheduled run, or manual queue. It is divided into four build stages plus a validation stage, based on the dependency graph.
-
-#### Stage 1 — `build_independent`: Independent Packages (no dependencies)
-
-| Job Template | Package | Build Target | Condition |
-|--------------|---------|--------------|-----------|
-| `build-signed-csproj-package-job.yml` | `Microsoft.Data.SqlClient.Internal.Logging` | `BuildLogging` / `PackLogging` | `buildAKVProvider OR buildSqlClient` |
-| `build-signed-csproj-package-job.yml` | `Microsoft.SqlServer.Server` | `PackSqlServer` | `buildSqlServerServer` |
-
-- **`dependsOn`**: none
-- **Parallelism**: Jobs run in parallel (depending on which are enabled)
-- **Conditional builds**: Each job is wrapped with compile-time `${{ if }}` conditionals based on build parameters
-- csproj-based jobs (`build-signed-csproj-package-job.yml`) perform: **Build DLLs → ESRP DLL signing → NuGet pack (NoBuild=true) → ESRP NuGet signing** → publish artifact
-
-#### Stage 2 — `build_abstractions`: Abstractions Package (depends on Stage 1)
-
-| Job Template | Package | Build Target | Artifact Dependencies |
-|--------------|---------|--------------|----------------------|
-| `build-signed-csproj-package-job.yml` | `Microsoft.Data.SqlClient.Extensions.Abstractions` | `BuildAbstractions` / `PackAbstractions` | `Internal.Logging` |
-
-- **Stage condition**: `buildSqlClient = true` (entire stage is excluded when false)
-- **`dependsOn`**: `build_independent`
-- Downloads `Microsoft.Data.SqlClient.Internal.Logging.nupkg` (from Stage 1) pipeline artifact
-
-#### Stage 3 — `build_dependent`: Core Packages (depend on Stage 2)
-
-| Job Template | Package | Build Target | Artifact Dependencies |
-|--------------|---------|--------------|----------------------|
-| `build-signed-package-job.yml` | `Microsoft.Data.SqlClient` | *(nuspec-based)* | `Internal.Logging`, `Extensions.Abstractions` |
-| `build-signed-csproj-package-job.yml` | `Microsoft.Data.SqlClient.Extensions.Azure` | `BuildAzure` / `PackAzure` | `Extensions.Abstractions`, `Internal.Logging` |
-
-- **Stage condition**: `buildSqlClient = true` (entire stage is excluded when false)
-- **`dependsOn`**: `build_abstractions`
-- **Parallelism**: Both jobs run in parallel
-- The MDS (SqlClient) job also publishes symbol packages (`.snupkg`) when `publishSymbols` is true
-- All jobs configure APIScan with job-level `ob_sdl_apiscan_*` variables targeting package-specific folders
-
-#### Stage 4 — `build_addons`: Add-on Packages (depend on Stage 3)
-
-| Job Template | Package | Artifact Dependencies |
-|--------------|---------|----------------------|
-| `build-akv-official-job.yml` | `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider` | `SqlClient`, `Internal.Logging` |
-
-- **Stage condition**: `buildAKVProvider AND buildSqlClient` (both must be true)
-- **`dependsOn`**: `build_dependent`
-- Downloads `Microsoft.Data.SqlClient.nupkg` (from Stage 3) and `Microsoft.Data.SqlClient.Internal.Logging.nupkg` (from Stage 1) pipeline artifacts
-- Uses separate ESRP signing credentials (`Signing`-prefixed variables from `esrp-variables-v2` group)
-
-### 4.2 Validation Stage — `mds_package_validation`
-
-Validates the signed MDS (SqlClient) package after Stage 3 completes.
-
-- **Stage condition**: `buildSqlClient = true`
-- **`dependsOn`**: `build_dependent`
-- Runs in parallel with Stage 4 (`build_addons`)
-- Uses `validate-signed-package-job.yml` template
-- Downloads the `drop_build_dependent_build_signed_package` artifact and validates against `CurrentNetFxVersion` (default: `net462`)
-
-### 4.3 Release Phase — `release`
-
-The release stage is gated and only executes on demand when at least one release parameter is set to `true` at queue time.
-
-- **`dependsOn`**: Conditional based on which build stages are enabled:
-  - `build_independent` (when releasing SqlServer.Server or Logging)
-  - `build_abstractions` (when releasing Abstractions)
-  - `build_dependent`, `mds_package_validation` (when `buildSqlClient = true`)
-  - `build_addons` (when `buildAKVProvider AND buildSqlClient`)
-- **Gate**: ADO Environment approvals (official pipeline only):
-  - Official: `NuGet-Production` environment with configured approvals
-  - Non-Official: `NuGet-DryRun` environment (no approvals, validation only)
-- **Package selection**: Controlled by 6 runtime boolean parameters (see Section 5.2)
-- **Stage condition**: The entire stage is skipped unless at least one release parameter is `true`:
-  ```yaml
-  - ${{ if or(parameters.releaseSqlServerServer, parameters.releaseLogging, ...) }}:
-    - stage: release
-  ```
-- **Publish jobs**: Each package has a conditional publish job that is included at compile time only when its parameter is `true`:
-  ```yaml
-  - ${{ if eq(parameters.releaseXxx, true) }}:
-    - template: /eng/pipelines/onebranch/jobs/publish-nuget-package-job.yml@self
-  ```
-- **Environment variables**: Stage sets `ob_release_usedeploymentjob: true` for OneBranch integration:
-  - Official: `ob_release_environment: 'NuGet-Production'`
-  - Non-Official: `ob_release_environment: 'NuGet-DryRun'`
-
-#### Artifact → Publish Job Mapping
-
-| Package | Artifact Name | Publish Job |
-|---------|---------------|-------------|
-| `Microsoft.SqlServer.Server` | `drop_build_independent_build_package_SqlServer` | `publish_SqlServer_Server` |
-| `Microsoft.Data.SqlClient.Internal.Logging` | `drop_build_independent_build_package_Logging` | `publish_Logging` |
-| `Microsoft.Data.SqlClient.Extensions.Abstractions` | `drop_build_abstractions_build_package_Abstractions` | `publish_Abstractions` |
-| `Microsoft.Data.SqlClient` | `drop_build_dependent_build_package_SqlClient` | `publish_SqlClient` |
-| `Microsoft.Data.SqlClient.Extensions.Azure` | `drop_build_dependent_build_package_Azure` | `publish_Extensions_Azure` |
-| `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider` | `drop_build_addons_buildSignedAkvPackage` | `publish_AKVProvider` |
-
-Each publish job uses the reusable `publish-nuget-package-job.yml` template, which downloads the artifact and pushes `.nupkg`/`.snupkg` files via `NuGetCommand@2` with an external feed service connection.
-
-#### Dry-Run Mode
-
-Two ADO environments control release behavior:
-
-| Environment | Pipeline | Behavior |
-|------------|----------|----------|
-| `NuGet-DryRun` | Non-Official | Validation only — packages are never pushed |
-| `NuGet-Production` | Official | Real releases with approval gate |
-
-**Non-official pipeline**: Always runs in dry-run mode. There is no `releaseDryRun` parameter — `dryRun: true` is hardcoded in every publish job. This prevents accidental publication from validation builds.
-
-**Official pipeline**: Exposes a `releaseDryRun` parameter (default: `true` for safety). When enabled, the template downloads artifacts and lists the `.nupkg`/`.snupkg` files that *would* be published but skips the actual `NuGetCommand@2` push. Set `releaseDryRun: false` to perform real pushes after final validation.
-
----
-
-## 5. Runtime Parameters
-
-### 5.1 Build Parameters
-
-The pipeline exposes the following parameters at queue time:
-
-```yaml
-parameters:
-  - name: debug
-    displayName: 'Enable debug output'
-    type: boolean
-    default: false
-
-  - name: publishSymbols
-    displayName: 'Publish symbols'
-    type: boolean
-    default: false
-
-  - name: CurrentNetFxVersion
-    displayName: 'Lowest supported .NET Framework version (MDS validation)'
-    type: string
-    default: 'net462'
-
-  - name: isPreview
-    displayName: 'Is this a preview build?'
-    type: boolean
-    default: false
-
-  - name: testJobTimeout
-    displayName: 'Test job timeout (in minutes)'
-    type: number
-    default: 60
-
-  # Build parameters — control which packages to build
-  - name: buildSqlServerServer
-    displayName: 'Build Microsoft.SqlServer.Server'
-    type: boolean
-    default: true
-
-  - name: buildSqlClient
-    displayName: 'Build Microsoft.Data.SqlClient and Extensions'
-    type: boolean
-    default: true
-
-  - name: buildAKVProvider
-    displayName: 'Build Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider'
-    type: boolean
-    default: true
-```
-
-The `isPreview` parameter controls version resolution — when `true`, each package uses its preview version (e.g., `loggingPackagePreviewVersion`) instead of the GA version (e.g., `loggingPackageVersion`). All versions are defined in the centralized `libraries/common-variables.yml`.
-
-The build parameters enable selective package building:
-- `buildSqlServerServer` — controls SqlServer.Server build job
-- `buildSqlClient` — controls MDS, Extensions.Azure, Abstractions, Logging (when AKV is disabled), and validation stages
-- `buildAKVProvider` — controls AKV Provider build (also requires `buildSqlClient=true`) and Logging (when SqlClient is disabled)
-
-When set to `false`, the respective jobs/stages are excluded at compile-time using `${{ if }}` conditionals. This allows faster pipeline runs when only certain packages need to be built.
-
-### 5.2 Release Parameters
-
-Six boolean parameters control selective package release. All default to `false` so the release stage is skipped on normal CI/scheduled builds:
-
-```yaml
-parameters:
-  - name: releaseSqlServerServer
-    displayName: 'Release Microsoft.SqlServer.Server'
-    type: boolean
-    default: false
-
-  - name: releaseLogging
-    displayName: 'Release Microsoft.Data.SqlClient.Internal.Logging'
-    type: boolean
-    default: false
-
-  - name: releaseAbstractions
-    displayName: 'Release Microsoft.Data.SqlClient.Extensions.Abstractions'
-    type: boolean
-    default: false
-
-  - name: releaseSqlClient
-    displayName: 'Release Microsoft.Data.SqlClient'
-    type: boolean
-    default: false
-
-  - name: releaseAzure
-    displayName: 'Release Microsoft.Data.SqlClient.Extensions.Azure'
-    type: boolean
-    default: false
-
-  - name: releaseAKVProvider
-    displayName: 'Release Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider'
-    type: boolean
-    default: false
-```
-
-#### Dry-Run Parameter (Official Pipeline Only)
-
-The **official pipeline** includes a `releaseDryRun` parameter that defaults to `true` for safety:
-
-```yaml
-  - name: releaseDryRun
-    displayName: 'Release Dry Run (do not push to NuGet)'
-    type: boolean
-    default: true    # safety default — must explicitly disable for real releases
-```
-
-When `releaseDryRun: true`, publish jobs download artifacts and list packages but skip actual NuGet push. Set to `false` for production releases.
-
-> **Note**: The non-official pipeline does **not** expose this parameter — dry-run mode is hardcoded and cannot be disabled.
-
----
-
-## 6. Variable & Version Management
-
-### 6.1 Variable Chain
-
-Variables are defined in a layered template chain. All variable groups live inside the templates — none are declared inline at the pipeline level:
-
-```
-dotnet-sqlclient-official-pipeline.yml
-  └─ libraries/variables.yml
-       └─ libraries/build-variables.yml
-            ├─ group: 'Release Variables'
-            ├─ group: 'Symbols publishing'          ← SymbolsPublishServer, SymbolsPublishTokenUri, etc.
-            └─ libraries/common-variables.yml
-                 ├─ group: 'ESRP Federated Creds (AME)'  ← ESRP signing credentials
-                 ├─ SymbolServer / SymbolTokenUri aliases ← mapped from Symbols publishing group
-                 └─ all package versions, paths, build variables
-```
-
-### 6.2 Package Version Variables
-
-All package versions are centralized in `libraries/common-variables.yml`:
-
-| Package | GA Version Var | Preview Version Var | Assembly Version Var |
-|---------|---------------|--------------------|--------------------|
-| Logging | `loggingPackageVersion` | `loggingPackagePreviewVersion` | `loggingAssemblyFileVersion` |
-| Abstractions | `abstractionsPackageVersion` | `abstractionsPackagePreviewVersion` | `abstractionsAssemblyFileVersion` |
-| SqlServer.Server | `sqlServerPackageVersion` | `sqlServerPackagePreviewVersion` | `sqlServerAssemblyFileVersion` |
-| SqlClient (MDS) | `mdsPackageVersion` | `mdsPackagePreviewVersion` | `mdsAssemblyFileVersion` |
-| Extensions.Azure | `azurePackageVersion` | `azurePackagePreviewVersion` | `azureAssemblyFileVersion` |
-| AKV Provider | `akvPackageVersion` | `akvPackagePreviewVersion` | `akvAssemblyFileVersion` |
-
-The pipeline resolves `effective*Version` variables at compile time based on the `isPreview` parameter.
-
-### 6.3 Release & Symbol Variables
-
-| Variable | Defined In | Purpose |
-|----------|-----------|---------|
-| `NuGetServiceConnection` | `libraries/common-variables.yml` | External NuGet service connection name for `NuGetCommand@2` push |
-| `SymbolServer` | `libraries/common-variables.yml` (alias) | Alias for `$(SymbolsPublishServer)` — used by MDS `publish-symbols-step.yml` |
-| `SymbolTokenUri` | `libraries/common-variables.yml` (alias) | Alias for `$(SymbolsPublishTokenUri)` — used by MDS `publish-symbols-step.yml` |
-
-### 6.4 Variable Groups
-
-| Group | Included In | Purpose |
-|-------|------------|---------|
-| `Release Variables` | `build-variables.yml` | Release-specific configuration |
-| `Symbols publishing` | `build-variables.yml` | Symbol publishing credentials (`SymbolsAzureSubscription`, `SymbolsPublishServer`, `SymbolsPublishTokenUri`, `SymbolsUploadAccount`, `SymbolsPublishProjectName`) |
-| `ESRP Federated Creds (AME)` | `common-variables.yml` | Federated identity for ESRP signing (`ESRPConnectedServiceName`, `ESRPClientId`, `AppRegistrationClientId`, `AppRegistrationTenantId`, `AuthAKVName`, `AuthSignCertName`) |
-
----
-
-## 7. Code Signing (ESRP)
-
-All packages are signed using **ESRP (Enterprise Security Release Pipeline)** with federated identity authentication.
-
-### Signing Flow (per job)
-
-#### csproj-based Extension Packages (Logging, Abstractions, Azure)
-1. **Build DLLs only** — `build.proj` target (e.g., `BuildLogging`) compiles assemblies without creating NuGet packages
-2. **ESRP DLL signing** — Assemblies are signed with Authenticode certificates via ESRP
-3. **NuGet pack** — `build.proj` pack target (e.g., `PackLogging`) creates `.nupkg` from signed DLLs using `NoBuild=true`
-4. **ESRP NuGet signing** — The `.nupkg` files are signed with NuGet certificates via ESRP
-
-This workflow ensures the NuGet package contains **signed DLLs** rather than signing the NuGet package around unsigned assemblies.
-
-#### nuspec-based Packages (SqlServer.Server, SqlClient, AKV Provider)
-1. **Build + pack** — MSBuild creates both assemblies and NuGet packages
-2. **ESRP DLL signing** — Assemblies are signed with Authenticode certificates via ESRP
-3. **ESRP NuGet signing** — The `.nupkg` files are signed with NuGet certificates via ESRP
-
-### Credential Model
-
-- Extension packages (Logging, Abstractions, Azure, SqlServer.Server, SqlClient) use the primary ESRP credentials from the `ESRP Federated Creds (AME)` variable group (loaded via `common-variables.yml`)
-- AKV Provider uses separate `Signing`-prefixed credential parameters that are passed explicitly to the `build-akv-official-job.yml` template
-- All credentials are sourced from Azure Key Vault and federated identity — no secrets stored in pipeline YAML
-
----
-
-## 8. SDL & Compliance (OneBranch)
-
-Both pipelines use **OneBranch governed templates** for 1ES compliance. The SDL configuration differs between Official and Non-Official:
-
-| SDL Tool | Official | Non-Official | Purpose |
-|----------|----------|--------------|---------|
-| **TSA** | ✅ `enabled: true` | ❌ `enabled: false` | Uploads SDL results to TSA for downstream analysis |
-| **ApiScan** | ✅ `enabled: true`, `break: true` | ✅ `enabled: true`, `break: true` | Scans APIs for compliance issues |
-| **CodeQL** | ✅ (non-preview) | ✅ (non-preview) | Static analysis for security vulnerabilities |
-| **SBOM** | ✅ (non-preview) | ✅ (non-preview) | Software Bill of Materials generation |
-| **Policheck** | ✅ `break: true` | ✅ `break: true` | Scans for policy-violating content |
-| **BinSkim** | ✅ (async, non-preview) | ✅ (async, non-preview) | Binary security analysis |
-| **CredScan** | ✅ (async, non-preview) | ✅ (async, non-preview) | Credential leak detection |
-| **Roslyn** | ✅ (async, non-preview) | ✅ (async, non-preview) | Roslyn-based security analyzers |
-| **Armory** | ✅ `break: true` | ✅ `break: true` | Additional security scanning |
-
-### APIScan Configuration
-
-APIScan is configured at **both pipeline level and job level**:
-
-**Pipeline-level** (`globalSdl:apiscan:`): Sets default configuration inherited by all jobs. This is configured for MDS (Microsoft.Data.SqlClient) as the primary product.
-
-**Job-level** (`ob_sdl_apiscan_*` variables): Each build job overrides the pipeline defaults with package-specific settings:
-
-| Variable | Purpose |
-|----------|---------|
-| `ob_sdl_apiscan_enabled` | Enable/disable APIScan for this job (`true`) |
-| `ob_sdl_apiscan_softwareFolder` | Path to signed DLLs for scanning |
-| `ob_sdl_apiscan_symbolsFolder` | Path to PDBs for scanning |
-| `ob_sdl_apiscan_softwarename` | Package name (e.g., `Microsoft.Data.SqlClient.Internal.Logging`) |
-| `ob_sdl_apiscan_versionNumber` | Assembly file version |
-
-Each job copies its signed DLLs and PDBs to a package-specific folder under `$(Build.SourcesDirectory)/apiScan/<PackageName>/` after ESRP DLL signing, ensuring APIScan analyzes the correct signed binaries for each package.
-
-> **PRC Compliance**: The Official pipeline hardcodes `OneBranch.Official.CrossPlat.yml` (not parameterized) to satisfy Production Readiness Check static verification requirements.
-
----
-
-## 9. Artifact Strategy
-
-- Each build job publishes its output as a **pipeline artifact** managed by OneBranch's `ob_outputDirectory` convention.
-- Artifact names follow the OneBranch auto-generated pattern: `drop_<stageName>_<jobName>` (e.g., `drop_build_dependent_build_package_SqlClient`).
-- Downstream stages use `DownloadPipelineArtifact@2` to pull required packages into a local directory.
-- A local NuGet source is configured at build time pointing to the downloaded artifacts directory so `dotnet restore` resolves internal dependencies.
-
----
-
-## 10. Trigger Configuration
-
-### Official Pipeline (`dotnet-sqlclient-official-pipeline.yml`)
-
-```yaml
-trigger:
-  branches:
-    include:
-      - internal/main
-  paths:
-    include:
-      - .azuredevops
-      - .config
-      - doc
-      - eng/pipelines
-      - src
-      - tools
-      - azurepipelines-coverage.yml
-      - build.proj
-      - NuGet.config
-
-schedules:
-  - cron: '30 4 * * Mon'           # Weekly Sunday 9:30 PM (UTC-7)
-    branches: { include: [internal/main] }
-    always: true
-  - cron: '30 3 * * Mon-Fri'       # Weekday 8:30 PM (UTC-7)
-    branches: { include: [internal/main] }
-```
-
-- **CI trigger**: Runs on pushes to `internal/main` when relevant paths change
-- **Scheduled**: Weekly full build (Sundays) + weekday builds (Mon–Fri)
-- **No PR trigger**: Official pipeline should not run on PRs (separate PR pipelines exist)
-
-### Non-Official Pipeline (`dotnet-sqlclient-non-official-pipeline.yml`)
-
-```yaml
-trigger: none
-pr: none
-```
-
-- **Manual only**: Queued on-demand for validation/test builds
-
----
-
-## 11. Infrastructure
-
-| Concern | Implementation |
-|---------|---------------|
-| **Pipeline template** | OneBranch governed templates (`OneBranch.Pipelines/GovernedTemplates`) |
-| **Build agents** | OneBranch-managed Windows containers (`WindowsHostVersion: 1ESWindows2022`) |
-| **.NET SDK** | Pinned via `global.json` (with `useGlobalJson: true` in install steps) |
-| **Code signing** | ESRP v2 with federated identity (Azure Key Vault backed) |
-| **Symbol publishing** | Optional, controlled by `publishSymbols` parameter; uses `Symbols publishing` variable group (aliases `SymbolServer`/`SymbolTokenUri` defined in `common-variables.yml`) |
-
----
-
-## 12. Key Design Decisions
-
-1. **Single pipeline, multiple stages** — avoids managing 6 separate pipelines while keeping clear separation of concerns.
-2. **Official + Non-Official variants** — hardcoded OneBranch templates (no parameterized `oneBranchType`) for PRC compliance; Non-Official variant allows manual validation builds.
-3. **Parallel jobs within stages** — minimizes total wall-clock time; only waits where dependencies demand it.
-4. **Pipeline artifacts over Universal Packages** — faster, ephemeral, scoped to the run; appropriate for build-time dependency resolution.
-5. **ESRP-based code signing** — all DLLs and NuGet packages are signed in-pipeline using ESRP with federated identity; no secrets in YAML.
-6. **Centralized version management** — all 6 package versions (GA + preview) defined once in `libraries/common-variables.yml`; `isPreview` toggle selects the active set.
-7. **Dependency-aware stage ordering** — ensures packages are always built after their dependencies, guaranteeing consistent, reproducible builds.
-8. **Validation in parallel with Stage 3** — MDS package validation runs alongside AKV Provider build (both depend on Stage 2), reducing total pipeline duration.
-9. **Selective on-demand release** — 6 boolean parameters control which packages are published; the release stage is entirely skipped when none are selected, keeping normal CI builds unaffected.
-10. **ADO Environment approval gate** — two environments: `NuGet-Production` (official, with configured approvals) and `NuGet-DryRun` (non-official, validation only). Both use `ob_release_environment` for OneBranch integration.
-11. **Compile-time conditional publish jobs** — `${{ if eq(parameters.releaseXxx, true) }}` template expansion ensures unselected publish jobs are excluded entirely from the pipeline run (not just skipped at runtime).
-12. **Mandatory dry-run for non-official** — the non-official variant hardcodes `dryRun: true` (no parameter), preventing accidental publication. The official variant defaults `releaseDryRun: true` for safety but allows override for actual releases.
-13. **Selective build parameters** — `buildSqlClient`, `buildSqlServerServer`, and `buildAKVProvider` allow building subsets of packages, with dependency-aware conditionals ensuring Logging builds when either SqlClient or AKV is needed.
+# OneBranch Pipeline Guidelines
+
+## Purpose
+
+Rules and conventions for editing the OneBranch Azure DevOps YAML pipelines that build, sign, package, and release six NuGet packages with interdependencies.
+
+## Pipeline Variants
+
+- `sqlclient-official.yml` — Official pipeline; uses `OneBranch.Official.CrossPlat.yml`; runs on a daily schedule at 23:00 UTC on `internal/release/7.1`, with no activity-based trigger (`pr: none`, `trigger: none`)
+- `sqlclient-non-official.yml` — Non-Official pipeline; uses `OneBranch.NonOfficial.CrossPlat.yml`; manual only (`pr: none`, `trigger: none`)
+- Both live under `eng/pipelines/onebranch/` and extend OneBranch governed templates
+- Never parameterize the OneBranch template name — hardcode it per pipeline for PRC compliance
+- Official pipeline must never be run on PRs or dev branches.
+
+## Package Dependency Order
+
+Respect this graph when modifying build stages:
+
+1. `Microsoft.SqlServer.Server` — no dependencies
+2. `Microsoft.Data.SqlClient.Internal.Logging` — no dependencies
+3. `Microsoft.Data.SqlClient.Extensions.Abstractions` — depends on Logging
+4. `Microsoft.Data.SqlClient` — depends on Logging + Abstractions
+5. `Microsoft.Data.SqlClient.Extensions.Azure` — depends on Abstractions + Logging
+6. `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider` — depends on SqlClient + Abstractions + Logging
+
+## Localization Validation
+
+The SqlClient build job runs `steps/validate-localization-step.yml` before building the driver. Validation always fails the build for missing or obsolete keys, empty localized values whose English value is non-empty, and untranslated resources. Approved identical translations are listed by culture and resource key in `.config/LocalizationValidationAllowlist.json`.
+
+## Build Stages
+
+Defined in `stages/build-stages.yml`. Four build stages plus package validation are ordered by dependency:
+
+- **`build_independent`** (Stage 1) — Logging and SqlServer.Server in parallel; no inter-package dependencies
+- **`build_abstractions`** (Stage 2) — Abstractions; `dependsOn: build_independent`; downloads Logging artifact
+- **`build_dependent`** (Stage 3) — SqlClient and Extensions.Azure in parallel; `dependsOn: build_abstractions`; downloads Abstractions + Logging artifacts
+- **`build_addons`** (Stage 4) — AKV Provider; `dependsOn: build_dependent`; downloads SqlClient + Abstractions + Logging artifacts
+- **`package_validation`** (Stage 5) — Validates every package produced by the run; `dependsOn` all four build stages plus `compute_versions`
+
+Each build job copies PDB files into `$(JOB_OUTPUT)/symbols/` so they are included in the auto-published pipeline artifact alongside the NuGet packages in `$(JOB_OUTPUT)/packages/`.
+
+Stage conditional rules:
+- The SqlClient family (Logging, Abstractions, SqlClient, Azure, AKV Provider) is **always built** — Stages 2, 3, and 4 and the Logging job in Stage 1 are unconditional. There is no `buildSqlClient`/`buildAKVProvider` toggle.
+- `buildSqlServer` is the only build toggle; it controls just the SqlServer.Server job in Stage 1.
+- When `buildSqlServer` is true, SqlClient/AKV depend on the freshly-built SqlServer artifact (downloaded into the local feed). When false, they depend on the most recently published SqlServer package — a version-only dependency (no artifact download) restored from NuGet.
+
+## Job Templates
+
+- **`build-buildproj-job.yml`** — Shared build.proj-driven package job used for all shipped packages. Flow: build via `build.proj` → optional ESRP DLL signing → pack via `build.proj` → optional ESRP NuGet signing → copy outputs for APIScan/artifacts
+- **`validate-packages-job.yml`** — Validates every package produced by the run. Downloads all package artifacts into one tree and validates them together, so `tools/PackageValidator` can apply its cross-package rules (the SqlClient family must share one version, and inter-package dependency ranges must agree); validating per package would silently skip those findings. Runs on Windows because Authenticode verification has no Linux equivalent
+- **`publish-nuget-package-job.yml`** — Reusable release job using OneBranch `templateContext.type: releaseJob` with `inputs` for artifact download; pushes via `NuGetCommand@2`
+- **`publish-symbols-job.yml`** — Reusable symbols job: downloads a build artifact, locates PDBs under `symbols/`, and invokes `publish-symbols-step.yml`
+
+When adding a new package to the OneBranch flow:
+- Extend `build-buildproj-job.yml` inputs with the new package metadata and dependency artifacts
+- Add or update the corresponding build/pack targets in `build.proj`
+- Add version variables to `variables/common-variables.yml`
+- Add artifact name variables to `variables/onebranch-variables.yml`
+
+## Package Validation Stage
+
+- Defined in `stages/build-stages.yml`; produces stage `package_validation`
+- Consumes the package and file versions published by `compute_versions` and asserts the produced packages carry exactly those values, so nothing is re-derived
+- All packages are validated together in one job so `tools/PackageValidator` can apply cross-package rules; the SqlServer artifact and its expectations are conditional on `buildSqlServer`
+- Expectations use the validator's `[id=]value` form: the SqlClient family version is applied as a wildcard (proving the family agrees, and catching the case where all packages are consistently wrong), with `Microsoft.SqlServer.Server` as a per-id override
+- When SqlServer is not built its expectations are **omitted entirely** rather than passed empty — the validator rejects an expectation with an empty value
+- Gate categories are derived from `isOfficial`: `error`, `missing-symbols`, `dependency-inconsistency`, `delay-signed`, and `unsigned` always, plus `package-unsigned` on official runs only. The `error` severity covers only error-severity findings, so each warning/info category must be named explicitly — `missing-symbols`, `dependency-inconsistency`, and `delay-signed` are warnings, and `unsigned` and `package-unsigned` are info. Strong-name signing is unconditional in `build-buildproj-step.yml`, so the two strong-name categories gate everywhere; NuGet package signing is ESRP and official-only, so `package-unsigned` would fire on every non-official run
+- The validator runs twice: once with `--json` and no gate so the report exists even for a failing run, then once human-readable with the gate so failures appear in the job log
+- Signature verification (`dotnet nuget verify --all`, Authenticode) runs on official builds only, and verifies that signatures are *trusted* — PackageValidator reports only their presence, from metadata
+- The release stage `dependsOn: package_validation`, so a package that fails validation is never published
+- Step and job logic lives in `scripts/validate-packages.ps1`, `scripts/verify-package-signatures.ps1`, and `scripts/verify-assembly-signatures.ps1`, each with Pester tests under `scripts/tests/`
+
+## Symbols Publishing Stage
+
+- Defined in `stages/publish-symbols-stage.yml`; produces stage `publish_symbols`
+- Entire stage excluded at compile time when `publishSymbols` is false
+- The SqlClient family symbols are always published; the SqlServer.Server symbols job is conditional on `buildSqlServer`
+- `dependsOn` covers all family build stages (always present), plus `build_independent` for SqlServer
+- One job per package (`publish-symbols-job.yml`), each downloading its build artifact and publishing PDBs from `symbols/`
+- Each package's PDBs are published separately with unique artifact names and version information
+- Build jobs copy PDBs into `$(JOB_OUTPUT)/symbols/` so they are included in the auto-published artifact
+- The `publish-symbols-step.yml` accepts a `symbolsFolder` parameter to point at the downloaded PDB location
+- The publish step calls an extracted `publish-symbols.ps1` script with structured error handling and diagnostic logging
+- Symbols publishing credentials come from the `Symbols Publishing` variable group
+- In the official pipeline, symbol server destination follows `releaseToProduction`: Production when true, PPE when false
+- Non-official pipeline always targets the PPE symbol server
+
+## Release Stage
+
+- Defined in `stages/release-stages.yml`; produces stage `release_production` (official) or `release_test` (non-official) via `stageNameSuffix` parameter
+- Entire stage excluded at compile time when no release parameters are true
+- `dependsOn` is conditional based on which release parameters are set
+- `releaseToProduction` parameter controls NuGet target feed:
+  - `true` → service connection `ADO Nuget Org Connection` (NuGet Production)
+  - `false` → service connection `ADO Nuget Org Test Connection` (NuGet Test)
+- Non-official pipeline always sets `releaseToProduction: false`
+- Environment gating:
+  - Official: `ob_release_environment: Production`, `ob_deploymentjob_environment: NuGet-Production`
+  - Non-official: `ob_release_environment: Test`, `ob_deploymentjob_environment: NuGet-DryRun`
+- Each publish job uses OneBranch deployment job syntax (`templateContext.type: releaseJob` with `inputs` for artifact download)
+
+## Parameters
+
+Build parameters:
+- `debug` — enable debug output (default `false`)
+- `isPreview` — use preview version numbers (default `false`)
+- `publishSymbols` — publish symbols to servers (default `false`)
+- `buildSqlServer` — build the Microsoft.SqlServer.Server package (default `true` in the non-official/nightly pipeline, `false` in the official pipeline). The SqlClient family is always built, so this is the only build toggle. It also drives the SqlServer dependency version the family uses (built/next vs published). Requesting `releaseSqlServer` without `buildSqlServer` fails template expansion.
+
+Release parameters (boolean, default `false`):
+- `releaseSqlClient` — release the entire SqlClient family together (Logging, Abstractions, SqlClient, Azure, AKV Provider) at the shared version
+- `releaseSqlServer` — release Microsoft.SqlServer.Server (versioned separately)
+
+Official-only parameter:
+- `releaseToProduction` — controls both NuGet target feed and symbol server destination (default `false`):
+  - `true` → NuGet Production feed + Production symbol server
+  - `false` → NuGet Test feed + PPE symbol server
+
+When `isPreview` is true, pipeline resolves `effective*Version` variables to preview versions; otherwise GA versions. All versions defined in `variables/common-variables.yml`.
+
+## Variables and Versions
+
+- Variable chain: pipeline YAML → `variables/onebranch-variables.yml` → `variables/common-variables.yml`
+- All package versions (GA, preview, assembly file) centralized in `variables/common-variables.yml`
+- The `compute_versions` stage reads canonical versions from MSBuild and publishes effective package,
+  file-build, and APIScan registration versions for downstream stages
+- Artifact name variables defined in `variables/onebranch-variables.yml` following `drop_<stageName>_<jobName>` pattern
+- `assemblyBuildNumber` derived from first segment of `Build.BuildNumber` only (16-bit limit)
+- When adding a new package, add GA version, preview version, and assembly file version entries
+
+Variable groups:
+- `Symbols Publishing` — symbol publishing credentials (in `onebranch-variables.yml`)
+- `ESRP Federated Creds (AME)` — ESRP signing credentials (in `common-variables.yml`)
+
+## Code Signing (ESRP)
+
+- Uses ESRP v6 tasks (`EsrpMalwareScanning@6`, `EsrpCodeSigning@6`) with MSI/federated identity authentication
+- Signing only runs when `isOfficial: true` — non-official pipelines skip ESRP steps
+- The shared OneBranch job signs DLLs before packing and signs the resulting NuGet package afterward so the published package contains signed binaries
+- DLL signing uses keyCode `CP-230012` (Authenticode); NuGet signing uses keyCode `CP-401405`
+- All ESRP credentials come from variable groups — never hardcode secrets in YAML
+
+## SDL and Compliance
+
+- TSA: enabled only in official pipeline; disabled in non-official to avoid spurious alerts
+- ApiScan: enabled in both; `break` follows the `breakOnSdlError` parameter
+- Each package is registered with APIScan under its own name/version pair, so the `globalSdl.apiscan` blocks deliberately omit `softwareName`/`versionNumber`. `build-buildproj-job.yml` is the single place they are set, via `ob_sdl_apiscan_softwareName` (the package's `packageFullName`) and `ob_sdl_apiscan_versionNumber` (the `apiScanSoftwareVersion` parameter)
+- `compute-versions.ps1` derives APIScan registration versions as major.minor from the effective canonical package versions and publishes them as stage outputs. A package name/version pair must still be registered with APIScan before releasing a new major.minor. Consume these as runtime `$(...)` references so values such as `1.0` remain strings rather than being coerced to numbers by template expressions
+- Jobs that produce no assemblies (symbol publishing, signed-package validation, version computation) set `ob_sdl_apiscan_enabled: false` rather than reporting a name/version
+- Each build job also sets `ob_sdl_apiscan_softwareFolder` and `ob_sdl_apiscan_symbolsFolder` to its per-package `apiScan/<package>/dlls` and `apiScan/<package>/pdbs` paths
+- CodeQL, SBOM, Policheck (`break: true`): enabled in both pipelines
+- SBOM package name/version are resolvable **only** from the pipeline's `globalSdl.sbom` block — OneBranch's artifact-publishing path reads `globalSdl.sbom.packageName`/`packageVersion` directly and has no per-job equivalent (the `templateContext.sdl.sbom` override only applies to the native 1ES Stages entry point, which this repo does not use). Because the pipeline produces six differently-named and independently-versioned packages, `globalSdl.sbom` indirects through the `$(sbomPackageName)` / `$(sbomPackageVersion)` variables, which each build job sets to its own `packageFullName` and computed `packageVersion`. Jobs that publish no packages (version computation, symbol publishing) set `ob_sdl_sbom_enabled: false` alongside their existing APIScan/BinSkim opt-outs, so the variables never need pipeline-level defaults
+- asyncSdl `enabled: false` in both; individual sub-tools (CredScan, BinSkim, Armory, Roslyn) configured underneath
+- Policheck exclusions: `$(REPO_ROOT)\.config\PolicheckExclusions.xml`
+- CredScan suppressions: `$(REPO_ROOT)/.config/CredScanSuppressions.json`
+
+## Artifact Conventions
+
+- `ob_outputDirectory` set to `$(JOB_OUTPUT)` (= `$(REPO_ROOT)/output`) — OneBranch auto-publishes this directory
+- Each published artifact uses subdirectories to separate file types:
+  - `assemblies/` — DLL assemblies for APIScan (preserving TFM folder structure)
+  - `packages/` — NuGet packages (`.nupkg`, `.snupkg`)
+  - `symbols/` — PDB symbol files (preserving TFM folder structure, shared by APIScan and symbol publishing)
+- Artifact names follow `drop_<stageName>_<jobName>` — defined in `variables/onebranch-variables.yml`
+- Downstream jobs download artifacts via `DownloadPipelineArtifact@2` into `$(Build.SourcesDirectory)/packages`
+- Downloaded packages serve as a local NuGet source for `dotnet restore`
+- If stage or job names change, update artifact name variables in `onebranch-variables.yml`
+
+## Common Pitfalls
+
+- Do not use `PublishPipelineArtifacts` task — OneBranch auto-publishes from `ob_outputDirectory`
+- Do not add `NuGetToolInstaller@1` in OneBranch containers — NuGet is pre-installed
+- Variable templates are under `variables/` not `libraries/`
+- Always test parameter changes in the non-official pipeline first
+- When modifying stage names, update all `dependsOn` references and artifact name variables
+- Release jobs must use `templateContext.type: releaseJob` with `inputs` for artifact download — deployment jobs do not auto-download artifacts

+# Secrets and Credential Handling
+
+This guide describes how to avoid committing secrets, how to write credential
+placeholders that do **not** trip secret scanners (e.g. GitHub Advanced Security
+/ 1ES push protection), and what to do when a push is blocked.
+
+## Golden Rules
+
+1. **Never commit a real secret** — passwords, connection strings with live
+   credentials, access keys, SAS tokens, client secrets, certificates/PFX
+   files, or bearer tokens. This applies to source, tests, docs, samples,
+   scripts, pipeline YAML, and config files.
+2. **Never route a secret through tooling or the model.** When a value is truly
+   secret, have the user type it directly into their terminal or set it as an
+   environment variable. Do not paste it into files, prompts, or chat.
+3. **Prefer indirection over literals.** Read credentials from environment
+   variables, a secret store (Azure Key Vault), user secrets, or CI secret
+   variables — not from committed text.
+4. **Assume public.** This repository mirrors to public GitHub via autosync.
+   Anything committed is effectively public and permanent in history.
+
+## Approved Placeholder Formats
+
+When you need to show the *shape* of a connection string or credential in code,
+docs, comments, or samples, use one of these placeholder styles. These are
+recognized as non-secrets by the scanner:
+
+| Style | Example | Use for |
+|-------|---------|---------|
+| Angle brackets | `User ID=<user>;Password=<pwd>` | Docs, READMEs, comments, samples |
+| Descriptive angle brackets | `Password=<myPassword>`, `User Id=<AppId>` | Samples that name the value |
+| Masked | `Password=********` or `Password=***` | Illustrative output / redaction |
+| Env var expansion | `Password=${SA_PASSWORD}` (bash), `Password=$(SqlPwd)` (ADO) | Scripts and pipelines |
+| Named token (docs prose) | `Password=<Secret>` | Narrative documentation |
+
+### Do NOT use these placeholder styles
+
+- **Ellipsis values** — a `Password` (or `Pwd`) key whose value is a literal
+  ellipsis, especially when paired with a `User ID` key in the same connection
+  string. The ellipsis is treated as a credential value and **will** trip
+  `SEC101/037 SqlLegacyCredentials`. Use `<pwd>` instead.
+- **Realistic-looking fake secrets** — a `Password` key set to a value that
+  looks like a real password (mixed letters, digits, and symbols). Even fake
+  values that resemble real passwords can be flagged and set a bad example.
+- **Bare word secrets** — a `Password` key set to a plain dictionary word
+  inside a connection-string literal. Prefer `<pwd>`.
+
+> **NOTE**: Ironically, this document cannot show verbatim examples of the
+> disallowed styles above — spelling out a `Password` key followed by an
+> ellipsis or realistic-looking value would itself trip `SEC101/037` and block
+> commits to this very file. That is exactly why the "don't" cases are described
+> in prose rather than shown literally.
+
+### Full connection-string placeholder examples
+
+```text
+Server=<server>;Database=<db>;User ID=<user>;Password=<pwd>;TrustServerCertificate=true
+Server=tcp:<servername>.database.windows.net;Database=<dbname>;Authentication=Active Directory Service Principal;User Id=<AppId>;Password=<Secret>
+```
+
+```bash
+# Have the user set the value directly; never write the real value into a file:
+export SNICLOSE_CONNSTR="Server=<server>;User ID=<user>;Password=<pwd>"
+```
+
+## Reading Secrets at Runtime (preferred patterns)
+
+- **Environment variables**: read connection strings from an env var
+  (e.g. `SNICLOSE_CONNSTR`) so the password never lands in a committed file.
+- **SecureString / SqlCredential**: use `SqlCredential` and `SecureString`
+  rather than embedding a password in the connection string.
+- **Integrated auth**: prefer `Integrated Security=true` or an
+  `Authentication=ActiveDirectory*` mode where no password is stored.
+- **CI/CD**: reference pipeline secret variables (`$(mySecret)`), never inline
+  literals in YAML.
+
+## When a Push Is Blocked by Secret Scanning
+
+Error shape: `VS403654:BypassableBlock ... push was rejected because it contains
+one or more secrets` with a `SEC101/...` rule id and `commit`/`paths` details.
+
+1. **Locate it.** Inspect the exact committed blob:
+   `git show <commit>:<path>` and go to the reported line/columns.
+2. **Determine real vs. false positive.**
+   - *Real secret*: rotate/revoke it immediately, then remove it from the file.
+     If it is in the tip commit only, amend; if it is deeper in **unshared**
+     history, rewrite that history. Never rewrite commits already public.
+   - *False positive* (an ellipsis or other non-credential placeholder value):
+     reword to an approved placeholder (`Password=<pwd>`) so future commits
+     don't recur.
+3. **Already-public / mirrored commits.** If the flagged content lives in a
+   commit that is already on public GitHub (e.g. an autosync mirror replaying
+   `github/main`), you cannot scrub that specific commit without rewriting
+   shared/public history. For a confirmed false positive, **bypass** the block
+   via the 1ES/Advanced Security push-protection flow
+   (https://aka.ms/1esSecretScanning/PushProtectionBypassableBlock) with a clear
+   reason, or dismiss the alert as *False positive*. Then land the placeholder
+   reword going forward so new files don't trip the rule again.
+4. **Never** disable secret scanning or use `--no-verify`-style bypasses to work
+   around a *real* secret.
+
+## Common Scanner Rules to Watch
+
+| Rule | Triggers on |
+|------|-------------|
+| `SEC101/037 SqlLegacyCredentials` | Connection strings pairing a `User ID` key with a `Password`/`Pwd` value |
+| `SEC101/*` (general) | Cloud keys, SAS tokens, client secrets, PATs, bearer tokens |
+
+If in doubt, use an approved placeholder from the table above.

+# SqlClient Package Version Resolution
+
+How package versions are determined across different build scenarios for the packages in this repository.
+
+## Package families
+
+The repository ships two independently-versioned units:
+
+- **The SqlClient family** — `Microsoft.Data.SqlClient` plus the packages that version in lockstep with
+  it: `Microsoft.Data.SqlClient.Internal.Logging`, `Microsoft.Data.SqlClient.Extensions.Abstractions`,
+  `Microsoft.Data.SqlClient.Extensions.Azure`, and
+  `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`.  **All family packages use the
+  SqlClient version numbers** — the same NuGet package version, file version, and assembly version —
+  and are always built and released together.
+- **`Microsoft.SqlServer.Server`** — versioned and released on its own cadence.
+
+## Version Properties
+
+The SqlClient family version lives in `src/Microsoft.Data.SqlClient/Versions.props`, which is imported
+for every project by `src/Directory.Build.props` (so the `SqlClient*` version properties are always
+available).  `Microsoft.SqlServer.Server` declares its own version in its own `Versions.props`.
+
+| Property | Applies to | Purpose | Example |
+|----------|-----------|---------|---------|
+| `SqlClientNextVersion` | SqlClient family | Version being developed; used for the next release | `7.1.0-preview1` |
+| `SqlServerNextVersion` | SqlServer | Version being developed for SqlServer | `1.1.0-preview1` |
+| `SqlServerPublishedVersion` | SqlServer | Last SqlServer version shipped to NuGet | `1.0.0` |
+
+The SqlClient family always ships its next version, so there is **no** family `PublishedVersion`.  Only
+`Microsoft.SqlServer.Server` keeps a published version (used when it is built as a SqlClient dependency
+but not itself released).
+
+## Resolution Logic
+
+Each `Versions.props` uses a 3-tier `<Choose>` block:
+
+| Priority | Condition | PackageVersion | FileVersion |
+|----------|-----------|----------------|-------------|
+| 1 | `<Pkg>PackageVersion` explicitly provided | Used as-is | Strip prerelease + append BuildNumber |
+| 2 | `BuildNumber` provided (non-zero) | `NextVersion[-BuildSuffix]`, then `.BuildNumber` appended if that carries a prerelease tag | `NextVersion.Split('-')[0].BuildNumber` |
+| 3 | Nothing provided | `NextVersion-dev` | `NextVersion.Split('-')[0].0` |
+
+For every family package, `<Pkg>` is `SqlClient` (e.g. `-p:SqlClientPackageVersion=...`); for
+Microsoft.SqlServer.Server it is `SqlServer`.
+
+> **Two equivalent names for the same value.** `SqlClientPackageVersion` / `SqlServerPackageVersion`
+> are the underlying project properties (read by `Versions.props`, `Directory.Packages.props`, the
+> csproj files, and the nuspec). When building through `build.proj` — which the CI and OneBranch
+> pipelines always do — pass the wrapper argument `-p:PackageVersionSqlClient=...` /
+> `-p:PackageVersionSqlServer=...`; `build.proj` forwards it to the underlying
+> `-p:SqlClientPackageVersion=...` / `-p:SqlServerPackageVersion=...`. Both set the same value —
+> pipeline logs show `PackageVersion<Pkg>`, while project builds and props show `<Pkg>PackageVersion`.
+
+### Developer (local `dotnet build`)
+
+**Mode:** Project (default `ReferenceType=Project`)
+
+- No `BuildNumber`, no `BuildSuffix`, no `PackageVersion*` passed.
+- Falls into Priority 3 (the `<Otherwise>` branch).
+- **Result:** `7.1.0-preview1-dev` / FileVersion `7.1.0.0`
+- Dependencies are project references — no package versions needed for siblings.
+
+**Mode:** Package (`-p:ReferenceType=Package`)
+
+- Same version resolution for the package being built.
+- Sibling dependencies are restored from local `packages/` feed (previously packed with `-dev` suffix).
+- A developer would first `dotnet build build.proj -t:Pack` to produce local packages, then consume them.
+
+### PR Pipeline (non-official CI)
+
+**`buildSuffix`** set via core template parameter:
+- `buildSuffix: 'pr'` (passed explicitly from PR pipeline)
+- `BuildNumber` = `$(DayOfYear)$(Rev:rr)` (e.g. `15401` for day-of-year 154, run 01)
+
+**Mode:** Project (typical PR validation)
+
+- Versions computed in `compute-versions-ci-stage.yml` (runs `GetVersions*` targets with `-p:BuildSuffix=pr -p:BuildNumber=...`)
+- Falls into Priority 2 with BuildSuffix present.
+- **Result:** `7.1.0-preview1-pr.15401` / FileVersion `7.1.0.15401`
+- Dependencies are project references — all packages built together in-tree.
+
+**Mode:** Package (PR package-ref validation)
+
+- Same version computation via compute-versions stage.
+- Downstream stages define stage-level variables from compute-versions output using `$[ stageDependencies... ]`.
+- Each build step passes the family wrapper argument `-p:PackageVersionSqlClient=<value>` (and `-p:PackageVersionSqlServer=` where needed) to `build.proj`, which forwards it to the underlying `-p:SqlClientPackageVersion=` / `-p:SqlServerPackageVersion=` project property, hitting Priority 1.
+- Sibling dependencies consumed from pipeline artifacts published by upstream stages.
+
+### CI Pipeline (non-official, triggered on merge)
+
+Same structure as PR but passes `buildSuffix: 'ci'` explicitly.
+
+- **Result:** `7.1.0-preview1-ci.15401` / FileVersion `7.1.0.15401`
+
+### OneBranch Pipeline (official)
+
+**Mode:** Always Package (`ReferenceType=Package`)
+
+Uses the full `compute-versions-stage.yml` machinery:
+
+#### Step A: Compute Versions (dedicated early stage)
+
+1. Runs the `GetVersionsSqlClient` and `GetVersionsSqlServer` MSBuild targets against `build.proj`.
+2. Each target calls `dotnet build <project> -getProperty:<Pkg>PackageVersion` and `-getProperty:<Pkg>FileVersion` with `BuildNumber` but **no BuildSuffix**.
+3. Falls into Priority 2 without BuildSuffix. `NextVersion` already carries a prerelease tag on `main`, so the build number is appended (e.g. `7.1.0-preview1.26238.3`); on a release branch the stable `NextVersion` is used as-is (e.g. `7.1.0`).
+4. `GetVersionsSqlServer` also extracts `SqlServerPublishedVersion` (the SqlClient family has no published version).
+
+#### Step B: Resolve Effective Versions
+
+- The **SqlClient family** always uses `SqlClientNextVersion`.
+- **`Microsoft.SqlServer.Server`** uses its next or published version based on the
+  `buildSqlServer` boolean:
+
+| `buildSqlServer` | Effective SqlServer Version | Meaning |
+|--------------------------|-----------------------------|---------|
+| `True` | `SqlServerNextVersion` (e.g. `1.1.0-preview1`) | SqlServer is being released |
+| `False` | `SqlServerPublishedVersion` (e.g. `1.0.0`) | Only built as a SqlClient dependency; use last-shipped |
+
+> **The default differs by pipeline.** The non-official (nightly) pipeline defaults `buildSqlServer:
+> true`, exercising the "build SqlServer + local-feed dependency" flow; the official pipeline defaults
+> `buildSqlServer: false`, exercising the "depend on the published SqlServer package" flow that
+> matches actual release intent. Either can be overridden at queue time. Requesting `releaseSqlServer`
+> without `buildSqlServer` fails template expansion up front.
+
+These are published as ADO output variables: `versions.SqlClientPackageVersion`,
+`versions.SqlServerPackageVersion`, and their `*FileVersion` counterparts.
+
+#### Step C: Build Stages Consume Pre-computed Versions
+
+Each downstream build job receives:
+- `packageVersion` parameter → passed as `-p:SqlClientPackageVersion=<value>` (or `-p:SqlServerPackageVersion=` for SqlServer)
+- Dependency versions → family dependencies use the shared `SqlClientPackageVersion`; the SqlServer dependency uses `SqlServerPackageVersion`
+
+Since an explicit `<Pkg>PackageVersion` is provided, Versions.props hits Priority 1 — uses the value verbatim.
+
+#### Package Version Shapes
+
+Both OneBranch pipelines use the human-readable run name `$(Year:YY)$(DayOfYear)$(Rev:.r)`, which the
+compute stage receives as `Build.BuildNumber`. That run name drives the single supported package
+version shape: it is appended after any prerelease suffix, reproducing the shape shipped by earlier
+previews.
+
+- `1.2.3` stays `1.2.3` — non-preview releases are never stamped with a build number
+- `1.2.3-preview1` becomes `1.2.3-preview1.<build_number>`, e.g. `7.1.0-preview3.26238.3`
+- The matching file version is `1.2.3.<date_segment>`, e.g. `7.1.0.26238`
+
+Note the asymmetry: the *package* version omits the build number for non-preview releases, but the
+*file* version always carries one in its fourth component. This keeps every shipped assembly
+date-encoded, while preserving the released package version customers expect.
+
+The file version's fourth component is only the *date* segment of the run name, because a four-part
+file version cannot hold the full `<date>.<run>` value. Repeated runs on the same day therefore share
+a file version even though their package versions differ.
+
+Only packages built in the current run are stamped. When `buildSqlServer` is `false`, the effective
+SqlServer version remains `SqlServerPublishedVersion` so dependency restore continues to request the
+package that actually exists on NuGet.
+
+#### Summary
+
+| Package | Version Source | Example |
+|---------|----------------|---------|
+| SqlClient family (always released together) | `SqlClientNextVersion` | `7.1.0-preview1` |
+| SqlServer, being released | `SqlServerNextVersion` | `1.1.0-preview1` |
+| SqlServer, dependency only | `SqlServerPublishedVersion` | `1.0.0` |
+
+## Key Architectural Difference
+
+| Scenario | Who computes versions | How dependencies get versions |
+|----------|----------------------|-------------------------------|
+| Developer | Versions.props inline (Priority 3) | Project references (no version needed) |
+| PR/CI (Project) | `compute-versions-ci-stage` up-front | Project references (no version needed) |
+| PR/CI (Package) | `compute-versions-ci-stage` up-front | Stage variables via `$[ stageDependencies... ]` → `-p:SqlClientPackageVersion=` / `-p:SqlServerPackageVersion=` |
+| OneBranch | `compute-versions-stage` up-front | Explicit `-p:SqlClientPackageVersion=` / `-p:SqlServerPackageVersion=` from stage outputs |
+
+## Updating Versions
+
+After releasing the **SqlClient family**:
+1. Update `SqlClientNextVersion` in `src/Microsoft.Data.SqlClient/Versions.props` to the next planned
+   version.  (There is no family published version to update.)
+
+After releasing **`Microsoft.SqlServer.Server`**:
+1. Update `SqlServerPublishedVersion` to the version just shipped.
+2. Update `SqlServerNextVersion` to the next planned version.
+
+The SqlServer properties live in `src/Microsoft.SqlServer.Server/Versions.props`.

 ## Writing Tests
 
+### Test Documentation Requirements
+
+To keep tests maintainable for contributors and AI agents, test intent must be documented at
+class and method level.
+
+#### Required XML Documentation
+- Add XML `<summary>` comments to every test class.
+- Add XML `<summary>` comments to every test method (`[Fact]`, `[Theory]`, conditional variants).
+- For helper methods used by tests, add XML `<summary>` comments and XML `<param>` / `<returns>`
+  where applicable.
+- For fixture and collection types, add XML `<summary>` comments describing why the fixture exists
+  (for example, serialization of console-mutating tests).
+
+#### What the Comments Must Explain
+- The behavior/contract being tested (not just restating the method name).
+- Why the scenario matters (for example: regression guard, parsing contract, sync/async parity,
+  isolation requirement).
+- For helper methods, what side effects occur (for example console redirection, file system
+  copying, process execution) and why they are needed.
+
+#### Style Guidance
+- Keep comments concise and factual.
+- Prefer behavior-focused wording over implementation trivia.
+- Avoid comments that merely repeat obvious code.
+- Use inline comments inside test methods only for non-obvious setup/act/assert details.
+
+#### Example
+```csharp
+/// <summary>
+/// Ensures malformed connection strings return a non-zero exit code and emit a parse error
+/// without verbose exception details.
+/// </summary>
+[Fact]
+public void AppRunWithMalformedConnectionStringReturnsOneAndWritesParseError()

+### RAII Database Object Classes
+When writing manual integration tests that require transient database objects, use the RAII classes from `Microsoft.Data.SqlClient.Tests.Common.Fixtures.DatabaseObjects` instead of manually writing `try/finally` blocks with DDL `DROP`/`CREATE` statements.
+
+**Available classes:**
+
+| Class | SQL generated | Example definition argument |
+|-------|--------------|----------------------------|
+| `Table` | `CREATE TABLE {Name} {definition}` | `"(Id INT, Value NVARCHAR(100))"` |
+| `StoredProcedure` | `CREATE PROCEDURE {Name} {definition}` | `"AS BEGIN SELECT 1 END"` |
+| `UserDefinedType` | `CREATE TYPE [dbo].{Name} AS {definition}` | `"TABLE (f1 INT)"` |
+
+Each class generates a unique object name from the given prefix (incorporating a timestamp-based GUID, username, and machine name), creates the object on construction (requiring the connection to already be open), and drops it when disposed. The generated name is available via the `.Name` property.
+
+**Pattern:**
+```csharp
+using SqlConnection conn = new(DataTestUtility.TCPConnectionString);
+conn.Open();
+
+using Table testTable = new(conn, "MyTable", "(Id INT, Name NVARCHAR(100))");
+using StoredProcedure proc = new(conn, "MyProc", $"AS BEGIN SELECT * FROM {testTable.Name} END");
+
+using SqlCommand cmd = conn.CreateCommand();
+cmd.CommandText = proc.Name;
+cmd.CommandType = CommandType.StoredProcedure;
+// ... objects are automatically dropped when the scope ends
+```
+
+**Rules:**
+- Open the connection **before** constructing any database object (the constructor executes DDL immediately)
+- When objects depend on each other (e.g., a stored procedure that references a table), declare the dependent object **last** so it is disposed first — `using` declarations are disposed in reverse order
+- Use the `.Name` property directly wherever you need to reference the object in SQL; for `UserDefinedType` this already includes the `[dbo].` schema prefix, making it suitable for use as a TVP `TypeName`

+description: Audit Azure DevOps variable groups by searching repos/branches for usage and updating descriptions accordingly.
+argument-hint: <optional: specific repos, branches, or variable groups to audit>
+tools: ['execute/runInTerminal', 'execute/getTerminalOutput', 'edit/createFile', 'read/readFile']
+---
+
+Audit Azure DevOps variable groups in the **sqlclientdrivers** organization, **ADO.Net** project. Use the `az` CLI where possible; fall back to direct REST API calls where `az` doesn't provide sufficient coverage (e.g., repo file scanning, AzureKeyVault group updates).
+
+## Safety constraints
+
+- **Read-only by default.** Steps 1–4 are purely read-only (listing, searching, summarizing). Do NOT issue any write operations (`PUT`, `PATCH`, `POST`, `az pipelines variable-group update`, or any command that modifies state) until the user has explicitly approved changes in step 5.
+- **No implicit approval.** Silence, ambiguous replies, or partial acknowledgements do NOT count as approval. You must receive an unambiguous "go" (or equivalent affirmative) from the user before proceeding to step 6.
+- **Scope lock.** Only update variable group descriptions. Never delete variable groups, modify variables within a group, or change any pipeline definitions.
+- **Dry-run first.** When presenting the summary in step 4, show the exact before/after description text for every group that would be modified so the user can verify the changes.
+- **Abort on doubt.** If any step produces unexpected errors, ambiguous results, or data that contradicts expectations, stop and ask the user for guidance rather than proceeding.
+
+## Inputs
+
+If the user provided arguments, parse `${input:scope}` for overrides — it may contain specific repos, branches, or variable group names to scope the audit. Apply any recognized values as overrides to the defaults below; ignore unrecognized tokens.
+
+The user may override any of the following defaults:
+
+- **Organization**: `https://sqlclientdrivers.visualstudio.com`
+- **Project**: `ADO.Net`
+- **Repos & branches to search**:
+  - `dotnet-sqlclient`: `internal/main`, `internal/release/7.0`, `internal/release/6.1`
+  - `Microsoft.Data.SqlClient`: `ConfigFuzz`
+  - `Microsoft.Data.SqlClient.Ctaip`: `certAuth`
+  - `Microsoft.Data.SqlClient.sni`: `master`, `release/6.0`
+- **Unused marker text**: `UNUSED - WILL BE DELETED SHORTLY`
+
+## Workflow
+
+### 1. List all variable groups
+
+```
+az pipelines variable-group list --org <ORG> --project <PROJECT> -o json
+```
+
+- Save the output.
+- Identify which groups are already marked with the unused marker text and which are active.
+- Use **fuzzy matching** when detecting the unused marker: check for the presence of both "unused" and "delete" (case-insensitive) in the description, since the actual marker text may vary (e.g. a person's name inserted before "WILL DELETE").
+- In later steps, ignore the current group description when determining usage to avoid biasing the search results.
+
+### 2. Search repos for variable group references
+
+For each repo/branch combination, use the Azure DevOps REST API (Items endpoint) to:
+
+1. List all files recursively in the repo at the given branch.
+2. Filter to `.yml` and `.yaml` files.
+3. Fetch the content of each YAML file.
+4. Search for each variable group name using **exact-match** patterns that prevent prefix false positives (e.g., searching for `Foo` must not match `FooBar`). Match against these forms, ensuring the name is delimited by quotes or end-of-value (whitespace/newline/comment):
+   - `group: '<name>'`  (single-quoted — name bounded by quotes)
+   - `group: "<name>"`  (double-quoted — name bounded by quotes)
+   - `group: <name>` followed by end-of-line, whitespace, or `#` (unquoted — no trailing alphanumeric characters)
+
+Use a Bearer token from `az account get-access-token --resource "499b84ac-1321-427f-aa17-267ca6975798" --query accessToken -o tsv`.
+
+REST API endpoints:
+- **List items**: `{org}/{project}/_apis/git/repositories/{repo}/items?recursionLevel=Full&versionDescriptor.version={branch}&versionDescriptor.versionType=branch&api-version=7.1`
+- **Get file content**: Same endpoint with `path={URL-encoded filePath}&$format=text` (URL-encode the `path` value; use `$format=text` to retrieve raw file content instead of JSON metadata)
+
+Avoid cloning repos. Only use the REST API to fetch file listings and content.
+
+**Performance & rate-limiting guidance**:
+- Filter the file listing to paths likely to contain pipelines (e.g., `eng/`, `pipelines/`, or root-level YAML files) before fetching content, to reduce API calls.
+- Add a short delay (e.g., 200ms) between file-content fetches to avoid hitting Azure DevOps rate limits.
+- If a `429 Too Many Requests` or `503` response is received, back off exponentially (1s, 2s, 4s, …) and retry up to 3 times before logging a warning and moving on.
+
+### 3. Search Classic pipelines for variable group references
+
+Query all **enabled** Classic build and release pipeline definitions for variable group usage.
+
+#### Classic Build pipelines
+
+```
+GET {org}/{project}/_apis/build/definitions?api-version=7.1
+```
+
+- Page through all results (`$top` / `continuationToken` if needed).
+- Keep only definitions where `queueStatus` is **`enabled`**.
+- For each enabled definition, fetch its full JSON:
+  ```
+  GET {org}/{project}/_apis/build/definitions/{id}?api-version=7.1
+  ```
+- Inspect the `variableGroups` array; each element has an `id` that maps to a variable group ID.
+
+#### Classic Release pipelines
+
+The Release API lives on the `vsrm.` sub-domain, but direct REST calls to that sub-domain may fail with SSL certificate errors for `.visualstudio.com` organizations. Use `az devops invoke` instead:
+
+```
+az devops invoke --area release --resource definitions \
+  --org <ORG> --route-parameters project=<PROJECT> \
+  --query-parameters '$expand=environments' '$top=200' \
+  -o json
+```
+
+- Page through results using `continuation_token` if present in the response.
+- Exclude definitions where `isDeleted` is `true`.
+- Each definition can reference variable groups at two levels:
+  - **Definition level**: `variableGroups` array on the root object.
+  - **Stage/environment level**: each element in `environments` has its own `variableGroups` array.
+- Collect all referenced variable group IDs from both levels.
+
+#### Recording results
+
+For every variable group ID found, record:
+- The pipeline **name** and **type** (Build / Release).
+- The stage name (for release-environment-level references).
+
+Merge these results with the repo/branch search results from step 2 so the summary in the next step covers both YAML and Classic usage.
+
+### 4. Summarize findings
+
+Present a clear summary table to the user **before making any changes**. The summary must include:
+
+- **Used groups**: group name, ID, which repos/branches and/or Classic pipelines reference it, and the proposed new description.
+- **Unused groups**: group name, ID, current description, and confirmation it will be marked with the unused marker.
+- **Surprise findings**: any group already marked unused that is actually still referenced (these should be un-marked).
+- **No-change groups**: groups already marked unused and confirmed unused.
+
+### 5. Prompt for go/no-go
+
+**This is a mandatory gate — do NOT skip or auto-approve.**
+
+Ask the user to confirm before applying any changes and require an explicit selection from the options below (do not infer approval from ambiguous replies). Offer options:
+- **Apply all** — apply every proposed change from step 4
+- **Apply subset** — let the user specify which groups to update (by name or ID)
+- **Export script** — write all update commands to a shell script file for the user to inspect and run manually. Do NOT execute any updates. Save the script to a path the user specifies (default: `./audit-variable-group-updates.sh`). The script must include the full `az` CLI commands and REST API `curl` fallbacks (for AzureKeyVault-type groups) with comments identifying each group by name and ID. Mark the file executable.
+- **Abort** — make no changes at all
+
+Do NOT proceed to step 6 unless the user selects "Apply all" or "Apply subset" and, for the subset case, clearly identifies which groups to update. If the user selects "Export script", generate the file and stop — do NOT execute step 6. If the user says "abort" or does not respond, stop here.
+
+### 6. Apply description updates
+
+**Prerequisites**: Step 5 must have completed with explicit user approval. If you have not received approval, do NOT execute this step.
+
+For each group that needs updating, try:
+
+```
+az pipelines variable-group update --group-id <ID> --description "<new description>" --org <ORG> --project <PROJECT> --detect false
+```
+
+**Fallback for AzureKeyVault-type groups**: The `az pipelines variable-group update` command may fail with 500 errors on groups whose `type` is `AzureKeyVault` (it tries to refresh the vault connection). When this happens, fall back to the REST API:
+
+1. `GET {org}/{project}/_apis/distributedtask/variablegroups/{id}?api-version=7.1`
+2. Update **both** the top-level `description` field **and** every entry in `variableGroupProjectReferences[].description` in the JSON.
+3. `PUT` the modified JSON back to the same URL with `Content-Type: application/json`.
+
+**Description rules**:
+- **Used groups**: Prepend `[Used by: <repo>: <branch1>, <branch2>; <repo2>: <branch>; Classic/<type>: <pipeline name>] ` to the existing description (after stripping any previous `[Used by: ...]` prefix). `<type>` is `Build` or `Release`.
+- **Unused groups**: Set description to the unused marker text.
+- **Incorrectly marked unused**: Replace the unused marker with `[Used by: ...]`.
+- **Already correct**: Skip groups whose description would not change.
+
+Report the outcome of each update (success/failure) and a final tally.
+
+## Error handling
+
+- If a repo or branch does not exist or returns an error, log a warning and continue with the remaining repos/branches.
+- If a variable group update fails, log the error and continue with the remaining updates.
+- At the end, report any failures so the user can address them manually.

+## Tool Scoping
+
+Every generated prompt **should** include a `tools` list in its YAML frontmatter. Scoping tools keeps the model focused by limiting it to approved, known-effective tools for the task. Without tool scoping, the model may invoke irrelevant tools, waste context, or produce unpredictable results.
+
+### Why scope tools?
+- **Focus**: Fewer tools means the model spends less reasoning on tool selection and more on the task.
+- **Reliability**: Restricting to tested tools avoids unexpected side effects (e.g., a read-only review prompt shouldn't have edit tools).
+- **Safety**: Prevents prompts from accidentally running terminal commands or making file changes when they shouldn't.
+
+### How to choose tools
+Apply the **principle of least privilege** — include only the tools the prompt actually needs:
+
+| Prompt type | Recommended tools |
+|---|---|
+| **Read-only analysis** (review, triage, explain) | `read/readFile`, `search/codebase`, `search/textSearch` |
+| **Code editing** (bug fix, feature, refactor) | `edit/editFiles`, `edit/createFile`, `read/readFile`, `search/codebase` |
+| **Needs terminal** (build, test, scripts) | All of the above + `execute/runInTerminal`, `execute/getTerminalOutput` |
+| **Needs GitHub data** (triage, release notes) | All of the above + `github/search_issues` or other GitHub tools |
+| **Needs web content** (docs lookup) | `web/fetch` |
+
+### Available built-in tool identifiers
+
+You can specify individual tools or tool sets (which include all tools in that group).
+
+**Tool sets** (use these to include all tools in a category):
+- `edit` — File creation and editing tools

+Generate release notes for the milestone "${input:milestone}" on the branch "${input:branch}".
 
 This repository ships multiple packages. Only generate release notes for packages that have relevant PRs in the milestone. All packages use the same template: [release-notes/template/release-notes-template.md](release-notes/template/release-notes-template.md).
 
+## Branch Model
+
+The release notes content and the source code it describes live on different branches:
+
+- **Release notes files are maintained on `main`.** Every release's notes (for all branches/versions) are committed under `release-notes/` on `main`. Create and edit the release notes Markdown files on `main` (or a PR targeting `main`), not on the release branch.
+- **The source code for the release lives only on the target branch `${input:branch}`.** Version sources (`Versions.props`), project files (`*.csproj`), and dependency files (`Directory.Packages.props`) reflect the released bits *as they exist on `${input:branch}`*, which can differ from `main`. When you look up versions, dependencies, TFM/OS scope, or verify API names (Steps 2.1, 2.2, 4, and the Version and Dependency Lookup table), read those source files from `${input:branch}` — not from your current `main` checkout.
+- **Practical implication:** Do not assume a `...VersionDefault` or dependency version read from `main` matches what shipped on `${input:branch}`. Confirm against `${input:branch}` (e.g., `git show ${input:branch}:<path>`), or against the milestone/release artifacts.

+> **Not all packages exist on every branch.** This table is the full, current package set. Older release branches ship a subset — for example, `release/6.1` and earlier have no extension packages (`Extensions.Abstractions`, `Extensions.Azure`) and no `Internal.Logging`; the companion-package set and even the `AzureKeyVaultProvider` source location vary by branch. Before generating notes for a package, confirm it actually exists on the target branch `${input:branch}` (e.g., `git ls-tree -r --name-only ${input:branch} | grep -i "<package path fragment>"`). Skip any package that does not exist on `${input:branch}`, even if the table lists it.
+
 ## Version and Dependency Lookup
 
-Each package has its own versioning and dependency sources. Use these to determine package versions and dependency lists:
+Each package's version and dependency information comes from MSBuild props/project files **on the target branch `${input:branch}`** (see Branch Model). The exact file paths, file names, and property names that hold versions **differ by branch**, because the versioning layout was refactored over time. Do not assume the layout of your current checkout — discover the version source on `${input:branch}`.
+
+Two known layouts:
+
+| Layout | Branches | MDS version source | Companion/extension version sources |
+| ------ | -------- | ------------------ | ----------------------------------- |
+| **Centralized** | `release/7.0` (and earlier 7.0.x) | `tools/props/Versions.props` (`MdsVersionDefault`) | `tools/props/Versions.props` imports per-package props with the older names: `…/Extensions/Abstractions/src/AbstractionsVersions.props`, `…/Extensions/Azure/src/AzureVersions.props`, `…/Internal/Logging/src/LoggingVersions.props`, `…/Microsoft.Data.SqlClient/add-ons/AzureKeyVaultProvider/AkvProviderVersions.props` |
+| **Per-package** | `main`, `7.1+` | `src/Microsoft.Data.SqlClient/Versions.props` (`SqlClientVersionDefault`) | Each package has its own `Versions.props`: `…/Extensions/Abstractions/src/Versions.props` (`AbstractionsVersionDefault`), `…/Extensions/Azure/src/Versions.props` (`AzureVersionDefault`), `…/Internal/Logging/src/Versions.props` (`LoggingVersionDefault`), `…/AlwaysEncrypted.AzureKeyVaultProvider/src/Versions.props` (`AkvProviderVersionDefault`), `…/Microsoft.SqlServer.Server/Versions.props` (`SqlServerVersionDefault`) |
+
+Discovery approach (works regardless of layout):
 
-| Package | Version Source | Dependency Source |
-|---------|---------------|-------------------|
-| `Microsoft.Data.SqlClient` | [tools/props/Versions.props](tools/props/Versions.props) (`MdsVersionDefault`) | [Directory.Packages.props](Directory.Packages.props) and the [project file](src/Microsoft.Data.SqlClient/src/Microsoft.Data.SqlClient.csproj) |
-| `AzureKeyVaultProvider` | [tools/props/Versions.props](tools/props/Versions.props) (`AkvVersionDefault`) | [AKV project file](src/Microsoft.Data.SqlClient/add-ons/AzureKeyVaultProvider/Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider.csproj) and [Directory.Packages.props](Directory.Packages.props) |

-| `Extensions.Azure` | [AzureVersions.props](src/Microsoft.Data.SqlClient.Extensions/Azure/src/AzureVersions.props) | [Azure.csproj](src/Microsoft.Data.SqlClient.Extensions/Azure/src/Azure.csproj) |

+1. List the version props on the target branch, e.g. `git ls-tree -r --name-only ${input:branch} | grep -i "Versions.props$"`.
+2. Read the relevant file from the target branch, e.g. `git show ${input:branch}:<path>`, and find the package's default/`PackageVersion` property.
+3. Prefer the explicit shipped version: on a release branch the actual version may be supplied by the pipeline (`...PackageVersion`) rather than the `...VersionDefault` fallback, so confirm against the milestone/release artifacts rather than assuming the default.
 
-Concrete dependency versions (e.g., `Azure.Core 1.49.0`) are centrally managed in [Directory.Packages.props](Directory.Packages.props). Framework-conditional versions (e.g., `net9.0` vs everything else) are handled by `Condition` attributes in the same file.
+Dependency sources (read from `${input:branch}`): the per-package project file (`src/Microsoft.Data.SqlClient/src/Microsoft.Data.SqlClient.csproj`, the AKV `.csproj`, `Abstractions.csproj`, `Azure.csproj`, `Logging.csproj`, `Microsoft.SqlServer.Server.csproj`) plus the centrally-managed concrete versions in `Directory.Packages.props`. Framework-conditional versions (e.g., `net9.0` vs everything else) are handled by `Condition` attributes there.
+
+> **Companion package version alignment (7.0.2 and later):** Starting with 7.0.2, the companion packages (`AzureKeyVaultProvider`, `Extensions.Azure`, `Extensions.Abstractions`, `Internal.Logging`) ship version-aligned with the core `Microsoft.Data.SqlClient` driver. When generating notes for an aligned release, use the core MDS version (read from the target branch) for these companion packages — their per-package default version on `main` may point at a different next version and must not be assumed to be the shipped version. `Microsoft.SqlServer.Server` continues to version independently.

+# No `tools:` scoping on purpose: this prompt is access-agnostic and must be able
+# to call whatever Azure DevOps MCP server is connected (e.g. `ado/*`) in addition
+# to the built-in terminal/read/search/edit tools. Declaring a scoped `tools:` list

+---
+
+Triage failing tests in the CI/CD pipelines for commit
+`${input:commit}` and later. Treat only the **first whitespace-delimited token** of
+`${input:commit}` as the target commit SHA — that token is what every git ancestry
+check (`git merge-base --is-ancestor <target> ...`) uses. Any remaining text is
+**optional scope** (e.g. a pipeline name or branch): honor it when present, otherwise
+use the defaults below.
+
+## Azure DevOps access is agnostic
+
+Every data-retrieval step below is described as an **operation**, not a command.
+Perform each operation with whatever Azure DevOps access is available, in this order
+of preference:
+
+1. An **Azure DevOps MCP server**, if one is connected (preferred — no shell needed).
+2. The **`az` CLI** (`az rest --resource <ADO resource ID> ...`,
+   `az pipelines ...`, `az boards ...`).
+3. **Direct ADO REST** calls over HTTPS with a bearer token.
+
+Do not assume a specific mechanism. If the first choice is unavailable or errors,
+fall back to the next. Keep read operations read-only; only edits to test source
+files (quarantine/fix) modify state, and those happen in the repo, not in ADO.
+
+## Environment
+
+- **ADO organization**: `<ADO org>`.
+- **Projects**:
+  - `<CI project>` — CI/PR pipelines target the upstream GitHub repo.
+  - `<mirror project>` — CI/OneBranch pipelines target the ADO mirror repo.
+- The ADO mirror repo preserves the **same commit SHAs** as GitHub, so git
+  ancestry against a GitHub SHA works. It **lags** GitHub because synchronization is
+  gated by PRs: a commit only appears in the mirror once its sync PR completes, so a
+  target commit may not be present in the mirror yet even though it is on GitHub.
+
+## Step 1 — Scope to the right pipelines
+
+**Operation:** list build definitions in both `public` and `ADO.Net`, with each
+definition's folder path, `queueStatus`, and `repository.type` / `repository.name`.
+
+Ignore any definition that is **not currently enabled** (`queueStatus != enabled`,
+i.e. disabled or paused) — also skip names flagged `[Disabled]`, `[Retired]`, or under
+`\Retired\` folders. Then keep only definitions whose repo is the upstream GitHub repo
+or the ADO mirror repo. Exclude legacy driver repos and native SNI repos unless the
+user asks for SNI.
+
+Because this triage targets **non-PR commit runs** (see Step 2), prefer CI/branch
+definitions over PR-validation ones. Prefer CI, package, stress, Kerberos,
+Managed-Instance, and OneBranch official/non-official definitions across both projects.
+PR-triggered definitions are in scope only for the CI/branch runs they may also host —
+their PR-ref runs are excluded in Step 2 unless the user asks to include PR runs.
+
+## Step 2 — Find runs at/after the target commit
+
+**Operation:** for each in-scope definition, list recent runs (filter to
+`failed`, `partiallySucceeded`, `canceled`) with their `sourceBranch`,
+`sourceVersion`, `result`, and `finishTime`.
+
+**Limit to non-PR commit runs.** Only consider runs triggered by real commits on
+tracked branches (e.g. `refs/heads/main`, `refs/heads/release/*`); **exclude PR
+validation runs**. A run is a PR run — and therefore out of scope — when any of these
+hold:
+
+- Its `sourceBranch` is an ephemeral merge ref such as `refs/pull/N/merge` or
+  `refs/pull/N/head`.
+- Its build `reason` is `pullRequest`.
+- It is a PR-triggered definition running against a PR ref.
+
+Keep only runs whose `sourceVersion` is a committed SHA on a tracked branch. If the
+user explicitly asks to include PR runs, honor that override.
+
+Resolve **"at or after `${input:commit}`" by commit graph, not timestamp**:
+
+- `git merge-base --is-ancestor <target> <sourceVersion>` → true means the run's
+  commit is the target or a descendant (in scope).
+- `sourceVersion == <target>` → the target itself (in scope).
+- Divergent `release/*` or `dev/*` commits do **not** descend from a `main` target —
+  exclude them.
+
+Mirror runs use the **same SHAs** as GitHub, so apply the same
+ancestry checks. Because mirror sync is PR-gated, the target commit may not have
+reached the mirror yet — in that window there simply are no in-scope mirror runs, so
+do not infer a run is out of scope from a SHA mismatch (there is none); it is only a
+timing lag.
+
+## Step 3 — Enumerate failing test runs per build
+
+**Operation:** for each in-scope build, list its test runs.
+
+Compute real failures as `totalTests - passedTests - notApplicableTests`. Do **not**
+treat `unanalyzedTests`/`notApplicableTests` as failures. Keep runs with failures > 0.
+
+## Step 4 — Get failing test names and errors
+
+**Operation:** for each failing test run, fetch the `Failed` results with their
+`automatedTestName`, `errorMessage`, and `stackTrace`.
+
+**You must capture the actual xUnit output and full stack trace for every failed
+test — do not classify a failure without it.** The one-line `errorMessage` is not
+enough; get the complete assertion text (e.g. `Assert.Equal() Failure: Values differ /
+Expected / Actual`) and the full stack frames (the test method and the failing product
+frames). If any source truncates it, cross-check another until you have the whole thing:
+
+- The result's `errorMessage` + `stackTrace` fields (expand sub-results — see below).
+- The test run's **attachments** (TRX / `*.trx`, console logs) when the API truncates
+  long stacks.
+- The **job log** for the test step (Step 5) — the raw `dotnet test` / xUnit output
+  always contains the assertion and stack, even when the results API does not.
+
+**CRITICAL — data-driven (Theory) results hide the error on a child:** xUnit
+`[Theory]`/`[ClassData]`/`[InlineData]` tests publish as a parent result with
+`resultGroupType == "dataDriven"` whose own `errorMessage`/`stackTrace` are **null**.
+The real assertion lives on the failing **sub-result**. When a `Failed` result has a
+null error, re-fetch that result **including sub-results** and read the child. A null
+parent error means "look at the children", not "the test aborted". Only treat it as an
+abort when the build log also shows no assertion and the process was terminated
+(e.g. a `--blame-hang` dump).
+
+## Step 5 — Locate each failure's job (for logs/links)
+
+**Operation:** for a failing run, read its `pipelineReference` (stage/phase/job), then
+read the build's timeline and walk Stage → Phase → Job by `parentId` to get the job
+record id. Build deep links:
+
+- Tests tab: `.../_build/results?buildId=<id>&view=ms.vss-test-web.build-test-results-tab`
+- A specific result: append `&runId=<runId>&resultId=<resultId>&paneView=debug`
+- Job logs: `.../_build/results?buildId=<id>&view=logs&j=<jobRecordId>`
+
+## Step 6 — Classify every failure
+
+| Class | Signals | Action |
+|-------|---------|--------|
+| **True positive** (broken driver) | Deterministic; fails on every leg for the commit; assertion tied to changed code; absent on the parent commit | Fix the bug; keep/add a failing test |
+| **Test-isolation / concurrency** | Off-by-a-small-count on a process-global resource (e.g. pool `ConnectionCount` Expected 2 Actual 3); some data rows pass, others fail; depends on parallel tests | Isolate the resource (unique connection string, `[Collection]`); else quarantine |
+| **Flaky (timing/GC/load)** | Intermittent; only under CI load; GC-finalizer or retry/failover timing; "connection is broken" under contention | Deterministic fix (poll not sleep, set retry interval/timeouts); else quarantine |
+| **Environmental / infra** | Empty error AND no assertion in the log; host/agent crash; blame-hang dump; network/DTC outage; many unrelated tests fail at once | Re-run to confirm; report infra; don't quarantine on a single infra hit |
+
+Determine **regression vs pre-existing** by repeating Steps 3–4 on the
+immediately-preceding in-scope build (the parent commit). A failure present before
+`${input:commit}` was not introduced by it.
+
+## Step 7 — Check quarantine status before acting
+
+A test is already quarantined if it carries `[Trait("category", "flaky")]`; those run
+in a separate, non-blocking quarantine step (`TestFilters="category=flaky"`) while the
+regular step excludes `category!=failing&category!=flaky&category!=interactive`.
+
+- Already-quarantined failure = expected quarantine noise, not a blocker. Only escalate
+  with a real fix.
+- Non-quarantined failure in a regular step = a real blocker.
+
+## Step 8 — Present findings and STOP (checkpoint)
+
+Steps 1–7 are **read-only investigation**. Before changing anything, present your
+findings and wait for the user's explicit go-ahead. Do **not** edit any files or take
+any action until the user approves.
+
+Present a per-failure table: test name, in-scope build(s), full xUnit assertion +
+key stack frames, classification, whether it is a regression, current quarantine
+status, and the **proposed** action (fix / quarantine / already quarantined /
+re-run to confirm). Link each failure to its build/result and job. Then explicitly ask
+the user which items to act on.
+
+## Step 9 — Act (only after approval)
+
+For each item the user approves:
+
+1. Prefer a **deterministic fix** that removes the race/isolation/timing dependency.
+2. Otherwise **quarantine**: add `[Trait("category", "flaky")]` plus a comment holding
+   the observed failure signature (test name, assertion, key stack frames) and the
+   root-cause reasoning. Mirror the style of existing quarantine comments in the test suite.
+3. Cover both sync and async variants when the API has both.
+4. Un-quarantine once fixed and consistently green.
+
+Make only the source edits needed to fix or quarantine; do not modify pipeline YAML or
+ADO state. After editing, report what changed.

+# OVERVIEW
+# --------
+# Milestones in this repository are named "<major>.<minor>.<patch>", optionally
+# with a pre-release suffix (e.g. "7.0.3", "8.0.0-preview1"). Every milestone
+# therefore maps to a candidate release branch:
+#
+#     <major>.<minor>.<patch>  ->  release/<major>.<minor>
+#
+# Release branches and configured milestones determine where the work belongs:
+#
+#   * The branch EXISTS  -> that version has already forked off the default
+#     branch and is in servicing. Changes for it go to release/<major>.<minor>.
+#
+#   * The branch DOES NOT exist, and this is the earliest configured milestone
+#     series without a release branch -> that version is in development on the
+#     default branch. Changes for it go to the default branch.
+#
+#   * Any other series -> the default branch carries exactly one development
+#     line, so a later series is not active yet and an earlier series is no
+#     longer in development. Neither may target the default branch.
+#
+# This rule is self-maintaining: no hard-coded version list needs updating when
+# a new release branch is cut.

+# cherry-pick-to-release.sh
+#
+# Cherry-picks a merge commit from the default branch onto a release branch
+# and opens a pull request for the result. If the cherry-pick conflicts, an
+# empty-commit placeholder PR is created with manual resolution instructions.
+#
+# OVERVIEW
+# --------
+# This script performs the following steps:
+#
+#   1. Derive the target release branch from the version's major.minor
+#      (e.g. "7.0.1" → release/7.0).
+#
+#   2. Check whether the commit's patch is already present on the target
+#      branch (via 'git cherry'). If so, exit cleanly — nothing to do.
+#
+#   3. Detect whether the merge commit is a true merge (2+ parents) or a
+#      squash-merge (1 parent).  True merges require '--mainline 1'.
+#
+#   4. Attempt the cherry-pick:
+#      - On success: push the branch, look up the milestone, create a PR.
+#      - On conflict: abort, push an empty-commit placeholder, create a
+#        "CONFLICTS" PR with manual resolution instructions.
+#
+#   5. Milestone lookup is best-effort. If the milestone doesn't exist yet
+#      the PR is created without one and a warning note is added to the body.
+#
+# REQUIRED ENVIRONMENT VARIABLES
+# ------------------------------
+#   VERSION            Full hotfix version, e.g. "7.0.1".
+#   MERGE_COMMIT_SHA   SHA of the merge commit on the default branch.
+#   PR_NUMBER          Number of the original PR that was merged.
+#   PR_TITLE           Title of the original PR (used in cherry-pick PR title).
+#   GH_TOKEN           GitHub token for 'gh' CLI authentication.
+#   GITHUB_REPOSITORY  Owner/repo (e.g. "dotnet/SqlClient"). Set by Actions.
+#
+# OUTPUTS
+# -------
+#   On success or conflict, a new PR is created on GitHub.
+#   On already-applied, the script exits 0 with a notice.
+#
+# USAGE
+#   Typically called from the cherry-pick-hotfix.yml workflow.
+#   The git working directory must have full history (fetch-depth: 0) and
+#   user.name / user.email must be configured before calling this script.
+#
+#   Local testing example (dry-run — comment out 'gh pr create' calls):
+#
+#     export VERSION="7.0.1"
+#     export MERGE_COMMIT_SHA="abc123"
+#     export PR_NUMBER=42

+# Parses "Hotfix X.Y.Z" labels from a merged GitHub PR and emits a JSON array
+# of version strings suitable for use as a GitHub Actions matrix dimension.
+#
+# OVERVIEW
+# --------
+# This script handles two distinct trigger scenarios:
+#
+#   1. 'closed' event  — The PR was just merged. ALL "Hotfix X.Y.Z" labels on
+#      the PR are processed, emitting one version per valid label.
+#
+#   2. 'labeled' event — A label was added to an already-merged PR. Only the
+#      NEWLY ADDED label is considered, and only if a cherry-pick for that
+#      version hasn't already been created (branch or PR exists).
+#
+# Label names must match the exact pattern "Hotfix <major>.<minor>.<patch>"
+# (e.g. "Hotfix 7.0.1"). All other labels are silently ignored.
+#
+# REQUIRED ENVIRONMENT VARIABLES
+# ------------------------------
+#   LABELS             Comma-separated list of all label names on the PR.
+#   EVENT_ACTION       The GitHub event action: "closed" or "labeled".
+#   EVENT_LABEL        For 'labeled' events, the name of the label that was added.
+#                      Empty or unset for 'closed' events.
+#   PR_NUMBER          The pull request number (used to derive cherry-pick branch names).
+#   GH_TOKEN           GitHub token for API calls (gh CLI auth).
+#   GITHUB_REPOSITORY  Owner/repo (e.g. "dotnet/SqlClient"). Set automatically by Actions.
+#
+# OUTPUTS
+# -------
+#   Writes to $GITHUB_OUTPUT:
+#     versions=<JSON array>   e.g. versions=["7.0.1","8.0.0"]
+#
+#   An empty array (versions=[]) means no work is needed.
+#   The script exits with code 1 if the 'closed' event has no valid labels.
+#
+# USAGE
+#   Called from the cherry-pick-hotfix.yml workflow. Can also be run locally
+#   for testing by setting the required environment variables and providing a
+#   writable GITHUB_OUTPUT file:
+#
+#     export LABELS="Hotfix 7.0.1,bug"
+#     export EVENT_ACTION="closed"

+# recheck-milestones-for-release-branch.sh
+#
+# Re-runs the milestone check for open pull requests whose result can change
+# when a release branch is created.
+#
+# OVERVIEW
+# --------
+# check-milestone-branch.sh decides where a milestone belongs by asking whether
+# release/<major>.<minor> exists and which configured milestone series is the
+# earliest one without a release branch. Cutting a branch therefore moves its
+# X.Y.* milestones into servicing and can make the next series active.
+#
+# Creating a branch emits no pull request activity, so an already-open PR keeps
+# whatever result it last recorded. This script closes that gap by re-running
+# every semantic-version-milestoned PR targeting the default branch. That covers
+# both the newly serviced series and any later series whose eligibility changes.
+#
+# Re-running is enough because check-milestone-branch.sh queries the live list
+# of release branches. The replayed event payload still carries the correct
+# milestone and base branch, since the check re-runs on every 'milestoned' and
+# 'edited' activity, so the newest run always reflects the current PR state.
+#
+# LIMITATION
+# ----------
+# A re-run replays the original run's commit, which means it executes the
+# workflow definition and script as they existed then. Only the release branch
+# lookup is evaluated live.
+#
+# So a pull request whose most recent milestone check predates the arrival of
+# the target-branch rule will replay the older check, pass it, and keep its
+# stale result. This is transitional: any pull request with activity after the
+# rule shipped has a run that contains it. It is not detected here, because
+# distinguishing a stale replay costs an extra API call per pull request and
+# the window closes on its own. After the first release branch is cut following
+# a change to the check itself, review the affected pull requests by hand.
+#
+# REQUIRED ENVIRONMENT VARIABLES
+# ------------------------------
+#   RELEASE_BRANCH     The branch that was just created (e.g. "release/7.1").
+#   DEFAULT_BRANCH     The repository's default branch (e.g. "main").
+#   WORKFLOW_FILE      Workflow file name to re-run (e.g. "check-milestone.yml").
+#   GITHUB_REPOSITORY  Owner/repo (e.g. "dotnet/SqlClient"). Set automatically by Actions.
+#   GH_TOKEN           GitHub token for API calls. Needs 'actions: write'.
+#
+# OUTPUTS
+# -------
+#   Emits ::notice:: per PR re-run and ::warning:: for any PR that could not be
+#   re-run. Exits 1 if at least one re-run failed, so the failure is visible in
+#   the Actions UI; a maintainer can then re-run those checks by hand.
+#
+# USAGE
+#   Called from the recheck-milestones.yml workflow. Can also be run locally:
+#
+#     export RELEASE_BRANCH="release/7.1"
+#     export DEFAULT_BRANCH="main"
+#     export WORKFLOW_FILE="check-milestone.yml"
+#     export GITHUB_REPOSITORY="dotnet/SqlClient"
+#     bash .github/scripts/recheck-milestones-for-release-branch.sh

+# the rest. Failures are tracked explicitly and reported at the end.

+# GitHub Actions Script Tests
+
+This directory contains tests for the shell scripts used by the
+[cherry-pick-hotfix](./../../../.github/workflows/cherry-pick-hotfix.yml),
+[check-milestone](./../../../.github/workflows/check-milestone.yml) and
+[recheck-milestones](./../../../.github/workflows/recheck-milestones.yml) GitHub Actions workflows.
+These tests are intended to be run manually by developers when they are changing the associated
+scripts, and not as part of any CI runs.
+
+## What is Bats?
+
+**[Bats](https://github.com/bats-core/bats-core)** (Bash Automated Testing System) is a
+TAP-compliant testing framework for Bash scripts. Each `.bats` file contains one or more `@test`
+blocks that run shell commands and assert outcomes using the built-in `run` helper. A test passes
+when every command exits with code 0; it fails on the first non-zero exit.
+
+Key concepts:
+
+| Concept | Description |
+| ------- | ----------- |
+| `@test "name" { ... }` | Defines a single test case |
+| `run <command>` | Captures stdout, stderr, and exit code into `$output` and `$status` |
+| `setup()` | Runs before every `@test` — used to create temp files and set env vars |
+| `teardown()` | Runs after every `@test` — used to clean up temp files |
+| `[[ "$status" -eq 0 ]]` | Assert exit code |
+| `[[ "$output" == *"text"* ]]` | Assert output contains a string |
+
+## Installing Bats
+
+### Linux (apt)
+
+```bash
+sudo apt-get update && sudo apt-get install -y bats
+```
+
+### macOS (Homebrew)
+
+```bash
+brew install bats-core
+```
+
+### From source (any platform)
+
+```bash
+git clone https://github.com/bats-core/bats-core.git
+cd bats-core
+sudo ./install.sh /usr/local
+```
+
+## Additional Prerequisites
+
+The scripts under test also require:
+
+- **jq** — used to build JSON matrix output
+- **gh** (GitHub CLI) — used for API calls and PR creation (mocked during tests, but must be on
+  `$PATH` for the test stubs to shadow it)
+
+Most CI runners and development machines have these pre-installed. If not:
+
+```bash
+# Linux (apt)
+sudo apt-get install -y jq gh
+
+# macOS (Homebrew)
+brew install jq gh
+```
+
+### Verify installation
+
+```bash
+bats --version
+# Expected output: Bats 1.x.x
+```
+
+## Running the Tests
+
+All commands assume you are at the **repository root**.
+
+### Run all tests
+
+```bash
+bats .github/scripts/tests/
+```
+
+### Run a single test file
+
+```bash
+bats .github/scripts/tests/extract-hotfix-versions.bats
+bats .github/scripts/tests/cherry-pick-to-release.bats
+bats .github/scripts/tests/check-milestone-branch.bats
+bats .github/scripts/tests/recheck-milestones-for-release-branch.bats
+```
+
+### Run a specific test by name
+
+```bash
+bats .github/scripts/tests/extract-hotfix-versions.bats \
+  --filter "single Hotfix label"
+```
+
+### Verbose output (show each test name)
+
+```bash
+bats --tap .github/scripts/tests/
+```
+
+### Pretty output (requires bats-core 1.5+)
+
+```bash
+bats --formatter pretty .github/scripts/tests/
+```
+
+## Test Files
+
+| File | Tests | Covers |
+| ---- | ----- | ------ |
+| `extract-hotfix-versions.bats` | 18 | Label parsing, version extraction, matrix JSON output, edge cases (malformed labels, duplicates, `labeled` vs `closed` events) |
+| `cherry-pick-to-release.bats` | 15 | Branch derivation, already-applied detection, clean cherry-pick, conflict handling, milestone lookup, PR creation, duplicate skip logic |
+| `check-milestone-branch.bats` | 26 | Milestone version parsing, state-independent active development-line selection, rejection of earlier and later series on the default branch, fail-closed handling when no series is active, release-branch derivation, default-branch vs release-branch validation, integration-branch and non-semver skips, API invocation assertions, API failure handling |
+| `recheck-milestones-for-release-branch.bats` | 17 | Release-branch name parsing, matching open PRs by milestone, run lookup by head SHA and PR association, fork fallback, re-run invocation, and failure reporting |
+
+## How the Tests Work
+
+All test files use the same general approach:
+
+1. **`setup()`** creates a temporary directory and populates it with mock `git` and `gh` executables
+   — simple shell scripts that echo predetermined responses. Environment variables (`VERSION`,
+   `MERGE_COMMIT_SHA`, etc.) are set to known values.
+
+2. **`@test` blocks** call `run bash "$SCRIPT"` to execute the script under test in a subshell. The
+   mocks intercept all `git` and `gh` invocations, so no real repository or GitHub API access is
+   needed.
+
+3. **Assertions** check `$status` (exit code) and `$output` (combined stdout/stderr) for expected
+   values, error messages, GitHub Actions output file writes via `$GITHUB_OUTPUT`, or other
+   workflow commands such as `::error::` and `::notice::`.
+
+4. **`teardown()`** removes the temporary directory and mock binaries.
+
+### Example mock
+
+```bash
+# Mock git that reports 2 parents (a merge commit)
+cat > "${STUB_DIR}/git" <<'MOCK'
+#!/usr/bin/env bash
+case "$*" in
+  "rev-list --parents -n1 "*) echo "abc123 parent1 parent2" ;;
+  "cherry "*)                 echo "+ abc123" ;;
+  *)                          echo "git mock: $*" ;;
+esac
+MOCK
+chmod +x "${STUB_DIR}/git"
+```
+
+The mock sits earlier on `$PATH` than the real `git`, so the script under test calls the mock
+transparently.
+
+## Troubleshooting
+
+### `bats: command not found`
+
+Bats is not installed. See [Installing Bats](#installing-bats) above.
+
+### Tests fail with `permission denied`
+
+The scripts under `.github/scripts/` must be executable:
+
+```bash
+chmod +x .github/scripts/*.sh
+```
+
+### A test fails unexpectedly
+
+Run with `set -x` tracing to see each command:
+
+```bash
+bats --tap .github/scripts/tests/cherry-pick-to-release.bats \
+  --filter "name of failing test" 2>&1
+```
+
+Or add `echo "DEBUG: $variable" >&3` inside a test to print to the terminal (file descriptor 3 is
+bats's "direct to terminal" channel).

+# Agentic Workflows Router
+
+Use this skill when a user asks to design, create, update, debug, or upgrade GitHub Agentic Workflows in this repository.
+
+This skill is a dispatcher: identify the task type, load the matching workflow prompt/skill file, and follow it directly. Keep responses concise and ask a clarifying question if the correct prompt is unclear.
+
+Read only the files you need:
+Load these files from `github/gh-aw` (they are not available locally).

+#      PR prefixed with "[<version> Cherry-pick]".

+
+# SqlClient Issue Auto-Triage
+
+You are a triage specialist for **Microsoft.Data.SqlClient**.
+Your job is to post **at most one** triage summary comment per workflow run
+using `add_comment`.
+
+This workflow runs in three situations. Identify which one **before** doing
+any work, then follow the matching flow:
+
+1. **Initial triage** — `event_name == "issues"`. A new issue was just opened.
+   Always proceed to the triage instructions below.
+2. **Follow-up triage** — `event_name == "issue_comment"` and the comment body
+   does NOT start with `/triage`. The workflow-level `if:` has already verified
+   the issue currently carries the label `Auto-Triage: Waiting for Author`,
+   so a prior triage flagged missing env info and the author has now responded.
+   Treat later author comments as part of the issue body and re-validate the
+   environment. There are three sub-cases routed by "Follow-up routing" under
+   Instructions:
+   - **No progress** (comment supplied no new env field, e.g. "will share
+     soon") → silent `noop`, label stays, no comment posted.
+   - **Partial progress** (comment supplied at least one new env field but
+     others are still missing) → post a fresh summary acknowledging what
+     was provided and re-asking for the rest, KEEP the label.
+   - **Complete** (all required env fields are now present) → post a fresh
+     summary, REMOVE the label.
+3. **On-demand triage** — `event_name == "issue_comment"` and the comment body
+   starts with `/triage`. A maintainer is explicitly requesting a fresh triage.
+   Ignore label state and prior summary counts; proceed to the triage
+   instructions and produce a new summary. Do NOT change the label as part of
+   `/triage` runs (leave it as-is).
+
+Do NOT call `add_comment` more than once per run.
+Do NOT call `add_labels` or `remove_labels` for any label other than
+`Auto-Triage: Waiting for Author` — that single label is the only one this
+workflow is permitted to manage.
+Do NOT post intermediate findings. Do NOT post separate comments for
+area detection, duplicate checking, or environment validation.
+Everything goes into the single triage summary at the end.
+
+---
+
+## Label-managed state
+
+The workflow uses one internal-state label to decide cheaply (at the YAML
+`if:` level) whether an author comment should boot the agent at all:
+
+- **`Auto-Triage: Waiting for Author`** — present iff the most recent
+  triage summary flagged `⚠️ Missing:` or `⚠️ Partial:` environment fields
+  and we are waiting for the issue author to supply them.
+
+The agent (you) is responsible for keeping this label accurate — see the
+"Actions" section below for exactly when to call `add_labels` /
+`remove_labels`.
+
+Only if the workflow-level `if:` gate above evaluated to true, proceed to the
+triage instructions below and produce a fresh summary. Treat the prior summary
+as **invalidated** — the new one supersedes it (the older one will be collapsed
+automatically by `hide-older-comments`).
+
+---
+
+## Required Context
+
+Before analyzing the issue, you MUST read all project knowledge base files
+from the checked-out repository. Recursively list the `.github/` directory
+and read every markdown file (`.md`) found under it, excluding the `workflows/`
+subdirectory. This includes but is not limited to instructions, prompts,
+issue templates, skills, plans, and any other documentation files present.
+
+Use these files to inform your area classification, duplicate detection,
+environment validation, and analysis. Do not skip this step.
+
+---
+
+## Instructions
+
+Read the issue body **and, for follow-up / on-demand runs, every subsequent
+comment**. Then do ALL of the following analysis silently (using read tools
+and search only — no comments, no outputs):
+
+### Follow-up routing (scenario 2 only)
+
+Before running the full analysis on a follow-up run, decide which of three
+sub-cases this comment falls into. Use the rules in step **B** below to
+determine which environment fields each source supplies.
+
+Compute two snapshots:
+
+- **BEFORE** = env fields supplied by the issue body + every author comment
+  EXCEPT the triggering comment.
+- **AFTER**  = env fields supplied by the issue body + every author comment
+  INCLUDING the triggering comment.
+
+Then route as follows:
+
+1. **No progress** — `AFTER == BEFORE` (the new comment did not supply any
+   new env field; e.g. "okay, will share details soon", a question, an
+   unrelated remark). → Call `noop` with a short reason like `"Author
+   commented but supplied no new env info"` and STOP. Do NOT call
+   `add_comment`. Do NOT change the label. The label stays so the next
+   author comment can re-trigger this workflow.
+
+2. **Partial progress** — `AFTER` adds at least one new env field but is
+   still incomplete (some required fields are still missing). → Proceed
+   to the full analysis below and post a fresh triage summary. The
+   `Environment` row MUST acknowledge what was just provided and list
+   only the fields that are STILL missing, e.g.
+   `⚠️ Partial: received SqlClient version and OS; still missing: .NET TFM, SQL Server version`.
+   Keep the label `Auto-Triage: Waiting for Author` on the issue (i.e. call
+   `add_labels` with that label — it is a no-op if already present).
+
+3. **Complete** — `AFTER` contains every required env field. → Proceed to
+   the full analysis below and post a fresh triage summary. The
+   `Environment` row says `All required environment details provided for
+   investigation`. Call `remove_labels` with the label.
+
+This routing does NOT apply to initial triage (scenario 1) or on-demand
+`/triage` (scenario 3) — those always produce a fresh summary using the
+standard label-management rules in the Actions section below.
+
+### Full analysis
+
+**A. Classify issue type**: Bug (reports unexpected behavior, crash, regression, or incorrect results), Feature (has proposal), Question, or Task.
+
+**B. Validate environment** (bugs only): Check for these required fields:
+SqlClient version, .NET target framework, SQL Server version, OS,
+repro steps, expected vs actual behavior.
+If any are missing, list them explicitly in the triage summary (e.g. "Missing: SQL Server version, OS").
+For follow-up runs, treat information supplied in any later comment by the
+issue author as if it were part of the original issue body.
+Proceed with all remaining triage steps regardless of missing environment details.
+
+**C. Classify area**: Based on the issue content, pick the single best matching area label from this list:
+
+| Label | Scope |
+|-------|-------|
+| `Area\Connection Pooling` | Pool behavior, timeouts, pool size, pool exhaustion |
+| `Area\AKV Provider` | Always Encrypted Azure Key Vault provider |
+| `Area\Json` | JSON data type support |
+| `Area\Managed SNI` | Managed SNI / network layer |
+| `Area\Native SNI` | Native SNI / network layer |
+| `Area\Sql Bulk Copy` | SqlBulkCopy operations |
+| `Area\Netcore` | .NET runtime / netcore specific |
+| `Area\Netfx` | .NET Framework specific |
+| `Area\Tests` | Test code / test projects |
+| `Area\Documentation` | Docs and samples |
+| `Area\Azure Connectivity` | Azure connectivity |
+| `Area\Engineering` | Build, CI/CD, infrastructure |
+| `Area\Vector` | Vector feature |
+| `Area\Async` | Async operations |
+
+**D. Search for duplicates**: Search `repo:dotnet/SqlClient <key terms>` for similar issues.
+
+**E. Check for regression**: If the reporter mentions a previously working version, note the version boundary.
+
+---
+
+## Actions
+
+Call `add_comment` exactly **once** with this markdown. For follow-up runs
+add "(updated after author response)" to the heading; for on-demand `/triage`
+runs add "(on-demand re-triage)" to the heading:
+
+```
+## 🔍 Triage Summary
+
+| Check | Result |
+|-------|--------|
+| Issue type | <Bug / Feature / Question / Task> |
+| Environment | <All required environment details provided for investigation / ⚠️ Partial: received <list>; still missing: <list> / ⚠️ Missing: list specific fields> |
+| Area | <Best matching area from classification table> |
+| Duplicates | <None found / Potentially related: #NNN, #NNN> |
+| Regression | <Not indicated / Likely regression from vX.Y.Z / Inconclusive> |
+
+### Analysis
+
+<2-4 sentences: what the issue is about, which component is likely affected,
+and severity assessment (P0-P3)>
+
+### Next Steps
+
+<Actionable items. Be specific, not vague.
+- If environment details are missing: explicitly ask the author to provide the
+  specific missing fields (e.g. "@author, please provide: .NET target framework,
+  SQL Server version, and Operating system so we can proceed with investigation.")
+- If environment is complete and this is a confirmed bug: state that assign this issue to Copilot coding agent to investigate, AND include specific
+  investigation guidance based on the analysis (e.g. "Assign to Copilot coding
+  agent to investigate SqlDataReader.GetFieldValueAsync and related async internals
+  to apply the same Nullable<T> handling logic present in the synchronous path.")
+- If duplicates were found: recommend reviewing the linked issues before proceeding.
+- If regression: note the version boundary and state that bisection is recommended.>
+
+> **Note**: This triage summary is auto-generated by an AI agent. The analysis and suggestions above have not been verified by a human maintainer. Please treat as preliminary guidance only.
+```
+
+**Then manage the label**:
+
+- For **on-demand `/triage` runs**, do NOT touch the label — preserve
+  whatever state existed before.
+- For **initial triage** and **follow-up triage**, base the decision on the
+  `Environment` row of the summary you just posted:
+  - If it contains `⚠️ Missing:` or `⚠️ Partial:` → call `add_labels` with
+    `["Auto-Triage: Waiting for Author"]` (no-op if already present).
+  - Otherwise (env complete) → call `remove_labels` with
+    `["Auto-Triage: Waiting for Author"]` (safe to call even if absent).
+
+If the issue is spam or no action is needed, call the `noop` tool instead.

 6. **Performance Optimization**: Use pooling, async, efficient allocations
 7. **Observability**: EventSource tracing, meaningful errors
 
+## Terminal Reliability Rules
+
+When using shell/terminal tools, follow these rules strictly:
+
+1. Treat non-zero terminal exit codes as immediate failures to investigate; do not continue as if the command succeeded.
+2. If a bash session exits, assume it is dead and start a new command/session; do not wait for additional output from that session.
+3. After any command expected to gather data, verify output was actually returned before proceeding.
+4. If command execution failed, report the failure clearly and retry with a corrected command instead of waiting.
+5. Avoid `set -e` in this automation context; prefer single-purpose commands with explicit follow-up checks so failures are visible without killing the shell unexpectedly.
+6. Prefer shorter command batches over long chained scripts when collecting evidence; this makes bash exits easier to detect and recover from.
+
+## Branch Naming
+
+All branches created by AI agents **must** live under the `dev/automation/` prefix. Use a descriptive suffix, for example:
+
+- `dev/automation/fix-connection-timeout`
+- `dev/automation/add-json-type-tests`
+
+Do **not** create branches directly under `main`, `dev/`, or any other top-level prefix.

 ## Prerequisites
 
 ### .NET SDK
 
-The projects in this repo require the .NET 10.0 SDK to build.  Please ensure you
-have the latest version of that SDK installed.
-
-Tests and tools may require different .NET Runtimes that may be installed
-independently.  For example, tests targeting .NET 8.0 will need that runtime
-installed.
-
-### Visual Studio
-
-This project should be built with Visual Studio 2019+ for the best compatibility. The required set of components are provided in the below file:
-
-- **Visual Studio 2019** with imported components: [VS19Components](/tools/vsconfig/VS19Components.vsconfig)
-
-- **Powershell**: To build SqlClient on Linux, powershell is needed as well. Follow the distro specific instructions at [Install Powershell on Linux](https://learn.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-linux?view=powershell-7.4)
-
-Once the environment is setup properly, execute the desired set of commands below from the _root_ folder to perform the respective operations:
-
-### Manual Test Prerequisites
-
-Manual Tests require the below setup to run:
-
-- SQL Server with enabled Shared Memory, TCP and Named Pipes Protocols and access to the Client OS.
-- Databases "NORTHWIND" and "UdtTestDb" present in SQL Server, created using SQL scripts [createNorthwindDb.sql](tools/testsql/createNorthwindDb.sql) and [createUdtTestDb.sql](tools/testsql/createUdtTestDb.sql). To setup an Azure Database with "NORTHWIND" tables, use SQL Script: [createNorthwindAzureDb.sql](tools/testsql/createNorthwindAzureDb.sql).
-- Make a copy of the configuration file [config.default.json](src/Microsoft.Data.SqlClient/tests/tools/Microsoft.Data.SqlClient.TestUtilities/config.default.json) and rename it to `config.json`. Update the values in `config.json`:

-## Example Commands to Run Tests Using MSBuild (Recommended)
-
-Using the default configuration and running all tests:
+Projects in this repository require the .NET SDK to be installed in order to build. For the exact version required for
+building the current version, see [global.json](global.json). Downloads for .NET SDK can be found at
+[.NET Downloads](https://dotnet.microsoft.com/en-us/download/dotnet).
+
+The .NET SDK contains support for building for previous versions of .NET, including support for building .NET Framework
+on operating systems that do not support .NET Framework. As such, it is not necessary to install any version of the
+.NET SDK aside from the version specified in [global.json](global.json).
+
+### Miscellaneous
+
+**PowerShell** is included as a .NET local tool in this repository. Running `dotnet tool restore`
+(see below) will make it available via `dotnet tool run pwsh -- <args>`. Note that `pwsh` is not
+added to PATH — it must be invoked through `dotnet tool run`. Build targets handle this
+automatically; manual invocation is only needed for ad-hoc scripting.
+
+The **NuGet** binary is optional for inspection and feed-management workflows, but build and packaging flows in this
+repository are run through `dotnet build` against `build.proj`.
+
+### .NET Tools
+
+This repository uses .NET local tools (e.g. PowerShell) that must be restored before building. Run the following from the repository root:
 
 ```bash
-msbuild -t:RunTests
+dotnet tool restore
 ```
 
-Using the Release configuration:
+## Developer Workflow
+
+Once you've cloned the repository and made your changes to the codebase, it is time to build, test, and optionally
+package the project. The `build.proj` file provides convenient targets to accomplish these tasks.
+
+> [!NOTE]
+> Although every effort has been made to make building and testing work in your IDE of choice, some quirks in behavior
+> may be noticed, possibly severe. All official build and test infrastructure uses the `build.proj` entrypoint, and it
+> is recommended that `build.proj` is used for local development, as well.
+
+<!-- Avoid MD028 (blank line inside a blockquote - these are 2 separate blockquotes. -->
+
+> [!TIP]
+> This section is not exhaustive of all targets or parameters to `build.proj`. Complete documentation is available in
+> [`build.proj`](build.proj).
+
+### Building Projects
+
+From the root of your repository, run `dotnet build` against `build.proj` with a build target, following this pattern:
 
 ```bash
-msbuild -t:RunTests -p:Configuration=Release
+dotnet build build.proj -t:<build_target> [optional_parameters]
 ```
 
-Running only the unit tests:
+Since `build.proj` is the only project file in the repo root, it can be omitted when building from
+the root:
 
 ```bash
-msbuild -t:RunUnitTests
+dotnet build -t:<build_target> [optional_parameters]
 ```
 
-Using a specific .NET runtime to run tests:
+The command-line examples below will assume that `build.proj` is selected by default and will omit
+it from the `dotnet build` command.
+
+If no target is specified, `build.proj` runs the `BuildAll` target by default, which builds all
+projects, tests, samples, and tools for all supported OS combinations. To build only the driver
+projects, specify `-t:BuildDriver` explicitly.
+
+The following build targets can be used to build the following projects. All targets will implicitly build any other
+projects they depend on.
+
+| `<build_target>`              | Description                                                                     |

+<!-- markdownlint-enable MD060 -->
+
+For most projects, build output is placed in `artifacts/<package_name>/Project-<configuration>/<tfm>`. `<package_name>`
+is the full name of the package, `<configuration>` is the build configuration, and `<tfm>` is the target framework
+moniker. SqlClient deviates slightly from this convention, since it consists of multiple projects and the
+implementation project is OS-specific. Implementation project output is placed in
+`artifacts/Microsoft.Data.SqlClient/Project-<configuration>/<os>/<tfm>`. The unsupported platform assemblies are placed
+in `artifacts/Microsoft.Data.SqlClient.unsupported/Project-<configuration>/<tfm>`, and the reference assemblies are
+placed in `artifacts/Microsoft.Data.SqlClient.ref/Project-<configuration>/<tfm>`.
+
+#### Examples
+
+Build everything (all projects, tests, samples, and tools) using the default target:
 
 ```bash
-msbuild -t:RunTests -p:DotnetPath=C:\net8-win-x86\
+dotnet build
 ```
 
-To run tests against a specific version of .NET/.NET Framework, set the `-p:TF` parameter.
+Build only the driver projects:
 
 ```bash
-msbuild -t:RunTests -p:TF=net8.0
-msbuild -t:RunTests -p:TF=net462
+dotnet build -t:BuildDriver
 ```
 
-## Example Commands to Run Tests using `dotnet`
+Build Microsoft.Data.SqlClient in Release configuration:
+
+```bash
+dotnet build -t:BuildSqlClient -p:Configuration=Release
+```
 
-Under the hood, the MSBuild commands to run tests use `dotnet` commands. But, if you wish to run
-them without the overhead of wrapping/unwrapping in MSBuild, you can run them directly.
+Build a specific version of Microsoft.Data.SqlClient.Extensions.Abstractions (Abstractions is part of the
+SqlClient family, so its version is set via the family parameter `PackageVersionSqlClient`):
 
-To change the processor architecture that runs the test (where possible, ie, x86 on x64), use the
-appropriate `dotnet` executable.
+```bash
+dotnet build -t:BuildAbstractions -p:PackageVersionSqlClient=7.1.0
+```
 
-By default, the tests will be executed on all supported .NET/.NET framework versions. To run on a
-specific version, pass the `-f` parameter with the desired version (eg `net9.0`).
+### Testing Projects
 
-The `--filter` parameter is used to select which tests run. The default `category!=failing&
-category!=flaky&category!=interactive` prevents tests that are known to be failing or flaky from
-running. To run a specific test, use `FullyQualifiedName=[fully qualified name of the test method]`
-as the filter parameter. To run all possible tests, even known failing and flaky ones, simply omit
-the filter parameter. Please note, however, that this will still omit tests that cannot run on the
-current platform or with the current test configuration (eg, Windows tests on Linux, or SQL DB tests
-when Azure Synapse is configured).
+This section provides a summary and brief example of how to execute tests for projects in this repository. **For more
+information about test procedures, including config file setup, see [TESTGUIDE.md](TESTGUIDE.md).**
 
-### Run Functional Tests
+From the root of your repository, run `dotnet build` against `build.proj` with a test target, following this pattern:
 
 ```bash
-dotnet test "src/Microsoft.Data.SqlClient/tests/FunctionalTests/Microsoft.Data.SqlClient.FunctionalTests.csproj" \
-  -p:Configuration=Release \
-  --filter "category!=failing&category!=flaky&category!=interactive"
+dotnet build -t:<test_target> [optional_parameters]
+```

+| `TestSqlClientFunctional`  | Runs the "functional" test project for Microsoft.Data.SqlClient. These are a mix of unit and integration tests against live servers.                |
+| `TestSqlClientManual`      | Runs the "manual" test project for Microsoft.Data.SqlClient. These are generally integration tests against live servers.                            |
+| `TestSqlClientUnit`        | Runs the unit test project for Microsoft.Data.SqlClient. These are a mix of unit tests and integration tests against simulated servers.             |

+
+<!-- markdownlint-enable MD060 -->
+
+#### Examples
+
+Run Microsoft.Data.SqlClient unit tests:
+
+```bash
+dotnet build -t:TestSqlClientUnit
 ```
 
-### Run Manual Tests
+Run Microsoft.Data.SqlClient manual test set 2:
 
 ```bash
-dotnet test "src/Microsoft.Data.SqlClient/tests/ManualTests/Microsoft.Data.SqlClient.ManualTests.csproj" \
-  -p:Configuration=Release \
-  --filter "category!=failing&category!=flaky&category!=interactive"
+dotnet build -t:TestSqlClientManual -p:TestSet=2
 ```
 
-### Run Unit Tests
+Run Microsoft.Data.SqlClient functional tests against x86 dotnet:
+
 ```bash
-dotnet test "src/Microsoft.Data.SqlClient/tests/UnitTests/Microsoft.Data.SqlClient.UnitTests.csproj" \
-  -p:Configuration=Release \
-  --filter "category!=failing&category!=flaky&category!=interactive"
+dotnet build -t:TestSqlClientFunctional -p:DotnetPath='C:\path\to\dotnet\x86\'
 ```
 
-## Testing with Package References
+Run all Microsoft.Data.SqlClient.Extensions.Azure unit tests, including interactive, but excluding failing tests:
 
-The MDS driver consists of several components, each of which produces its own
-NuGet package.  During development, components reference each other via
-`<ProjectReference>` properties by default.  This means that building
-and testing one component will implicitly build its project referenced
-dependencies.
+```bash
+dotnet build -t:TestAzure -p:TestFilters=category!=failing
+```
+
+Run Microsoft.Data.SqlClient functional tests against net8.0 runtime:
+
+```bash
+dotnet build -t:TestSqlClientFunctional -p:TestFramework=net8.0
+```
 
-Alternatively, the `ReferenceType` build property may be specified with a value
-of `Package`.  This will change inter-component dependencies to use
-`<PackageReference>` dependencies, and require that dependent components be
-built and packaged before building the depending component.  This will generate NuGet
-packages in the root packages/ directory, and will be automatically searched by NuGet
-(see our root `NuGet.config`).
+### Packaging Projects
 
-Then, you can specify `Package` references be used, for example:
+Just like building and testing the various projects in this repository, packaging the projects into NuGet packages is
+also handled by `build.proj`. From the root of your repository, run `dotnet build` against `build.proj` with a pack target,
+following this pattern:
 
 ```bash
-dotnet build -t:BuildLogging,PackLogging
-dotnet build -t:BuildSqlServer,PackSqlServer
-dotnet build -t:BuildAbstractions,PackAbstractions -p:ReferenceType=Package
-dotnet build -t:BuildAzure,PackAzure -p:ReferenceType=Package
-dotnet build -t:BuildSqlClient -p:ReferenceType=Package
-dotnet build -t:GenerateMdsPackage
-dotnet build -t:BuildAKVNetCore -p:ReferenceType=Package
-dotnet build -t:GenerateAkvPackage
+dotnet build -t:<pack_target> [optional_parameters]
 ```
 
-The above will build the MDS and AKV components, place their NuGet packages into
-the `packages/` directory.
+| `<pack_target>`    | Description                                                                         |
+|--------------------|-------------------------------------------------------------------------------------|
+| `Pack`             | Packages all projects in the repository.                                            |
+| `PackAbstractions` | Packages the Microsoft.Data.SqlClient.Extensions.Abstractions package               |
+| `PackAkvProvider`  | Packages the Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider package |
+| `PackAzure`        | Packages the Microsoft.Data.SqlClient.Extensions.Azure package                      |
+| `PackLogging`      | Packages the Microsoft.Data.SqlClient.Internal.Logging package                      |
+| `PackSqlClient`    | Packages the Microsoft.Data.SqlClient package                                       |
+| `PackSqlServer`    | Packages the Microsoft.SqlServer.Server package                                     |

-A non-AnyCPU platform reference can only be used with package reference type.
-Otherwise, the specified platform will be replaced with AnyCPU in the build
-process.
+For `PackSqlClient`, the SqlClient nuspec pins its family dependencies (Abstractions and Logging) to the same `SqlClientPackageVersion` value, so a single `-p:PackageVersionSqlClient=<version>` controls both the SqlClient package version and those dependency ranges. `Microsoft.SqlServer.Server` is pinned separately via `-p:PackageVersionSqlServer=<version>`.
 
-### Running Tests with Reference Type
+If omitted, `PackSqlClient` computes these versions from `Versions.props` using the current `BuildNumber` and `BuildSuffix` context.
+
+#### Examples
+
+Package Microsoft.Data.SqlClient.Internal.Logging into a NuGet package:
+
+```bash
+dotnet build -t:PackLogging
+```
 
-Provide property to `dotnet test` commands for testing desired reference type.
+Package Microsoft.Data.SqlClient:
 
 ```bash
-dotnet test -p:ReferenceType=Project ...
+dotnet build -t:PackSqlClient
 ```
 
+Package a specific version of Microsoft.Data.SqlClient.Extensions.Abstractions (set via the family parameter
+`PackageVersionSqlClient`):
+
+```bash
+dotnet build -t:PackAbstractions -p:PackageVersionSqlClient=7.1.0
+```
+
+Package Microsoft.Data.SqlClient.Extensions.Azure without building it beforehand:
+
+```bash
+dotnet build -t:PackAzure -p:PackBuild=false
+```
+
+## Versioning
+
+Versioning can be accomplished by using a mix of different parameters to the `build.proj` targets:
+`PackageVersionSqlClient` (or `PackageVersionSqlServer`), `BuildNumber`, and `BuildSuffix`. Using these in different
+combinations can generate appropriate package, assembly, and file versions for different scenarios. For most developer
+workflows, it is not necessary to specify any of these parameters - appropriate versions based on the latest release
+will be generated automatically. This section primarily exists to document the various parameters, their effects, and
+the scenarios they can be useful for.
+
+All packages in the **SqlClient family** (`Microsoft.Data.SqlClient`, `Internal.Logging`, `Extensions.Abstractions`,
+`Extensions.Azure`, and the AKV Provider) share a single version, set via `-p:PackageVersionSqlClient`.
+`Microsoft.SqlServer.Server` is versioned separately via `-p:PackageVersionSqlServer`.
+
+The SqlClient family version is defined in `src/Microsoft.Data.SqlClient/Versions.props` (and SqlServer's in its own
+`Versions.props`), which declares a "default" version — the next version to release. For the table below, we assume this
+is "1.2.3".
+
+| `PackageVersion` | `BuildNumber` | `BuildSuffix` | Package Version  | Assembly Version | File Version  | Scenario                                                   |

+| `9.8.7-preview1` | N/A           | N/A           | `9.8.7-preview1` | `9.0.0`          | `9.8.7.0`     | Developer is building a pre-release version of the package |
+| N/A              | `1234`        | N/A           | `1.2.3`          | `1.0.0`          | `1.2.3.1234`  | Automated pipelines building GA releases                   |

+
+## Package Mode Builds
+
+The above documentation is the default mode of operation, and is the recommended mode for most developers. However,
+`build.proj` supports "package mode" builds. In this mode, instead of projects depending on other projects, they
+depend on NuGet packages. This mode is useful for verifying that packages work with each other, especially in automated
+build scenarios. For completeness, and debugging of automated builds, this section documents behavior of "package mode".
+
+To switch to "package mode", set the `ReferenceType` parameter in `build.proj` to `Package`. And, optionally, include
+one or both of the following parameters:
+
+- `PackageVersionSqlClient` — the version for the entire SqlClient family.
+- `PackageVersionSqlServer` — the version for `Microsoft.SqlServer.Server`.
+
+These parameters pull double duty. In targets where a package is being built, the parameter sets the version of the
+package. In targets where a package is being referenced, the parameter sets the version of the referenced package.
+Because the SqlClient family shares one version, `PackageVersionSqlClient` covers every family package, whether it is
+being built or referenced.
+
+If these parameters are not specified, the latest version, as defined in the `Versions.props` file, will be used.
+
+The `nuget.config` for this repository defines a local feed that points to the `packages` directory. This allows
+developers that need to test against development packages to drop their development packages into this directory, and
+run subsequent `build.proj` targets against them.
+
+### Examples
+
+Build Microsoft.Data.SqlClient version 7.1.1 in package mode.  Because all SqlClient family packages share the same
+version, a single `-p:PackageVersionSqlClient=7.1.1` applies to SqlClient and its family dependencies (Abstractions and
+Logging).
+
+Build v7.1.1 of Logging and copy to packages:
+
+```bash
+dotnet build -t:PackLogging -p:ReferenceType=Package -p:PackageVersionSqlClient=7.1.1
+cp artifacts/Microsoft.Data.SqlClient.Internal.Logging/Debug/*.*pkg packages/
+```
+
+Build v7.1.1 of Abstractions (which depends on v7.1.1 of Logging):
+
+```bash
+dotnet build -t:PackAbstractions \
+  -p:ReferenceType=Package \
+  -p:PackageVersionSqlClient=7.1.1
+cp artifacts/Microsoft.Data.SqlClient.Extensions.Abstractions/Package-Debug/*.*pkg packages/
+```
+
+Build SqlClient:
+
+```bash
+dotnet build -t:PackSqlClient \
+  -p:ReferenceType=Package \
+  -p:PackageVersionSqlClient=7.1.1
+cp artifacts/Microsoft.Data.SqlClient/Package-Debug/*.*pkg packages/
+```
+
+Run Microsoft.Data.SqlClient functional tests against the versions built above:
+
+```bash
+dotnet build -t:TestSqlClientFunctional \
+  -p:ReferenceType=Package \
+  -p:PackageVersionSqlClient=7.1.1
+```
+
+Manual test prerequisites and configuration are covered in [TESTGUIDE.md](TESTGUIDE.md#manual-test-prerequisites).

 > **Note:** Releases are sorted in reverse chronological order (newest first).
 
+## [Stable Release 7.0.3] - 2026-09-10
+
+### Changed
+
+- Updated the `Microsoft.Data.SqlClient.SNI` and `Microsoft.Data.SqlClient.SNI.runtime` dependencies to 6.0.3 (was 6.0.2).
+  ([#4599](https://github.com/dotnet/SqlClient/pull/4599))
+
+### Fixed
+
+- Fixed a `SqlBulkCopy` regression in environments where the application login cannot read `sys.all_columns`. Bulk copy now falls back to the earlier column-discovery behavior when that permission is unavailable. Support for hidden columns and SQL Graph column aliases still requires access to the metadata view.
+  ([#4370](https://github.com/dotnet/SqlClient/issues/4370), [#4306](https://github.com/dotnet/SqlClient/pull/4306), [#4402](https://github.com/dotnet/SqlClient/pull/4402))
+
+- Fixed a memory-allocation regression in connection and command operations caused by formatting diagnostic strings even when tracing was disabled. Also corrected trace messages that reported an incorrect object ID or could throw `FormatException` when traced values contained braces.
+  ([#4528](https://github.com/dotnet/SqlClient/pull/4528), [#4533](https://github.com/dotnet/SqlClient/pull/4533))
+
+- Fixed `ServerCertificate` validation on the managed SNI path so the configured certificate is compared against the server certificate even when the server certificate passes chain and host-name validation. When certificate validation is enabled, a missing, unreadable, or invalid certificate file, a certificate mismatch, or a missing server certificate now causes the TLS handshake to fail instead of bypassing the configured certificate check. (net8.0/net9.0 only)
+  ([#4445](https://github.com/dotnet/SqlClient/pull/4445), [#4583](https://github.com/dotnet/SqlClient/pull/4583))
+
+- Fixed Always Encrypted VSM/HGS enclave attestation to verify that the enclave public key used to establish a session matches the key committed to by the signed attestation report. Missing, malformed, or mismatched key-binding data now causes attestation to fail before the session secret is derived.
+  ([#4532](https://github.com/dotnet/SqlClient/pull/4532), [#4553](https://github.com/dotnet/SqlClient/pull/4553))
+
+- Fixed `SqlConnection.AccessTokenCallback` not disabling Transparent Network IP Resolution by default, making it consistent with `SqlConnection.AccessToken`. An explicitly configured `TransparentNetworkIPResolution` connection-string value still takes precedence. (net462 only)
+  ([#4520](https://github.com/dotnet/SqlClient/pull/4520), [#4561](https://github.com/dotnet/SqlClient/pull/4561))
+
+- Fixed authentication state handling so clearing `SqlConnection.AccessToken`, `AccessTokenCallback`, or `SspiContextProvider` preserves the other authentication values in the connection pool key. Cloning a connection or updating its credential also preserves its `SspiContextProvider`. Combining a non-null `SspiContextProvider` with `AccessToken` or `AccessTokenCallback` now throws `InvalidOperationException` instead of silently discarding authentication state; applications must use one authentication mechanism at a time.
+  ([#4520](https://github.com/dotnet/SqlClient/pull/4520), [#4561](https://github.com/dotnet/SqlClient/pull/4561), [#4644](https://github.com/dotnet/SqlClient/pull/4644))
+
+- Fixed configurable retry logic installing a permanent, process-wide assembly-resolution handler that could interfere with unrelated assembly loading. The handler is now active only while an explicitly configured custom retry provider is resolved and constructed, and probes `AppContext.BaseDirectory` instead of the current working directory. Place custom retry assemblies in the application base directory; dependencies loaded after provider construction must be resolvable through normal application dependency resolution or an application-provided handler. (net8.0/net9.0 only)

+
+### Companion packages
+
+- Released `Microsoft.Data.SqlClient.Extensions.Azure` 7.0.3 with the Entra ID authority parsing fix for Dataverse/Dynamics 365 connections. See [release notes](release-notes/Extensions/Azure/7.0/7.0.3.md).
+- Released version-aligned `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`, `Microsoft.Data.SqlClient.Extensions.Abstractions`, and `Microsoft.Data.SqlClient.Internal.Logging` 7.0.3 with no functional or API changes. See the [Azure Key Vault provider](release-notes/add-ons/AzureKeyVaultProvider/7.0/7.0.3.md), [Abstractions](release-notes/Extensions/Abstractions/7.0/7.0.3.md), and [Logging](release-notes/Internal/Logging/7.0/7.0.3.md) release notes.

+## [Preview Release 7.1.0-preview3] - 2026-08-26
+
+This update brings the following changes since the [7.1.0-preview2](release-notes/7.1/7.1.0-preview2.md) release.
+See the [full release notes](release-notes/7.1/7.1.0-preview3.md) for detailed descriptions.
+
+> **Important — package version alignment:** Starting with the [7.0.2](release-notes/7.0/7.0.2.md) release, the `Microsoft.Data.SqlClient` driver and its companion packages share a single aligned version. Preview 3 of the `7.1` line continues this alignment; the following packages now ship together as `7.1.0-preview3`:
+>
+> - `Microsoft.Data.SqlClient`
+> - `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`
+> - `Microsoft.Data.SqlClient.Extensions.Azure`
+> - `Microsoft.Data.SqlClient.Extensions.Abstractions`
+> - `Microsoft.Data.SqlClient.Internal.Logging`
+>
+> (`Microsoft.SqlServer.Server` continues to version independently and remains at `1.0.0`.)
+>
+> Applications that reference `Microsoft.Data.SqlClient.Extensions.Azure` must upgrade it to `7.1.0-preview3` when upgrading `Microsoft.Data.SqlClient` to `7.1.0-preview3`.
+>
+> **Compatibility guarantee:** All aligned assemblies ship with `FileVersion 7.1.0.x` and `AssemblyVersion 7.0.0.0`. The `AssemblyVersion` is unchanged from [7.0.2](release-notes/7.0/7.0.2.md), so upgrading from `7.0.2` to `7.1.0-preview3` does **not** require any new .NET Framework strong-name binding redirects.
+
+### Added
+
+- Added four `virtual` asynchronous counterparts to the synchronous methods on `SqlColumnEncryptionKeyStoreProvider` — `DecryptColumnEncryptionKeyAsync`, `EncryptColumnEncryptionKeyAsync`, `SignColumnMasterKeyMetadataAsync`, and `VerifyColumnMasterKeyMetadataAsync` — each accepting an optional `CancellationToken`. The default implementations delegate to the existing synchronous methods, so existing custom providers are unaffected. These APIs are introduced for provider authors but are not consumed by the driver yet; a future release will enable their use from the driver's own asynchronous APIs.
+  ([#3673](https://github.com/dotnet/SqlClient/pull/3673))
+
+- Implemented those four asynchronous APIs in `SqlColumnEncryptionAzureKeyVaultProvider`, calling the Azure SDK's own asynchronous methods and flowing the supplied `CancellationToken`. Concurrent cache misses for the same key are gated so a burst of callers issues a single Key Vault request. See the [AKV release notes](release-notes/add-ons/AzureKeyVaultProvider/7.1/7.1.0-preview3.md) for the `VerifyColumnMasterKeyMetadata` signature-validation behavior change and the 7.1 runtime requirement.
+  ([#4540](https://github.com/dotnet/SqlClient/pull/4540))
+
+- Substantially expanded `ChannelDbConnectionPool` (the opt-in pool behind `Switch.Microsoft.Data.SqlClient.UseConnectionPoolV2`) to parity with the default pool: transaction support, broken-connection replacement, leaked-connection reclamation, background warmup and replenishment to `Min Pool Size`, idle pruning driven by `Connection Idle Timeout`, optional connection-creation rate limiting, and metrics/tracing parity. Default pooling behavior is unchanged.
+  ([#4395](https://github.com/dotnet/SqlClient/pull/4395),
+   [#4396](https://github.com/dotnet/SqlClient/pull/4396),
+   [#4429](https://github.com/dotnet/SqlClient/pull/4429),
+   [#4452](https://github.com/dotnet/SqlClient/pull/4452),
+   [#4463](https://github.com/dotnet/SqlClient/pull/4463),
+   [#4487](https://github.com/dotnet/SqlClient/pull/4487),
+   [#4504](https://github.com/dotnet/SqlClient/pull/4504),
+   [#4529](https://github.com/dotnet/SqlClient/pull/4529))
+
+### Changed
+
+- The driver now builds a single cross-platform assembly. Package structure and contents are unchanged, and Windows-only native SNI types now trim cleanly on Linux and macOS.
+  ([#4207](https://github.com/dotnet/SqlClient/pull/4207),
+   [#4465](https://github.com/dotnet/SqlClient/pull/4465),
+   [#4474](https://github.com/dotnet/SqlClient/pull/4474))
+
+- Reduced managed allocations in the async read path by restoring reuse of `PacketData` nodes via a bounded free list on `StateSnapshot`. This applies to the default async read path and is not gated behind any AppContext switch.
+  ([#4536](https://github.com/dotnet/SqlClient/pull/4536))
+
+- Operations no longer allocate a formatted trace string when `SqlClientEventSource` tracing is disabled, recovering a memory regression against the 6.1.6 baseline. Trace output with tracing enabled is unchanged.
+  ([#4528](https://github.com/dotnet/SqlClient/pull/4528))
+
+- Updated centrally managed dependency versions for the `net9.0` target framework to `9.0.18`, and added `System.Threading.RateLimiting` to the packaged dependency metadata. Non-`net9.0` targets keep their existing `8.0.x` pins.
+  ([#4507](https://github.com/dotnet/SqlClient/pull/4507))
+
+- Updated the `Microsoft.Data.SqlClient.SNI` and `Microsoft.Data.SqlClient.SNI.runtime` dependencies to `7.1.0-preview3.26226.3`.
+  ([#4564](https://github.com/dotnet/SqlClient/pull/4564))
+
+- Bypassed SQL Graph column alias mapping in `SqlBulkCopy` when neither the source nor destination table contains graph pseudo-columns, recovering a bulk copy performance regression. Graph table bulk copy behavior is unchanged.
+  ([#4535](https://github.com/dotnet/SqlClient/pull/4535))
+
+- Re-shipped `Microsoft.Data.SqlClient.Extensions.Azure` as `7.1.0-preview3`, fixing Entra ID tenant parsing for multi-segment authorities. See [release notes](release-notes/Extensions/Azure/7.1/7.1.0-preview3.md).
+
+- Re-shipped `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider` as `7.1.0-preview3` with new asynchronous key store provider APIs, and `Microsoft.Data.SqlClient.Extensions.Abstractions` and `Microsoft.Data.SqlClient.Internal.Logging` as `7.1.0-preview3` (version alignment only, no functional changes). See release notes for [AKV](release-notes/add-ons/AzureKeyVaultProvider/7.1/7.1.0-preview3.md), [Abstractions](release-notes/Extensions/Abstractions/7.1/7.1.0-preview3.md), and [Logging](release-notes/Internal/Logging/7.1/7.1.0-preview3.md).
+
+### Fixed
+
+- Fixed Always Encrypted VSM/HGS enclave attestation not verifying that the enclave public key used to establish the session matches the key committed to by the signed attestation report.
+  ([#4532](https://github.com/dotnet/SqlClient/pull/4532))
+
+- Fixed a `SqlConnectionFactory` timer that woke the process every 30 seconds for the lifetime of the application even when no connection pools existed, including with `Pooling=False` and after `ClearAllPools()`.
+  ([#4479](https://github.com/dotnet/SqlClient/pull/4479))
+
+- Fixed connection pool performance counter defects affecting the default pool as well as pool V2. `active-soft-connects` and `number-of-active-connections` could go negative after a failed connection activation, and several gauges drifted upward permanently after a broken connection was replaced.
+  ([#4504](https://github.com/dotnet/SqlClient/pull/4504))
+
+- Fixed `OverflowException` when sending large `decimal` values as a parameter with explicit `Precision` and `Scale`, which primarily affected Always Encrypted scenarios.
+  ([#4443](https://github.com/dotnet/SqlClient/pull/4443))
+
+- Fixed a TDS stream error when passing a `DateOnly` value as a parameter with `SqlDbType.Variant`.
+  ([#4294](https://github.com/dotnet/SqlClient/pull/4294))
+
+- Fixed `DateOnly` values written to a `sql_variant` column of a table-valued parameter being sent as `datetime` instead of `date`, which also caused an overflow for values out of `datetime` range.
+  ([#4439](https://github.com/dotnet/SqlClient/pull/4439))
+
+- Fixed the `ServerCertificate` connection-string keyword not being honored when the platform reported no TLS policy errors, and made an unloadable certificate file fail closed instead of silently falling back to host-name validation.
+  ([#4445](https://github.com/dotnet/SqlClient/pull/4445))
+
+- Fixed `SqlConnection.AccessTokenCallback` not disabling Transparent Network IP Resolution by default, unlike `SqlConnection.AccessToken`, along with a related connection pool key defect.
+  ([#4520](https://github.com/dotnet/SqlClient/pull/4520))
+
+- Fixed several async entry points in `SqlBulkCopy`, `SqlDataReader`, and `SqlCommand` that captured fatal exceptions such as `OutOfMemoryException` into faulted `Task`s instead of letting them propagate.
+  ([#4437](https://github.com/dotnet/SqlClient/pull/4437))
+
+- Fixed `Authentication=Active Directory Service Principal` (and the other Entra ID flows) failing against endpoints that return a multi-segment authority such as the Dataverse / Dynamics 365 TDS endpoint; the tenant id is now taken from the first path segment of the STSURL authority instead of the last. Ships in `Microsoft.Data.SqlClient.Extensions.Azure`.
+  ([#4521](https://github.com/dotnet/SqlClient/pull/4521))
+
+## [Preview Release 7.1.0-preview2] - 2026-07-09
+
+This update brings the following changes since the [7.1.0-preview1](release-notes/7.1/7.1.0-preview1.md) release.
+See the [full release notes](release-notes/7.1/7.1.0-preview2.md) for detailed descriptions.
+
+> **Important — package version alignment:** Starting with the [7.0.2](release-notes/7.0/7.0.2.md) release, the `Microsoft.Data.SqlClient` driver and its companion packages share a single aligned version. Preview 2 of the `7.1` line continues this alignment; the following packages now ship together as `7.1.0-preview2`:
+>
+> - `Microsoft.Data.SqlClient`
+> - `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`
+> - `Microsoft.Data.SqlClient.Extensions.Azure`
+> - `Microsoft.Data.SqlClient.Extensions.Abstractions`
+> - `Microsoft.Data.SqlClient.Internal.Logging`
+>
+> (`Microsoft.SqlServer.Server` continues to version independently and remains at `1.0.0`.)
+>
+> Applications that reference `Microsoft.Data.SqlClient.Extensions.Azure` must upgrade it to `7.1.0-preview2` when upgrading `Microsoft.Data.SqlClient` to `7.1.0-preview2`.
+>
+> **Compatibility guarantee:** All aligned assemblies ship with `FileVersion 7.1.0.x` and `AssemblyVersion 7.0.0.0`. The `AssemblyVersion` is unchanged from [7.0.2](release-notes/7.0/7.0.2.md), so upgrading from `7.0.2` to `7.1.0-preview2` does **not** require any new .NET Framework strong-name binding redirects. See the 7.0.2 release notes for the original `AssemblyVersion` alignment (the one-time breaking change that raised `AssemblyVersion` from `1.0.0.0` to `7.0.0.0` for `Extensions.Azure`, `Extensions.Abstractions`, and `Internal.Logging`; `AzureKeyVaultProvider` was already on `7.x`).
+
+### Added
+
+- Added `SqlConnection.GetSchemaAsync` overloads mirroring the existing synchronous shapes.
+  ([#3005](https://github.com/dotnet/SqlClient/pull/3005))
+
+- Added SQL Graph column-alias support (`$node_id`, `$edge_id`, `$from_id`, `$to_id`) as destination columns in `SqlBulkCopy`.
+  ([#3677](https://github.com/dotnet/SqlClient/pull/3677))
+
+- `SqlBatchCommand.CommandBehavior` (a driver-specific property that existed since batching was introduced but was previously ignored) is now honored during `SqlBatch` execution, and `SqlBatch.ExecuteReader` now respects the `CommandBehavior` value passed to it.
+  ([#4125](https://github.com/dotnet/SqlClient/pull/4125))
+
+- Added a `Connection Idle Timeout` connection-string keyword and matching `SqlConnectionStringBuilder.IdleTimeout` property to evict idle pooled connections (default `300` seconds; `0` disables). Enforcement is opt-in via `Switch.Microsoft.Data.SqlClient.UseLegacyIdleTimeoutBehavior=false`; the default preserves the historical pooling behavior. When enabled, idle-timeout enforcement applies to the existing connection pool as well.
+  ([#4295](https://github.com/dotnet/SqlClient/pull/4295))
+
+### Changed
+
+- The `Connect Timeout` budget can now be propagated through pool acquisition via a shared `TimeoutTimer`, so time spent waiting in the pool is deducted from the overall timeout. Enforcement is opt-in via `Switch.Microsoft.Data.SqlClient.UseOverallConnectTimeoutForPoolWait=true`; the default (`false`) preserves the historical behavior where pool waits do not count against `Connect Timeout`. Adds a dependency on `Microsoft.Bcl.TimeProvider`.
+  ([#4270](https://github.com/dotnet/SqlClient/pull/4270))
+
+- Hardened `SqlConnection` internal state transitions with `Interlocked.CompareExchange` guards.
+  ([#4267](https://github.com/dotnet/SqlClient/pull/4267))
+
+- Removed legacy connection-options inheritance from internal APIs and simplified `TryOpenConnection` / `TryReplaceConnection` / pool interfaces.
+  ([#4235](https://github.com/dotnet/SqlClient/pull/4235),
+   [#4237](https://github.com/dotnet/SqlClient/pull/4237),
+   [#4261](https://github.com/dotnet/SqlClient/pull/4261),
+   [#4415](https://github.com/dotnet/SqlClient/pull/4415))
+
+- Added the SQL Server 2025 `json` data type to the `DataTypes` schema table returned by `SqlConnection.GetSchema`.
+  ([#3858](https://github.com/dotnet/SqlClient/pull/3858))
+
+- Added async generic helpers to reduce sync/async duplication.
+  ([#4334](https://github.com/dotnet/SqlClient/pull/4334))
+
+- Use hardcoded LCID mappings when decoding strings.
+  ([#4212](https://github.com/dotnet/SqlClient/pull/4212))
+
+- Reduced allocations by skipping lock acquisition on `SqlErrorCollection` counters when no errors exist, and by avoiding stack-trace materialization on expected `null`-return paths.
+  ([#4099](https://github.com/dotnet/SqlClient/pull/4099),
+   [#4102](https://github.com/dotnet/SqlClient/pull/4102),
+   [#4157](https://github.com/dotnet/SqlClient/pull/4157))
+
+- Improved accuracy of `EnclaveDiffieHellmanInfo.Size`.
+  ([#4346](https://github.com/dotnet/SqlClient/pull/4346))
+
+- `SqlVector<float>` now serializes and deserializes multibyte values as little-endian explicitly.
+  ([#3861](https://github.com/dotnet/SqlClient/pull/3861))
+
+- Updated the bundled .NET 10 SDK to `10.0.300`.
+  ([#4287](https://github.com/dotnet/SqlClient/pull/4287))
+
+- Re-shipped `Microsoft.Data.SqlClient.Extensions.Azure` as `7.1.0-preview2`, adding Windows Account Manager (WAM) broker support for Entra ID authentication on Windows. See [release notes](release-notes/Extensions/Azure/7.1/7.1.0-preview2.md).
+
+- Re-shipped `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`, `Microsoft.Data.SqlClient.Extensions.Abstractions`, and `Microsoft.Data.SqlClient.Internal.Logging` as `7.1.0-preview2` (version alignment only, no functional changes). See release notes for [AKV](release-notes/add-ons/AzureKeyVaultProvider/7.1/7.1.0-preview2.md), [Abstractions](release-notes/Extensions/Abstractions/7.1/7.1.0-preview2.md), and [Logging](release-notes/Internal/Logging/7.1/7.1.0-preview2.md).
+
+### Fixed
+
+- Fixed a `NullReferenceException` in `SqlCommand.Cancel()` when the active connection has already been torn down.
+  ([#4372](https://github.com/dotnet/SqlClient/pull/4372))
+
+- Fixed Always Encrypted column master key signature verification incorrectly reusing cached results after a prior verification failure.
+  ([#4339](https://github.com/dotnet/SqlClient/pull/4339))
+
+- Fixed missing bounds checks on TDS token and feature-extension-acknowledgment data lengths that could allow a spoofing server to trigger unbounded allocations.
+  ([#4340](https://github.com/dotnet/SqlClient/pull/4340))
+
+- Fixed `SqlBulkCopy` failing in least-privilege environments.
+  ([#4306](https://github.com/dotnet/SqlClient/pull/4306))
+
+- Fixed Always Encrypted reads of `CekMdVersion` and `EkValueCount` to align with the TDS specification.
+  ([#4240](https://github.com/dotnet/SqlClient/pull/4240))
+
+- Fixed `LoginWithFailover` to validate parser state before continuing.
+  ([#4140](https://github.com/dotnet/SqlClient/pull/4140))
+
+- Fixed the SPN used during login to use the resolved port instead of the instance name when `Protocol=None` or `Protocol=Admin`.
+  ([#4180](https://github.com/dotnet/SqlClient/pull/4180))
+
+- Fixed a race in `SqlConnection.TryOpenInner` that could surface as `InvalidCastException`; the same race now returns a deterministic `InvalidOperationException`.
+  ([#4179](https://github.com/dotnet/SqlClient/pull/4179))
+
+- Fixed several `CancellationTokenSource` leaks across `SqlDataReader`, `SqlConnection` reconnect, `SqlCommand` reconnect timeout, and sequential-stream helpers.
+  ([#4009](https://github.com/dotnet/SqlClient/pull/4009))
+
+- Fixed server certificate documentation.
+  ([#4408](https://github.com/dotnet/SqlClient/pull/4408))
+
+### Removed
+
+- **Breaking:** Removed SQL Server 7.0 and SQL Server 2000 support, along with the `TypeSystem.SQLServer2000` enum value and the `Type System Version=SQL Server 2000` connection-string value. Connection strings that specify this value now throw `ArgumentException` when the connection is opened. Supported values are `Latest`, `SQL Server 2005`, `SQL Server 2008`, and `SQL Server 2012`.
+  ([#4015](https://github.com/dotnet/SqlClient/pull/4015))
+
+## [Stable Release 7.0.2] - 2026-06-24
+
+This update brings the following changes since the [7.0.1](release-notes/7.0/7.0.1.md) release.
+See the [full release notes](release-notes/7.0/7.0.2.md) for detailed descriptions.
+
+> **Important — package version alignment:** Starting with 7.0.2, the `Microsoft.Data.SqlClient` driver and its companion packages share a single aligned version. The following packages now ship together as `7.0.2`:
+>
+> - `Microsoft.Data.SqlClient`
+> - `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`
+> - `Microsoft.Data.SqlClient.Extensions.Azure`
+> - `Microsoft.Data.SqlClient.Extensions.Abstractions`
+> - `Microsoft.Data.SqlClient.Internal.Logging`
+>
+> (`Microsoft.SqlServer.Server` continues to version independently and remains at `1.0.0`.)
+>
+> Applications must reference the same versions of `Microsoft.Data.SqlClient` and its extensions for best compatibility. In particular, applications that reference `Microsoft.Data.SqlClient.Extensions.Azure` must upgrade it to `7.0.2` when upgrading `Microsoft.Data.SqlClient` to `7.0.2`.
+
+> **Breaking change (.NET Framework only):** As part of this alignment, the `AssemblyVersion` of `Microsoft.Data.SqlClient.Extensions.Azure`, `Microsoft.Data.SqlClient.Extensions.Abstractions`, and `Microsoft.Data.SqlClient.Internal.Logging` changed from `1.0.0.0` to `7.0.0.0`. On .NET Framework, `AssemblyVersion` is part of the strong-name identity, so applications that drop these assemblies into an existing deployment without rebuilding must rebuild against the 7.0.2 packages (or add binding redirects). Applications on .NET / .NET Core are not affected. `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider` already used a `7.x` assembly version and is unaffected.
+
+### Fixed
+
+- Fixed a `NullReferenceException` in `SqlCommand.Cancel()` when the active connection has already been torn down.
+  ([#4372](https://github.com/dotnet/SqlClient/pull/4372),
+   [#4373](https://github.com/dotnet/SqlClient/pull/4373))
+
+- Fixed a `NullReferenceException` in `SqlDataReader.GetBytes`/`GetChars` when called with a `null` destination buffer.
+  ([#4159](https://github.com/dotnet/SqlClient/pull/4159),
+   [#4206](https://github.com/dotnet/SqlClient/pull/4206))
+
+- Fixed Always Encrypted column master key signature verification incorrectly reusing cached results.
+  ([#4339](https://github.com/dotnet/SqlClient/pull/4339),
+   [#4343](https://github.com/dotnet/SqlClient/pull/4343))
+
+### Changed
+
+- Hardened TDS token parsing by adding data-length bounds checks for token and feature-extension-acknowledgment data.
+  ([#4340](https://github.com/dotnet/SqlClient/pull/4340),
+   [#4358](https://github.com/dotnet/SqlClient/pull/4358))
+
+- Released `Microsoft.Data.SqlClient.Extensions.Azure 7.0.2`, adding WAM broker support for Entra ID authentication modes on Windows. See [release notes](release-notes/Extensions/Azure/7.0/7.0.2.md).
+  ([#4288](https://github.com/dotnet/SqlClient/pull/4288),
+   [#4388](https://github.com/dotnet/SqlClient/pull/4388))
+
+- Re-shipped `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`, `Microsoft.Data.SqlClient.Extensions.Abstractions`, and `Microsoft.Data.SqlClient.Internal.Logging` as `7.0.2` (version alignment only, no functional changes). See release notes for [AKV](release-notes/add-ons/AzureKeyVaultProvider/7.0/7.0.2.md), [Abstractions](release-notes/Extensions/Abstractions/7.0/7.0.2.md), and [Logging](release-notes/Internal/Logging/7.0/7.0.2.md).
+
+## [Stable Release 6.1.6] - 2026-06-24
+
+This update brings the following changes since the [6.1.5](release-notes/6.1/6.1.5.md) release.
+See the [full release notes](release-notes/6.1/6.1.6.md) for detailed descriptions.
+
+### Added
+
+- Added Web Account Manager (WAM) broker support for the supported Entra ID authentication modes (Windows only), including the new `ActiveDirectoryAuthenticationProviderOptions` type with a `UseWamBroker` property, an `ActiveDirectoryAuthenticationProvider(ActiveDirectoryAuthenticationProviderOptions options)` constructor overload, and a cross-platform `SetParentActivityOrWindowFunc(Func<object>)` method.
+  ([#4288](https://github.com/dotnet/SqlClient/pull/4288),
+   [#4387](https://github.com/dotnet/SqlClient/pull/4387))
+
+### Changed
+
+- Hardened TDS token parsing with data-length bounds checks to prevent unbounded memory allocation from a server spoofing length fields.
+  ([#4340](https://github.com/dotnet/SqlClient/pull/4340),
+   [#4359](https://github.com/dotnet/SqlClient/pull/4359))
+
+- Updated dependencies ([#4387](https://github.com/dotnet/SqlClient/pull/4387)):
+  - Updated `Microsoft.Identity.Client` to 4.84.2 (was 4.80.0)
+  - Added `Microsoft.Identity.Client.Broker` 4.84.2
+
+### Fixed
+
+- Fixed a `NullReferenceException` in `SqlDataReader.GetChars` on the PLP + `SequentialAccess` path when a `null` buffer was passed with a negative `bufferIndex`; it now throws `ArgumentOutOfRangeException`.
+  ([#4159](https://github.com/dotnet/SqlClient/pull/4159),
+   [#4205](https://github.com/dotnet/SqlClient/pull/4205))
+
+- Fixed column master key (CMK) signature verification caching where a cached verification failure could subsequently be reported as a valid signature.
+  ([#4339](https://github.com/dotnet/SqlClient/pull/4339),
+   [#4356](https://github.com/dotnet/SqlClient/pull/4356))
+
+## [Preview Release 7.1.0-preview1] - 2026-04-29
+
+This update brings the following changes since the [7.0.0](release-notes/7.0/7.0.0.md) release.
+See the [full release notes](release-notes/7.1/7.1.0-preview1.md) for detailed descriptions.
+
+### Added
+
+- Added `SqlBatch` support on .NET Framework so the batching API is available across the full supported platform matrix.
+  ([#3926](https://github.com/dotnet/SqlClient/pull/3926))
+
+- Added additional accepted connection-string synonyms for cross-driver alignment, including `ColumnEncryption`, `ConnectTimeout`, `FailoverPartner`, `PacketSize`, and `WorkstationId`.
+  ([#4192](https://github.com/dotnet/SqlClient/pull/4192))
+
+### Changed
+
+- `SqlConnection.ClearPool` and `SqlConnection.ClearAllPools` now work correctly with the channel-based pool implementation.
+  ([#4194](https://github.com/dotnet/SqlClient/pull/4194))
+
+- Added type forwards for public authentication abstractions moved into `Microsoft.Data.SqlClient.Extensions.Abstractions`.
+  ([#4067](https://github.com/dotnet/SqlClient/pull/4067),
+   [#4117](https://github.com/dotnet/SqlClient/pull/4117))
+
+- Enabled the User Agent feature extension by default.
+  ([#4124](https://github.com/dotnet/SqlClient/pull/4124),
+   [#4154](https://github.com/dotnet/SqlClient/pull/4154))
+
+- Reduced allocations when sending large string values, plus related source-build and packaging consolidation updates.
+  ([#4072](https://github.com/dotnet/SqlClient/pull/4072),
+   [#4033](https://github.com/dotnet/SqlClient/pull/4033),
+   [#4068](https://github.com/dotnet/SqlClient/pull/4068),
+   [#4204](https://github.com/dotnet/SqlClient/pull/4204))
+
+### Fixed
+
+- Fixed `SqlBulkCopy` on SQL Server 2016 graph tables by extracting graph metadata with dynamic SQL.
+  ([#3714](https://github.com/dotnet/SqlClient/issues/3714),
+   [#4092](https://github.com/dotnet/SqlClient/pull/4092),
+   [#4147](https://github.com/dotnet/SqlClient/pull/4147))
+
+- Fixed `SqlBulkCopy` support for Azure Synapse Analytics dedicated SQL pools.
+  ([#4149](https://github.com/dotnet/SqlClient/issues/4149),
+   [#4176](https://github.com/dotnet/SqlClient/pull/4176),
+   [#4182](https://github.com/dotnet/SqlClient/pull/4182))
+
+- Fixed vector float32 metadata so `GetFieldType()` and `GetProviderSpecificFieldType()` return the expected vector type.
+  ([#4104](https://github.com/dotnet/SqlClient/issues/4104),
+   [#4105](https://github.com/dotnet/SqlClient/pull/4105),
+   [#4152](https://github.com/dotnet/SqlClient/pull/4152))
+
+- Added the missing `System.Data.Common` dependency for .NET Framework consumers.
+  ([#4063](https://github.com/dotnet/SqlClient/pull/4063),
+   [#4074](https://github.com/dotnet/SqlClient/pull/4074))
+
+- Fixed a `SqlDataReader` streaming bug triggered by calling `IsDBNull()` before reading streamed column data.
+  ([#4082](https://github.com/dotnet/SqlClient/pull/4082))
+
+- Fixed a `NullReferenceException` in `SqlDataReader`.
+  ([#4159](https://github.com/dotnet/SqlClient/pull/4159))
+
+## [Stable Release 6.1.5] - 2026-04-27
+
+This update brings the following changes since the [6.1.4](release-notes/6.1/6.1.4.md) release.
+See the [full release notes](release-notes/6.1/6.1.5.md) for target platform support and dependency information.
+
+### Fixed
+
+- Fixed a connection performance regression where SPN (Service Principal Name) generation was triggered for non-integrated authentication modes (e.g., SQL authentication) on the native SNI path, causing unnecessary DNS lookups and significantly slower connection times.
+  ([#3523](https://github.com/dotnet/SqlClient/issues/3523), [#3946](https://github.com/dotnet/SqlClient/pull/3946))
+
+- Fixed `ExecuteScalar` to properly propagate errors when the server sends data followed by an error token. Previously, errors such as conversion failures during `WHERE` clause evaluation were silently consumed during `SqlDataReader.Close()` instead of being thrown to the caller, which could result in transactions being unexpectedly zombied.
+  ([#3736](https://github.com/dotnet/SqlClient/issues/3736), [#3947](https://github.com/dotnet/SqlClient/pull/3947))
+
+- Fixed `SqlDataReader.GetFieldType` and `SqlDataReader.GetProviderSpecificFieldType` to return the correct type (`SqlVector<float>`) for vector float32 columns.
+  ([#4104](https://github.com/dotnet/SqlClient/issues/4104), [#4151](https://github.com/dotnet/SqlClient/pull/4151))
+
+## [Stable Release 7.0.1] - 2026-04-23
+
+This update brings the following changes since the [7.0.0](release-notes/7.0/7.0.0.md) release.
+See the [full release notes](release-notes/7.0/7.0.1.md) for detailed descriptions.
+
+### Fixed
+
+- Fixed `SqlBulkCopy` failing on SQL Server 2016 with `Invalid column name 'graph_type'` error by using dynamic SQL to extract column names.
+  ([#3714](https://github.com/dotnet/SqlClient/issues/3714),
+   [#4092](https://github.com/dotnet/SqlClient/pull/4092),
+   [#4147](https://github.com/dotnet/SqlClient/pull/4147))
+
+- Fixed `SqlBulkCopy` failing on Azure Synapse Analytics dedicated SQL pools by using `STRING_AGG` for the column-list query when targeting Synapse.
+  ([#4149](https://github.com/dotnet/SqlClient/issues/4149),
+   [#4176](https://github.com/dotnet/SqlClient/pull/4176),
+   [#4182](https://github.com/dotnet/SqlClient/pull/4182))
+
+- Fixed `SqlDataReader.GetFieldType()` and `GetProviderSpecificFieldType()` returning incorrect type for vector float32 columns.
+  ([#4104](https://github.com/dotnet/SqlClient/issues/4104),
+   [#4105](https://github.com/dotnet/SqlClient/pull/4105),
+   [#4152](https://github.com/dotnet/SqlClient/pull/4152))
+
+- Added missing `System.Data.Common` (v4.3.0) NuGet package dependency for .NET Framework consumers to resolve `CS0012` compilation errors.
+  ([#4063](https://github.com/dotnet/SqlClient/pull/4063),
+   [#4074](https://github.com/dotnet/SqlClient/pull/4074))
+
+### Changed
+
+- Enabled the User Agent TDS feature extension unconditionally; removed the `Switch.Microsoft.Data.SqlClient.EnableUserAgent` AppContext switch.
+  ([#4124](https://github.com/dotnet/SqlClient/pull/4124),
+   [#4154](https://github.com/dotnet/SqlClient/pull/4154))
+
+- Added type forwards from the core assembly to public types moved to `Microsoft.Data.SqlClient.Extensions.Abstractions`.
+  ([#4067](https://github.com/dotnet/SqlClient/pull/4067),
+   [#4117](https://github.com/dotnet/SqlClient/pull/4117))
+
+- Fixed API documentation include paths and duplicate doc snippets.
+  ([#4084](https://github.com/dotnet/SqlClient/pull/4084),
+   [#4086](https://github.com/dotnet/SqlClient/pull/4086),
+   [#4107](https://github.com/dotnet/SqlClient/pull/4107),
+   [#4161](https://github.com/dotnet/SqlClient/pull/4161))
+
+## [Stable Release 7.0.0] - 2026-03-17
+
+This section summarizes all changes across the 7.0 preview cycle for users upgrading from the latest 6.1 stable release.
+See the [full release notes](release-notes/7.0/7.0.0.md) for detailed descriptions.
+
+Also released as part of this milestone:
+- Released Microsoft.Data.SqlClient.Extensions.Abstractions 1.0.0. See [release notes](release-notes/Extensions/Abstractions/1.0/1.0.0.md).
+- Released Microsoft.Data.SqlClient.Extensions.Azure 1.0.0. See [release notes](release-notes/Extensions/Azure/1.0/1.0.0.md).
+- Released Microsoft.Data.SqlClient.Internal.Logging 1.0.0. See [release notes](release-notes/Internal/Logging/1.0/1.0.0.md).
+- Released Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider 7.0.0. See [release notes](release-notes/add-ons/AzureKeyVaultProvider/7.0/7.0.0.md).
+
+### Changed
+
+- **Breaking:** Removed Azure dependencies from the core package. Entra ID authentication (`ActiveDirectoryAuthenticationProvider` and related types) has been extracted into a new `Microsoft.Data.SqlClient.Extensions.Azure` package. The core `Microsoft.Data.SqlClient` package no longer depends on `Azure.Core`, `Azure.Identity`, or their transitive dependencies. Applications using Entra ID authentication must now install `Microsoft.Data.SqlClient.Extensions.Azure` separately.
+  ([#1108](https://github.com/dotnet/SqlClient/issues/1108),
+   [#3680](https://github.com/dotnet/SqlClient/pull/3680),
+   [#3902](https://github.com/dotnet/SqlClient/pull/3902),
+   [#3904](https://github.com/dotnet/SqlClient/pull/3904),
+   [#3908](https://github.com/dotnet/SqlClient/pull/3908),
+   [#3917](https://github.com/dotnet/SqlClient/pull/3917),
+   [#3982](https://github.com/dotnet/SqlClient/pull/3982),
+   [#3978](https://github.com/dotnet/SqlClient/pull/3978),
+   [#3986](https://github.com/dotnet/SqlClient/pull/3986))
+
+- Two additional packages were introduced to support this separation: `Microsoft.Data.SqlClient.Extensions.Abstractions` (shared types between the core driver and extensions) and `Microsoft.Data.SqlClient.Internal.Logging` (shared ETW tracing infrastructure).
+  ([#3626](https://github.com/dotnet/SqlClient/pull/3626),
+   [#3628](https://github.com/dotnet/SqlClient/pull/3628),
+   [#3967](https://github.com/dotnet/SqlClient/pull/3967),
+   [#4038](https://github.com/dotnet/SqlClient/pull/4038))
+
+- Deprecated `SqlAuthenticationMethod.ActiveDirectoryPassword` (ROPC flow). The method is now marked `[Obsolete]` and will generate compiler warnings. Migrate to `ActiveDirectoryInteractive`, `ActiveDirectoryServicePrincipal`, `ActiveDirectoryManagedIdentity`, or `ActiveDirectoryDefault`.
+  ([#3671](https://github.com/dotnet/SqlClient/pull/3671))
+
+- Reverted public visibility of internal interop enums (`IoControlCodeAccess` and `IoControlTransferType`) that were accidentally made public during the project merge.

+## Submitting Pull Requests
+
+- **New features from community PRs must be driven by creating a GitHub issue first.** Discuss the proposal in the issue before starting implementation. This helps avoid wasted effort and ensures alignment with project goals.
+- **Community contributions must align with project priorities.** We prioritize features and fixes according to our [published milestones](https://github.com/dotnet/SqlClient/milestones). PRs that conflict with or distract from active work may be deferred.
+- **Our maintainers reserve the right to reject PRs** that do not meet the required criteria to qualify for review. This includes PRs that:
+  - Lack a corresponding approved issue (i.e., an issue that has been reviewed, acknowledged, and agreed upon by maintainers — typically indicated by the **`PM Approved`** field being set to **`Approved`** in the GitHub Project board)
+  - Introduce breaking changes without prior discussion
+  - Do not follow the project's coding standards and conventions
+  - Are missing adequate test coverage
+  - Conflict with work already in progress by the team
+- **Bug fixes and small improvements** are generally welcome without a prior issue, but a linked issue helps us triage and prioritize your contribution.
+
+### What Makes a Great Contribution
+
+1. **Start with an issue** — File a [feature request](https://github.com/dotnet/SqlClient/issues/new?template=feature_request.md) or [bug report](https://github.com/dotnet/SqlClient/issues/new?template=bug-report.md) and wait for maintainer feedback
+2. **Follow the conventions** — See [coding guidelines](policy/coding-style.md)
+3. **Include tests** — Both unit tests and integration tests where applicable
+4. **Keep scope focused** — One feature or fix per PR
+5. **Update documentation** — For any public API changes
+
+### Contribution Workflow
+
+See [contributing-workflow.md](contributing-workflow.md) for details on how PRs are tracked through our review process.
+
+## Feedback
+
+The best way to give feedback is to create issues in the [dotnet/SqlClient](https://github.com/dotnet/SqlClient) repo.
+
+Please give us feedback that will provide insight on the following:
+
+- Existing features that are missing some capability or otherwise don't work well enough.
+- Missing features that should be added to the product.
+- Design choices for a feature that is currently in-progress.
+
+Some important caveats:
+
+- It is best to give design feedback quickly for improvements that are in development. We're unlikely to hold a feature from a release on late feedback.
+- We are most likely to include improvements that either have a positive impact on a broad scenario or have very significant positive impact on a niche scenario. This means that we are unlikely to prioritize modest improvements to niche scenarios.
+- Compatibility will almost always be given a higher priority than improvements.
+
 ## Contribution Standards
 
-Project maintainers will merge changes that improve the product significantly and broadly and that align with the [Microsoft.Data.SqlClient roadmap](roadmap.md).

+# Test Guide for Microsoft.Data.SqlClient
+
+This guide describes how to run the test projects in this repository and how to configure the SQL Server-backed manual
+tests.
+
+For build prerequisites and general `build.proj` usage, see [BUILDGUIDE.md](BUILDGUIDE.md).
+
+## Test Projects
+
+The primary test projects for Microsoft.Data.SqlClient are under
+[src/Microsoft.Data.SqlClient/tests](src/Microsoft.Data.SqlClient/tests):
+
+| Project          | Path                                                                                                                                                                                                     | Purpose                                                                                                           |
+|------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------|
+| Unit tests       | [src/Microsoft.Data.SqlClient/tests/UnitTests/Microsoft.Data.SqlClient.UnitTests.csproj](src/Microsoft.Data.SqlClient/tests/UnitTests/Microsoft.Data.SqlClient.UnitTests.csproj)                         | Unit tests and tests against simulated servers.                                                                   |
+| Functional tests | [src/Microsoft.Data.SqlClient/tests/FunctionalTests/Microsoft.Data.SqlClient.FunctionalTests.csproj](src/Microsoft.Data.SqlClient/tests/FunctionalTests/Microsoft.Data.SqlClient.FunctionalTests.csproj) | Functional tests for public and internal behavior. Some tests use simulated servers or local test infrastructure. |
+| Manual tests     | [src/Microsoft.Data.SqlClient/tests/ManualTests/Microsoft.Data.SqlClient.ManualTests.csproj](src/Microsoft.Data.SqlClient/tests/ManualTests/Microsoft.Data.SqlClient.ManualTests.csproj)                 | Integration tests that generally require a configured SQL Server or Azure SQL target.                             |
+
+These projects target `net8.0`, `net9.0`, and `net10.0` on all platforms. On Windows, they also target `net462`.
+
+## Recommended Entry Point
+
+Use [build.proj](build.proj) from the repository root:
+
+```bash
+dotnet build build.proj -t:<test_target> [optional_parameters]
+```
+
+Since `build.proj` is the only project file in the repo root, it can be omitted when building from
+the root:
+
+```bash
+dotnet build -t:<test_target> [optional_parameters]
+```
+
+The command-line examples below will assume that `build.proj` is selected by default and will omit
+it from the `dotnet build` command.
+
+Test targets build the projects they depend on, so a separate build step is not required for normal test runs.
+
+## Test Targets
+
+| Target                    | Description                                                                                                              |
+|---------------------------|--------------------------------------------------------------------------------------------------------------------------|
+| `Test`                    | Runs all test targets in the repository. This can take a long time and is not recommended for routine local development. |
+| `TestAbstractions`        | Runs Microsoft.Data.SqlClient.Extensions.Abstractions tests.                                                             |
+| `TestAzure`               | Runs Microsoft.Data.SqlClient.Extensions.Azure tests.                                                                    |
+| `TestSqlClient`           | Runs all Microsoft.Data.SqlClient test projects.                                                                         |

+
+```bash
+dotnet build -t:TestAzure -p:TestFilters=category!=failing
+```
+
+## Test Parameters
+
+The most commonly used test parameters are:
+
+| Parameter                   | Default                                                   | Description                                                                                                                   |
+|-----------------------------|-----------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------|
+| `-p:Configuration=`         | `Debug`                                                   | Build configuration. Use `Debug` or `Release`.                                                                                |
+| `-p:DotnetPath=`            | Empty                                                     | Path to the folder containing the `dotnet` binary. The path must end with `\` or `/`.                                         |
+| `-p:ReferenceType=`         | `Project`                                                 | For functional and manual SqlClient tests, use `Project` to test the source project or `Package` to test a package reference. |
+| `-p:TestBlameTimeout=`      | `10m`                                                     | Enables hang blame collection with the specified timeout. Use `0` to disable hang timeouts.                                   |
+| `-p:TestCodeCoverage=`      | `true`                                                    | Collects code coverage when set to `true`.                                                                                    |
+| `-p:TestFilters=`           | `category!=failing&category!=flaky&category!=interactive` | xUnit filter expression. Use `none` to run without the default filter.                                                        |
+| `-p:TestFramework=`         | Empty                                                     | Target framework to run. If omitted, all target frameworks supported by the project and host OS are run.                      |
+| `-p:TestResultsFolderPath=` | `test_results`                                            | Directory where test results are written.                                                                                     |
+| `-p:TestSet=`               | Empty                                                     | Selects manual test sets. Supported values include `1`, `2`, `3`, `AE`, and combinations such as `13` or `12AE`.              |
+
+## Test Filters
+
+`build.proj` passes `TestFilters` to `dotnet test --filter`. By default, tests marked with these categories are excluded:
+
+| Category      | Why it is excluded by default                                                       |
+|---------------|-------------------------------------------------------------------------------------|
+| `failing`     | Known failing tests.                                                                |
+| `flaky`       | Intermittently failing tests.                                                       |
+| `interactive` | Tests that require user interaction or external setup not suitable for normal runs. |
+
+Examples:
+
+Run a single test by fully-qualified name:
+
+```bash
+dotnet build -t:TestSqlClientUnit -p:TestFilters=FullyQualifiedName=Namespace.ClassName.MethodName
+```
+
+Run only flaky tests while investigating quarantine failures:
+
+```bash
+dotnet build -t:TestSqlClientManual -p:TestFilters=category=flaky
+```
+
+Disable the default filter:
+
+```bash
+dotnet build -t:TestSqlClientFunctional -p:TestFilters=none
+```
+
+When passing filter expressions that contain shell-sensitive characters such as `&`, quote or escape the value as
+required by your shell.
+
+## Running Test Projects Directly
+
+`build.proj` is the recommended entry point because it keeps logging, code coverage, package-reference mode, and
+common parameters consistent. For quick local investigation, you can run a test project directly:
+
+```bash
+dotnet test src/Microsoft.Data.SqlClient/tests/UnitTests/Microsoft.Data.SqlClient.UnitTests.csproj \
+  -p:Configuration=Debug \
+  --filter "category!=failing&category!=flaky&category!=interactive"
+```
+
+For manual tests, pass `TestSet` to the test project when needed:
+
+```bash
+dotnet test src/Microsoft.Data.SqlClient/tests/ManualTests/Microsoft.Data.SqlClient.ManualTests.csproj \
+  -p:Configuration=Debug \
+  -p:TestSet=2 \
+  --filter "category!=failing&category!=flaky&category!=interactive"
+```
+
+## Manual Test Prerequisites
+
+Manual tests require SQL Server or Azure SQL resources and a local test configuration file.
+
+For a basic local SQL Server run, prepare:
+
+- A SQL Server instance that the test machine can reach.
+- Shared Memory, TCP, and Named Pipes protocols enabled when testing local Windows SQL Server scenarios.
+- The `NORTHWIND` database created from [tools/testsql/createNorthwindDb.sql](tools/testsql/createNorthwindDb.sql). For
+  Azure SQL, use [tools/testsql/createNorthwindAzureDb.sql](tools/testsql/createNorthwindAzureDb.sql). Both scripts turn
+  `READ_COMMITTED_SNAPSHOT` and `ALLOW_SNAPSHOT_ISOLATION` off, which some transaction tests rely on. Azure SQL Database
+  enables `READ_COMMITTED_SNAPSHOT` by default, so run the script against the database rather than setting it up by hand.
+- The `UdtTestDb` database created from [tools/testsql/createUdtTestDb.sql](tools/testsql/createUdtTestDb.sql) if you
+  want UDT tests to run.
+- A login or integrated-security principal with permissions to create and drop the temporary objects used by the tests.
+
+Feature-specific tests require additional resources. If those resources are not configured, the corresponding
+conditional tests are skipped.
+
+## Manual Test Configuration
+
+Edit the source configuration file at `src/Microsoft.Data.SqlClient/tests/tools/Microsoft.Data.SqlClient.TestUtilities/
+config.jsonc`. The test utilities project copies that file to the test output directory, where the manual tests load it
+by default.
+
+The template file is:
+
+[src/Microsoft.Data.SqlClient/tests/tools/Microsoft.Data.SqlClient.TestUtilities/config.default.jsonc](src/Microsoft.Data.SqlClient/tests/tools/Microsoft.Data.SqlClient.TestUtilities/config.default.jsonc)
+
+`config.jsonc` is git-ignored. If it does not exist, the test utilities project copies `config.default.jsonc` to
+`config.jsonc` before compile. You can also create it manually:
+
+```bash
+cp src/Microsoft.Data.SqlClient/tests/tools/Microsoft.Data.SqlClient.TestUtilities/config.default.jsonc \
+  src/Microsoft.Data.SqlClient/tests/tools/Microsoft.Data.SqlClient.TestUtilities/config.jsonc
+```
+
+Update `config.jsonc` for your environment before running manual tests. The most important values for a basic run are `TCPConnectionString` and `NPConnectionString`.
+
+```jsonc
+{
+  "TCPConnectionString": "Data Source=tcp:localhost;Database=Northwind;Integrated Security=true;Encrypt=false;",
+  "NPConnectionString": "Data Source=np:localhost;Database=Northwind;Integrated Security=true;Encrypt=false;",
+  "EnclaveEnabled": false,
+  "TracingEnabled": false,
+  "SupportsEntraIntegrated": false,
+  "SupportsIntegratedSecurity": true
+}
+```
+
+For SQL Server in a Linux container, WSL, or another host where SQL authentication is easier than integrated security, use a TCP connection string like:
+
+```jsonc
+{
+  "TCPConnectionString": "Data Source=tcp:127.0.0.1;User Id=sa;Password=<password>;Database=Northwind;Encrypt=false;TrustServerCertificate=true"
+}
+```
+
+You can override the config file path with the `TEST_MDS_CONFIG` environment variable:
+
+```bash
+TEST_MDS_CONFIG=/path/to/config.jsonc dotnet build -t:TestSqlClientManual -p:TestSet=2
+```
+
+On PowerShell:
+
+```powershell
+$env:TEST_MDS_CONFIG = "C:\path\to\config.jsonc"
+dotnet build -t:TestSqlClientManual -p:TestSet=2
+```
+
+## Configuration Properties
+
+`SupportsEntraIntegrated` applies to Azure SQL Database, Azure SQL Managed Instance, and SQL Server
+2022 or later configured for Microsoft Entra authentication through Azure Arc.

+## Manual Test Sets
+
+The manual test project is split into compile-time sets so large runs can be parallelized.
+
+| TestSet | Coverage                                                                                                                                         |
+|---------|--------------------------------------------------------------------------------------------------------------------------------------------------|
+| `1`     | Smaller SQL connectivity and command scenarios.                                                                                                  |
+| `2`     | Broad data access coverage, including adapters, bulk copy, retry logic, data reader, schema, DNS caching, and related scenarios.                 |
+| `3`     | Additional integration coverage, including LocalDB, pooling, parameters, transactions, JSON, Kerberos, UDT, vector, and other SQL feature tests. |
+| `AE`    | Always Encrypted tests.                                                                                                                          |
+
+If `TestSet` is omitted, all sets are compiled and run. You can combine sets by concatenating values, for example
+`-p:TestSet=23` or `-p:TestSet=12AE`.
+
+## Results and Diagnostics
+
+Test results are written to the `test_results` directory by default. Override the location with
+`TestResultsFolderPath`:
+
+```bash
+dotnet build -t:TestSqlClientUnit -p:TestResultsFolderPath=/tmp/sqlclient-test-results
+```
+
+Hang blame collection is enabled by default with a `10m` timeout. To increase the timeout:
+
+```bash
+dotnet build -t:TestSqlClientManual -p:TestBlameTimeout=30m
+```
+
+To disable hang blame collection:
+
+```bash
+dotnet build -t:TestSqlClientManual -p:TestBlameTimeout=0
+```
+
+Code coverage is enabled by default. To disable it for a faster local run:
+
+```bash
+dotnet build -t:TestSqlClientUnit -p:TestCodeCoverage=false
+```

+      Description:    When set, redirects each project's binary output (bin) to an isolated
+                      location instead of the repo's artifacts/ folder, and forces a full
+                      (non-incremental) compile. This lets a build run at any time without
+                      clobbering existing real build output - for example, an analysis pass that
+                      only needs to compile the code and must not disturb a real build's output.
+
+                      * bin is redirected under "$(IsolatedBuildPath)/bin/" via ArtifactPath. Each
+                        project's OutputPath already appends a project-specific subfolder, so the
+                        projects do not collide and the real artifacts/ folder is left untouched.
+                      * The intermediate (obj) directory is intentionally left at its default,
+                        per-project location. MSBuild resolves the default relative obj/ against
+                        each project's own directory, which keeps intermediates separate for the
+                        multiple projects that make up a package (for example the ref, src, and
+                        notsupported projects of the driver). Pointing every project at a single
+                        shared obj/ under the isolated path makes those projects overwrite each
+                        other's restore assets and fail. The non-incremental switch guarantees a
+                        full recompile regardless of any pre-existing intermediate output.
+
+                      NOTE: Even though an isolated build shares the default obj/ with a prior real
+                      build, it does not perturb that real build's output. The non-incremental switch
+                      does not run Clean or delete anything; it disables the incremental/up-to-date
+                      checks and forces a full recompile so the analyzers see every source file. Real
+                      output is safe because bin is redirected to $(IsolatedBuildPath): the isolated
+                      build only ever writes to the isolated bin, never to the real artifacts/ bin.
+                      The recompile just rewrites the shared obj/ intermediates, which is harmless
+                      because nothing downstream consumes obj/.
+      Default value:  [blank] (normal artifacts/ location and incremental build are used)

+      "category!=x" matches everything and "category=x" matches nothing.  Trait *values* are always
+      compared case-insensitively, so only the key casing is dangerous.
+
+      The failure is per-assembly, which is why it hid for so long: it only surfaces when no test in
+      that assembly declares a lower-case "category" key.  Microsoft.DotNet.XUnitExtensions injects
+      one via [ActiveIssue], [OuterLoop], [PlatformSpecific] and friends, which masked the problem
+      in most of our test assemblies until Azure.Test - which uses none of those attributes - ran
+      its excluded "interactive" test in CI.

+- **Merge conflicts**:
+  - *Before review has started*: Rebase your branch against the latest `main` branch to keep history clean.
+  - *After a reviewer has started reviewing*: Do **not** rebase. Rebasing rewrites commit history and makes it impossible for reviewers to tell which commits they have already reviewed, forcing them to start over. Instead, resolve conflicts by merging the latest `main` into your branch (`git merge main`) so that previously reviewed commits remain intact and reviewers can pick up where they left off.

+## Tracking PRs in the GitHub Project
+
+The [SqlClient Board](https://github.com/orgs/dotnet/projects/588) (dotnet org project #588) is the team's triage board for tracking issues and PRs. When a PR is linked to an issue, its progress is tracked through the project's fields described below.
+
+### Project Fields
+
+| Field | Type | Values | Purpose |
+|-------|------|--------|---------|
+| **Status** | Single select | `To triage`, `Waiting for customer`, `In progress`, `In review`, `In validation`, `Done` | Tracks the current workflow stage of the item |
+| **Priority** | Single select | `P0`, `P1`, `P2`, `P3` | Indicates urgency and scheduling priority |
+| **Size** | Single select | `XS`, `S`, `M`, `L`, `XL` | Estimates effort/complexity of the work |
+| **API Impact** | Single select | `Breaking Change`, `New API`, `None` | Flags whether the change affects public API surface |
+| **PM Approved** | Single select | `N/A`, `Pending`, `Approved` | Tracks product manager sign-off for API or behavioral changes |
+| **Assignees** | Field | *(GitHub users)* | Who is responsible for the work |
+| **Labels** | Field | *(GitHub labels)* | Categorization and area tags |
+| **Reviewers** | Field | *(GitHub users)* | Assigned code reviewers |
+| **Milestone** | Field | *(GitHub milestones)* | Target release version |
+| **Linked pull requests** | Field | *(PR references)* | PRs associated with the issue |
+| **Parent issue** | Field | *(issue reference)* | Epic or parent tracking issue |
+| **Sub-issues progress** | Field | *(auto-calculated)* | Completion progress of child issues |
+| **Comment** | Text | *(free text)* | Additional context or notes |
+| **AB-Link** | Text | *(URL)* | Link to Azure Boards work item (if applicable) |
+
+### Status Stages for PRs
+
+PRs (and their linked issues) move through the **Status** field to communicate reviewability and progress:
+
+| Status | What it means for a PR |
+|--------|------------------------|
+| **To triage** | PR just opened or linked issue is awaiting initial assessment. Maintainers will review scope, assign reviewers, and set priority. |
+| **In progress** | Author is actively developing the change. PR may be in Draft state. |
+| **In review** | PR is ready for code review. Reviewers are assigned and the author considers the implementation complete. |
+| **Waiting for customer** | Review feedback has been given; the PR author needs to respond or push changes. When a reviewer requests changes, they will also apply the **`Author attention needed`** label so the PR is easy to surface in queries and dashboards. Once the author addresses the feedback, they should remove the `Author attention needed` label if permissions allow or comment `/ready` on the PR to remove the label `Author attention needed` and re-engage the reviewers to move the PR back to `In review`. |
+| **In validation** | PR is approved and being validated (CI, manual testing, integration checks) before merge. |
+| **Done** | PR has been merged and the associated work is complete. |
+
+### Status Transitions
+
+When a reviewer leaves feedback that needs author action, they move the PR to `Waiting for customer` **and** apply the `Author attention needed` label. The author removes the label (and updates Status back to `In review`/`In progress`) once the feedback is addressed.

+
+### Additional Field Usage
+
+- **Priority**: `P0` items are critical fixes that should be reviewed and merged urgently. `P1` items are high priority for the current milestone. `P2`/`P3` items are scheduled as capacity allows.
+- **Size**: Helps reviewers estimate review effort. `XS`/`S` PRs should get faster turnaround. `L`/`XL` PRs may need multiple reviewers or phased review.
+- **API Impact**: PRs marked `Breaking Change` or `New API` require **PM Approved = Approved** before merge. `ref/` project updates must accompany these PRs.
+- **PM Approved**: Set to `Pending` when a PR introduces API changes. Must reach `Approved` before the PR can be merged. `N/A` for internal or non-API changes.
+
+### Guidelines for Contributors
+
+> **Note:** Setting labels and project board fields (Status, Priority, etc.) requires maintainer or triage access. External contributors cannot modify these directly. Instead, suggest labels in your PR description and the team will apply them. If review feedback asks you to "remove the label" or "update Status", a maintainer will handle it if you don't have access—just let the team know in a comment.
+
+1. **Link your PR to an issue** — This ensures the PR appears on the project board and is tracked through the workflow.
+2. **Keep Status current** — If you're the author, move your linked issue to `In review` when your PR is ready for feedback.
+3. **Respond promptly** — When status is `Waiting for customer` and the **`Author attention needed`** label is applied, the team is blocked on your response. Address the feedback, push the updates, **remove the `Author attention needed` label**, and move Status back to `In review` (or `In progress` for major rework) so reviewers know the PR is ready for another pass. If you are a community contributor, you may post a comment `/ready` on the PR to automate removing the label and re-engaging reviewers on the PR.
+4. **Flag API changes early** — Set **API Impact** appropriately so PM review can happen in parallel with code review.
+5. **Don't skip validation** — Even after approval, the PR stays in `In validation` until CI passes and any manual verification is complete.
+
+### Guidelines for Reviewers
+
+1. **Signal that author action is required** — When your review requests changes (whether via formal "Request changes" or a comment that requires author follow-up), apply the **`Author attention needed`** label to the PR and move its linked issue to `Waiting for customer`. This pair (label + status) is what the team uses to find PRs that are blocked on the author versus those still awaiting review.
+2. **Don't remove the label yourself** — Leave the `Author attention needed` label in place until the author pushes updates addressing the feedback; the author is responsible for removing it when they hand the PR back for review.
+3. **Re-review promptly** — Once the author removes the label, the PR status should be updated either by Author (if they have permissions) or the reviewer to `In review`, so it doesn't stall and is picked up for review on time.
+4. **Only reviewers resolve their own feedback threads** — A review comment thread should only be resolved by the reviewer who created it, once they are satisfied the feedback has been addressed. Authors should not resolve reviewer threads themselves.

-# AzureAuthentication Sample App
-
-A minimal console application that verifies **SqlClient** can connect to a SQL Server using Entra ID
-authentication (formerly Azure Active Directory authentication) via the **Azure** package. It also
-references the **Azure Key Vault Provider** package to confirm there are no transitive dependency
-conflicts between the packages.
-
-The following SqlClient packages are used, either directly or transitively:
-
-- `Microsoft.Data.SqlClient`
-- `Microsoft.SqlServer.Server`
-- `Microsoft.Data.SqlClient.Internal.Logging`
-- `Microsoft.Data.SqlClient.Extensions.Abstractions`
-- `Microsoft.Data.SqlClient.Extensions.Azure`
-- `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`
-
-## Purpose
-
-This app serves as a smoke test for package compatibility. It:
-
-1. Instantiates `SqlColumnEncryptionAzureKeyVaultProvider` to ensure the AKV provider assembly loads
-   without conflicts.
-2. Opens a `SqlConnection` using a connection string you provide, validating that authentication and
-   connectivity work end-to-end.
-
-The app is designed to run against both **published NuGet packages** and **locally-built packages**
-(via the `packages/` directory configured in `NuGet.config`).
-
-## Build Parameters
-
-Package versions are controlled through MSBuild properties. Pass them on the command line with `-p:`
-(or `/p:`) to override the defaults defined in `Directory.Packages.props`.
-
-| Property | Default | Description |
-| --- | --- | --- |
-| `SqlClientVersion` | `7.0.0-preview4.26064.3` | Version of `Microsoft.Data.SqlClient` to reference. |
-| `AkvProviderVersion` | `7.0.0-preview1.26064.3` | Version of `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider` to reference. |
-| `AzureVersion` | None | Version of `Microsoft.Data.SqlClient.Extensions.Azure` to reference.  When omitted, the `Azure` package will not be referenced. |
-
-## Local Package Source
-
-The `NuGet.config` adds a `packages/` directory as a local package source. To test against packages
-that haven't been published to NuGet yet, copy the `.nupkg` files into this folder and specify the
-matching version via the build properties above.
-
-NuGet will cache copies of the packages it finds in `packages/` after a successful restore.  If you
-update the `.nupkg` files in `packages/` without incrementing their version numbers (and referencing
-those new version numbers) you will have to clear the NuGet caches in order for the next restore
-operation to pick them up:
-
-```bash
-dotnet nuget locals all --clear
-```
-
-## Running the App
-
-The app has built-in help:
-
-```bash

-Description:
-  Azure Authentication Tester
-  ---------------------------
-
-  Validates SqlClient connectivity using EntraID (formerly Azure Active Directory) authentication.
-  Connects to SQL Server using the supplied connection string, which must specify the authentication method.
-
-  Supply specific package versions when building to test different versions of the SqlClient suite, for example:
-
-    -p:SqlClientVersion=7.0.0.preview4
-    -p:AkvProviderVersion=7.0.1-preview2
-    -p:AzureVersion=1.0.0-preview1
-
-Usage:
-  AzureAuthentication [options]
-
-Options:
-  -c, --connection-string <connection-string> (REQUIRED)  The ADO.NET connection string used to connect to SQL Server.
-                                                          Supports SQL, Entra ID, and integrated authentication modes.
-  -l, --log-events                                        Enable SqlClient event emission to the console.
-  -t, --trace                                             Pauses execution to allow dotnet-trace to be attached.
-  -v, --verbose                                           Enable verbose output with detailed error information.
-  -?, -h, --help                                          Show help and usage information
-  --version                                               Show version information
-```
-
-The app expects a single argument: a full connection string.
-
-```bash
-dotnet run -- -c "<connection string>"
-```
-
-For Entra ID authentication, use an `Authentication` keyword in the connection string. For example:
-
-```bash
-dotnet run -- -c "Server=myserver.database.windows.net;Database=mydb;Authentication=ActiveDirectoryDefault"
-```
-
-On success the app emits to standard out:
-
-```bash
-Azure Authentication Tester
----------------------------
-
-Packages used:
-  SqlClient:     7.0.0-preview4.26055.1
-  AKV Provider:  6.1.2
-  Azure:         1.0.0-preview1.26055.1
-
-Connection details:
-  Data Source:      adotest.database.windows.net
-  Initial Catalog:  Northwind
-  Authentication:   ActiveDirectoryPassword
-
-Testing connectivity...
-Connected successfully!
-    Server version: 12.00.1017
-```
-
-Errors will be emitted to standard error:
-
-```bash
-Testing connectivity...
-Connection failed:
-  Cannot find an authentication provider for 'ActiveDirectoryPassword'.
-```
-
-### Examples
-
-Run with the default (published) package versions, and no `Azure` package:
-
-```bash
-dotnet run -- -c "<connection string>"
-```
-
-If the connection string specifies one of the Entra ID authentication methods,
-`SqlClient` will fail with an error indicating that no authentication provider has been registered.
-This is because the `Azure` package was not referenced, and the app did not provide its own custom
-authentication provider.
-
-Run against locally-built packages (drop `.nupkg` files into the `packages/` folder first):
-
-```bash
-dotnet run -p:SqlClientVersion=7.0.0-preview4 -- -c "<connection string>"
-```
-
-Run including the `Azure` extensions package:
-
-```bash
-dotnet run -p:AzureVersion=1.0.0-preview1 -- -c "<connection string>"
-```
-
-Override all three versions at once:
-
-```bash
-dotnet run -p:SqlClientVersion=7.0.0-preview1 -p:AkvProviderVersion=7.0.0-preview1 -p:AzureVersion=1.0.0-preview1 -- -c "<connection string>"
-```
-
-## Prerequisites
-
-- [.NET 10.0 SDK](https://dotnet.microsoft.com/download) and .NET Framework 4.8.1 or later.
-- A SQL Server or Azure SQL instance accessible with Entra ID credentials.
-- Azure credentials available to `DefaultAzureCredential` (e.g. Azure CLI login, environment
-  variables, or managed identity).

+# Azure SQL Connector (WinForms)
+
+A small Windows Forms test application that lets a user fill in Azure SQL Database connection
+parameters in a UI, builds the corresponding ADO.NET connection string via
+`SqlConnectionStringBuilder`, and tests connectivity using `Microsoft.Data.SqlClient`.
+
+It is intended as a quick, repeatable scratch tool for manually validating connection-string
+combinations (server / database / authentication mode / encryption / etc.) against an Azure SQL DB
+or SQL Server instance, **and as a manual repro** for the WAM-broker behavior added in this
+branch's `ActiveDirectoryAuthenticationProvider`.
+
+The sample multi-targets:
+
+| TFM              | Purpose                                                                                          |
+| ---------------- | ------------------------------------------------------------------------------------------------ |
+| `net481`         | Exercises the legacy `SetIWin32WindowFunc` API used by .NET Framework callers with WinForms.     |
+| `net10.0-windows` | Exercises the modern `SetParentActivityOrWindowFunc` API used on .NET 8+.                       |
+
+`net10.0-windows` restores and builds cleanly on Linux/macOS hosts even though the resulting
+binary only runs on Windows, so the project no longer needs a separate no-op cross-platform
+fallback.
+
+> **Note:** `SetParentActivityOrWindowFunc` is also available on `net481` and is the
+> recommended API for new code on any framework. The sample wires `net481` up to
+> `SetIWin32WindowFunc` only to keep coverage of that legacy code path; replacing the
+> `SetIWin32WindowFunc(() => this)` call with `SetParentActivityOrWindowFunc(() => this.Handle)`
+> on `net481` works the same way.
+
+## Mode selector
+
+When the app launches it shows a small `ModeSelectorForm` that picks between two top-level forms:
+
+| Mode                               | Form              | What it exercises                                                                                                       |
+| ---------------------------------- | ----------------- | ----------------------------------------------------------------------------------------------------------------------- |
+| **UI thread (`OpenAsync`)**        | `MainForm`        | Calls `SqlConnection.OpenAsync()` on the UI thread so the Windows Forms message pump stays alive during MSAL sign-in.   |
+| **Worker thread (`Open`, sync)**   | `MainFormWorker`  | Calls `SqlConnection.Open()` on a background worker thread; the parent window handle is captured up-front on the UI thread. |
+
+Both forms demonstrate the supported patterns for parenting the WAM broker (or the legacy
+embedded WebView on .NET Framework).
+
+## Form inputs
+
+| Field                      | Maps to connection string keyword               |
+| -------------------------- | ----------------------------------------------- |
+| Server name                | `Data Source`                                   |
+| Database name              | `Initial Catalog` *(only added when non-empty)* |
+| Authentication             | `Authentication` *(SqlAuthenticationMethod)*    |
+| User ID                    | `User ID`                                       |
+| Password                   | `Password`                                      |
+| Encrypt                    | `Encrypt` *(Mandatory / Optional / Strict)*     |
+| Trust server certificate   | `TrustServerCertificate`                        |
+| Connect timeout (s)        | `Connect Timeout`                               |
+
+The **Authentication** dropdown is populated from every member of
+`Microsoft.Data.SqlClient.SqlAuthenticationMethod`. The User ID and Password fields are enabled /
+disabled automatically based on the selected method:
+
+- **SqlPassword** / **ActiveDirectoryPassword** — both User ID and Password are required.
+- **ActiveDirectoryServicePrincipal** — User ID = App (Client) ID, Password = client secret.
+- **ActiveDirectoryManagedIdentity / MSI / Default / Interactive / DeviceCodeFlow / WorkloadIdentity**
+  — User ID is optional (e.g. user-assigned MI client id), Password is disabled.
+- **ActiveDirectoryIntegrated** — credentials come from the OS, both fields disabled.
+
+## Buttons
+
+| Button                  | Action                                                                 |
+| ----------------------- | ---------------------------------------------------------------------- |
+| Build Connection String | Builds the connection string from the form values and displays it.    |
+| Test Connection         | Builds the connection string and opens the connection.                |
+| Copy to Clipboard       | Copies the currently-built connection string to the clipboard.        |
+| Clear All               | Resets every input field to its default state.                         |
+| Who Am I?               | Connects and runs an identity query (`SUSER_SNAME()`, `ORIGINAL_LOGIN()`, `USER_NAME()`, `DB_NAME()`, `@@SPID`, etc.) and prints the results. |
+
+The result pane shows the built connection string with the password masked, the test connection
+outcome (including SQL error number when applicable), and the server version on success.
+
+## Prerequisites
+
+- Visual Studio 2026 (or any IDE / SDK with .NET Framework **4.8.1** Developer Pack installed) for
+  the `net481` target. The `net10.0-windows` target only needs the .NET 10 SDK.
+- Network connectivity to your Azure SQL Database (server firewall must allow your client IP).
+- For Entra ID authentication modes, valid credentials available through Azure CLI / environment
+  variables / managed identity / the WAM broker, depending on the chosen method.
+
+## Build & run
+
+From the project folder:
+
+```pwsh
+dotnet build .\AzureSqlConnector.csproj
+dotnet run --project .\AzureSqlConnector.csproj -f net10.0-windows   # modern WAM API
+dotnet run --project .\AzureSqlConnector.csproj -f net481            # legacy IWin32Window API
+```
+
+Or load `src\Microsoft.Data.SqlClient.slnx` in Visual Studio, set **AzureSqlConnector** as the
+startup project, and press **F5**.
+
+## Example
+
+1. **Server name:** `myserver.database.windows.net`
+2. **Database name:** `MyDb`
+3. **Authentication:** `SqlPassword`
+4. **User ID:** `sqladmin`
+5. **Password:** *your password*
+6. **Encrypt:** `Mandatory`
+7. **Trust server certificate:** unchecked
+8. Click **Test Connection** — the result pane should display
+   `Connected successfully! Server version: 12.00.xxxx`.
+
+## Entra ID parent-window plumbing
+
+For any `ActiveDirectory*` authentication method (especially **ActiveDirectoryInteractive**) the
+app installs an `ActiveDirectoryAuthenticationProvider` and tells it which window should host the
+sign-in UI:
+
+- On **`net481`** the form calls `provider.SetIWin32WindowFunc(() => this)`. This is the legacy
+  API used by .NET Framework callers with the embedded WebView.
+- On **`net10.0-windows`** the form calls
+  `provider.SetParentActivityOrWindowFunc(() => this.Handle)`. This is the modern API that also
+  integrates with the WAM broker on Windows.
+
+The provider is registered for every `SqlAuthenticationMethod.ActiveDirectory*` value at startup.
+
+### Threading patterns
+
+| Form              | Open mode                | Parent window callback                                                                                                                          |
+| ----------------- | ------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------- |
+| `MainForm`        | `OpenAsync` on UI thread | Callback runs on the UI thread when MSAL invokes it, so `this`/`this.Handle` is naturally safe to access.                                       |
+| `MainFormWorker`  | `Open` (sync) on worker  | The form captures `this.Handle` into a field on the UI thread before kicking off the worker; the callback closes over that captured value so it never needs to marshal back. |
+
+Without one of these patterns the WAM broker (or the embedded WebView on .NET Framework) can fail
+to render or stay unresponsive while it waits for the user.
+

+what the existing test suite does and does not actually verify.
+
+---
+
+## 1. Background: two ways a connection can be "in" a transaction
+
+This distinction is the crux of the entire bug.
+
+When a connection participates in a `TransactionScope`, it ends up in one of **two
+distinct** states. They overlap, but neither implies the other.
+
+### Delegated root — "I *own* this transaction"
+
+Only one connection is involved, so `System.Transactions` delegates the transaction
+down to SQL Server rather than paying for a distributed coordinator. The transaction
+lives **on** the connection.
+
+- `IsTransactionRoot` → `true`
+- `EnlistedTransaction` → set at first, then **cleared** later (see below)
+
+`IsTransactionRoot` is not a stored flag. It is derived:
+
+```csharp
+internal bool IsTransactionRoot => DelegatedTransaction?.IsActive == true;
+```
+
+Enlistment sets `EnlistedTransaction` unconditionally, so a *freshly* delegated root
+has both. But once the transaction is no longer `Active`,
+`DbConnectionInternal.DetachCurrentTransactionIfEnded` clears `EnlistedTransaction`:
+
+```csharp
+transactionIsDead = enlistedTransaction.TransactionInformation.Status != TransactionStatus.Active;
+if (transactionIsDead) { DetachTransaction(enlistedTransaction, true); }
+```
+
+The delegated transaction, meanwhile, can still report `IsActive == true`. That
+transient **half-state** — root, but no `EnlistedTransaction` — is precisely the state
+issue #4001 reproduces in.
+
+### Enlisted participant — "I *joined* someone else's transaction"
+
+Multiple resources are involved, so a coordinator (MSDTC) owns the transaction and
+each connection enlists in it.
+
+- `IsTransactionRoot` → `false`
+- `EnlistedTransaction` → set
+
+### The trap
+
+Neither field subsumes the other: a delegated root can have a `null`
+`EnlistedTransaction`, and an enlisted participant is never a root. Any check that
+tests only one of these fields silently misses the other case — and does so with no
+exception at the point of the mistake.
+
+---
+
+## 2. Where the damage occurs
+
+When a connection is closed it returns to the pool and is **reset** — wiped clean for
+the next consumer. If a transaction is still in flight, that reset must *preserve* it.
+The entire decision is one boolean:
+
+```csharp
+_parser.PrepareResetConnection(preserveTransaction);
+```
+
+Pass `false` while a transaction is genuinely live, and the TDS reset destroys the
+server-side transaction **while `System.Transactions` still believes it exists**.
+
+The failure then surfaces later, some distance from the cause:
+
+1. `TransactionScope` disposes and rolls back.
+2. `SqlDelegatedTransaction.Rollback` asks the server to roll back a transaction the
+   server no longer has.
+3. The rollback fails, and SqlClient calls `DoomThisConnection()`.
+4. The physical connection is now permanently marked broken.
+5. With a small pool (the report used `MaxPoolSize=1`) that same doomed connection is
+   immediately handed back out.
+6. The next caller gets:
+
+> `InvalidOperationException: The requested operation cannot be completed because the connection has been broken.`
+
+The exception names the connection, not the reset that ruined it. That distance
+between cause and symptom is what makes this class of bug hard to trace.
+
+---
+
+## 3. What PR #3019 actually changed
+
+The relevant diff from `0322d44c7`:
+
+```diff
+- _parser.PrepareResetConnection(IsTransactionRoot && !IsNonPoolableTransactionRoot);
++ _parser.PrepareResetConnection(EnlistedTransaction is not null && Pool is not null);
+```
+
+The old helper was:
+
+```csharp
+internal protected override bool IsNonPoolableTransactionRoot
+    => IsTransactionRoot && (!Is2008OrNewer || Pool == null);
+```
+
+Substituting, the pre-#3019 condition was:
+
+```csharp
+IsTransactionRoot && Is2008OrNewer && Pool != null
+```
+
+The `Is2008OrNewer` term is **deliberately not carried forward**, for two reasons.
+
+First, it is outside the support matrix. The term is `false` for exactly one server
+version — SQL Server 2005 — and the driver's supported floor is SQL Server 2012.
+
+Second, and more importantly, **it was never safe on its own.** `IsNonPoolableTransactionRoot`
+had two jobs, not one. Besides suppressing the preserve bit, it also drove pool routing:
+`DbConnectionPool` sent any connection it flagged into *stasis* rather than back into the
+pool. Being parked is what made a plain reset harmless — the connection was never handed
+to another caller. #3019 deleted the property entirely, and today's pools route on
+`EnlistedTransaction` alone. A delegated root with a `null` `EnlistedTransaction` now goes
+straight back to the **general** pool.
+
+Reinstating only the suppression half would therefore reset a live delegated transaction
+*and* hand the connection out again — #4001 exactly, just narrowed to SQL Server 2005.
+Half of a retired safety mechanism is worse than none of it.
+
+So the two conditions were:
+
+| | Question it asked | Covered | Missed |
+|---|---|---|---|
+| **Pre-#3019** | "Am I the *owner*?" | delegated root | enlisted → **#2970** |
+| **#3019** | "Am I *enlisted*?" | enlisted | delegated root → **#4001** |
+
+**#3019 swapped one case for the other rather than covering both.** It genuinely fixed
+#2970, and it traded it for #4001. Both conditions were half-right; neither was wrong
+about the case it did cover.
+
+This reframes the fix: the goal is not to undo #3019, it is to finish it.
+
+---
+
+## 4. The fix
+
+The predicate is extracted into a helper so it can be tested directly:
+
+```csharp
+internal static bool ShouldPreserveTransactionOnReset(
+    bool isPooled,
+    bool isTransactionRoot,
+    bool hasEnlistedTransaction)
+{
+    if (!isPooled)
+    {
+        return false;
+    }
+
+    return isTransactionRoot || hasEnlistedTransaction;
+}
+```
+
+This is `OLD || NEW`: each arm answers one of the two questions from section 1, so the
+predicate is `true` wherever either predecessor was.
+
+---
+
+## 5. Why this cannot reintroduce #2970
+
+This is the question that matters most, and it is answerable by inspection rather than
+by testing. Every reachable state, for a pooled connection:
+
+| `IsTransactionRoot` | `EnlistedTransaction` | Pre-#3019 | #3019 | **This fix** |
+|:---:|:---:|:---:|:---:|:---:|
+| `false` | `null` | `false` | `false` | `false` |
+| **`true`** | **`null`** | ✅ `true` | ❌ `false` ← **#4001** | ✅ **`true`** |
+| **`false`** | **set** | ❌ `false` ← **#2970** | ✅ `true` | ✅ **`true`** |
+| `true` | set | `true` | `true` | `true` |
+
+Read the **#2970 row**. That is the row PR #3019 was created to fix, and this fix still
+evaluates `true` there. It is untouched.
+
+Reintroducing #2970 would require that cell to flip to `false`, and `A || B` cannot
+evaluate `false` while `B` is `true`. The guarantee is structural, not empirical.
+
+Because each arm reproduces its original predecessor exactly, the condition returns
+`true` wherever either predecessor did, and never returns `false` where one of them
+returned `true`.
+
+---
+
+## 6. How the root cause was established
+
+The cause was **proven at runtime, not inferred**. The driver was temporarily
+instrumented at the reset site and at `DoomThisConnection()`. The captured state at the
+critical reset:
+
+```
+[RESET] obj=4  preserve=False  root=False  deleg=null         enlisted=null  pool=set
+[RESET] obj=7  preserve=False  root=False  deleg=null         enlisted=null  pool=set
+[RESET] obj=7  preserve=False  root=True   deleg=active=True  enlisted=null  pool=set   <-- old: true, new: false
+[DOOM]  obj=7
+   at Microsoft.Data.SqlClient.SqlDelegatedTransaction.Rollback(...)
+   at System.Transactions.Transaction.Rollback()
+   at System.Transactions.TransactionScope.InternalDispose()
+   at System.Transactions.TransactionScope.Dispose()
+[FAIL] Bug reproduced
+```
+
+The third reset is the bug caught in the act: `root=True`, `deleg.IsActive=True`,
+`enlisted=null`, and `preserve=False`. A live delegated transaction being discarded.
+
+This mattered, because **the initial hypothesis was wrong.** The first theory was that
+#3019 had made the condition *too broad*, and a narrowing fix was written on that
+basis. It did not work. The instrumentation showed the opposite — #3019 had *narrowed*
+the condition, not widened it — and the fix was rewritten accordingly. Without runtime
+evidence this would have been fixed in the wrong direction.
+
+All instrumentation was removed before commit.
+
+---
+
+## 7. What the existing tests actually verify
+
+This section is deliberately blunt, because the intuitive answer is wrong.
+
+### Bisection
+
+Against the reporter's reproduction (NHibernate 5.5.2, `MaxPoolSize=1`,
+`TransactionScope` with a failed DTC promotion):
+
+**6.0.5 ✅ · 6.1.0 ❌ · 6.1.1 ❌ · 6.1.4 ❌ · `main` ❌**
+
+This places the regression in the 6.1.0 window, consistent with #3019.
+
+### Both pool implementations, both directions
+
+| | without fix | with fix |
+|---|---|---|
+| `WaitHandleDbConnectionPool` (default) | ❌ reproduces | ✅ passes |
+| `ChannelDbConnectionPool` (`UseConnectionPoolV2`) | ❌ reproduces | ✅ passes |
+
+The **left-hand column is the load-bearing one.** It was produced by stashing the fix
+and rebuilding. Without it, a pass on the V2 pool could simply mean V2 never reaches
+this code path, which would prove nothing.
+
+(V2 in released 6.1.4 throws `NotImplementedException`, so only `main` was testable.)
+
+### Mutation testing of the manual suite
+
+`--filter "FullyQualifiedName~TransactionTest"` reports **9/9 passing** with the fix.
+That number is easy to over-read, so the suite was mutation-tested: the condition was
+replaced with each known-buggy variant and the suite re-run.
+
+| Condition compiled in | Bug it contains | Suite result |
+|---|---|---|
+| Pre-#3019 (`IsTransactionRoot && Pool is not null`) | **#2970** | **9/9 passed** |
+| #3019 (`EnlistedTransaction is not null && Pool is not null`) | **#4001** | **9/9 passed** |
+| This fix (union) | none | 9/9 passed |
+
+**The suite passes on all three.** It does not detect either bug, and therefore does
+not guard this line at all in this environment.
+
+`Test_EnlistedTransactionPreservedWhilePooled` — the test added by #3019 specifically
+to cover #2970 — is tagged `[Trait("Category", "flaky")]` and passes against code that
+carries the #2970 bug.
+
+The practical conclusion: **the 9/9 result is evidence of no collateral damage, not
+evidence that the fix works.**
+
+### The regression test that was added
+
+An end-to-end reproduction was attempted extensively and abandoned. The `#4001` state
+requires a narrow simultaneity — the transaction's status already non-`Active` (so
+`DetachCurrentTransactionIfEnded` has cleared `EnlistedTransaction`) while
+`DelegatedTransaction.IsActive` is still `true` — and which of two teardown paths in
+`SqlDelegatedTransaction` wins is a race:
+
+- `TransactionEnded` sets `_active = false` and *immediately* calls
+  `DoomThisConnection()`. If this path runs first, the delegate is already inactive
+  before any reset, so the state is never observed.
+- `Rollback`, driven from `TransactionScope.Dispose`, sets `_active = false` *after* the
+  reset. This is the ordering the reporter hit.
+
+Roughly twenty harness variants — varying pool size, pool implementation, promotion
+success, explicit rollback, and parking the delegate in the transacted pool ahead of the
+enlistment — consistently drove the first path. A test built on that race would be
+flaky, which is the same defect `Test_EnlistedTransactionPreservedWhilePooled` already
+demonstrates.
+
+Instead the predicate was extracted into
+`SqlConnectionInternal.ShouldPreserveTransactionOnReset` and pinned directly by
+`SqlConnectionInternalResetTransactionTests`, following the existing precedent of
+`ResolveLoginTimeout` / `SqlConnectionInternalTimeoutTests`. The tests were themselves
+mutation-tested:
+
+| Condition compiled into the helper | Bug it contains | New tests |
+|---|---|---|
+| `hasEnlistedTransaction` (#3019) | **#4001** | ❌ 1 failed |
+| `isTransactionRoot` (pre-#3019) | **#2970** | ❌ 1 failed |
+| The shipped condition | none | ✅ 8 passed |
+
+This satisfies "fails before the change, passes after" for **both** regressions, and
+does so deterministically and without a server.
+
+---
+
+## 8. Related
+
+- **#2970** — the issue #3019 was fixing. Fully preserved by this change (section 5).
+- **#2285** — reports the same exception with no reproduction. Plausibly the same root
+  cause, though unconfirmed.

+    This is an ultra-hack. We have a lot of files in the /eng/pipelines directory, and it would be
+    nice to manage these inside an IDE. However, MSBuild doesn't have a good solution for including
+    recursive folder trees of non-compilable files, with the only solution to be manually adding
+    each file as a linked file in the solution. This is a terrible situation because it means each
+    time a file is added or removed from this folder, it must be manually updated in the solution.
+    It is also the case that most engineers forget to do this step, and it comes down to more
+    diligent engineers to keep the pipelines folder up to date. Well, the diligent engineers have
+    had enough and are tired of doing it.
+
+    So, this project was added as a way to automatically keep the pipelines directory up-to-date in
+    the solution. It is *not built* in any configuration, and exists purely to collect all files
+    under the /eng/pipelines folder.
+
+    No changes should be made to this project, perhaps updating the TargetFramework property if
+    the framework specified goes out of support.

+.SYNOPSIS
+    Stages SqlClient driver packages and exposes their exact versions to Azure Pipelines.
+
+.DESCRIPTION
+    Copies the .nupkg and .snupkg files downloaded from an upstream SqlClient package artifact into
+    a local NuGet feed. It resolves package versions from the .nupkg filenames, verifies that all
+    required SqlClient-family packages share one version, and emits Azure Pipelines logging commands
+    that create these job-scoped variables for downstream tasks:
+
+      sqlClientPackageVersion  SqlClient family
+      sqlServerPackageVersion  Microsoft.SqlServer.Server
+
+    Every required .nupkg must be present in ArtifactDirectory. Symbol packages are optional. The
+    script stops on missing required packages, copy failures, and ambiguous filesystem errors.
+
+.PARAMETER FeedPath
+    Directory used as the local NuGet feed. The script creates it when it does not exist and
+    overwrites packages with matching filenames.
+
+.PARAMETER ArtifactDirectory
+    Directory containing the .nupkg files downloaded from the upstream pipeline artifact. Optional
+    .snupkg files in this directory are copied when present.
+
+.EXAMPLE
+    ./download-driver-packages.ps1 `
+        -FeedPath 'C:\agent\_work\1\s\packages' `
+        -ArtifactDirectory 'C:\agent\_work\1\sqlclient-ci-package\SqlClient-Driver-Packages'
+
+    Stages all driver packages and resolves every version from its package filename.
+
+.OUTPUTS
+    None. Results are emitted as Azure Pipelines task.setvariable logging commands.
+
+.NOTES
+    This script is designed for PowerShell Core in Azure Pipelines. Package filenames must use the
+    conventional <package-id>.<version>.nupkg format, and versions must begin with a digit.

+    Computes effective SqlClient and SqlServer package and file versions for OneBranch builds.
+
+.DESCRIPTION
+    Evaluates the canonical version properties through the GetVersionsSqlClient and
+    GetVersionsSqlServer targets in build.proj, selects the versions that the current pipeline run
+    should consume, and publishes those values as Azure DevOps job output variables.
+
+    The SqlClient family always uses SqlClientNextVersion. Microsoft.SqlServer.Server uses
+    SqlServerNextVersion when BuildSqlServer is true and SqlServerPublishedVersion when it is false.
+    The published SqlServer version is needed when SqlServer is not built because downstream
+    SqlClient projects restore that existing package from NuGet.
+
+    Package versions take a single shape, produced by Versions.props from the pipeline build number.
+    Preview versions carry the full build number after the prerelease suffix, such as
+    1.2.3-preview1.26238.3. Stable versions are left exactly as declared in Versions.props, such as
+    1.2.3, because released packages are not stamped with a build number.
+
+    File versions are always four-part and always carry a build number in the fourth component, even
+    when the package version does not. Versions.props derives that component from the date segment of
+    BuildNumber, so a package version of 1.2.3-preview1.26238.3 has file version 1.2.3.26238, and a
+    stable package version of 1.2.3 still has file version 1.2.3.26238. That segment is date-coded,
+    so repeated runs on the same day share a file version even though their package versions differ.
+
+    An unbuilt SqlServer package is never stamped with a build number because its effective version
+    must continue to identify the package that already exists on NuGet.
+
+    The script emits these output variables for downstream stages:
+      - SqlClientPackageVersion
+      - SqlClientFileVersion
+      - SqlServerPackageVersion
+      - SqlServerFileVersion
+      - SqlClientApiScanVersion
+      - SqlServerApiScanVersion
+
+.PARAMETER ProjectPath
+    Absolute or relative path to the repository build.proj file.
+
+.PARAMETER BuildNumber
+    Pipeline build number in the form <date>.<run>, such as 26238.3. Versions.props appends it to
+    prerelease package versions and derives the file-version build number from its date segment.
+
+.PARAMETER BuildSqlServer
+    Whether this run builds Microsoft.SqlServer.Server. When false, the effective SqlServer package
+    version is its last published version and its file version is not consumed downstream.
+
+.PARAMETER DotnetPath
+    dotnet executable to invoke. Defaults to the dotnet command resolved from PATH. This parameter
+    primarily supports isolated testing and specialized agent configurations.
+
+.EXAMPLE
+    ./compute-versions.ps1 `
+        -ProjectPath ./build.proj `
+        -BuildNumber 26238.3 `
+        -BuildSqlServer $true
+
+    Computes versions for a run that builds SqlServer. Prerelease package versions become
+    7.1.0-preview3.26238.3 and file versions become 7.1.0.26238.
+
+.EXAMPLE
+    ./compute-versions.ps1 `
+        -ProjectPath ./build.proj `
+        -BuildNumber 26238.3 `
+        -BuildSqlServer $false
+
+    Stamps the SqlClient family versions while retaining SqlServerPublishedVersion for dependency
+    restore because SqlServer is not built in this run.

+<#
+.SYNOPSIS
+    Publishes symbols to the Microsoft symbol publishing service (SymWeb/MSDL).
+
+.DESCRIPTION
+    This script is Step 2 of the two-step symbols publishing process. It requests
+    the Symbols Publishing Pipeline to publish previously uploaded PDB files to
+    internal (SymWeb) and/or public (MSDL) Microsoft symbol servers.
+
+    The two-step process:
+      Step 1 (PublishSymbols@2 task in publish-symbols-step.yml):
+        Uploads PDB files to the Azure DevOps symbol store under a unique
+        artifact name (SymbolsArtifactName). This stores the symbols but does
+        NOT make them available on SymWeb or MSDL.
+
+      Step 2 (this script):
+        Calls the Symbols Publishing Pipeline REST API to request that the
+        uploaded symbols be published to the symbol servers.
+
+    Step 2 depends on Step 1: the -ArtifactName parameter MUST match the
+    SymbolsArtifactName used by the PublishSymbols@2 upload task so that
+    both steps reference the same uploaded artifact.
+
+    This script performs four sub-steps:
+      1. Acquires a bearer token from Azure CLI for the symbol publishing service.
+      2. Registers a unique request name with the publishing service.
+      3. Submits the request to publish symbols to the specified servers.
+      4. Queries the publishing status for confirmation.
+
+    For more details on the Symbols Publishing Pipeline, see:
+    https://www.osgwiki.com/wiki/Symbols_Publishing_Pipeline_to_SymWeb_and_MSDL
+
+.PARAMETER PublishServer
+    The hostname prefix of the symbol publishing service. This value is prepended to
+    '.trafficmanager.net' to construct the service base URL.
+
+.PARAMETER PublishTokenUri
+    The resource URI used to acquire a bearer token from Azure CLI
+    (via 'az account get-access-token --resource <uri>').
+
+.PARAMETER PublishProjectName
+    The project name registered with the symbol publishing service (decided during onboarding).
+
+.PARAMETER ArtifactName
+    The name of the publishing request. This must match the SymbolsArtifactName used by
+    the PublishSymbols@2 upload task so that upload and publish reference the same artifact.
+
+.PARAMETER PublishToInternal
+    Whether to publish symbols to the internal symbol server. Defaults to $true.
+
+.PARAMETER PublishToPublic
+    Whether to publish symbols to the public symbol server. Defaults to $true.
+
+.EXAMPLE
+    .\publish-symbols.ps1 `
+        -PublishServer "mysymbolserver" `
+        -PublishTokenUri "https://login.microsoftonline.com/..." `
+        -PublishProjectName "Microsoft.Data.SqlClient.SNI" `
+        -ArtifactName "mds_symbols_MyProject_dotnet-sqlclient_main_7.0.0_abc123_1"
+
+    Publishes symbols to both internal and public servers using the specified parameters.
+
+.EXAMPLE
+    .\publish-symbols.ps1 `
+        -PublishServer "mysymbolserver" `
+        -PublishTokenUri "https://login.microsoftonline.com/..." `
+        -PublishProjectName "Microsoft.Data.SqlClient.SNI" `
+        -ArtifactName "mds_symbols_MyProject_dotnet-sqlclient_main_7.0.0_abc123_2" `
+        -PublishToPublic $false
+
+    Publishes symbols to the internal server only (retry attempt 2).

+# OneBranch PowerShell Tests
+
+Pester tests for PowerShell scripts used by OneBranch pipeline steps.
+
+## Prerequisites
+
+- PowerShell 5.1+ or PowerShell 7+
+- [Pester v5](https://pester.dev/) (`Install-Module Pester -MinimumVersion 5.0 -Scope CurrentUser`)
+
+## Running the Tests
+
+From this directory:
+
+```powershell
+Invoke-Pester ./publish-symbols.Tests.ps1
+```
+
+Or from the repository root:
+
+```powershell
+Invoke-Pester ./eng/pipelines/onebranch/scripts/tests/
+```
+
+For detailed output:

+## Test Coverage
+
+| Area                  | What's tested                                                    |
+| --------------------- | ---------------------------------------------------------------- |
+| Version computation   | Canonical output parsing, effective package selection, target version composition, and failures |
+| Localization validation | Missing, obsolete, or empty strings, English-value matches, and culture-specific allowlisting |
+| Parameter validation  | Empty strings rejected for all mandatory parameters              |
+| URL construction      | Base URL, register URL, request URL built from parameters        |
+| Request bodies        | Registration body, default publish flags, flag overrides         |
+| Error handling        | Token failure, registration failure, publish failure, status failure — all verify expanded URI in error message |
+| Status validation     | Detects Failed/Cancelled results, respects PublishToInternal/PublishToPublic flags, passes on Succeeded/Pending |
+| Package validation    | Wildcard vs per-id version expectations, SqlServer omitted when unbuilt, gate tokens, report written before gating, exit-code handling |
+| Package signatures    | Every package and symbol package verified, all failures reported before throwing |
+| Assembly signatures   | Package expansion, native binaries under `runtimes/` included, stale expansions replaced, all unsigned assemblies reported |
+
+## Notes
+
+- All external calls (`az`, `Invoke-RestMethod`) are mocked — no network access or Azure credentials are required.
+- Script-level version tests mock `dotnet`; package-composition tests invoke the real MSBuild
+  `GetVersionsSqlClient` and `GetVersionsSqlServer` targets.
+- `Get-AuthenticodeSignature` is Windows-only, so the assembly-signature tests declare a stub when
+  it is absent. Only the signature lookup is substituted; package expansion and reporting run for
+  real against packages built in the test's temporary directory.
+- Tests validate scripts in the parent directory relative to this directory.

+<#
+.SYNOPSIS
+    Runs the PackageValidator tool over the NuGet packages produced by a OneBranch build.
+
+.DESCRIPTION
+    Invokes tools/PackageValidator once for a whole directory of packages rather than once per
+    package, because its most valuable checks are cross-package: every package in the SqlClient
+    family must carry the same version, and their inter-package dependency ranges must agree.
+    Validating one package at a time would silently skip all of those findings.
+
+    The validator runs twice over the same inputs. The first run writes a machine-readable report
+    and never gates, so the report exists even when validation fails. The second run renders the
+    human-readable report and applies the gate, so a failing build shows its findings in its own
+    log rather than only in an artifact.
+
+    Expected versions are supplied by the caller rather than derived here. The compute-versions
+    stage already computes every version the build stamps, and re-deriving them would reintroduce
+    the drift this validation exists to catch.
+
+    Microsoft.SqlServer.Server is versioned separately from the SqlClient family, so its expected
+    versions are applied as a per-id override of the family wildcard. When it is not built in a
+    run, its package is absent from the drop and its expectations must be omitted entirely: the
+    validator rejects an expectation whose value is empty.
+
+.PARAMETER ValidatorPath
+    Path to the built PackageValidator.dll. Invoked through the managed assembly rather than the
+    native apphost so the same command works regardless of agent OS.
+
+.PARAMETER PackagesPath
+    Directory scanned recursively for .nupkg files. Sibling .snupkg files must sit beside their
+    .nupkg for symbol matching to resolve, which is how the build jobs publish them.
+
+.PARAMETER ReportPath
+    Path of the JSON report to write. Parent directories are created as needed.
+
+.PARAMETER SqlClientPackageVersion
+    Package version expected of every package in the SqlClient family, applied as a wildcard.
+    Pointing every package at one value is what proves they agree, and also catches the case where
+    all of them are consistently wrong.
+
+.PARAMETER SqlClientFileVersion
+    Assembly file version expected of every assembly in the SqlClient family.
+
+.PARAMETER SqlServerPackageVersion
+    Package version expected of Microsoft.SqlServer.Server. Omit when SqlServer is not built.
+
+.PARAMETER SqlServerFileVersion
+    Assembly file version expected of Microsoft.SqlServer.Server. Omit when SqlServer is not built.
+
+.PARAMETER FailOn
+    Finding severities and/or categories that fail the build. Run the validator with --help to see
+    the available categories. Note that missing-symbols is a warning and package-unsigned is info,
+    so neither is covered by the error severity and both must be named explicitly.
+
+    Accepts either an array or a single comma-separated string, because an Azure Pipelines task
+    argument line collapses to one token and PowerShell's -File mode does not split it.
+
+.PARAMETER DotnetPath
+    dotnet executable to invoke. Defaults to the dotnet command resolved from PATH. This parameter
+    primarily supports isolated testing.
+
+.EXAMPLE
+    ./validate-packages.ps1 `
+        -ValidatorPath ./PackageValidator.dll `
+        -PackagesPath ./packages `
+        -ReportPath ./out/report.json `
+        -SqlClientPackageVersion 7.1.0-preview3.26238.3 `
+        -SqlClientFileVersion 7.1.0.26238 `
+        -FailOn error,missing-symbols
+
+    Validates a family-only drop, failing on any error and on missing symbols.

+<#
+.SYNOPSIS
+    Verifies that every assembly shipped inside an official build's NuGet packages is Authenticode
+    signed.
+
+.DESCRIPTION
+    Expands each .nupkg beneath a directory and checks the Authenticode signature of every assembly
+    it contains, including native binaries under runtimes/.
+
+    Packages are expanded rather than installed through NuGet so that every produced package is
+    covered without resolving dependencies, and so that the check does not depend on any single
+    package id.
+
+    This complements PackageValidator, which reports strong-name state from assembly metadata
+    cross-platform. Authenticode verification requires the Windows trust store, so this script runs
+    only on Windows agents and only for official builds; non-official builds deliberately produce
+    unsigned assemblies.
+
+    Every assembly is checked before failing, so a single run reports all unsigned assemblies
+    rather than stopping at the first.
+
+.PARAMETER PackagesPath
+    Directory scanned recursively for .nupkg files to expand.
+
+.PARAMETER ExtractPath
+    Directory the packages are expanded into. Each package is expanded into its own subdirectory so
+    that identically-named assemblies from different packages cannot collide. Existing content for
+    a package is replaced.
+
+.EXAMPLE
+    ./verify-assembly-signatures.ps1 -PackagesPath ./packages -ExtractPath ./extract
+
+    Expands every package beneath ./packages and verifies the signature of each assembly.

+<#
+.SYNOPSIS
+    Verifies the NuGet signatures of every package produced by an official OneBranch build.
+
+.DESCRIPTION
+    Runs `dotnet nuget verify --all` over every .nupkg and .snupkg found beneath a directory,
+    confirming that each carries a valid, trusted signature.
+
+    This complements PackageValidator, which reports signature *presence* from package metadata
+    cross-platform. Establishing that a signature is trusted requires the platform trust store,
+    which is why this runs separately and only on official builds. Non-official builds deliberately
+    produce unsigned packages, so verifying them would always fail.
+
+    Every package is verified before failing, so a single run reports all unsigned packages rather
+    than stopping at the first.
+
+.PARAMETER PackagesPath
+    Directory scanned recursively for .nupkg and .snupkg files.
+
+.PARAMETER DotnetPath
+    dotnet executable to invoke. Defaults to the dotnet command resolved from PATH. This parameter
+    primarily supports isolated testing.
+
+.EXAMPLE
+    ./verify-package-signatures.ps1 -PackagesPath ./packages
+
+    Verifies every package and symbol package beneath ./packages.

+      # See https://aka.ms/gdn-azdo-break.
+      #
+      # Guardian normalises every finding to Error, Warning or Note.  The threshold is cumulative,
+      # so a lower name is STRICTER, not looser:
+      #
+      #   Error    break on Error                     <-- Guardian's default

+      # inheriting the default requires omitting the key.  Consequently, spelling out

+        #   break-altering logic in the past, so both `tsa.enabled` and each tool's `break` are

+      #
+      # The SDL analyzer tasks never fail on findings; they only fail if the tool itself crashes or
+      # is misconfigured.  The build break comes from the Post Analysis (Guardian Break) task, which
+      # reads the tool logs and fails when a finding meets or exceeds a minimum severity threshold.
+      # See https://aka.ms/gdn-azdo-break.
+      #
+      # Guardian normalises every finding to Error, Warning or Note.  The threshold is cumulative,
+      # so a lower name is STRICTER, not looser:
+      #
+      #   Error    break on Error                     <-- Guardian's default
+      #   Warning  break on Error + Warning
+      #   Note     break on Error + Warning + Note
+      #
+      # Two knobs control it, in increasing order of precedence:
+      #
+      #   globalSdl.severity           threshold for every tool (maps to GdnBreakPolicyMinSev)
+      #   globalSdl.<tool>.severity    per-tool override of the global threshold
+      #   ob_sdl_<tool>_severity       per-job variable; overrides both of the above
+      #
+      # We omit `severity` everywhere and keep the Error-only default.  OneBranch accepts ONLY
+      # Error, Warning or Note at this layer -- there is no explicit "Default" value to write, so
+      # inheriting the default requires omitting the key.  Consequently, spelling out
+      # `severity: Error` on a tool is NOT equivalent to omitting it: it pins that tool to Error

+# Compute Versions Stage
+# ======================
+# Computes package versions up-front in a single fast job.  Downstream stages
+# consume these via stage/job output variables, e.g.:
+#
+#   stageDependencies.compute_versions.compute_versions_job.outputs['versions.SqlClientPackageVersion']
+#
+# Design:
+#   - The SqlClient family (Logging, Abstractions, SqlClient, Azure, AKV Provider) shares a single
+#     version and always uses its "next" version (from Versions.props + BuildNumber).
+#   - Microsoft.SqlServer.Server is versioned separately: it uses its "next" version when it is
+#     being built this run, or its "published" (last shipped to NuGet) version when it is not built
+#     (so the SqlClient family depends on the most recently published SqlServer package).
+#   - Runs use their "next" version from Versions.props. The pipeline build number is appended to
+#     prerelease package versions (7.1.0-preview3.26238.3) and its date segment becomes the
+#     file-version build number (7.1.0.26238), matching the shape shipped by earlier previews.
+#   - Versions are extracted via build.proj GetVersions* targets by parsing stdout.
+#
+# This stage MUST run before all build stages so they can consume computed versions.
+
+parameters:
+  # Whether Microsoft.SqlServer.Server is being built this run.  This drives the SqlServer version
+  # selection (next when built, published when not); the SqlClient family always uses its next
+  # version.  When SqlServer is not built, the SqlClient family depends on the published SqlServer

+# Symbols Publishing Pipeline
+# ===========================
+# Canonical docs: https://www.osgwiki.com/wiki/Symbols_Publishing_Pipeline_to_SymWeb_and_MSDL
+#
+# Publishing symbols to SymWeb (internal) and MSDL (public) is a two-step process:
+#
+#   Step 1 - Upload:  The PublishSymbols@2 task uploads PDB files to the Azure DevOps
+#            symbol store under an artifact name (SymbolsArtifactName). This stores the
+#            symbols but does NOT make them available on SymWeb or MSDL.
+#
+#   Step 2 - Publish: The publish-symbols.ps1 script calls the Symbols Publishing Pipeline
+#            REST API to request that the previously uploaded symbols be published to the
+#            internal (SymWeb) and/or public (MSDL) symbol servers.
+#
+# IMPORTANT: Step 2 depends on Step 1. The ArtifactName parameter passed to the publish
+# script MUST match the SymbolsArtifactName used by PublishSymbols@2 so that both steps
+# reference the same uploaded artifact.
+
 parameters:

+# This template runs Roslyn Analyzers (SDL) against a build.proj target using the RoslynAnalyzers@3
+# task from the Secure Development Team's SDL extension, in "Copy Logs Only" mode:
+#
+# https://eng.ms/docs/cloud-ai-platform/devdiv/one-engineering-system-1es/1es-mohanb/security-integration/guardian-wiki/sdl-azdo-extension/roslyn-analyzers-build-task
+#
+# PROVENANCE: Every statement in this file about how the RoslynAnalyzers task behaves is current as
+#   of task version v3 (RoslynAnalyzers@3, 3.289.0) and was verified against concrete evidence -- the
+#   actual pipeline run logs, the task definition (task.json / inputMap.json), the gdn-task-lib task
+#   source, and the Guardian RoslynAnalyzers CLI binaries (Microsoft.Guardian.RoslynAnalyzers*.dll).
+#   Re-verify these claims if the task's major version changes.
+#
+# HOW IT WORKS (integrated analyzers + Copy Logs Only):
+#   .NET [Roslyn] security analyzers are compiler-integrated: they only run as part of the actual
+#   csc/vbc compilation. build.proj is an orchestrator -- each package's real compile happens in a
+#   separate "dotnet build <project>.csproj" that build.proj launches with an <Exec> task. That is
+#   the crux: anything the RoslynAnalyzers task appends to an *outer* "dotnet build build.proj"
+#   command (its auto/manual "re-run the build" modes) is an MSBuild global property, and global
+#   properties do NOT cross an <Exec> into a child "dotnet build" process. So an injected analyzer
+#   would only ever see build.proj (which compiles nothing) and never the real projects, producing
+#   zero results. That is exactly why earlier auto/manual-mode attempts collected 0 SARIF logs.
+#
+#   Instead we use the task's documented "Copy Logs Only" alternative -- integrate the analyzers into
+#   the build itself, then have the task only collect the results:
+#     1. This step runs its own isolated "dotnet build build.proj -t:Build<Package>" with
+#        EnableAnalyzers=true. build.proj forwards that flag into every leaf "dotnet build" it execs
+#        (via EnableAnalyzersArgument), and src/Directory.Build.props -- which every product project
+#        imports -- reacts by enabling the full analyzer set and setting ErrorLog to a per-project
+#        "*.csproj.<guid>.sarif" log. src/Directory.Build.targets verifies that each leaf compile
+#        produced its configured log. Because the analyzers and verification are enabled on the leaf
+#        projects themselves, they run inside the real compiles regardless of the <Exec> boundary.
+#     2. The RoslynAnalyzers@3 task then runs in Copy Logs Only mode (copyLogsOnly: true) and simply
+#        collects and sanitizes those *.csproj.*.sarif and *.vbproj.*.sarif logs from
+#        logRootDirectory for SDL/Guardian compliance. It performs no build and no compiler re-run,
+#        so none of the msBuildVersion /
+#        msBuildArchitecture / Visual-Studio-setup concerns apply -- the task never needs MSBuild,
+#        so it is inherently agnostic to the container's VS/MSBuild version (e.g. MSBuild 18 on the
+#        ltsc2025/vse2026 image).
+#
+#   EnableAnalyzers and IsolatedBuildPath are independent build.proj properties. We set both here:
+#   EnableAnalyzers turns analysis on; IsolatedBuildPath keeps this analysis build from disturbing
+#   real build output (see ISOLATION).
+#
+# WHAT THE TASK ITSELF INJECTS (v3), AND HOW THIS TEMPLATE COVERS IT:
+#   In its build-driving modes the task appends five MSBuild properties to the compile command and
+#   injects the analyzers via user-profile ImportBefore/ImportAfter files. This template enables the
+#   analyzers on the leaf projects instead, reproducing the effects that matter. Item by item:
+#

+#   WHY THE TASK'S OWN INJECTION YIELDS 0 SARIF THROUGH build.proj: the ImportAfter *.targets live in
+#   the user profile, so they ARE imported by build.proj's inner "dotnet build <csproj>" execs -- but
+#   they self-gate on $(GdnRoslynAnalyzersRunId), and that property (like CodeAnalysisRuleSet and
+#   Features) is passed only on the OUTER "dotnet build build.proj" command and does not cross the
+#   <Exec> into the child compiles. So the injected targets no-op in the real compiles. Enabling the
+#   analyzers on the leaf projects (EnableAnalyzers) removes that gate entirely.
+#
+# NOTE ON THE INTERNAL IA* RULES:
+#   The SDL-recommended ruleset also contains internal IA* ("Internal Analyzers") rules that ship in
+#   the Microsoft.Internal.Analyzers package. That package is Microsoft-internal and confidential: it
+#   is NOT on nuget.org, and it MUST NOT be added to this repo's governed feed
+#   (sqlclientdrivers.pkgs.visualstudio.com/public/...), which is PUBLIC-scoped -- doing so would
+#   leak internal tooling and breach its internal-use license. So the leaf-project analysis above
+#   (AnalysisLevel=latest-recommended) covers the CA* rules but NOT the IA* rules.
+#
+#   The IA* rules can only be run from the PRIVATE ADO.Net project pipelines, where a Microsoft-
+#   internal NuGet feed is reachable. NuGet.analysis.config adds that feed using an environment-
+#   variable placeholder and maps Microsoft.Internal.* exclusively to it. Only these analysis builds
+#   select that config, allowing Microsoft.Internal.Analyzers to be restored and used without
+#   changing the normal NuGet.config.
+#
+# ISOLATION:
+#   This template is self-contained and safe to run at any point in a job -- before or after a real
+#   build -- because the analysis build writes its binaries to a separate location and never touches
+#   the real build output, using the IsolatedBuildPath build.proj property.

+# SqlClient Performance Test Pipeline
+
+This directory contains the Azure DevOps pipeline and supporting scripts that run the
+Microsoft.Data.SqlClient [BenchmarkDotNet](https://benchmarkdotnet.org/) performance tests on a
+dedicated performance test lab (Azure Dedicated Hosts), compare the branch under test against a
+released NuGet baseline, and optionally ingest the results into an Azure Data Explorer (Kusto)
+database.
+
+## Contents
+
+| Path | Purpose |
+| ---- | ------- |
+| `sqlclient-perf-pipeline.yml` | The main (manual/nightly) pipeline. Extends `v1/Perf.Test.Job.yml@PerfTemplates`. Baseline = released NuGet package; ingests into Kusto. |
+| `sqlclient-perf-pr-pipeline.yml` | PR pipeline. Same template, same scripts, same options; baseline = **`release/7.1` branch source**; **no Kusto ingestion**. |
+| `sqlclient-perf-experiment.yml` | Experiment pipeline. Same template, same scripts; both passes build the **same source** and differ only in one runner-config switch; **no Kusto ingestion**. |
+| `scripts/run-perf-tests.sh` | Linux on-VM entry point: install SDK, create DB, run benchmarks (interleaved or sequential), compare. Baseline is a released package (`--baseline-version`), another git ref's source (`--baseline-source-ref`), or the same source with one runner-config switch flipped off (`--switch-under-test`). |
+| `scripts/run-perf-tests.ps1` | Windows equivalent (ProcessorAffinity instead of `taskset`). |
+| `scripts/interleave_perf.py` | Interleaved + best-of-N orchestrator: runs each unit baseline↔candidate back-to-back and confirms regressions across N passes. |
+| `scripts/compare_perf.py` | Compares baseline vs current BenchmarkDotNet JSON → delta (md + json). Reused by the orchestrator. |
+| `scripts/perf_to_kusto.py` | Translates BenchmarkDotNet "full" JSON → Kusto `PerfRun` + `PerfBenchmarkResult` NDJSON. |
+| `scripts/ingest_kusto.py` | Queued Kusto ingestion (az CLI auth, runs on the agent). |
+
+## Architecture
+
+```
+Queue pipeline (ADO)
+      │
+      ▼
+extends: v1/Perf.Test.Job.yml@PerfTemplates
+      │  (provisions a dedicated-host VM, SCPs the repo, runs the script over SSH,
+      │   SCPs <testResultsSubDir> back, publishes it, tears the VM down)
+      ▼
+ON THE VM  ── run-perf-tests.{sh,ps1}
+      1. Install the .NET SDK pinned by global.json (+ runtimes).
+      2. Create the perf database on the VM's SQL Server.
+      3. Inject the VM SQL connection string into runnerconfig.
+      4. Baseline pass  → MDS <baselineVersion> from NuGet.org (Package mode)   → results/baseline/
+         (PR pipeline: MDS built from the <baselineSourceRef> source tree)
+      5. Current  pass  → MDS built from source (ProjectReference)              → results/current/
+         (both pinned to PERF_CLIENT_CPUS; interleaved per-unit by default, or two full
+          sequential passes when benchmarkRunMode=sequential)
+      6. interleave_perf.py / compare_perf.py → results/comparison/ + results/summary.md
+      ▼
+ON THE AGENT  ── pipeline post-test steps
+      • Show the BenchmarkDotNet markdown reports in the log.
+      • perf_to_kusto.py → NDJSON for both passes (published as 'perf-kusto-payloads').
+      • (optional) AzureCLI@2 + ingest_kusto.py → Kusto database.
+      (both Kusto steps are omitted entirely in the PR pipeline)
+```
+
+The extends template only exposes **post-test** steps to consumers (no pre-build hook), so **both
+benchmark passes run inside the on-VM script**. Translation and ingestion run on the **agent**
+because that is where the pipeline's AAD identity / service connection and the native pipeline
+context variables are available (the VM is behind NAT and lacks the pipeline identity).
+
+## Parameters
+
+| Parameter | Default | Description |
+| --------- | ------- | ----------- |
+| `platform` | `linux` | `linux` or `windows` VM + client. |
+| `dotnetFramework` | `net9.0` | TFM the benchmarks run against (`net8.0`/`net9.0`/`net10.0`). |
+| `testTimeoutMinutes` | `180` | Template timeout waiting for the VM run. |
+| `baselineVersion` | `7.0.2` | **Baseline Version** — released MDS the branch is compared against. Empty = current-only (no baseline pass / comparison). |
+| `regressionThreshold` | `10` | Percent slowdown (current vs baseline mean) flagged as a regression. |
+| `failOnRegression` | `false` | When `true`, a candidate-slower regression **fails** the run (gate). In interleaved mode only **confirmed** regressions (best-of-N majority) fail. Default off. |
+| `benchmarkRunMode` | `interleaved` | `interleaved` (per-unit baseline↔candidate + best-of-N confirmation) or `sequential` (legacy two full passes). |
+| `confirmationRuns` | `3` | Best-of-N: interleaved passes for a flagged unit before a regression is confirmed. `1` disables confirmation. Interleaved mode only. |
+| `useManagedSniOnWindows` | `false` | SqlClient `UseManagedSniOnWindows` flag. Applied to the runner config for **both** passes on the VM and recorded in `PerfRun.Config`. Default matches the checked-in `runnerconfig.jsonc`. |
+| `useOptimizedAsyncBehaviour` | `true` | SqlClient `UseOptimizedAsyncBehaviour` flag. Applied to both passes and recorded in `PerfRun.Config`. Default matches `runnerconfig.jsonc`. |
+| `useConnectionPoolV2` | `false` | SqlClient `UseConnectionPoolV2` flag. Applied to both passes and recorded in `PerfRun.Config`. Default matches `runnerconfig.jsonc`. |
+| `enableKustoIngestion` | `true` | **Ingest results into Kusto** — when `false`, the run still benchmarks + compares but skips ingesting into the perf database. When `true`, ingestion additionally requires the `ADX Cluster Variables` group to be populated. |
+
+The following values are **fixed constants** in the pipeline (not parameters or variables), since they
+are invariant for this pipeline: `buildConfiguration = Release`, `sourcesSubDir = dotnet-sqlclient`
+(the multi-repo checkout folder for `self`, which must match the ADO repository name), and
+`driverName = Microsoft.Data.SqlClient` (recorded on every row as `DriverName` / `DerivedRunId`).
+
+### Kusto (Azure Data Explorer) ingestion variables
+
+The ADX ingestion coordinates are **not** pipeline parameters — they come from a pipeline library
+variable group named **`ADX Cluster Variables`** so no infrastructure identifiers are hard-coded in
+the pipeline. The group must define:
+
+| Variable | Description |
+| -------- | ----------- |
+| `KustoClusterUri` | ADX cluster URI, e.g. `https://<cluster>.<region>.kusto.windows.net`. Empty ⇒ ingestion skipped. |
+| `KustoDatabase` | Target Kusto database. Empty ⇒ ingestion skipped. |
+| `KustoServiceConnection` | Azure DevOps ARM service connection whose SP has ingest rights. Empty ⇒ ingestion skipped. |
+
+Ingestion is gated at runtime: it only runs when `KustoClusterUri`, `KustoDatabase` and
+`KustoServiceConnection` are all non-empty, so the pipeline still runs + compares before the
+cluster/service connection exist.
+
+### Managing the baseline version
+
+`baselineVersion` is **manually managed**. After each stable release is published to NuGet.org,
+bump the `default` in `sqlclient-perf-pipeline.yml` (e.g. `7.0.2` → the next stable). It can also be
+overridden at queue time without editing the pipeline.
+
+## PR pipeline (`sqlclient-perf-pr-pipeline.yml`)
+
+`sqlclient-perf-pr-pipeline.yml` answers the question a PR author actually has — *does my branch
+regress the branch I am merging into?* — by running the **same** benchmarks, on the **same** extends
+template, through the **same** on-VM scripts, with the **same** configuration options as the main
+pipeline. It differs in exactly two ways:
+
+| | `sqlclient-perf-pipeline.yml` | `sqlclient-perf-pr-pipeline.yml` |
+| --- | --- | --- |
+| Candidate | branch the run is queued on | branch the run is queued on (unchanged) |
+| Baseline | released NuGet package (`baselineVersion`, default `7.0.2`) | **source of another git ref** (`baselineSourceRef`, default `release/7.1`) |
+| Kusto | translates + (optionally) ingests | **never** — no ADX variable group, no translate/ingest steps |
+
+Both pipelines are **manual / queue-time only** (`pr: none`, `trigger: none`): a run occupies a
+dedicated host for hours, so a PR opts into it explicitly.
+
+PR-only parameters (everything else is identical to the table above):
+
+| Parameter | Default | Description |
+| --------- | ------- | ----------- |
+| `baselineSourceRef` | `release/7.1` | Git ref of this repo whose **source** is the baseline. Empty = current-only (no baseline pass / comparison). |
+| `baselineRepoUrl` | `https://github.com/dotnet/SqlClient.git` | Fallback remote used to obtain the baseline ref when the VM copy of the checkout cannot fetch it from its own `origin`. |
+| `testTimeoutMinutes` | `210` | Higher than the main pipeline's `180` because **both** sides are built from source. |
+
+### Source baseline (`--baseline-source-ref` / `-BaselineSourceRef`)
+
+The run scripts accept the source baseline as an alternative to `--baseline-version` (the two are
+mutually exclusive and the script fails fast if both are supplied). On the VM the script:
+
+1. Materialises the baseline ref next to the checkout, in `../sqlclient-perf-baseline-src` — outside
+   the checkout so it can never be picked up by the candidate build or the results copy. It first
+   tries the copied checkout's own `origin` (`git fetch --depth 1` into a private
+   `refs/remotes/perfbaseline/*` namespace, then `git worktree add --detach`), and falls back to a
+   shallow `git clone` of `baselineRepoUrl` when the tree arrived without `.git` or `origin` needs
+   credentials. On ADO the origin fetch is *expected* to fail — the checkout is copied to the VM
+   without credentials — so the clone fallback is the normal path there. Every network git call runs
+   non-interactively (`GIT_TERMINAL_PROMPT=0`, no credential helper, stdin closed) under a
+   `GIT_NET_TIMEOUT_SECS` timeout (default 300s), and its output is kept in
+   `<results>/diagnostics/git-*.log`, so a missing credential fails in under a second instead of
+   blocking the job on a prompt.
+2. Builds **that ref's own `PerformanceTests` project** as the `baseline` variant, so the driver
+   under measurement is the baseline ref's source via `ProjectReference` — mirroring how the
+   `current` variant is built from this branch. No NuGet baseline config is involved.
+3. Labels the comparison `"<ref>@<short-sha>"` (e.g. `main@a1b2c3d`) so a run states exactly which
+   baseline commit it was measured against, and writes that label to
+   `<results>/baseline-label.txt`. The PR pipeline reads that file after the results are copied
+   back and tags the build `Baseline <ref>@<short-sha>`, so the exact baseline commit is visible in
+   the ADO build list. (The pipeline cannot produce this tag on its own — at compile time it only
+   knows the ref name, which would tag every run identically.)
+
+Because each side builds its own harness, a benchmark added by the PR simply shows up as `new` in
+the comparison (and one removed by the PR as `removed`) instead of failing the run. Both passes
+share the single generated runner config (`RUNNER_CONFIG` / `DATATYPES_CONFIG` env vars), so
+connection string and behaviour flags are identical on both sides.
+
+## Experiment pipeline (`sqlclient-perf-experiment.yml`)
+
+The three perf pipelines are the same benchmarks, template and scripts pointed at three different
+questions. Two of them vary the **source** under measurement; the third varies the **config**:
+
+| Question | Pipeline | Baseline | Current |
+| --- | --- | --- | --- |
+| Has this branch regressed against a released package? | `sqlclient-perf-pipeline.yml` | released NuGet package | queued branch |
+| Does my PR regress the branch it merges into? | `sqlclient-perf-pr-pipeline.yml` | `release/7.1` source | queued branch |
+| What does this switch cost or buy? | `sqlclient-perf-experiment.yml` | queued branch, switch **off** | queued branch, switch **on** |
+
+`sqlclient-perf-experiment.yml` picks one runner-config switch via the `switchUnderTest`
+queue-time parameter (`UseConnectionPoolV2`, `UseOptimizedAsyncBehaviour` or
+`UseManagedSniOnWindows`) and runs the baseline pass with it `false` and the current pass with it
+`true`. Both passes measure the **same commit** — the branch the run is queued on — so queue it on a
+PR branch to ask "what does this switch do to my change?", or on `main` to ask "what does it do to
+`main`?".
+
+Two passes are required because these are `AppContext` switches latched process-wide (for example
+`UseConnectionPoolV2` is read and cached the first time a connection pool is created), so they cannot
+be toggled between benchmarks within a single process. The pipeline wires that into the existing
+comparison machinery — interleaved best-of-N or sequential, via `benchmarkRunMode` — instead of two
+ad hoc manual runs.
+
+Switch-pipeline parameters that differ from the tables above:
+
+| Parameter | Default | Description |
+| --------- | ------- | ----------- |
+| `switchUnderTest` | `UseConnectionPoolV2` | The single switch to A/B. Baseline forces it `false`, current forces it `true`. |
+| `failIfSwitchSlower` | `false` | Maps onto the scripts' `--fail-on-regression` gate, but means something different here: "switch on is slower" is usually the *result* you queued the run to measure, not a defect. Enable it only when asserting the switch must not be a slowdown (e.g. before flipping its default). |
+| `testTimeoutMinutes` | `180` | Same as the main pipeline, not the PR pipeline's `210`: both sides are the same source, so only **one** driver build is needed. |
+
+The pipeline deliberately does **not** expose `baselineVersion` / `baselineSourceRef` (the run
+scripts reject combining those with `--switch-under-test`, since a simultaneous source change would
+make the delta unattributable), nor the `useManagedSniOnWindows` / `useOptimizedAsyncBehaviour` /
+`useConnectionPoolV2` flags. Every switch except the one under test stays at its checked-in
+`runnerconfig.jsonc` value, so the measured difference is attributable to exactly one variable.
+
+### Why these runs are never ingested into Kusto
+
+This mode has its own pipeline file, rather than being a flag on the other two, specifically so that
+"never ingested" is structural rather than a conditional someone can flip. Ingesting a switch
+experiment would corrupt the perf database three ways:
+
+* **`DerivedRunId` collision.** The ID is `driver|commit|pipelineRunId`. The other two pipelines keep
+  their two rows distinct because the baseline row carries a *different* commit (`v7.0.2`, or the
+  baseline ref's sha). Here both passes are the same commit in the same pipeline run, so both rows
+  would derive the same ID.
+* **`PerfRun.Config` is stamped once per run.** `translate_results_to_kusto.sh` builds one
+  `--config-override` set from the queue-time `CFG_*` values and reuses it for both the baseline and
+  current rows. That is correct when the config genuinely is shared, but it means the two rows could
+  not record the differing switch values that are the entire point of the experiment.
+* **Trend pollution.** No field marks a row as an experiment — `RunType` is already
+  `Sequential`/`Interweaved` — so the switch-on pass would be indistinguishable from an ordinary
+  measurement of the branch and would distort the very trends the other two pipelines exist to
+  protect.
+
+The comparison report and the raw BenchmarkDotNet artifacts are published as usual, and the build is
+tagged `Switch <name>` so experiments are identifiable in the ADO build list.
+
+### Designing benchmarks for switch experiments
+
+A switch experiment flips behaviour on purpose, so a benchmark that measures that behaviour will
+report a regression even when the change is working. `UseConnectionPoolV2` is the motivating example:
+`ChannelDbConnectionPool` opens physical connections concurrently, where `WaitHandleDbConnectionPool`
+serialises growth behind a `Semaphore(1, 1)`. `ConnectionPoolStressRunner` used to call
+`ClearAllPools()` in `[IterationCleanup]`, so every iteration was a cold-start burst in which the
+extra parallel opens had nothing to amortise against, and the runner reported the trade-off as a loss
+because that was the only thing it could measure.
+
+That is a benchmark defect rather than something to explain away, so the runner now pre-warms the
+pool to full capacity in `[GlobalSetup]` and no longer clears it between iterations. Establishing a
+connection costs milliseconds while a pooled checkout costs microseconds, so any creation left in the
+measured body swamps the pool cost the runner exists to measure. Keep that separation in mind when
+adding a pool benchmark: warm the pool first unless connection establishment is precisely the thing
+under test.
+
+The pipeline has no way to mark a result as acceptable, and deliberately so: a mute is only as good
+as the reasoning behind it, and that reasoning belongs in the pull request where a reviewer can
+challenge it. Prefer instead to fix the benchmark, or add one that measures the intended behaviour
+directly. `ConnectionPoolRampRunner` was added for exactly this reason: it keeps the cold pool but
+makes every caller *hold* its connection until all of them have connected, so the pool genuinely needs
+N physical connections and the only variable left is how fast it can open them. That rewards
+concurrent creation instead of penalising it, and it isolates cold start now that the stress runner no
+longer conflates it with checkout cost.
+
+The same principle applies to how a benchmark schedules its workers. A sync `Open()` that has to
+wait blocks whichever thread it runs on, so a pool whose waiter wake-up needs a queued continuation
+stalls when every threadpool thread is already blocked; the wake-up waits on thread injection. On
+the TFMs the perf project builds (net8.0-net10.0) the runtime is told about cooperative blocking and
+compensates quickly, so that stall is tens to a few hundred milliseconds, and that is the only
+expectation these benchmarks validate. On net462 the `Task` wait never notifies the pool, so the
+wake-up falls to starvation detection and hill climbing and is materially slower; the pool carries no
+framework guards and the driver still ships net462, so that path is live but unmeasured here.
+Threadpool threads are the realistic case, because sync database
+calls in ASP.NET run on them, and they are the only configuration in which that stall is visible.
+Benchmarks therefore keep threadpool threads as the default and add dedicated-thread variants
+alongside rather than instead:
+
+- `ConnectionPoolContentionRunner.SteadyStateOpenQueryCloseDedicatedThreads` runs the existing
+  workload on dedicated threads. A regression in both variants points at the pool; a regression in
+  only the threadpool variant points at the waiter wake path.
+- `ConnectionPoolThreadPoolPressureRunner` pins the threadpool floor via `[Params]`, below the worker
+  count (starved) and above it (control), so the effect is reproducible instead of depending on
+  hill-climbing timing.
+
+This failure mode is tail latency, not a shifted median, so compare distributions. Aggregating with
+a per-configuration minimum hides it completely.
+
+Note what those benchmarks are for. Saturating the thread pool with blocked synchronous calls is an
+application configuration problem, not a pool defect: an application should keep its parallelism
+below the thread pool's worker count so newly queued work still runs promptly, and pre-warming the
+thread pool is the application's responsibility rather than the driver's. These benchmarks exist to
+characterise where that boundary sits and to catch it moving, so a delta here is a prompt to check
+the boundary has not shifted rather than a bug to fix.
+
+## Two-pass build model
+
+The `PerformanceTests` project references Microsoft.Data.SqlClient two ways, selected by MSBuild:
+
+- **Current** (default): `ProjectReference` to the in-repo source — the branch under test.
+- **Baseline (package)**: `ReferenceType=Package` turns the reference into a `PackageReference`. Because the
+  repo uses **Central Package Management (CPM)**, the version is pinned with `VersionOverride` via
+  `-p:MdsPackageVersion=<version>` (a plain `Version` is ignored under CPM).
+- **Baseline (source)**: no reference switching at all — the baseline ref's own copy of the perf
+  project is built from `../sqlclient-perf-baseline-src`, keeping its default `ProjectReference` to
+  that ref's driver source. Used by the PR pipeline.
+- **Baseline (switch experiment)**: no second build at all — `--switch-under-test` measures one
+  source tree twice, so the scripts build the `current` variant once and point both passes at it,
+  differing only in the runner config each pass is handed. Used by the experiment pipeline.
+
+The VM's `NuGet.config` exposes only the governed feed, and CPM rejects multiple unmapped sources
+(`NU1507`). The baseline pass therefore restores through a **dedicated single-source config**
+(`perf-baseline-nuget.config`, generated at runtime) pointing only at `https://api.nuget.org/v3/index.json`.
+
+### Benchmarks must compile against the oldest baseline
+
+The baseline pass compiles the **same** `PerformanceTests` sources against the *released* MDS
+package, so a benchmark that calls an API introduced after `baselineVersion` fails that pass with
+`CS1061`. The project defines cumulative `MDS_GE_<major>` constants from `MdsPackageVersion` (see
+`Microsoft.Data.SqlClient.PerformanceTests.csproj`); guard such calls and provide an older
+fallback:
+
+```csharp
+#if MDS_GE_6
+    _ = reader.GetSqlJson(0).Value;   // GetSqlJson was added in MDS 6.0
+#else
+    _ = reader.GetString(0);
+#endif
+```
+
+Project mode, Package mode with no pinned version, and unparsable version strings define every
+constant, since those builds reference a current MDS. Note that a fallback makes the baseline
+measure a **different code path** than the current pass — the affected benchmark's delta is not
+meaningful, so the runner should say so loudly at setup (see `JsonVsVarcharReadRunner`).
+
+## Comparison output
+
+`compare_perf.py` matches benchmarks by `(Type, Method, Parameters)` and reports, per benchmark, the
+baseline/current mean (ms), mean %Δ, allocation %Δ, and a status (`regression` / `improvement` /
+`unchanged` / `new` / `removed`). Outputs:
+
+- `results/comparison/comparison.md` (also copied to `results/summary.md`, which the template
+  attaches as the run summary),
+- `results/comparison/comparison.json` (structured, for tooling).
+
+## Reducing noise
+
+The harness applies a set of harness-owned controls to reduce measurement noise. The lab already
+supplies the isolated dedicated host, the tuned SQL instance, and the disjoint client CPU set
+(`PERF_CLIENT_CPUS`); the run scripts add:
+
+| Control | What the harness does |
+| ------- | --------------------- |
+| Client CPU pin | Pins the benchmark process to `PERF_CLIENT_CPUS` (`taskset` on Linux, `ProcessorAffinity` on Windows). |
+| Fail loud | Preflight `SELECT 1` before any pass, **and** a post-pass guard that fails the run if a pass produced **zero** benchmark results — so an empty comparison can never be reported green. |
+| Warm-up | Touches the target DB in the preflight to warm the buffer pool / plan cache before the first measured benchmark. |
+| Allocator tuning (Linux) | Exports `MALLOC_MMAP_THRESHOLD_=128MiB` and `MALLOC_TRIM_THRESHOLD_=-1` so large-buffer benches (`LargeDataRead`, `SqlBulkCopy`) stop re-`mmap`ing per iteration. |
+| Network tuning (Linux) | Best-effort `sysctl` to widen the ephemeral port range and enable `tcp_tw_reuse` for churn benches (`ConnectionPoolStress`, `ConnectionPoolRamp`, `ConnectionPoolThreadPoolPressure`, `ParallelAsyncConnection`). Never fails the run. |
+| Diagnostics | Writes `results/diagnostics/`: SQL instance config (MAXDOP, memory, affinity, tempdb files, `@@VERSION`), host CPU topology, and per-pass CPU-clock/thermal telemetry (before/after each pass). |
+| Regression gate | `failOnRegression` threads `--fail-on-regression`; only a **candidate-slower** delta past the threshold fails, and in interleaved mode only after best-of-N confirmation. Default off. |
+| Interleaving | In `interleaved` mode the harness runs **one benchmark unit at a time, baseline then candidate back-to-back**, so both sides see the same host state (see below). |
+| Best-of-N confirmation | A unit flagged in the first interleaved pass is re-run `confirmationRuns` times; a regression is **confirmed** only on a strict majority. Unconfirmed flags are reported but never fail the gate. |
+
+### Interleaving + best-of-N (run model)
+
+`benchmarkRunMode` selects how the two variants are measured:
+
+- **`interleaved`** (default) — `interleave_perf.py` orchestrates the run. Both variants are built
+  **once** into separate output dirs (`perf-build-baseline`, `perf-build-current`), then for each
+  benchmark unit the baseline and candidate builds run **back-to-back** before moving to the next
+  unit. Because the same benchmark is measured on both sides within seconds, slow host drift affects
+  both roughly equally and cancels out of the delta. This relies on the `PerformanceTests` runner
+  supporting `PERF_LIST_BENCHMARKS` (enumerate enabled units) and `PERF_BENCHMARK=<unit>` (run a
+  single unit) — see `Program.cs`.
+
+  After the first interleaved pass, only the units containing a flagged regression are re-run
+  `confirmationRuns` times (best-of-N). A regression is **confirmed** only when a strict majority of
+  the N passes agree `(count * 2 > N)`; otherwise it is reported as `regression (unconfirmed)` and
+  does **not** fail the `failOnRegression` gate. `confirmationRuns = 1` disables confirmation.
+
+- **`sequential`** — legacy model: the whole baseline suite runs, then the whole candidate suite,
+  then `compare_perf.py` diffs them. Kept as a fallback; produces the same `results/baseline`,
+  `results/current`, and `results/comparison/` layout so Kusto ingestion is identical.
+
+Both modes emit `results/comparison/comparison.md` + `comparison.json` and copy the markdown to
+`results/summary.md`; interleaved mode adds a **Confirm** column and a confirmed/unconfirmed summary.
+
+### Further tuning (not yet implemented)
+
+- **Release-grade sampling / relaxed thresholds** — tune BenchmarkDotNet job counts and
+  significance thresholds in `runnerconfig.jsonc` / `BenchmarkConfig.cs` now that interleaving and
+  best-of-N are in place.
+
+## Kusto schema & ingestion
+
+Two tables:
+
+- **`PerfRun`** — one row per run (baseline OR current): `DerivedRunId` (PK =
+  `DriverName|CommitHash|PipelineRunId`), driver/machine/agent, `OperatingSystem` (`Windows`/`Linux`),
+  `Architecture` (`x64`/`x86`), `RunType` (`Sequential`/`Interweaved`), pipeline id + build URL,
+  branch + `BranchCategory`, `VersionString`, commit hash/date, `IsComparableBase`, `IngestedAt`.
+  `BranchCategory` buckets the ref as `main`, `release`, `dev`, `feature`, `pull_request` or
+  `other`. The internal ADO mirror's `internal/` prefix is stripped first, so `internal/main` and
+  `internal/release/*` land in the same buckets as their public counterparts.
+- **`PerfBenchmarkResult`** — one row per benchmark: `BenchmarkId` (PK =
+  `DerivedRunId|BenchmarkName|MethodName|ParameterSignature`), timings in **milliseconds**
+  (BenchmarkDotNet reports nanoseconds; values are divided by 1,000,000), percentiles, throughput,
+  allocation, runtime/platform, and `DriverSpecificMetrics` (GC collections, lock contentions, …).
+
+The baseline and current passes share the pipeline run id and (for the current pass) the commit, so
+to keep their `DerivedRunId`s distinct the baseline row uses `CommitHash = v<baselineVersion>` and
+`IsComparableBase = true`; the current row uses the real commit and `IsComparableBase = false` with
+the triggering branch name.
+
+Source = BenchmarkDotNet **JSON "full"** exporter files (`*-report-full.json`). The exporter is
+enabled in `Config/BenchmarkConfig.cs` (`JsonExporter.Full`).
+
+### One-time database setup
+
+Before ingestion can run, create the two tables (`PerfRun`, `PerfBenchmarkResult`) in the target
+database, with columns matching the schema summarized above. No server-side ingestion mappings need
+to be created: `ingest_kusto.py` sends a **self-contained inline JSON column mapping** built from
+each payload's own property names (which are identical to the table's column names), so ingestion
+does not depend on any pre-created named mapping existing on the cluster.
+
+### Authentication
+
+Ingestion runs in an `AzureCLI@2` task using the ADO **ARM service connection**
+(`KustoServiceConnection` from the `ADX Cluster Variables` group). That connection's **service
+principal** must be granted, on the target database:
+
+- **Database Ingestor** — required to queue the ingestion, and
+- **Database Viewer** — required for the post-ingestion verification queries. With Ingestor-only
+  rights the data still lands, but the verify step cannot read it back and logs a warning naming
+  this missing role.
+
+`ingest_kusto.py` authenticates to Kusto with `with_az_cli_authentication` (the service connection
+is already `az login`'d inside the task) and performs a **queued** ingestion against the
+data-management (`ingest-`) endpoint.
+
+### Running before the cluster exists
+
+Ingestion is **conditional**: it only runs when the `enableKustoIngestion` parameter is `true` (the
+default) **and** `KustoClusterUri`, `KustoDatabase` and `KustoServiceConnection` (from the `ADX
+Cluster Variables` group) are all non-empty. Set `enableKustoIngestion` to `false` to opt a run out
+of ingestion explicitly. Until a cluster and service connection are
+configured, the pipeline still runs both passes, produces the comparison, and publishes the
+translated NDJSON as the `perf-kusto-payloads` artifact for manual/backfill ingestion.
+
+## Running the pipeline
+
+1. Open the performance test pipeline in Azure DevOps and select **Run pipeline**.
+2. Choose the branch to benchmark; override `baselineVersion` only if needed. Ingestion is on by
+   default (`enableKustoIngestion`) and uses the `ADX Cluster Variables` group — populate
+   `KustoClusterUri` / `KustoDatabase` / `KustoServiceConnection` there to enable it, leave them empty
+   to skip ingestion, or untick **Ingest results into Kusto** to skip it for a single run.
+3. After the run, review the **run summary** (comparison) and the `perf-results` /
+   `perf-kusto-payloads` artifacts. When a baseline pass ran, the build is tagged
+   **`Baseline <version>`** so the baseline used is visible at a glance in the ADO build list.
+
+### Running the PR pipeline
+
+1. Open the **PR** performance test pipeline (`sqlclient-perf-pr-pipeline.yml`) in Azure DevOps and
+   select **Run pipeline**.
+2. Choose the PR's branch to benchmark. Leave `baselineSourceRef` at `release/7.1` unless the PR
+   targets a different branch. No Kusto configuration is involved — PR results are never ingested.
+3. After the run, review the **run summary** (comparison, labelled `<ref>@<short-sha>`) and the
+   `perf-results` artifact. The build is tagged **`Baseline <ref>`**.
+
+### Running the experiment pipeline
+
+1. Open the **experiment** performance test pipeline (`sqlclient-perf-experiment.yml`) in Azure
+   DevOps and select **Run pipeline**.
+2. Choose the branch whose behaviour you want to measure — `main` to characterise the switch on its
+   own, or a PR branch to characterise it against that change — and pick `switchUnderTest`. There is
+   no baseline selector: the baseline *is* this branch with the switch off. No Kusto configuration is
+   involved; these results are never ingested (see [Why these runs are never ingested into
+   Kusto](#why-these-runs-are-never-ingested-into-kusto)).
+3. After the run, review the **run summary** (comparison, labelled `<Switch>=false`) and the
+   `perf-results` artifact. The build is tagged **`Switch <name>`**.
+
+## Troubleshooting
+
+| Symptom | Likely cause / fix |
+| ------- | ------------------ |
+| `NU1507` during the baseline pass | Multiple NuGet sources under CPM. The baseline uses a single-source config; ensure `perf-baseline-nuget.config` is being passed via `-p:RestoreConfigFile`. |
+| Baseline restore fails to find MDS | `baselineVersion` isn't a published NuGet.org version, or the VM has no outbound access to `api.nuget.org`. |
+| Baseline pass fails to compile: `CS1061 ... does not contain a definition for <member>` | A benchmark calls an MDS API newer than `baselineVersion`. Guard it with the `MDS_GE_<major>` constants and add an older fallback — see [Benchmarks must compile against the oldest baseline](#benchmarks-must-compile-against-the-oldest-baseline). |
+| No comparison / summary | The baseline pass was skipped (empty `baselineVersion` / `baselineSourceRef`) or one pass produced no `*-report-full.json`. |
+| `--switch-under-test is mutually exclusive with --baseline-version and --baseline-source-ref` | A switch experiment was combined with a source baseline. The experiment pipeline never does this; if you are invoking the scripts directly, clear the baseline selector — varying source and config at once makes the delta unattributable. |
+| Switch experiment shows a ~0% delta everywhere | Expected for benchmarks the switch does not touch. If *every* benchmark is flat, check the run log's `Switch A/B` line actually names the switch, and that the switch is one the driver reads at startup via the runner config. |
+| Baseline source ref not found (PR pipeline) | `baselineSourceRef` is not a branch on `origin`, and the fallback `git clone --branch <ref>` of `baselineRepoUrl` also failed (ref does not exist there, or the VM has no outbound access to the remote). The reason git gave is echoed into the build log and saved to `<results>/diagnostics/git-*.log`. |
+| `Fetching baseline ref ... from the checkout's origin` is the last line, then the job stalls | Should no longer happen. The checkout is copied to the VM without credentials (ADO's checkout task defaults to `persistCredentials: false`), so a fetch from an authenticated `origin` used to sit on a `Username for ...` prompt forever. All network git calls now run with `GIT_TERMINAL_PROMPT=0`, no credential helper, stdin closed, and a `GIT_NET_TIMEOUT_SECS` (default 300s) hard timeout, so this fails in under a second and falls back to cloning `baselineRepoUrl`. A fetch failure here is expected and harmless on ADO. |
+| Ingestion step skipped | `enableKustoIngestion` is `false`, or `KustoClusterUri`, `KustoDatabase` or `KustoServiceConnection` (from `ADX Cluster Variables`) is empty (expected until the cluster is provisioned). |
+| Ingestion auth error | The service connection's SP lacks **Database Ingestor** on the target database. |
+| "Kusto ingestion was queued, but the ingestion principal is not authorized to query the database" | The SP has **Database Ingestor** but not **Database Viewer**. Ingestion succeeded; grant **Database Viewer** so the verify step can confirm the rows landed. |
+| `Kusto ingestion not yet queryable after Ns ... no ingestion failures were reported` (warning, step passes) | Expected, harmless: queued ingestion is asynchronous and small perf payloads can take longer than the verify window to become queryable. The step **warns and passes** because `.show ingestion failures` is clean, so the rows will land shortly. The step only **fails** when `.show ingestion failures` actually reports failures — in that case confirm the `PerfRun` / `PerfBenchmarkResult` tables exist with columns matching the schema above (a schema/column-name mismatch is the usual cause; the self-contained inline JSON mapping rules out a missing server-side named mapping). |
+| Benchmarks not CPU-pinned | `PERF_CLIENT_CPUS` was not injected, or `taskset` is unavailable on the VM. |

+"""Ingest translated perf-results NDJSON files into Azure Data Explorer (Kusto).
+
+Runs on the pipeline agent inside an ``AzureCLI@2`` task so that the Azure DevOps
+service connection's service principal is already logged in via ``az``.  The
+script therefore authenticates to Kusto with *az CLI* credentials and performs a
+queued ingestion of the PerfRun and PerfBenchmarkResult NDJSON files produced by
+``perf_to_kusto.py``.
+
+Queued ingestion is asynchronous: ``ingest_from_file`` only *enqueues* the data
+and returns success even when the data later fails to land (e.g. a schema
+mismatch, or a *missing* server-side ingestion mapping - which the data-management
+service silently retries for ~2 days before recording a failure).  Those failures
+surface only in Kusto's ingestion failure system, so the pipeline step used to go
+green (or hang) while the database stayed empty.  To avoid that this script:
+
+  * sends a **self-contained inline JSON column mapping** (built from the payload's
+    own property names, which match the target table's columns) instead of
+    referencing a named server-side mapping that must be pre-created on the cluster,
+  * sets ``flush_immediately`` so the data-management service seals the batch
+    right away instead of waiting out the (default 5 minute) batching window, and
+  * verifies, after queuing, that the expected rows actually became queryable --
+    polling the target tables and, on timeout, printing ``.show ingestion
+    failures`` so the real error is visible in the build log (and failing the
+    step).
+
+Requires the ``azure-kusto-ingest`` package (``pip install azure-kusto-data
+azure-kusto-ingest``); the pipeline step installs it before invoking this script.

+"""Interleaved, best-of-N benchmark orchestrator for the SqlClient perf pipeline.
+
+Implements the two structural noise-reduction controls from InternalDriverTools
+wiki 339 ("Reducing Noise in Performance Tests"):
+
+* **Interleaving (§2.2 / §2.3)** — instead of running the whole baseline suite and
+  then the whole candidate suite (so a given benchmark is measured tens of minutes
+  apart), this runs *one benchmark unit at a time*, executing the baseline build and
+  the candidate build back-to-back for that unit before moving on.  Any slow host
+  drift then affects both sides of each comparison roughly equally.
+
+* **Best-of-N confirmation (§2.6)** — a single measurement can flag a regression
+  purely from noise.  After the first interleaved pass, only the units that showed a
+  regression are re-run N-1 more times (still interleaved); a regression is
+  *confirmed* only when a strict majority of the N passes agree.  This is what makes
+  the ``--fail-on-regression`` gate trustworthy.
+
+The benchmark executable is the ``PerformanceTests`` app built two ways (same test
+sources, different Microsoft.Data.SqlClient reference).  It understands two env vars
+added for this orchestrator:
+
+* ``PERF_LIST_BENCHMARKS`` — print the enabled unit names and exit.
+* ``PERF_BENCHMARK=<Name>`` — run only that unit.
+
+Only the Python standard library is used so it runs on the perf VM unchanged.

+#
+# Responsibilities:
+#   1. Install the .NET SDK pinned by the repo's global.json (plus the runtime for the target TFM).
+#   2. Create the perf database on the VM's SQL Server (the benchmark runners create tables but not
+#      the database).
+#   3. Inject the VM's SQL Server connection string into the benchmark runner config.
+#   4. Pin the benchmark client to the reserved CPU set (PERF_CLIENT_CPUS) so it does not contend
+#      with SQL Server (which is pinned to the disjoint PERF_SQL_CPUS set).
+#   5. Run the BenchmarkDotNet performance tests.
+#   6. Collect the BenchmarkDotNet artifacts into the results sub-directory.
+#
+# Environment variables injected by the template (see wiki "Performance Test Automation"):

+# SqlClient Switch Experiment Performance pipeline.
+#
+# Third sibling of sqlclient-perf-pipeline.yml and sqlclient-perf-pr-pipeline.yml.  It runs the SAME
+# benchmarks, on the SAME Perf Test Lab extends template (v1/Perf.Test.Job.yml@PerfTemplates),
+# through the SAME on-VM scripts.  What differs is the QUESTION it answers:
+#
+#   * perf pipeline     - "has this branch regressed against a released package?"   (source varies)
+#   * perf-pr pipeline  - "has this PR regressed the branch it merges into?"        (source varies)
+#   * THIS pipeline     - "what does this AppContext/runner switch cost or buy?"    (CONFIG varies)
+#
+# Both passes here build the SAME source (whatever branch the run is queued on); only ONE runner
+# config switch differs between them - baseline runs it OFF, current runs it ON.  Two separate
+# processes are required because these switches are latched process-wide (e.g. UseConnectionPoolV2 is
+# read and cached the first time a connection pool is created), so they cannot be toggled between
+# benchmarks inside a single run.  Queue this pipeline on a PR branch to ask "what does the switch do
+# to my change?", or on main to ask "what does the switch do to main?".
+#
+#   * No Kusto - switch-experiment results are NEVER ingested into the perf database, and this is why
+#                the mode lives in its own pipeline rather than as a flag on the other two:
+#                  - both PerfRun rows would share one DerivedRunId (driver|commit|pipelineRunId),
+#                    because both passes are the same commit in the same pipeline run;
+#                  - PerfRun.Config is stamped once per run, so the two rows could not record the
+#                    differing switch values that are the entire point of the experiment;
+#                  - nothing marks a row as an experiment, so the switch-ON pass would be
+#                    indistinguishable from an ordinary measurement of the branch and would distort
+#                    the very trends the other two pipelines exist to protect.
+#                Having no ADX variable group and no translate/ingest steps in this file makes that
+#                exclusion structural rather than a conditional someone can flip by accident.
+#                The comparison report and the raw BenchmarkDotNet artifacts are still published.
+#
+# Everything else - platform/VM provisioning, benchmark run model, noise controls - is identical to
+# the other two pipelines; see eng/pipelines/perf/README.md.

+# The template owns the full run lifecycle (SSH key generation, dedicated-host VM provisioning, test
+# execution over SSH, result collection, and teardown).  All this pipeline supplies is:

+#   * the source directory to copy to the VM (testRootDir),
+#   * the entry-point script to execute on the VM (testScript + testScriptArgs),
+#   * the results subfolder to copy back (testResultsSubDir), and
+#   * optional post-test steps to surface the results.
+#
+# The on-VM script (eng/pipelines/perf/scripts/run-perf-tests.*) installs the .NET SDK, creates the
+# perf database, injects the VM's SQL Server connection string into the benchmark runner config,
+# pins the client to the reserved CPU set, runs the benchmarks, and collects the BenchmarkDotNet

+# Sibling of sqlclient-perf-pipeline.yml: it runs the SAME benchmarks, on the SAME Perf Test Lab
+# extends template (v1/Perf.Test.Job.yml@PerfTemplates), with the SAME configuration options.  The
+# only differences are what it compares against and what it does with the results:
+#
+#   * Baseline    - the branch the run is queued on ("current") is compared against the SOURCE of
+#                   another ref of this repository (by default 'release/7.1'), NOT a released NuGet
+#                   package.  Both sides are therefore built from source, which is what a PR author
+#                   wants to know: "does my change regress the branch I am merging into?"
+#   * No Kusto    - results are never ingested into the perf database (a PR run measures an unmerged
+#                   branch, so its numbers must not pollute the historical trend).  The comparison
+#                   and the raw BenchmarkDotNet artifacts are still published as pipeline artifacts.

+.SYNOPSIS
+    Installs the docker CLI on an Intel macOS agent from a Homebrew bottle.
+
+.DESCRIPTION
+    Homebrew ships no Intel macOS bottle for the current docker formula, so
+    'brew install docker' compiles the CLI - and builds Go in order to do it -
+    which takes minutes and routinely exhausts the pipeline step timeout.
+
+    This installs the newest docker version that *is* bottled for Intel macOS,
+    read from Homebrew's own OCI registry on ghcr.io. Bottles are
+    content-addressed, so the download is verified against the digest the
+    registry advertises rather than a checksum pinned here that someone has to
+    remember to bump. Nothing is downloaded from outside Homebrew, and the
+    result is exactly what 'brew install' would have produced.
+
+    Only the docker CLI is handled this way. colima and lima still install
+    through brew: their bottles carry payloads outside bin/ and colima depends
+    on lima at runtime, so neither can be installed by lifting a single binary.
+
+.PARAMETER DestinationPath
+    Directory the docker binary is written to. Prepended to PATH for subsequent
+    pipeline steps.
+
+.NOTES
+    Intel macOS only. On any other architecture this fails rather than
+    installing a binary the agent cannot run.

+<#
+.SYNOPSIS
+    Publishes OneLocBuild-generated localized resource files to GitHub as a
+    single, continuously-updated pull request.
+
+.DESCRIPTION
+    The Localization-CI pipeline regenerates the localized `Strings.*.resx`
+    files on every scheduled run. Because the generated content is identical
+    until a previous localization PR is merged, naively opening a new PR per
+    run produces a pile of byte-for-byte duplicate PRs.
+
+    This script makes the publish step idempotent:
+
+      1. Clones the target GitHub repository at the base branch.
+      2. Copies the freshly generated localized resource files into the clone.
+      3. If the content matches the base branch, exits without doing anything.
+      4. Otherwise commits onto a *stable* branch name, force-pushes it, and
+         reuses the existing open pull request if one is already present.
+
+    The net effect is at most one open localization PR at any time. Subsequent
+    runs refresh that PR in place instead of opening another one.
+
+.PARAMETER GitHubRepository
+    The target repository in "owner/repo" form. A trailing ".git" is tolerated
+    so the existing $(GitHubRepository) pipeline variable can be passed as-is.
+
+.PARAMETER AccessToken
+    A GitHub token with "contents: write" and "pull requests: write" on the
+    target repository. Defaults to the GITHUB_TOKEN environment variable.
+
+.PARAMETER SourceDirectory
+    The directory holding the OneLocBuild output. Localized files are resolved
+    relative to this path using ResourcesPath. Defaults to the current
+    directory.
+
+.PARAMETER WorkingDirectory
+    The directory the target repository is cloned into. Defaults to a new
+    "loc-pr-<guid>" folder under the system temp path, which is removed when
+    the script finishes.
+
+.PARAMETER BaseBranch
+    The branch the pull request targets. Defaults to "main".
+
+.PARAMETER BranchName
+    The stable branch the localized files are published to. Reusing one branch
+    name across runs is what allows the pull request to be reused. Defaults to
+    "dev/automation/onelocbuild".
+
+.PARAMETER ResourcesPath
+    Repository-relative path to the resources folder. Defaults to the
+    Microsoft.Data.SqlClient resources folder.
+
+.PARAMETER ResourceFilePattern
+    Filename pattern for the localized resource files to publish. Defaults to
+    "Strings.*.resx", which matches the localized files but not the English
+    "Strings.resx" source.
+
+.PARAMETER DryRun
+    Performs every read-only step - clone, copy, change detection and the
+    existing-pull-request lookup - but does not push the branch and does not
+    create or update a pull request. Use this to validate pipeline wiring
+    (paths, token scopes, OneLocBuild output) without publishing anything.
+
+.NOTES
+    Intended to be invoked from the internal Localization-CI pipeline. It is
+    safe to re-run: with no localization changes pending it is a no-op, and
+    with changes pending it converges on a single open pull request.

+    Syncs a GitHub branch into an Azure DevOps repository via a pull request.
+
+.DESCRIPTION
+    This script fetches the latest commits from a public GitHub repository,
+    force-pushes them to a sync branch in the ADO repo, then creates or updates
+    a pull request targeting the specified ADO branch.
+
+    If there are no new commits (the branches are already in sync), the script
+    exits cleanly with no changes.
+
+.PARAMETER GitHubRepoUrl
+    The HTTPS clone URL of the public GitHub repository.
+
+.PARAMETER GitHubBranch
+    The branch to sync from GitHub (e.g. "main").
+
+.PARAMETER TargetBranch
+    The ADO branch the PR should target (e.g. "internal/main").
+
+.PARAMETER SyncBranchName
+    The ADO branch name to push GitHub commits to (e.g. "dev/autosync/github-main").
+
+.PARAMETER AdoOrgUrl
+    The Azure DevOps organization URL (e.g. "https://dev.azure.com/org/").
+
+.PARAMETER AdoProject
+    The Azure DevOps project name.
+
+.PARAMETER AdoRepoName
+    The Azure DevOps repository name.
+
+.PARAMETER AccessToken
+    The access token for ADO REST API and git push operations.
+    Defaults to the SYSTEM_ACCESSTOKEN environment variable.
+
+.NOTES
+    This pipeline is intended to be run only in the internal ADO.Net project.
+    It must never be run in the Public project or triggered by changes in GitHub.

+

+# Pipeline Script Tests
+
+Pester tests for the PowerShell helpers under `eng/pipelines/scripts/`.
+
+## Prerequisites
+
+These tests require **Pester v5 or later**:
+
+```powershell
+Install-Module Pester -MinimumVersion 5.0 -Scope CurrentUser -Force -SkipPublisherCheck
+```
+
+## Running the tests
+
+```powershell
+Import-Module Pester -MinimumVersion 5.0
+Invoke-Pester ./eng/pipelines/scripts/tests/
+```
+
+Add `-Output Detailed` to see per-test results.
+
+## Test files
+
+| File | Covers |
+| ---- | ------ |
+| `Open-LocalizationPr.Tests.ps1` | `Open-LocalizationPr.ps1` — de-duplication of the scheduled localization pull request. |
+| `Install-DockerCli.macos.Tests.ps1` | `Install-DockerCli.macos.ps1` — Homebrew bottle selection for the macOS docker CLI. |
+
+`git`, `tar`, `Invoke-RestMethod` and `Invoke-WebRequest` are mocked, so the
+tests never touch the network or a real repository.

-<#
-.SYNOPSIS
-  This script installs dotnet SDKs and Runtimes for ARM64.
-
-.DESCRIPTION
-  Special handling is required for ARM64 due to a bug in UseDotNet@2:
- 
-  [BUG]: UseDotNet@2 task installs x86 build
-  https://github.com/microsoft/azure-pipelines-tasks/issues/20300
- 
-  The downloaded dotnet-install.ps1 script is kept in the $InstallDir to avoid
-  downloading it multiple times during the pipeline job.
- 
-  The following environment variables are set for subsequent steps in the pipeline:
- 
-    DOTNET_ROOT: Set to $InstallDir.
-    PATH: $DOTNET_ROOT is prepended to the PATH environment variable.
-
-.PARAMETER Debug
-  True to emit debug messages.  Default is false.
-
-.PARAMETER DryRun
-  True to perform a dry run of the installation.  Default is false.
-
-.PARAMETER GlobalJson
-  The path to the global.json file that specifies the exact SDK version to
-  install.  Default is 'global.json'.
-
-.PARAMETER InstallDir
-  The directory to install the SDKs and Runtimes into, typically the
-  pipeline's $(Agent.ToolsDirectory)/dotnet directory.
-
-  The dotnet-install.ps1 script is downloaded into this directory if it is not
-  already present.
-
-  Default is '.'.
-
-.PARAMETER Runtimes
-  The versions of the .NET Runtimes to install.  These must be in the runtime
-  channel format of X.Y expected by the dotnet-install.ps1 script.  Default is
-  an empty array.

+# Release Notes
+
+## Stable Release 6.1.5 - 2026-04-27
+
+This update brings the following changes since the [6.1.4](6.1.4.md) release:
+
+### Fixed
+
+- Fixed a connection performance regression where SPN (Service Principal Name) generation was triggered for non-integrated authentication modes (e.g., SQL authentication) on the native SNI path, causing unnecessary DNS lookups and significantly slower connection times.
+  ([#3523](https://github.com/dotnet/SqlClient/issues/3523), [#3946](https://github.com/dotnet/SqlClient/pull/3946))
+
+- Fixed `ExecuteScalar` to properly propagate errors when the server sends data followed by an error token. Previously, errors such as conversion failures during `WHERE` clause evaluation were silently consumed during `SqlDataReader.Close()` instead of being thrown to the caller, which could result in transactions being unexpectedly zombied.
+  ([#3736](https://github.com/dotnet/SqlClient/issues/3736), [#3947](https://github.com/dotnet/SqlClient/pull/3947))
+
+- Fixed `SqlDataReader.GetFieldType` and `SqlDataReader.GetProviderSpecificFieldType` to return the correct type (`SqlVector<float>`) for vector float32 columns. Previously, these methods did not follow the same type-resolution logic as `GetValue`, returning an incorrect type for vector columns.
+  ([#4104](https://github.com/dotnet/SqlClient/issues/4104), [#4151](https://github.com/dotnet/SqlClient/pull/4151))
+

+# Release Notes
+
+## Stable Release 6.1.6 - 2026-06-24
+
+This update brings the following changes since the [6.1.5](6.1.5.md) release:
+
+### Added
+
+#### WAM broker support for the supported Entra ID authentication modes (Windows only)
+
+*What Changed:*
+
+- Added support for the [Web Account Manager (WAM)](https://learn.microsoft.com/entra/msal/dotnet/acquiring-tokens/desktop-mobile/wam) broker for the supported Microsoft Entra ID authentication modes. A new `ActiveDirectoryAuthenticationProviderOptions` options bag and a corresponding `ActiveDirectoryAuthenticationProvider(ActiveDirectoryAuthenticationProviderOptions options)` constructor were introduced, exposing a `UseWamBroker` property (alongside `ApplicationClientId` and `DeviceCodeFlowCallback`).
+  ([#4288](https://github.com/dotnet/SqlClient/pull/4288), [#4387](https://github.com/dotnet/SqlClient/pull/4387))
+- Added a cross-platform `SetParentActivityOrWindowFunc(Func<object> parentActivityOrWindowFunc)` method so callers can supply a parent window handle on Windows or a parent `Activity`/`UIViewController` on Android/iOS/MAUI.
+
+*Who Benefits:*
+
+- Applications using `ActiveDirectoryInteractive` and other supported Entra ID authentication modes on Windows benefit from the WAM broker's improved security (tokens are brokered by the OS), single sign-on with the logged-in Windows account, and support for Conditional Access and Windows Hello.
+
+*Impact:*
+
+- When you supply your `ApplicationClientId`, WAM is opt-in via `ActiveDirectoryAuthenticationProviderOptions.UseWamBroker`. Consider enabling it when you want OS-brokered tokens, single sign-on with the signed-in Windows account, Windows Hello, and Conditional Access support.
+- `UseWamBroker` is a **Windows-only** setting and has no effect on non-Windows platforms, where interactive Entra ID flows always use the system browser.
+- Prefer the new options-bag constructor over the positional-argument overloads in new code.
+
+```c#
+var options = new ActiveDirectoryAuthenticationProviderOptions
+{
+    ApplicationClientId = "<your-app-client-id>",
+    // Enable WAM (Windows only) for OS-brokered tokens, SSO, Windows Hello, and Conditional Access.
+    UseWamBroker = true,
+};
+var provider = new ActiveDirectoryAuthenticationProvider(options);
+// Supply the parent window/activity that owns the interactive sign-in prompt.
+provider.SetParentActivityOrWindowFunc(() => parentWindowHandle);
+SqlAuthenticationProvider.SetProvider(SqlAuthenticationMethod.ActiveDirectoryInteractive, provider);
+```
+
+
+### Changed
+
+#### Hardened TDS token parsing with data-length bounds checks
+
+*What Changed:*
+
+- Added bounds checking when parsing TDS token data lengths. The parser now validates the declared length of incoming token data against the available buffer before reading, rejecting malformed or out-of-range length values instead of reading past the intended boundary.
+  ([#4340](https://github.com/dotnet/SqlClient/pull/4340), [#4359](https://github.com/dotnet/SqlClient/pull/4359))
+
+*Who Benefits:*
+
+- All consumers benefit from improved resilience against malformed or hostile TDS responses. A server (or man-in-the-middle) sending an invalid token length can no longer drive the parser to read beyond the declared payload.
+
+*Impact:*
+
+- Connections that previously parsed malformed token streams loosely will now fail fast with a clear protocol error. Well-behaved SQL Server responses are unaffected.
+
+#### Other changes
+
+- Updated dependencies ([#4387](https://github.com/dotnet/SqlClient/pull/4387)):
+  - Updated `Microsoft.Identity.Client` to 4.84.2 (was 4.80.0)
+  - Added `Microsoft.Identity.Client.Broker` 4.84.2
+
+### Fixed
+
+- Fixed a `NullReferenceException` in `SqlDataReader.GetChars` on the PLP + `CommandBehavior.SequentialAccess` path when a `null` buffer was passed together with a negative `bufferIndex`. The call now correctly throws `ArgumentOutOfRangeException` for the `bufferIndex` parameter.
+  ([#4159](https://github.com/dotnet/SqlClient/pull/4159), [#4205](https://github.com/dotnet/SqlClient/pull/4205))
+
+- Fixed column master key (CMK) signature verification caching where `GetSignatureVerificationResult` returned whether the cache key existed rather than the cached value itself. Once a signature verification failure was cached as `false`, subsequent lookups incorrectly returned `true`, causing the caller to skip re-verification and treat the column master key as having a valid signature.
+  ([#4339](https://github.com/dotnet/SqlClient/pull/4339), [#4356](https://github.com/dotnet/SqlClient/pull/4356))

+# Release Notes
+
+## Stable Release 6.1.7 - 2026-09-10
+
+This update brings the following changes since the [6.1.6](6.1.6.md) release:
+
+### Changed
+
+- Updated the `Microsoft.Data.SqlClient.SNI` and `Microsoft.Data.SqlClient.SNI.runtime` dependencies to 6.0.3 (was 6.0.2).
+  ([#4598](https://github.com/dotnet/SqlClient/pull/4598))
+
+### Fixed
+
+- Fixed `ServerCertificate` validation on the managed SNI path so the configured certificate is compared against the server certificate even when the server certificate passes chain and host-name validation. When certificate validation is enabled, a missing, unreadable, or invalid certificate file, a certificate mismatch, or a missing server certificate now causes the TLS handshake to fail instead of bypassing the configured certificate check. (net8.0/net9.0 only)
+  ([#4445](https://github.com/dotnet/SqlClient/pull/4445), [#4584](https://github.com/dotnet/SqlClient/pull/4584))
+
+- Fixed Always Encrypted VSM/HGS enclave attestation to verify that the enclave public key used to establish a session matches the key committed to by the signed attestation report. Missing, malformed, or mismatched key-binding data now causes attestation to fail before the session secret is derived.
+  ([#4532](https://github.com/dotnet/SqlClient/pull/4532), [#4552](https://github.com/dotnet/SqlClient/pull/4552))
+
+- Fixed `SqlConnection.AccessTokenCallback` not disabling Transparent Network IP Resolution by default, making it consistent with `SqlConnection.AccessToken`. An explicitly configured `TransparentNetworkIPResolution` connection-string value still takes precedence. (net462 only)
+  ([#4520](https://github.com/dotnet/SqlClient/pull/4520), [#4560](https://github.com/dotnet/SqlClient/pull/4560))
+
+- Fixed token authentication state handling so clearing `SqlConnection.AccessToken` preserves an existing `AccessTokenCallback` in the connection pool key, and clearing `AccessTokenCallback` preserves an existing `AccessToken`. Callback-based authentication now also follows the same prelogin server-certificate validation rules as an explicitly supplied access token.
+  ([#4520](https://github.com/dotnet/SqlClient/pull/4520), [#4560](https://github.com/dotnet/SqlClient/pull/4560))
+
+- Fixed configurable retry logic installing a permanent, process-wide assembly-resolution handler that could interfere with unrelated assembly loading. The handler is now active only while an explicitly configured custom retry provider is resolved and constructed, and probes `AppContext.BaseDirectory` instead of the current working directory. Place custom retry assemblies in the application base directory; dependencies loaded after provider construction must be resolvable through normal application dependency resolution or an application-provided handler. (net8.0/net9.0 only)
+  ([#2214](https://github.com/dotnet/SqlClient/issues/2214), [#4547](https://github.com/dotnet/SqlClient/pull/4547), [#4664](https://github.com/dotnet/SqlClient/pull/4664))

+# Release Notes
+
+## Stable Release 7.0.0 - 2026-03-17
+
+This is the general availability release of **Microsoft.Data.SqlClient 7.0**, a major milestone for the .NET data provider for SQL Server.

+
+## Cumulative Changes Since [6.1](../6.1/README.md)
+
+This section summarizes all changes across the 7.0 preview cycle for users upgrading from the latest 6.1 stable release.
+
+### Changed
+
+#### Azure Dependencies Removed from Core Package
+
+*What Changed:*
+
+- The core `Microsoft.Data.SqlClient` package no longer depends on `Azure.Core`, `Azure.Identity`, or their transitive dependencies (e.g., `Microsoft.Identity.Client`, `Microsoft.Web.WebView2`). Azure Active Directory / Entra ID authentication functionality (`ActiveDirectoryAuthenticationProvider` and related types) has been extracted into a new `Microsoft.Data.SqlClient.Extensions.Azure` package.
+  ([#1108](https://github.com/dotnet/SqlClient/issues/1108),
+   [#3680](https://github.com/dotnet/SqlClient/pull/3680),
+   [#3902](https://github.com/dotnet/SqlClient/pull/3902),
+   [#3904](https://github.com/dotnet/SqlClient/pull/3904),
+   [#3908](https://github.com/dotnet/SqlClient/pull/3908),
+   [#3917](https://github.com/dotnet/SqlClient/pull/3917),
+   [#3982](https://github.com/dotnet/SqlClient/pull/3982),
+   [#3978](https://github.com/dotnet/SqlClient/pull/3978),
+   [#3986](https://github.com/dotnet/SqlClient/pull/3986))
+- Two additional packages were introduced to support this separation: `Microsoft.Data.SqlClient.Extensions.Abstractions` (shared types between the core driver and extensions) and `Microsoft.Data.SqlClient.Internal.Logging` (shared ETW tracing infrastructure).
+  ([#3626](https://github.com/dotnet/SqlClient/pull/3626),
+   [#3628](https://github.com/dotnet/SqlClient/pull/3628),
+   [#3967](https://github.com/dotnet/SqlClient/pull/3967),
+   [#4038](https://github.com/dotnet/SqlClient/pull/4038))
+
+*Who Benefits:*
+
+- All users benefit from a significantly lighter core package. Previously, the Azure dependency chain pulled in numerous assemblies even for applications that only needed basic SQL Server connectivity. This was the [most upvoted open issue](https://github.com/dotnet/SqlClient/issues/1108) in the repository.
+- Users who do not use Entra ID authentication no longer carry Azure-related assemblies in their build output.
+- Users who do use Entra ID authentication can now manage Azure dependency versions independently from the core driver.
+
+*Impact:*
+
+- Applications using Entra ID authentication (e.g., `ActiveDirectoryInteractive`, `ActiveDirectoryDefault`, `ActiveDirectoryManagedIdentity`, etc.) must now install the `Microsoft.Data.SqlClient.Extensions.Azure` NuGet package separately:
+
+```
+dotnet add package Microsoft.Data.SqlClient.Extensions.Azure
+```
+
+- No code changes are required beyond adding the package reference.
+- If an Entra ID authentication method is used without the Azure package installed, the driver now provides an actionable error message guiding users to install the correct package.
+
+### Added
+
+#### Pluggable Authentication with SspiContextProvider
+
+*What Changed:*
+
+- Added a public `SspiContextProvider` property on `SqlConnection`, completing the SSPI extensibility work begun in 6.1.0. Applications can now supply a custom SSPI context provider for integrated authentication, enabling custom Kerberos ticket negotiation and NTLM username/password authentication scenarios.
+  ([#2253](https://github.com/dotnet/SqlClient/issues/2253),
+   [#2494](https://github.com/dotnet/SqlClient/pull/2494))
+
+*Who Benefits:*
+
+- Users authenticating across untrusted domains, non-domain-joined machines, or cross-platform environments where configuring integrated authentication is difficult.
+- Users running in containers who need manual Kerberos negotiation without deploying sidecars or external ticket-refresh mechanisms.
+- Users who need NTLM username/password authentication to SQL Server, which the driver does not provide natively.
+
+*Impact:*
+
+- Applications can set a custom `SspiContextProvider` on `SqlConnection` before opening the connection:
+
+```c#
+var connection = new SqlConnection(connectionString);
+connection.SspiContextProvider = new MyKerberosProvider();
+connection.Open();
+```
+
+- The provider handles the authentication token exchange during integrated authentication. Existing authentication behavior is unchanged when no custom provider is set. See [SspiContextProvider_CustomProvider.cs](../../doc/samples/SspiContextProvider_CustomProvider.cs) for a sample implementation.
+- **Note:** The `SspiContextProvider` is part of the connection pool key. Care should be taken when using this property to ensure the implementation returns a stable identity per resource.
+
+#### Async Read Performance: Packet Multiplexing (Preview)
+
+*What Changed:*
+
+- Continued refinement of packet multiplexing with bug fixes and stability improvements since 6.1.0, plus new app context switches for opt-in control.
+  ([#3534](https://github.com/dotnet/SqlClient/pull/3534),
+   [#3537](https://github.com/dotnet/SqlClient/pull/3537),
+   [#3605](https://github.com/dotnet/SqlClient/pull/3605))
+
+*Who Benefits:*
+
+- Applications performing large async reads (`ExecuteReaderAsync` with big result sets, streaming scenarios, or bulk data retrieval).
+
+*Impact:*
+
+- Packet multiplexing ships behind two opt-in feature switches:
+
+```c#
+AppContext.SetSwitch("Switch.Microsoft.Data.SqlClient.UseCompatibilityAsyncBehaviour", false);
+AppContext.SetSwitch("Switch.Microsoft.Data.SqlClient.UseCompatibilityProcessSni", false);
+```
+
+- Setting both switches to `false` enables the new async processing path. By default, the driver uses the existing (compatible) behavior.
+
+#### Enhanced Routing Support
+
+*What Changed:*
+
+- Added support for enhanced routing, a TDS feature that allows the server to redirect connections to a specific server *and* database during login.
+  ([#3641](https://github.com/dotnet/SqlClient/issues/3641),
+   [#3969](https://github.com/dotnet/SqlClient/pull/3969),
+   [#3970](https://github.com/dotnet/SqlClient/pull/3970),
+   [#3973](https://github.com/dotnet/SqlClient/pull/3973))
+
+*Who Benefits:*
+
+- Users connecting to Azure SQL Hyperscale environments that use named read replicas and gateway-based load balancing.
+
+*Impact:*
+
+- Enhanced routing is negotiated automatically during login when the server supports it. No application code changes are required.
+
+#### Support for .NET 10
+
+*What Changed:*
+
+- Updated pipelines and test suites to compile the driver using the .NET 10 SDK.
+  ([#3686](https://github.com/dotnet/SqlClient/pull/3686))
+
+*Who Benefits:*
+
+- Developers targeting .NET 10 on day one.
+
+*Impact:*
+
+- SqlClient 7.0 compiles and tests against .NET 10, ensuring compatibility.
+
+#### Strongly-Typed Diagnostic Events on .NET Framework
+
+*What Changed:*
+
+- Enabled `SqlClientDiagnosticListener` for `SqlCommand` on .NET Framework, closing a long-standing observability gap where diagnostic events were previously only emitted on .NET Core.
+  ([#3658](https://github.com/dotnet/SqlClient/pull/3658))
+
+- Brought the 15 strongly-typed diagnostic event classes in the `Microsoft.Data.SqlClient.Diagnostics` namespace — originally introduced for .NET Core in 6.0 — to .NET Framework as part of the codebase merge. Both platforms now use the same strongly-typed event model. The types cover command, connection, and transaction lifecycle events:
+  - `SqlClientCommandBefore`, `SqlClientCommandAfter`, `SqlClientCommandError`
+  - `SqlClientConnectionOpenBefore`, `SqlClientConnectionOpenAfter`, `SqlClientConnectionOpenError`
+  - `SqlClientConnectionCloseBefore`, `SqlClientConnectionCloseAfter`, `SqlClientConnectionCloseError`
+  - `SqlClientTransactionCommitBefore`, `SqlClientTransactionCommitAfter`, `SqlClientTransactionCommitError`
+  - `SqlClientTransactionRollbackBefore`, `SqlClientTransactionRollbackAfter`, `SqlClientTransactionRollbackError`
+
+  ([#3493](https://github.com/dotnet/SqlClient/pull/3493))
+
+*Who Benefits:*
+
+- .NET Framework users subscribing to `SqlClientDiagnosticListener` events for observability, distributed tracing, or custom telemetry. These users now have parity with .NET Core, gaining IntelliSense, compile-time safety, and eliminating the need to access diagnostic payloads via reflection or dictionary lookups.
+
+*Impact:*
+
+- On .NET Framework, `SqlCommand` now emits the same diagnostic events that were previously only available on .NET Core. Subscribers to `DiagnosticListener` events (e.g., `Microsoft.Data.SqlClient.WriteCommandBefore`) receive the strongly-typed objects:
+
+```c#
+listener.Subscribe(new Observer<KeyValuePair<string, object?>>(kvp =>
+{
+    if (kvp.Value is SqlClientCommandBefore before)
+    {
+        Console.WriteLine($"Executing: {before.Command.CommandText}");
+    }
+}));
+```
+
+- The types implement `IReadOnlyList<KeyValuePair<string, object>>` for backward compatibility with code that iterates properties generically.
+
+#### Other Additions
+
+- Added `SqlConfigurableRetryFactory.BaselineTransientErrors` static property exposing the default transient error codes list as a `ReadOnlyCollection<int>`, making it easier to extend the default list with application-specific error codes.
+  ([#3903](https://github.com/dotnet/SqlClient/pull/3903))
+
+- Added app context switch `Switch.Microsoft.Data.SqlClient.EnableMultiSubnetFailoverByDefault` to set `MultiSubnetFailover=true` globally without modifying connection strings.
+  ([#3841](https://github.com/dotnet/SqlClient/pull/3841))
+
+- Added app context switch `Switch.Microsoft.Data.SqlClient.IgnoreServerProvidedFailoverPartner` to let the client ignore server-provided failover partner info in Basic Availability Groups.
+  ([#3625](https://github.com/dotnet/SqlClient/pull/3625))
+
+- Enabled User Agent Feature Extension (opt-in via `Switch.Microsoft.Data.SqlClient.EnableUserAgent`).
+  ([#3606](https://github.com/dotnet/SqlClient/pull/3606))
+
+### Changed
+
+#### Deprecation of `SqlAuthenticationMethod.ActiveDirectoryPassword`
+
+*What Changed:*
+
+- `SqlAuthenticationMethod.ActiveDirectoryPassword` (the ROPC flow) is now marked `[Obsolete]` and will generate compiler warnings. This aligns with Microsoft's move toward [mandatory multifactor authentication](https://learn.microsoft.com/entra/identity/authentication/concept-mandatory-multifactor-authentication).
+  ([#3671](https://github.com/dotnet/SqlClient/pull/3671))
+
+*Who Benefits:*
+
+- Teams moving toward stronger, passwordless or MFA-compliant authentication.
+
+*Impact:*
+
+- If you use `Authentication=Active Directory Password`, migrate to a supported alternative:
+
+| Scenario | Recommended Authentication |
+|----------|---------------------------|
+| Interactive / desktop apps | `Active Directory Interactive` |
+| Service-to-service | `Active Directory Service Principal` |
+| Azure-hosted workloads | `Active Directory Managed Identity` |
+| Developer / CI environments | `Active Directory Default` |
+
+- See [Connect to Azure SQL with Microsoft Entra authentication](https://learn.microsoft.com/sql/connect/ado-net/sql/azure-active-directory-authentication) for more information.
+
+#### Breaking Changes
+
+- Reverted public visibility of internal interop enums (`IoControlCodeAccess` and `IoControlTransferType`) that were accidentally made public during the project merge.
+  ([#3900](https://github.com/dotnet/SqlClient/pull/3900))
+
+#### Other Changes
+
+- Removed `Constrained Execution Region` error handling blocks and associated `SqlConnection` cleanup.
+  ([#3535](https://github.com/dotnet/SqlClient/pull/3535))
+
+- Performance improvements across SqlStatistics timing, Always Encrypted scenarios, and connection opening:
+  ([#3609](https://github.com/dotnet/SqlClient/pull/3609),
+   [#3612](https://github.com/dotnet/SqlClient/pull/3612),
+   [#3732](https://github.com/dotnet/SqlClient/pull/3732),
+   [#3660](https://github.com/dotnet/SqlClient/pull/3660),
+   [#3791](https://github.com/dotnet/SqlClient/pull/3791),
+   [#3772](https://github.com/dotnet/SqlClient/pull/3772),
+   [#3554](https://github.com/dotnet/SqlClient/pull/3554))
+
+- Allow `SqlBulkCopy` to operate on hidden columns.
+  ([#3590](https://github.com/dotnet/SqlClient/pull/3590))
+
+- Updated UserAgent feature to use a pipe-delimited format, replacing the previous JSON format.
+  ([#3826](https://github.com/dotnet/SqlClient/pull/3826))
+
+- Minor improvements to Managed SNI tracing to capture continuation events and errors.
+  ([#3859](https://github.com/dotnet/SqlClient/pull/3859))
+
+### Fixed
+
+- Fixed a connection performance regression where SPN generation was triggered for non-integrated authentication modes (e.g., SQL authentication) on the native SNI path.
+  ([#3929](https://github.com/dotnet/SqlClient/pull/3929))
+
+- Fixed `ExecuteScalar` to propagate errors when the server sends data followed by an error token.
+  ([#3912](https://github.com/dotnet/SqlClient/pull/3912))
+
+- Fixed `NullReferenceException` in `SqlDataAdapter` when processing batch scenarios.
+  ([#3857](https://github.com/dotnet/SqlClient/pull/3857))
+
+- Fixed reading of multiple app context switches from a single `AppContextSwitchOverrides` configuration field.
+  ([#3960](https://github.com/dotnet/SqlClient/pull/3960))
+
+- Fixed an edge case in `TdsParserStateObject.TryReadPlpBytes` where zero-length reads returned `null` instead of an empty array.
+  ([#3872](https://github.com/dotnet/SqlClient/pull/3872))
+
+- Fixed issue where extra connection deactivation was occurring.
+  ([#3758](https://github.com/dotnet/SqlClient/pull/3758))
+
+- Fixed debug assertion in connection pool (no impact to production code).
+  ([#3587](https://github.com/dotnet/SqlClient/pull/3587))
+
+- Prevented uninitialized performance counters escaping `CreatePerformanceCounters`.
+  ([#3623](https://github.com/dotnet/SqlClient/pull/3623))
+
+- Fixed `SetProvider` to return immediately if user-defined authentication provider found.
+  ([#3620](https://github.com/dotnet/SqlClient/pull/3620))
+
+- Fixed connection pool concurrency issue.
+  ([#3632](https://github.com/dotnet/SqlClient/pull/3632))

+# Release Notes
+
+## Stable Release 7.0.1 - 2026-04-23
+
+This update brings the following changes since the [7.0.0](7.0.0.md) release:
+
+### Fixed
+
+- Fixed `SqlBulkCopy` failing on SQL Server 2016 with `Invalid column name 'graph_type'` error. The column metadata query now uses dynamic SQL so that references to the `graph_type` column (introduced in SQL Server 2017) are not compiled on older versions that lack the column.
+  ([#3714](https://github.com/dotnet/SqlClient/issues/3714),
+   [#4092](https://github.com/dotnet/SqlClient/pull/4092),
+   [#4147](https://github.com/dotnet/SqlClient/pull/4147))
+
+- Fixed `SqlBulkCopy` failing on Azure Synapse Analytics dedicated SQL pools. The column-list query previously used a variable-assignment pattern that Synapse does not support; it now uses `STRING_AGG` when targeting Synapse (engine edition 6) and falls back to the variable-assignment approach for SQL Server 2016 compatibility.
+  ([#4149](https://github.com/dotnet/SqlClient/issues/4149),
+   [#4176](https://github.com/dotnet/SqlClient/pull/4176),
+   [#4182](https://github.com/dotnet/SqlClient/pull/4182))
+
+- Fixed `SqlDataReader.GetFieldType()` and `GetProviderSpecificFieldType()` returning `typeof(byte[])` instead of `typeof(SqlVector<float>)` for vector float32 columns. The methods now follow the same type-determination logic as `GetValue()`.
+  ([#4104](https://github.com/dotnet/SqlClient/issues/4104),
+   [#4105](https://github.com/dotnet/SqlClient/pull/4105),
+   [#4152](https://github.com/dotnet/SqlClient/pull/4152))
+
+- Added missing `System.Data.Common` (v4.3.0) NuGet package dependency for .NET Framework consumers. The inbox `System.Data.Common` assembly on .NET Framework predates APIs such as `IDbColumnSchemaGenerator`; without the explicit NuGet dependency, consumers encountered `CS0012` compilation errors when using these types through `Microsoft.Data.SqlClient`.
+  ([#4063](https://github.com/dotnet/SqlClient/pull/4063),
+   [#4074](https://github.com/dotnet/SqlClient/pull/4074))
+
+### Changed
+
+- Enabled the User Agent TDS feature extension unconditionally. The `Switch.Microsoft.Data.SqlClient.EnableUserAgent` AppContext switch has been removed; the driver now always sends User Agent information during login.
+  ([#4124](https://github.com/dotnet/SqlClient/pull/4124),
+   [#4154](https://github.com/dotnet/SqlClient/pull/4154))
+
+- Added type forwards from the core `Microsoft.Data.SqlClient` assembly to public types that were moved to the `Microsoft.Data.SqlClient.Extensions.Abstractions` package: `SqlAuthenticationMethod`, `SqlAuthenticationParameters`, `SqlAuthenticationProvider`, `SqlAuthenticationProviderException`, and `SqlAuthenticationToken`. This ensures binary compatibility for assemblies compiled against earlier versions of `Microsoft.Data.SqlClient` where these types lived in the core assembly.
+  ([#4067](https://github.com/dotnet/SqlClient/pull/4067),
+   [#4117](https://github.com/dotnet/SqlClient/pull/4117))
+
+- Fixed API documentation include paths and duplicate doc snippets.
+  ([#4084](https://github.com/dotnet/SqlClient/pull/4084),
+   [#4086](https://github.com/dotnet/SqlClient/pull/4086),
+   [#4107](https://github.com/dotnet/SqlClient/pull/4107),
+   [#4161](https://github.com/dotnet/SqlClient/pull/4161))

+# Release Notes
+
+## Stable Release 7.0.2 - 2026-06-24
+
+This update brings the following changes since the [7.0.1](7.0.1.md) release:
+
+> **Important — package version alignment:** Starting with 7.0.2, the `Microsoft.Data.SqlClient` driver and its companion packages share a single aligned version. The following packages now ship together as `7.0.2`:
+>
+> - `Microsoft.Data.SqlClient`
+> - `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`
+> - `Microsoft.Data.SqlClient.Extensions.Azure`
+> - `Microsoft.Data.SqlClient.Extensions.Abstractions`
+> - `Microsoft.Data.SqlClient.Internal.Logging`
+>
+> (`Microsoft.SqlServer.Server` continues to version independently and remains at `1.0.0`.)
+>
+> Applications must reference the same versions of `Microsoft.Data.SqlClient` and its extensions for best compatibility. In particular, applications that reference `Microsoft.Data.SqlClient.Extensions.Azure` must upgrade it to `7.0.2` when upgrading `Microsoft.Data.SqlClient` to `7.0.2`.
+
+> **Breaking change (.NET Framework only):** As part of this alignment, the `AssemblyVersion` of `Microsoft.Data.SqlClient.Extensions.Azure`, `Microsoft.Data.SqlClient.Extensions.Abstractions`, and `Microsoft.Data.SqlClient.Internal.Logging` changed from `1.0.0.0` to `7.0.0.0` (the `Microsoft.Data.SqlClient` and `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider` assembly versions are unchanged). On .NET Framework, `AssemblyVersion` is part of the strong-name identity, so applications that drop these assemblies into an existing deployment without rebuilding must rebuild against the 7.0.2 packages (or add binding redirects). Applications on .NET / .NET Core are not affected.
+
+### Companion package release notes
+
+The following companion packages ship aligned as `7.0.2`. See their individual release notes for package-specific changes (including the `Microsoft.Data.SqlClient.Extensions.Azure` WAM broker support):
+
+- [Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider 7.0.2](../add-ons/AzureKeyVaultProvider/7.0/7.0.2.md)
+- [Microsoft.Data.SqlClient.Extensions.Azure 7.0.2](../Extensions/Azure/7.0/7.0.2.md)
+- [Microsoft.Data.SqlClient.Extensions.Abstractions 7.0.2](../Extensions/Abstractions/7.0/7.0.2.md)
+- [Microsoft.Data.SqlClient.Internal.Logging 7.0.2](../Internal/Logging/7.0/7.0.2.md)
+
+### Fixed
+
+- Fixed a `NullReferenceException` in `SqlCommand.Cancel()`. The diagnostic message built during cancellation dereferenced the active connection directly; it now uses a null-conditional access so cancellation no longer throws when the connection has already been torn down.
+  ([#4372](https://github.com/dotnet/SqlClient/pull/4372),
+   [#4373](https://github.com/dotnet/SqlClient/pull/4373))
+
+- Fixed a `NullReferenceException` in `SqlDataReader` when calling `GetBytes`/`GetChars` with a `null` destination buffer. The argument-validation path that constructs the `InvalidDestinationBufferIndex` exception now guards against the null buffer so the correct `ArgumentException` is surfaced instead of an NRE.
+  ([#4159](https://github.com/dotnet/SqlClient/pull/4159),
+   [#4206](https://github.com/dotnet/SqlClient/pull/4206))
+
+- Fixed Always Encrypted column master key signature verification incorrectly reusing cached results. The `SignatureVerificationCache` lookup logic was corrected so signature verification outcomes are cached and retrieved against the correct key, preventing stale or mismatched verification results.
+  ([#4339](https://github.com/dotnet/SqlClient/pull/4339),
+   [#4343](https://github.com/dotnet/SqlClient/pull/4343))
+
+### Changed
+
+#### Hardened TDS token parsing with data-length bounds checks
+
+*What Changed:*
+
+- Added bounds checking when parsing TDS token and feature-extension-acknowledgment data lengths. The parser now validates the declared length of incoming token data against the available buffer before reading, rejecting malformed or out-of-range length values instead of reading past the intended boundary.
+  ([#4340](https://github.com/dotnet/SqlClient/pull/4340),
+   [#4358](https://github.com/dotnet/SqlClient/pull/4358))
+
+*Who Benefits:*
+
+- All consumers benefit from improved resilience against malformed or hostile TDS responses. A server (or man-in-the-middle) sending an invalid token length can no longer drive the parser to read beyond the declared payload.
+
+*Impact:*
+
+- Connections that previously parsed malformed token streams loosely will now fail fast with a clear protocol error. Well-behaved SQL Server responses are unaffected.

+# Release Notes
+
+## Stable Release 7.0.3 - 2026-09-10
+
+This update brings the following changes since the [7.0.2](7.0.2.md) release:
+
+The core driver and its companion packages ship together as version `7.0.3`. Update the companion packages you use alongside the driver to `7.0.3`. Assembly versions remain `7.0.0.0`, unchanged from `7.0.2`.
+
+### Companion package release notes
+
+- [Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider 7.0.3](../add-ons/AzureKeyVaultProvider/7.0/7.0.3.md)
+- [Microsoft.Data.SqlClient.Extensions.Azure 7.0.3](../Extensions/Azure/7.0/7.0.3.md) — includes the Entra ID authority parsing fix for Dataverse/Dynamics 365 connections.
+- [Microsoft.Data.SqlClient.Extensions.Abstractions 7.0.3](../Extensions/Abstractions/7.0/7.0.3.md)
+- [Microsoft.Data.SqlClient.Internal.Logging 7.0.3](../Internal/Logging/7.0/7.0.3.md)
+
+### Changed
+
+- Updated the `Microsoft.Data.SqlClient.SNI` and `Microsoft.Data.SqlClient.SNI.runtime` dependencies to 6.0.3 (was 6.0.2).
+  ([#4599](https://github.com/dotnet/SqlClient/pull/4599))
+
+### Fixed
+
+- Fixed a `SqlBulkCopy` regression in environments where the application login cannot read `sys.all_columns`. Bulk copy now falls back to the earlier column-discovery behavior when that permission is unavailable. Support for hidden columns and SQL Graph column aliases still requires access to the metadata view.
+  ([#4370](https://github.com/dotnet/SqlClient/issues/4370), [#4306](https://github.com/dotnet/SqlClient/pull/4306), [#4402](https://github.com/dotnet/SqlClient/pull/4402))
+
+- Fixed a memory-allocation regression in connection and command operations caused by formatting diagnostic strings even when tracing was disabled. Also corrected trace messages that reported an incorrect object ID or could throw `FormatException` when traced values contained braces.
+  ([#4528](https://github.com/dotnet/SqlClient/pull/4528), [#4533](https://github.com/dotnet/SqlClient/pull/4533))
+
+- Fixed `ServerCertificate` validation on the managed SNI path so the configured certificate is compared against the server certificate even when the server certificate passes chain and host-name validation. When certificate validation is enabled, a missing, unreadable, or invalid certificate file, a certificate mismatch, or a missing server certificate now causes the TLS handshake to fail instead of bypassing the configured certificate check. (net8.0/net9.0 only)
+  ([#4445](https://github.com/dotnet/SqlClient/pull/4445), [#4583](https://github.com/dotnet/SqlClient/pull/4583))
+
+- Fixed Always Encrypted VSM/HGS enclave attestation to verify that the enclave public key used to establish a session matches the key committed to by the signed attestation report. Missing, malformed, or mismatched key-binding data now causes attestation to fail before the session secret is derived.
+  ([#4532](https://github.com/dotnet/SqlClient/pull/4532), [#4553](https://github.com/dotnet/SqlClient/pull/4553))
+
+- Fixed `SqlConnection.AccessTokenCallback` not disabling Transparent Network IP Resolution by default, making it consistent with `SqlConnection.AccessToken`. An explicitly configured `TransparentNetworkIPResolution` connection-string value still takes precedence. (net462 only)
+  ([#4520](https://github.com/dotnet/SqlClient/pull/4520), [#4561](https://github.com/dotnet/SqlClient/pull/4561))
+
+- Fixed authentication state handling so clearing `SqlConnection.AccessToken`, `AccessTokenCallback`, or `SspiContextProvider` preserves the other authentication values in the connection pool key. Cloning a connection or updating its credential also preserves its `SspiContextProvider`. Combining a non-null `SspiContextProvider` with `AccessToken` or `AccessTokenCallback` now throws `InvalidOperationException` instead of silently discarding authentication state; applications must use one authentication mechanism at a time.
+  ([#4520](https://github.com/dotnet/SqlClient/pull/4520), [#4561](https://github.com/dotnet/SqlClient/pull/4561), [#4644](https://github.com/dotnet/SqlClient/pull/4644))
+
+- Fixed configurable retry logic installing a permanent, process-wide assembly-resolution handler that could interfere with unrelated assembly loading. The handler is now active only while an explicitly configured custom retry provider is resolved and constructed, and probes `AppContext.BaseDirectory` instead of the current working directory. Place custom retry assemblies in the application base directory; dependencies loaded after provider construction must be resolvable through normal application dependency resolution or an application-provided handler. (net8.0/net9.0 only)
+  ([#2214](https://github.com/dotnet/SqlClient/issues/2214), [#4547](https://github.com/dotnet/SqlClient/pull/4547), [#4663](https://github.com/dotnet/SqlClient/pull/4663))

+# Release Notes
+
+## Preview Release 7.1.0-preview1 - 2026-04-29
+
+This update brings the following changes since the [7.0.0](../7.0/7.0.0.md) release:
+
+### Added
+
+#### `SqlBatch` Support on .NET Framework
+
+*What Changed:*
+
+- Added `SqlBatch` and related batch-command support for the .NET Framework target so the batching API is now available across the full supported platform matrix, including `net462`.
+  ([#3926](https://github.com/dotnet/SqlClient/pull/3926))
+
+*Who Benefits:*
+
+- Applications that target .NET Framework but also want to use the newer batching APIs no longer need a separate implementation strategy from .NET 8/9 applications.
+- Libraries that multi-target .NET Framework and modern .NET can use a more consistent data-access surface area.
+
+*Impact:*
+
+- `SqlBatch`, `SqlBatchCommand`, and the related execution methods are now usable on .NET Framework builds in addition to .NET.
+
+#### Cross-Driver Connection-String Synonym Alignment
+
+*What Changed:*
+
+- Added additional accepted connection-string synonyms for better compatibility with other SQL Server drivers and existing connection-string conventions. Newly accepted synonyms include `ColumnEncryption`, `ConnectTimeout`, `FailoverPartner`, `PacketSize`, and `WorkstationId`.
+  ([#4192](https://github.com/dotnet/SqlClient/pull/4192))
+
+*Who Benefits:*
+
+- Applications migrating connection strings from other SQL Server drivers or shared infrastructure can reuse more existing keywords without rewriting them first.
+
+*Impact:*
+
+- Existing canonical keywords continue to work unchanged; this preview simply accepts more equivalent aliases during parsing.
+
+### Changed
+
+#### Connection Pool Clearing Now Works With Pool v2 (Experimental)
+
+*What Changed:*
+
+- Implemented the channel-based pool clear path so `SqlConnection.ClearPool(SqlConnection)` and `SqlConnection.ClearAllPools()` now work correctly when the newer pool v2 implementation is active.
+  ([#4194](https://github.com/dotnet/SqlClient/pull/4194))
+
+*Who Benefits:*
+
+- Applications that rely on pool clearing after failover, credential rotation, or server-side configuration changes now get the same semantics regardless of which internal pool implementation is active.
+
+*Impact:*
+
+- Idle pooled connections are closed immediately during a clear operation, while in-use connections are invalidated and discarded when returned to the pool.
+
+*Please Note:* Connection Pooling v2 is still experiemental.
+
+#### Type Forwards for Authentication Abstractions
+
+*What Changed:*
+
+- Added type forwards from the core `Microsoft.Data.SqlClient` assembly to public authentication-related types that were moved into `Microsoft.Data.SqlClient.Extensions.Abstractions`, including `SqlAuthenticationMethod`, `SqlAuthenticationParameters`, `SqlAuthenticationProvider`, `SqlAuthenticationProviderException`, and `SqlAuthenticationToken`.
+  ([#4067](https://github.com/dotnet/SqlClient/pull/4067),
+   [#4117](https://github.com/dotnet/SqlClient/pull/4117))
+
+*Who Benefits:*
+
+- Applications and libraries compiled against earlier package layouts retain binary compatibility when those authentication types are resolved from the core assembly name.
+
+*Impact:*
+
+- No application code changes are required; the type forwards preserve existing compiled references.
+
+#### User Agent Feature Extension Enabled by Default
+
+*What Changed:*
+
+- Enabled the User Agent TDS feature extension by default and removed the opt-in requirement to toggle it through `Switch.Microsoft.Data.SqlClient.EnableUserAgent`.
+  ([#4124](https://github.com/dotnet/SqlClient/pull/4124),
+   [#4154](https://github.com/dotnet/SqlClient/pull/4154))
+
+*Who Benefits:*
+
+- Operators and diagnostic tooling gain more consistent client-identification metadata during connection establishment without extra application configuration.
+
+*Impact:*
+
+- User-agent metadata is now always sent during login. Applications that previously enabled the switch explicitly can remove that configuration with no functional loss.
+
+#### Other changes
+
+- Reduced allocations when sending large string values to SQL Server.
+  ([#4072](https://github.com/dotnet/SqlClient/pull/4072))
+
+- Internal source-build and packaging consolidation updates:
+  ([#4033](https://github.com/dotnet/SqlClient/pull/4033),
+   [#4068](https://github.com/dotnet/SqlClient/pull/4068),
+   [#4204](https://github.com/dotnet/SqlClient/pull/4204))
+
+### Fixed
+
+- Fixed `SqlBulkCopy` failing on SQL Server 2016 with `Invalid column name 'graph_type'` by extracting graph-column metadata with dynamic SQL instead of referencing the column directly.
+  ([#3714](https://github.com/dotnet/SqlClient/issues/3714),
+   [#4092](https://github.com/dotnet/SqlClient/pull/4092),
+   [#4147](https://github.com/dotnet/SqlClient/pull/4147))
+
+- Fixed `SqlBulkCopy` support for Azure Synapse Analytics dedicated SQL pools by using a Synapse-compatible column-list query path.
+  ([#4149](https://github.com/dotnet/SqlClient/issues/4149),
+   [#4176](https://github.com/dotnet/SqlClient/pull/4176),
+   [#4182](https://github.com/dotnet/SqlClient/pull/4182))
+
+- Fixed `SqlDataReader.GetFieldType()` and `GetProviderSpecificFieldType()` to return `SqlVector<float>` metadata for vector float32 columns instead of `byte[]`.
+  ([#4104](https://github.com/dotnet/SqlClient/issues/4104),
+   [#4105](https://github.com/dotnet/SqlClient/pull/4105),
+   [#4152](https://github.com/dotnet/SqlClient/pull/4152))
+
+- Added the missing `System.Data.Common` NuGet dependency for .NET Framework consumers to avoid `CS0012` compile failures against newer ADO.NET surface area.
+  ([#4063](https://github.com/dotnet/SqlClient/pull/4063),
+   [#4074](https://github.com/dotnet/SqlClient/pull/4074))
+
+- Fixed a `SqlDataReader` streaming bug where calling `IsDBNull()` before reading a streamed value could skip column data.
+  ([#4082](https://github.com/dotnet/SqlClient/pull/4082))
+
+- Fixed a `NullReferenceException` in `SqlDataReader` during specific reader state transitions.
+  ([#4159](https://github.com/dotnet/SqlClient/pull/4159))
+
+## Target Platform Support

+# Release Notes
+
+## Preview Release 7.1.0-preview2 - 2026-07-09
+
+This update brings the following changes since the [7.1.0-preview1](7.1.0-preview1.md) release:
+
+> **Important — package version alignment:** Starting with the [7.0.2](../7.0/7.0.2.md) release, the `Microsoft.Data.SqlClient` driver and its companion packages share a single aligned version. Preview 2 of the `7.1` line continues this alignment; the following packages ship together as `7.1.0-preview2`:
+>
+> - `Microsoft.Data.SqlClient`
+> - `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`
+> - `Microsoft.Data.SqlClient.Extensions.Azure`
+> - `Microsoft.Data.SqlClient.Extensions.Abstractions`
+> - `Microsoft.Data.SqlClient.Internal.Logging`
+>
+> (`Microsoft.SqlServer.Server` continues to version independently and remains at `1.0.0`.)
+>
+> Applications must reference the same versions of `Microsoft.Data.SqlClient` and its extensions for best compatibility. In particular, applications that reference `Microsoft.Data.SqlClient.Extensions.Azure` must upgrade it to `7.1.0-preview2` when upgrading `Microsoft.Data.SqlClient` to `7.1.0-preview2`.
+>
+> **Compatibility guarantee:** All aligned assemblies ship with `FileVersion 7.1.0.x` and `AssemblyVersion 7.0.0.0`. The `AssemblyVersion` is unchanged from [7.0.2](../7.0/7.0.2.md), so upgrading from `7.0.2` to `7.1.0-preview2` does **not** require any new .NET Framework strong-name binding redirects. See the 7.0.2 release notes for the original `AssemblyVersion` alignment (the one-time breaking change that raised `AssemblyVersion` from `1.0.0.0` to `7.0.0.0` for `Extensions.Azure`, `Extensions.Abstractions`, and `Internal.Logging`; `AzureKeyVaultProvider` was already on `7.x`).
+
+### Added
+
+#### `SqlConnection.GetSchemaAsync`
+
+*What Changed:*
+
+- Added asynchronous overloads of `SqlConnection.GetSchema` that mirror the existing synchronous shapes and honor a supplied `CancellationToken`. The .NET Framework schema code paths were also unified with the .NET Core implementation.
+  ([#3005](https://github.com/dotnet/SqlClient/pull/3005))
+
+*Who Benefits:*
+
+- Applications that enumerate database metadata (databases, tables, columns, procedures, etc.) as part of a request pipeline can now do so without blocking a thread on synchronous I/O.
+
+*Impact:*
+
+- New `GetSchemaAsync(...)` overloads are additive; existing `GetSchema(...)` calls are unchanged.
+
+#### SQL Graph Column Aliases in `SqlBulkCopy`
+
+*What Changed:*
+
+- `SqlBulkCopy` column mappings now accept the SQL Graph pseudo-column aliases `$node_id`, `$edge_id`, `$from_id`, and `$to_id` as destination column names and transparently map them to the underlying physical columns.
+  ([#3677](https://github.com/dotnet/SqlClient/pull/3677))
+
+*Who Benefits:*
+
+- Applications that bulk-load SQL Graph node or edge tables can now map source fields directly to the friendly graph aliases instead of pre-computing the internal physical column names.
+
+*Impact:*
+
+- Existing mappings continue to work; if a physical column with the same name as an alias already exists, the physical column keeps priority.
+
+#### `SqlBatchCommand.CommandBehavior` Is Now Honored
+
+*What Changed:*
+
+- The `SqlBatchCommand.CommandBehavior` property (which existed since batching was introduced but was previously ignored) is now plumbed through the batch execution path so per-command behaviors are honored inside a `SqlBatch`. `SqlBatch.ExecuteReader` also now respects the `CommandBehavior` value passed to it.
+  ([#4125](https://github.com/dotnet/SqlClient/pull/4125))
+
+*Who Benefits:*
+
+- Applications composing heterogeneous batches (for example, mixing `SchemaOnly` metadata queries with data-returning statements) can now express per-command reader behavior without splitting the batch.
+
+*Impact:*
+
+- Batches that previously set `SqlBatchCommand.CommandBehavior` but relied on it being ignored will now see that value applied. Batches that left it at the default (`CommandBehavior.Default`) are unaffected.
+
+#### Configurable Idle Connection Timeout
+
+*What Changed:*
+
+- Added a `Connection Idle Timeout` connection-string keyword and matching `SqlConnectionStringBuilder.IdleTimeout` property that let the connection pool evict pooled connections whose idle time exceeds the configured value. The default is `300` seconds; setting `0` disables idle expiration, and negative values throw `ArgumentException`. Enforcement is gated on the new `Switch.Microsoft.Data.SqlClient.UseLegacyIdleTimeoutBehavior` AppContext switch, which defaults to `true` to preserve historical pooling behavior; set it to `false` to enable idle-timeout enforcement.
+  ([#4295](https://github.com/dotnet/SqlClient/pull/4295))
+
+*Who Benefits:*
+
+- Applications running against Azure SQL Database and other elastic backends can bound connection idle time to align with server-side session recycling and reduce stale-connection failures.
+
+*Impact:*
+
+- Default behavior is unchanged: the new keyword is parsed but not enforced until the legacy switch is turned off. When enabled, idle-timeout enforcement applies to the existing connection pool as well.
+
+### Changed
+
+#### Connection Timeout Now Propagates Through the Pool
+
+*What Changed:*
+
+- Replaced raw `TimeSpan` timeouts with a shared `TimeoutTimer` across `SqlConnection.Open[Async]`, pool acquisition, and physical connection creation, so the `Connect Timeout` budget can be deducted as a request waits in the pool. Introduces a dependency on `Microsoft.Bcl.TimeProvider`. Enforcement is gated on the new `Switch.Microsoft.Data.SqlClient.UseOverallConnectTimeoutForPoolWait` AppContext switch, which defaults to `false` to preserve historical behavior; set it to `true` to have pool waits count against the caller's `Connect Timeout` budget.
+  ([#4270](https://github.com/dotnet/SqlClient/pull/4270))
+
+*Who Benefits:*
+
+- Applications that observe pool contention can opt in via the new switch to have the configured `Connect Timeout` respected end-to-end instead of the budget effectively restarting when a physical connection is eventually opened.
+
+*Impact:*
+
+- Default behavior is unchanged: pool waits do not count against `Connect Timeout` unless the new switch is enabled. When enabled, `Open`/`OpenAsync` under heavy pool contention may surface timeouts sooner than before. Successful opens are unaffected.
+
+#### Other changes
+
+- Added the SQL Server 2025 `json` data type to the `DataTypes` collection returned by `SqlConnection.GetSchema`. ([#3858](https://github.com/dotnet/SqlClient/pull/3858))
+- Refactored `SqlConnection` internal state transitions to use `Interlocked.CompareExchange` guards, hardening the driver against races surfaced by concurrent open/close/reconnect. ([#4267](https://github.com/dotnet/SqlClient/pull/4267))
+- Removed legacy connection-options inheritance from internal APIs, simplifying `TryOpenConnection`, `TryReplaceConnection`, and the pool interfaces. ([#4237](https://github.com/dotnet/SqlClient/pull/4237), [#4261](https://github.com/dotnet/SqlClient/pull/4261), [#4235](https://github.com/dotnet/SqlClient/pull/4235))
+- Refactored `ForceNewConnection` handling. ([#4415](https://github.com/dotnet/SqlClient/pull/4415))
+- Added Async generic helpers to reduce duplication across sync/async code paths. ([#4334](https://github.com/dotnet/SqlClient/pull/4334))
+- Use hardcoded LCID mappings when decoding strings, avoiding repeated culture lookups. ([#4212](https://github.com/dotnet/SqlClient/pull/4212))
+- Reduced allocations by avoiding lock acquisition on `SqlErrorCollection` counters when no errors exist, and by avoiding stack-trace materialization for expected `null`-return paths. ([#4157](https://github.com/dotnet/SqlClient/pull/4157), [#4099](https://github.com/dotnet/SqlClient/pull/4099), [#4102](https://github.com/dotnet/SqlClient/pull/4102))
+- Improved `EnclaveDiffieHellmanInfo.Size` accuracy. ([#4346](https://github.com/dotnet/SqlClient/pull/4346))
+- `SqlVector<float>` now serializes and deserializes little-endian multibyte values explicitly for consistent behavior across architectures. ([#3861](https://github.com/dotnet/SqlClient/pull/3861))
+- Updated the bundled .NET 10 SDK to `10.0.300`. ([#4287](https://github.com/dotnet/SqlClient/pull/4287))
+
+### Fixed
+
+- Fixed a `NullReferenceException` in `SqlCommand.Cancel()` when the active connection has already been torn down. ([#4372](https://github.com/dotnet/SqlClient/pull/4372))
+- Fixed Always Encrypted column master key signature verification incorrectly reusing cached results after a prior verification failure. ([#4339](https://github.com/dotnet/SqlClient/pull/4339))
+- Fixed missing bounds checks on TDS token and feature-extension-acknowledgment data lengths that could allow a spoofing server to trigger unbounded allocations. ([#4340](https://github.com/dotnet/SqlClient/pull/4340))
+- Fixed `SqlBulkCopy` failing in least-privilege environments where the caller lacks permission to run the previous metadata query path. ([#4306](https://github.com/dotnet/SqlClient/pull/4306))
+- Fixed Always Encrypted reads of `CekMdVersion` and `EkValueCount` to align with the TDS specification. ([#4240](https://github.com/dotnet/SqlClient/pull/4240))
+- Fixed `LoginWithFailover` to validate parser state before continuing, preventing null-reference failures during failover login. ([#4140](https://github.com/dotnet/SqlClient/pull/4140))
+- Fixed the SPN used during login to use the resolved port instead of the instance name when `Protocol=None` or `Protocol=Admin` is specified. ([#4180](https://github.com/dotnet/SqlClient/pull/4180))
+- Fixed a race in `SqlConnection.TryOpenInner` that could surface as `InvalidCastException`; the same race now returns a deterministic `InvalidOperationException`. ([#4179](https://github.com/dotnet/SqlClient/pull/4179))
+- Fixed several `CancellationTokenSource` leaks in `SqlDataReader`, `SqlConnection`, `SqlCommand` reconnect paths, and the sequential-stream helpers. ([#4009](https://github.com/dotnet/SqlClient/pull/4009))
+- Documentation fix for server certificate configuration. ([#4408](https://github.com/dotnet/SqlClient/pull/4408))
+
+### Removed
+
+#### SQL Server 7.0 and 2000 Support
+
+*What Changed:*
+
+- Removed dead protocol-level code paths for SQL Server 7.0 and SQL Server 2000, along with the now-orphaned `SQL Server 2000` type-system compatibility option. The `TypeSystem.SQLServer2000` enum value and the `Type System Version=SQL Server 2000` connection-string branch are gone.
+  ([#4015](https://github.com/dotnet/SqlClient/pull/4015))
+
+*Who Benefits:*
+
+- The driver no longer carries dead legacy code, and the documented connection-string surface (`Latest`, `SQL Server 2005`, `SQL Server 2008`, `SQL Server 2012`) now matches the implementation exactly.
+
+*Impact:*
+
+- **Breaking:** A connection string that specifies `Type System Version=SQL Server 2000` now throws `ArgumentException` when the connection is opened, instead of being accepted. Applications currently using this value should switch to a supported value such as `Latest`. There is no change to which servers the driver will connect to — SQL Server 7.0 and 2000 were already rejected during login version negotiation.

+# Release Notes
+
+## Preview Release 7.1.0-preview3 - 2026-08-26
+
+This update brings the following changes since the [7.1.0-preview2](7.1.0-preview2.md) release:
+
+> **Important — package version alignment:** Starting with the [7.0.2](../7.0/7.0.2.md) release, the `Microsoft.Data.SqlClient` driver and its companion packages share a single aligned version. Preview 3 of the `7.1` line continues this alignment; the following packages ship together as `7.1.0-preview3`:
+>
+> - `Microsoft.Data.SqlClient`
+> - `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`
+> - `Microsoft.Data.SqlClient.Extensions.Azure`
+> - `Microsoft.Data.SqlClient.Extensions.Abstractions`
+> - `Microsoft.Data.SqlClient.Internal.Logging`
+>
+> (`Microsoft.SqlServer.Server` continues to version independently and remains at `1.0.0`.)
+>
+> Applications must reference the same versions of `Microsoft.Data.SqlClient` and its extensions for best compatibility. In particular, applications that reference `Microsoft.Data.SqlClient.Extensions.Azure` must upgrade it to `7.1.0-preview3` when upgrading `Microsoft.Data.SqlClient` to `7.1.0-preview3`.
+>
+> **Compatibility guarantee:** All aligned assemblies ship with `FileVersion 7.1.0.x` and `AssemblyVersion 7.0.0.0`. The `AssemblyVersion` is unchanged from [7.0.2](../7.0/7.0.2.md), so upgrading from `7.0.2` to `7.1.0-preview3` does **not** require any new .NET Framework strong-name binding redirects.
+
+### Added
+
+#### Asynchronous Key Store Provider APIs for Always Encrypted
+
+*What Changed:*
+
+- Added four `virtual` asynchronous counterparts to the existing synchronous methods on the `SqlColumnEncryptionKeyStoreProvider` abstract base class: `DecryptColumnEncryptionKeyAsync`, `EncryptColumnEncryptionKeyAsync`, `SignColumnMasterKeyMetadataAsync`, and `VerifyColumnMasterKeyMetadataAsync`. Each takes an optional `CancellationToken`. The default implementations delegate to the existing synchronous methods, so providers that do not override them continue to work unchanged.
+  ([#3672](https://github.com/dotnet/SqlClient/issues/3672), [#3673](https://github.com/dotnet/SqlClient/pull/3673))
+
+*Who Benefits:*
+
+- Authors of custom column encryption key store providers — particularly those backed by network-bound key stores such as HSMs or cloud key vaults — can now implement genuinely asynchronous key operations, and callers that resolve column encryption keys directly through a provider can await them instead of blocking a thread on synchronous I/O.
+
+*Impact:*
+
+- Purely additive. Because the new methods are `virtual` with a synchronous fallback, existing providers compile and run without modification.
+- **Introduced, but not yet consumed by the driver.** These APIs are added to the public surface in this release so that provider authors can begin implementing them, but `Microsoft.Data.SqlClient` does not call them yet — the driver's own column encryption key resolution path (`SqlSecurityUtility`) still invokes the synchronous provider methods on both the synchronous and asynchronous command paths. Overriding the asynchronous methods therefore does not by itself remove blocking key-store I/O from `ExecuteReaderAsync` and friends. **A future release will enable their use from the driver's own asynchronous APIs.**
+- The in-box `SqlColumnEncryptionAzureKeyVaultProvider` overrides all four methods in this release. See the [AzureKeyVaultProvider 7.1.0-preview3](../add-ons/AzureKeyVaultProvider/7.1/7.1.0-preview3.md) release notes. ([#4540](https://github.com/dotnet/SqlClient/pull/4540))
+
+#### Connection Pool V2 Feature Completeness
+
+*What Changed:*
+
+- Substantially expanded `ChannelDbConnectionPool`, the opt-in pool implementation gated behind the `Switch.Microsoft.Data.SqlClient.UseConnectionPoolV2` AppContext switch, bringing it to parity with the default `WaitHandleDbConnectionPool`:
+  - **Transaction support** — implemented `PutObjectFromTransactedPool` and `TransactionEnded` (previously `NotImplementedException`), and reworked connection return to mirror the reference pool's deactivate-then-route behavior. ([#4487](https://github.com/dotnet/SqlClient/pull/4487))
+  - **Connection replacement** — implemented replacement of broken connections during command execution, with atomic slot replacement in `ConnectionPoolSlots`. ([#4429](https://github.com/dotnet/SqlClient/pull/4429))
+  - **Background warmup and replenishment** — the pool now pre-creates connections up to `Min Pool Size` on startup and replenishes automatically whenever it drops below the minimum. ([#4452](https://github.com/dotnet/SqlClient/pull/4452))
+  - **Idle pruning** — the pruning window is now derived from the `Connection Idle Timeout` value rather than a hard-coded interval. Defaults are unchanged. ([#4463](https://github.com/dotnet/SqlClient/pull/4463))
+  - **Connection-creation rate limiting** — an optional `ConcurrencyLimiter` can throttle new physical connection creation; when a permit is denied the caller waits for an existing connection instead of forcing another open. ([#4395](https://github.com/dotnet/SqlClient/pull/4395), [#4396](https://github.com/dotnet/SqlClient/pull/4396))
+  - **Leaked connection reclamation** — the pool now reclaims leaked connections (connections whose owning `SqlConnection` was garbage collected without being closed) both inline on the requesting thread and, while callers are waiting, from a demand-driven `PoolReclaimer` timer. The `number-of-reclaimed-connections` counter, which previously always read zero under pool V2, is now emitted. ([#4529](https://github.com/dotnet/SqlClient/pull/4529))
+  - **Metrics and tracing parity** — the pool now emits the same pooled/free connection and soft/hard connect/disconnect counters as the default pool, and traces at comparable fidelity. ([#4504](https://github.com/dotnet/SqlClient/pull/4504))
+
+*Who Benefits:*
+
+- Applications evaluating the V2 connection pool can now exercise transaction-enlisted workloads, broken-connection recovery, leaked-connection reclamation, and pool warmup, and can observe the pool through the existing performance counters and EventSource traces.
+
+*Impact:*
+
+- No change to default behavior. `ChannelDbConnectionPool` is used only when `Switch.Microsoft.Data.SqlClient.UseConnectionPoolV2` is enabled; the default pool remains `WaitHandleDbConnectionPool`.
+- This work also surfaced connection pool performance counter defects that affect the **default** pool, which are listed under *Fixed* below.
+
+### Changed
+
+- Windows-only native SNI types are now removed cleanly by the IL trimmer on Linux and macOS, and `LocalAppContextSwitches.UseManagedNetworking` is now substituted for a constant (an `ILLink.Substitutions.xml` naming defect previously prevented this). The driver now builds a single OS-agnostic assembly for all platforms; the structure and contents of the NuGet package are unchanged. ([#4207](https://github.com/dotnet/SqlClient/pull/4207), [#4239](https://github.com/dotnet/SqlClient/issues/4239), [#4465](https://github.com/dotnet/SqlClient/pull/4465), [#4474](https://github.com/dotnet/SqlClient/pull/4474))
+- Reduced managed allocations in the async read path by restoring reuse of `PacketData` linked-list nodes via a bounded free list on `StateSnapshot`, recovering an allocation regression against the 6.1.6 baseline. This applies to the default async read path and is not gated behind any AppContext switch; `SqlCommand/ExecuteReaderAsync` returns from +120.9% allocated against the 6.1.6 baseline to +0.1%. ([#4536](https://github.com/dotnet/SqlClient/pull/4536))
+- `SqlBulkCopy` no longer builds SQL Graph column alias mapping tables when the source and destination tables contain no graph pseudo-columns (`$edge_id`, `$to_id`, `$from_id`, `$node_id`), recovering a bulk copy performance regression introduced with graph column alias support in [#3677](https://github.com/dotnet/SqlClient/pull/3677). Graph table bulk copy behavior is unchanged. ([#4535](https://github.com/dotnet/SqlClient/pull/4535))
+- Operations no longer allocate a formatted trace string when `SqlClientEventSource` tracing is disabled, recovering a memory regression against the 6.1.6 baseline. Trace output with tracing enabled is unchanged. ([#4528](https://github.com/dotnet/SqlClient/pull/4528))
+- Updated centrally managed dependency versions for the `net9.0` target framework to `9.0.18`, and added `System.Threading.RateLimiting` to the packaged dependency metadata. Non-`net9.0` targets keep their existing `8.0.x` pins. ([#4507](https://github.com/dotnet/SqlClient/pull/4507))
+- Updated the `Microsoft.Data.SqlClient.SNI` and `Microsoft.Data.SqlClient.SNI.runtime` dependencies to `7.1.0-preview3.26226.3`. ([#4564](https://github.com/dotnet/SqlClient/pull/4564))
+
+### Fixed
+
+- Fixed Always Encrypted VSM/HGS enclave attestation not verifying that the enclave public key used to establish the session matches the key committed to by the signed attestation report. The provider now compares `SHA-256(enclave public key)` against the report's `EnclaveData` using a fixed-time comparison, and rejects attestation when the data is missing, malformed, or mismatched. ([#4532](https://github.com/dotnet/SqlClient/pull/4532))
+- Fixed a `SqlConnectionFactory` timer that woke the process every 30 seconds for the lifetime of the application even when no connection pools existed — including with `Pooling=False` and after `ClearAllPools()`. The pruning timer is now armed on demand and disarmed once there is nothing left to prune. A missing .NET Framework unload hook was also added. ([#1881](https://github.com/dotnet/SqlClient/issues/1881), [#4479](https://github.com/dotnet/SqlClient/pull/4479))
+- Fixed connection pool performance counter defects affecting the **default** pool as well as pool V2. `active-soft-connects` and `number-of-active-connections` could go negative after a failed connection activation, and `active-soft-connects`, `active-hard-connections`, and `number-of-pooled-connections` drifted upward permanently after a broken connection was replaced. Because these are gauges, an unmatched increment or decrement never recovered for the lifetime of the process. ([#4504](https://github.com/dotnet/SqlClient/pull/4504))
+- Fixed `OverflowException` when sending large `decimal` values (for example `decimal.MaxValue`) as a parameter with explicit `Precision` and `Scale`, which primarily affected Always Encrypted scenarios where both must always be set. ([#1655](https://github.com/dotnet/SqlClient/issues/1655), [#4443](https://github.com/dotnet/SqlClient/pull/4443))
+- Fixed a TDS stream error when passing a `DateOnly` value as a parameter with `SqlDbType.Variant`; the required `sql_variant` write paths were missing. (net8.0/net9.0 only) ([#3953](https://github.com/dotnet/SqlClient/issues/3953), [#4294](https://github.com/dotnet/SqlClient/pull/4294))
+- Fixed `DateOnly` values written to a `sql_variant` column of a table-valued parameter being sent as `datetime` instead of `date`. Besides being incorrect, this caused an overflow for `DateOnly` values that are valid for `date` but out of range for `datetime`. Reading continues to return `DateTime` instances by default, for backwards compatibility. (net8.0/net9.0 only — .NET Framework has no `DateOnly` type) ([#3934](https://github.com/dotnet/SqlClient/issues/3934), [#4439](https://github.com/dotnet/SqlClient/pull/4439))
+- Fixed the `ServerCertificate` connection-string keyword not being honored when the platform reported no TLS policy errors. The configured certificate is now always compared against the certificate presented by the server, matching the documented exact-match semantic. If the configured file cannot be loaded or parsed, the connection now fails closed with an `SSLCertificateAuthenticationException` naming the path, rather than silently falling back to host-name validation. A null server certificate now throws `AuthenticationException` instead of `NullReferenceException`. Connections that do not set `ServerCertificate`, and those whose configured certificate matches, are unaffected. ([#4445](https://github.com/dotnet/SqlClient/pull/4445))
+- Fixed `SqlConnection.AccessTokenCallback` not disabling Transparent Network IP Resolution by default, unlike `SqlConnection.AccessToken`. Also fixed a related defect in how the authentication setters build the connection pool key, and made `SspiContextProvider` mutually exclusive with token-based authentication. (net462 only for the TNIR behavior) ([#4520](https://github.com/dotnet/SqlClient/pull/4520))
+- Fixed several async entry points in `SqlBulkCopy`, `SqlDataReader.InvokeAsyncCall`, `SqlCommand.Reader`, and `SqlCommand.Xml` that captured fatal exceptions such as `OutOfMemoryException` into faulted `Task`s instead of letting them propagate. ([#4437](https://github.com/dotnet/SqlClient/pull/4437))
+- Fixed `Authentication=Active Directory Service Principal` (and the interactive, password, integrated, and device-code flows) failing against endpoints such as the Dataverse / Dynamics 365 TDS endpoint, which return a multi-segment Entra ID authority (`https://login.microsoftonline.com/{tenantId}/oauth2/authorize`) in the TDS `FEDAUTHINFO` token. The tenant id is now taken from the first path segment of the authority instead of the last. This fix ships in `Microsoft.Data.SqlClient.Extensions.Azure`; see its [7.1.0-preview3](../Extensions/Azure/7.1/7.1.0-preview3.md) release notes. ([#4496](https://github.com/dotnet/SqlClient/issues/4496), [#4521](https://github.com/dotnet/SqlClient/pull/4521))

+## Stable Release 7.0.2 - 2026-06-24
+
+This release version-aligns `Microsoft.Data.SqlClient.Extensions.Abstractions` with the core `Microsoft.Data.SqlClient` driver version (`7.0.2`). The previous release of this package was `1.0.0`.
+
+There are no functional or API changes in this release. See the core [Microsoft.Data.SqlClient 7.0.2](../../../7.0/7.0.2.md) release notes for the driver-family changes shipped alongside this version.
+
+> **Version alignment:** Starting with this release, this package's version tracks the core `Microsoft.Data.SqlClient` driver version.
+
+> **Breaking change (.NET Framework only):** As part of this alignment, the assembly's `AssemblyVersion` changed from `1.0.0.0` to `7.0.0.0`. On .NET Framework, `AssemblyVersion` is part of the strong-name identity, so applications that replace this assembly in an existing deployment without rebuilding must rebuild against `7.0.2` (or add a binding redirect). Applications on .NET / .NET Core are not affected.

+# Release Notes
+
+## Stable Release 1.0.0 - 2026-03-17
+
+This is the first stable release of `Microsoft.Data.SqlClient.Extensions.Azure`, providing Microsoft Entra ID (Azure Active Directory) authentication support for Microsoft.Data.SqlClient. This package was extracted from the core driver to address the [most requested feature](https://github.com/dotnet/SqlClient/issues/1108) — making the core package lighter by removing Azure dependencies.
+
+## Changes Since [1.0.0-preview1](1.0.0-preview1.md)
+
+### Changed
+
+- Renamed dependency from `Microsoft.Data.SqlClient.Extensions.Logging` to `Microsoft.Data.SqlClient.Internal.Logging`.
+  ([#4038](https://github.com/dotnet/SqlClient/pull/4038))
+
+- Updated Dependencies
+  ([#4045](https://github.com/dotnet/SqlClient/pull/4045)):
+  - Updated `Azure.Core` to v1.51.1
+  - Updated `Azure.Identity` to v1.18.0
+  - Updated `Microsoft.Identity.Client` to v4.83.0
+
+## Cumulative Changes (First Stable Release)
+
+This is the first stable release of this package. The following summarizes all changes across the preview cycle.
+
+### Added
+
+- Entra ID authentication provider (`ActiveDirectoryAuthenticationProvider`) supporting:
+  - `ActiveDirectoryInteractive`
+  - `ActiveDirectoryDefault`
+  - `ActiveDirectoryManagedIdentity`
+  - `ActiveDirectoryServicePrincipal`
+  - `ActiveDirectoryDeviceCodeFlow`
+  - `ActiveDirectoryWorkloadIdentity`
+  - `ActiveDirectoryPassword` (deprecated)
+  ([#3680](https://github.com/dotnet/SqlClient/pull/3680),

+# Release Notes
+
+## Stable Release 7.0.2 - 2026-06-24
+
+This update brings the following changes since the [1.0.0](../1.0/1.0.0.md) release of `Microsoft.Data.SqlClient.Extensions.Azure`.
+
+> **Version alignment:** Starting with this release, the package version is aligned with the core `Microsoft.Data.SqlClient` driver version (`7.0.2`). The previous release of this package was `1.0.0`.
+
+> **Breaking change (.NET Framework only):** As part of this alignment, the assembly's `AssemblyVersion` changed from `1.0.0.0` to `7.0.0.0`. On .NET Framework, `AssemblyVersion` is part of the strong-name identity, so applications that replace this assembly in an existing deployment without rebuilding must rebuild against `7.0.2` (or add a binding redirect). Applications on .NET / .NET Core are not affected.
+
+### Added
+
+#### WAM broker support for Entra ID authentication (Windows only)
+
+*What Changed:*
+
+- Added support for the [Web Account Manager (WAM)](https://learn.microsoft.com/entra/msal/dotnet/acquiring-tokens/desktop-mobile/wam) broker for Microsoft Entra ID authentication flows. A new `ActiveDirectoryAuthenticationProviderOptions` options bag and a corresponding `ActiveDirectoryAuthenticationProvider(ActiveDirectoryAuthenticationProviderOptions options)` constructor were introduced, exposing a `UseWamBroker` property (alongside `ApplicationClientId` and `DeviceCodeFlowCallback`).
+- Added a cross-platform `SetParentActivityOrWindowFunc(Func<object>?)` method so callers can supply the parent window/activity used for interactive authentication UI — a window handle on Windows (where it also integrates with the WAM broker), or an `Activity`/`UIViewController` on Android/iOS. This supersedes the .NET Framework-only `SetIWin32WindowFunc`.
+  ([#4288](https://github.com/dotnet/SqlClient/pull/4288),
+   [#4388](https://github.com/dotnet/SqlClient/pull/4388))
+
+*Who Benefits:*
+
+- Applications using `ActiveDirectoryInteractive` and other supported Entra ID authentication modes on Windows benefit from the WAM broker's improved security (tokens are brokered by the OS), single sign-on with the logged-in Windows account, and support for Conditional Access and Windows Hello.
+
+*Impact:*
+
+- Enable the WAM broker by setting `ActiveDirectoryAuthenticationProviderOptions.UseWamBroker` to `true` and passing the options to the new constructor. Consider enabling it when you want OS-brokered token security, single sign-on with the signed-in Windows account, or support for Conditional Access and Windows Hello.
+- `UseWamBroker` is a **Windows-only** setting and has no effect on non-Windows platforms, where interactive Entra ID flows always use the system browser.
+- Prefer the new options-bag constructor over the positional-argument overloads in new code.
+
+```c#
+var options = new ActiveDirectoryAuthenticationProviderOptions
+{
+    ApplicationClientId = "<your-app-client-id>",
+    UseWamBroker = true, // Windows only
+};
+var provider = new ActiveDirectoryAuthenticationProvider(options);
+SqlAuthenticationProvider.SetProvider(SqlAuthenticationMethod.ActiveDirectoryInteractive, provider);
+```
+
+- A new `AzureSqlConnector` sample demonstrating interactive Entra ID authentication with and without the WAM broker was added under [doc/apps/AzureSqlConnector](../../../../doc/apps/AzureSqlConnector/README.md).
+
+### Changed
+
+- Updated Dependencies
+  ([#4288](https://github.com/dotnet/SqlClient/pull/4288)):
+  - Added `Microsoft.Identity.Client.Broker` v4.84.2 (required for WAM broker support).
+  - Updated `Microsoft.Identity.Client` to v4.84.2.

+
+## Stable Release 7.0.3 - 2026-09-10
+
+This update brings the following changes since the [7.0.2](7.0.2.md) release of `Microsoft.Data.SqlClient.Extensions.Azure`.
+
+This package ships version-aligned with the core [Microsoft.Data.SqlClient 7.0.3](../../../7.0/7.0.3.md) driver. Its `AssemblyVersion` remains `7.0.0.0`, unchanged from `7.0.2`.
+
+### Fixed
+
+- Fixed Entra ID authentication failures when the server supplies an authority URL with an OAuth endpoint suffix, such as `https://login.microsoftonline.com/<tenant>/oauth2/authorize`. The provider now extracts the tenant from the first path segment and normalizes the authority used by Azure.Identity and MSAL, restoring authentication to Dataverse/Dynamics 365 TDS endpoints, including `Active Directory Service Principal` authentication. Malformed authority URLs now produce a clear authentication error. Bare tenant authority URLs used by Azure SQL and Fabric retain their existing behavior.

+- Windows users get single sign-on with the signed-in Windows account, Windows Hello, and Conditional Access support through the OS broker. Device Code Flow now uses its own token-lifetime timeout instead of inheriting `Connect Timeout`, fixing spurious `"The operation was canceled."` failures when the user takes longer than a few seconds to enter the device code.
+
+*Impact:*
+
+- WAM is enabled by default when the driver's built-in client id is used. With a custom client id, WAM is opt-in via `ActiveDirectoryAuthenticationProviderOptions.UseWamBroker` or the `useWamBroker` config attribute. Non-Windows platforms never invoke the broker.
+- Existing `ActiveDirectoryAuthenticationProvider` constructors remain source- and binary-compatible.
+- Adding WAM broker support materially increases the on-disk footprint of `Microsoft.Data.SqlClient.Extensions.Azure` because it pulls in the `Microsoft.Identity.Client.Broker` package and its native OS-broker components. See [#4410](https://github.com/dotnet/SqlClient/issues/4410) for tracking.
+
+```c#
+var options = new ActiveDirectoryAuthenticationProviderOptions
+{
+    ApplicationClientId = "<your-app-client-id>",
+    UseWamBroker = true, // Windows only
+};
+var provider = new ActiveDirectoryAuthenticationProvider(options);
+SqlAuthenticationProvider.SetProvider(SqlAuthenticationMethod.ActiveDirectoryInteractive, provider);
+```
+
+- A new `AzureSqlConnector` sample demonstrating interactive Entra ID authentication with and without the WAM broker is available under [doc/apps/AzureSqlConnector](../../../../doc/apps/AzureSqlConnector/README.md).
+
+### Changed
+
+- Updated Dependencies
+  ([#4288](https://github.com/dotnet/SqlClient/pull/4288)):
+  - Added `Microsoft.Identity.Client.Broker` v4.84.2 (required for WAM broker support).
+  - Updated `Microsoft.Identity.Client` to v4.84.2.

+# Release Notes
+
+## Preview Release 7.1.0-preview3 - 2026-08-26
+
+This release fixes Entra ID tenant parsing for multi-segment authorities, and continues version-alignment of `Microsoft.Data.SqlClient.Extensions.Azure` with the core `Microsoft.Data.SqlClient` driver version (`7.1.0-preview3`). The previous release of this package was [7.1.0-preview2](7.1.0-preview2.md). See the core [Microsoft.Data.SqlClient 7.1.0-preview3](../../../7.1/7.1.0-preview3.md) release notes for the driver-family changes shipped alongside this version.
+
+> **Version alignment:** This package's version continues to track the core `Microsoft.Data.SqlClient` driver version. See the [7.0.2 release notes](../../../7.0/7.0.2.md) for the initial alignment announcement. This assembly ships with `FileVersion 7.1.0.x`. The `AssemblyVersion 7.0.0.0` remains unchanged from the `7.0.2` release.
+
+### Fixed
+
+- Fixed Entra ID tenant parsing for multi-segment STSURL authorities. Endpoints such as the Dataverse / Dynamics 365 TDS endpoint return an OAuth v1 style authority (`https://login.microsoftonline.com/{tenantId}/oauth2/authorize`) in the TDS `FEDAUTHINFO` token. `ActiveDirectoryAuthenticationProvider.AcquireTokenAsync` split that authority at the **last** `/`, so the credential received the literal string `"authorize"` as its tenant id and connections failed with `ClientSecretCredential authentication failed`. The tenant is now taken from the **first** path segment, so trailing endpoint suffixes (`/oauth2/authorize`, `/oauth2/v2.0/token`, ...) are ignored, and the normalized authority is used for the MSAL-based interactive, password, integrated, and device-code flows as well. An unparseable authority now raises a clear `AuthenticationException` naming the offending value, and provider-raised authentication errors are no longer re-wrapped as "Unexpected error". Behavior is unchanged for the bare `https://login.microsoftonline.com/{tenantId}` authority sent by Azure SQL, Fabric, and Synapse. There are no public API changes.

+This release version-aligns `Microsoft.Data.SqlClient.Internal.Logging` with the core `Microsoft.Data.SqlClient` driver version (`7.0.2`). The previous release of this package was `1.0.0`.
+
+There are no functional or API changes in this release. See the core [Microsoft.Data.SqlClient 7.0.2](../../../7.0/7.0.2.md) release notes for the driver-family changes shipped alongside this version.
+
+> **Version alignment:** Starting with this release, this package's version tracks the core `Microsoft.Data.SqlClient` driver version.
+
+> **Breaking change (.NET Framework only):** As part of this alignment, the assembly's `AssemblyVersion` changed from `1.0.0.0` to `7.0.0.0`. On .NET Framework, `AssemblyVersion` is part of the strong-name identity, so applications that replace this assembly in an existing deployment without rebuilding must rebuild against `7.0.2` (or add a binding redirect). Applications on .NET / .NET Core are not affected.

+
+> **Version alignment:** This package's version continues to track the core `Microsoft.Data.SqlClient` driver version. See the [7.0.2 release notes](../../../7.0/7.0.2.md) for the initial alignment announcement. This assembly ships with `FileVersion 7.1.0.x`. The `AssemblyVersion 7.0.0.0` remains unchanged from the `7.0.2` release.
+
+### Added
+
+#### Asynchronous key store provider APIs
+
+*What Changed:*
+
+- `SqlColumnEncryptionAzureKeyVaultProvider` now overrides the four asynchronous key store provider methods introduced on the base class in [#3673](https://github.com/dotnet/SqlClient/pull/3673): `EncryptColumnEncryptionKeyAsync`, `DecryptColumnEncryptionKeyAsync`, `SignColumnMasterKeyMetadataAsync`, and `VerifyColumnMasterKeyMetadataAsync`. These call the Azure SDK's own asynchronous methods and flow the supplied `CancellationToken` to them, rather than completing synchronous work on a returned task.
+- Concurrent cache misses for the same key are gated so a burst of callers issues a single Key Vault request. The gate is only ever awaited, so no thread blocks, and misses for different keys still proceed in parallel.
+  ([#4540](https://github.com/dotnet/SqlClient/pull/4540))
+
+*Who Benefits:*
+
+- Applications using Always Encrypted with Azure Key Vault can await column encryption key operations rather than blocking a thread pool thread on network-bound key vault I/O, when they call the provider directly.
+
+*Impact:*
+
+- No public API was removed or changed. The column encryption key and signature caches are shared between the synchronous and asynchronous paths, so a key resolved by one is visible to the other.
+- **Introduced, but not yet consumed by the driver.** `Microsoft.Data.SqlClient`'s own key resolution path still invokes the synchronous provider methods on both synchronous and asynchronous command execution, so these overrides do not by themselves make Always Encrypted query execution non-blocking. **A future release will enable their use from the driver's own asynchronous APIs.** See the core [7.1.0-preview3](../../../7.1/7.1.0-preview3.md) release notes.
+- **Behavior change:** `VerifyColumnMasterKeyMetadata` and `VerifyColumnMasterKeyMetadataAsync` now reject a null or empty `signature` with `ArgumentNullException` / `ArgumentException` instead of passing it through to the Azure SDK. In-product callers are unaffected because `SqlSecurityUtility.VerifyColumnMasterKeySignature` already rejects those values upstream.
+- **Runtime requirement:** this version requires `Microsoft.Data.SqlClient` 7.1.0-preview3 or later at runtime, because the overridden methods only exist on the 7.1 base class. The NuGet dependency floor covers restore, but downgrading the driver below 7.1 at runtime produces a `TypeLoadException`, since assembly versions unify at `major.0.0.0`.
+
+### Fixed
+
+- Fixed the 2000-entry column master key signature cache being able to stop compacting and grow unbounded. `LocalCache.GetOrCreate` compacted only when `Count == maxSize`, and under concurrency that equality test could be stepped past, permanently disabling compaction. It now compacts on `Count >= maxSize`. ([#4540](https://github.com/dotnet/SqlClient/pull/4540))
+- Fixed concurrent callers ending up with different `CryptographyClient` instances for the same key, which produced redundant clients and duplicated Key Vault handshakes. `GetCryptographyClient` now uses `GetOrAdd` instead of `TryGetValue` followed by `TryAdd`. ([#4540](https://github.com/dotnet/SqlClient/pull/4540))

-# Microsoft.Data.SqlClient Roadmap
-
-The Microsoft.Data.SqlClient roadmap communicates project priorities for evolving and extending the scope of the product. We encourage the community to work with us to improve SqlClient driver for these scenarios and extend it for others.
-
-## Released Versions
-
-- [Release Notes](release-notes/README.md) - For detailed release notes summarizing of all changes/features released.
-- [GitHub Releases](https://github.com/dotnet/sqlclient/releases) - For downloading NuGet Packages and identifying driver releases with changelog notes.
-
-## Upcoming Ship Dates
-
-For upcoming release dates, see [SqlClient milestones](https://github.com/dotnet/SqlClient/milestones).
-
-[SqlClient Projects](https://github.com/dotnet/SqlClient/projects) are used by our development team to define roadmap of prioritized work. SqlClient Boards contain issues, pull requests, and other features, development activities that are categorized as cards. Our goal is to be transparent over priorities, work in progress and deliverables.
-
-## Feedback
-
-The best way to give feedback is to create issues in the [dotnet/sqlclient](https://github.com/dotnet/sqlclient) repo.
-
-Although mostly obvious, please give us feedback that will give us insight on the following points:
-
-- Existing features are missing some capability or otherwise don't work well enough.
-- Missing features that should be added to the product.
-- Design choices for a feature that is currently in-progress.
-
-Some important caveats / notes:
-
-- It is best to give design feedback quickly for improvements that are in-development. We're unlikely to hold a feature being part of a release on late feedback.
-- We are most likely to include improvements that either have a positive impact on a broad scenario or have very significant positive impact on a niche scenario. This means that we are unlikely to prioritize modest improvements to niche scenarios.
-- Compatibility will almost always be given a higher priority than improvements.

+# Feature Specification: Pool Clear
+
+**Feature Branch**: `dev/mdaigle/connection-pool-designs`  
+**Created**: 2026-04-10  
+**Status**: Draft  
+**Input**: User description: "Implement Clear() in ChannelDbConnectionPool so that SqlConnection.ClearPool() and SqlConnection.ClearAllPools() work with pool v2, using a generation counter approach to lazily invalidate connections."
+
+## User Scenarios & Testing
+
+### User Story 1 - Clear a Specific Connection Pool
+
+As an application developer, I want to call `SqlConnection.ClearPool(connection)` to invalidate all connections in a specific pool, so that the next connection request creates a fresh physical connection (e.g., after a failover, credential rotation, or configuration change on the server).
+
+**Independent Test**: Can be tested by opening connections, calling `ClearPool`, then verifying that subsequent connection requests do not reuse pre-clear connections.
+
+**Acceptance Scenarios**:
+
+1. **Given** a pool with 10 idle connections, **When** `ClearPool` is called, **Then** all idle connections are closed and new connection requests create fresh physical connections.
+2. **Given** a pool with 5 busy (in-use) connections and 5 idle connections, **When** `ClearPool` is called, **Then** idle connections are closed immediately.
+
+---
+
+### User Story 2 - Clear All Connection Pools
+
+As an application developer, I want to call `SqlConnection.ClearAllPools()` to invalidate connections across all pools in the application, so that I can recover from broad infrastructure changes (e.g., DNS migration, certificate rollover).
+
+**Independent Test**: Can be tested by creating connections to multiple connection strings, calling `ClearAllPools`, and verifying all pools produce fresh connections.
+
+**Acceptance Scenarios**:
+
+1. **Given** multiple pools each with idle connections, **When** `ClearAllPools` is called, **Then** all idle connections across all pools are closed.
+
+---
+
+### User Story 3 - Lazy Invalidation of Busy Connections
+
+As the pool infrastructure, I need busy connections that were opened before a clear to be destroyed when they are returned to the pool, so that clearing does not interrupt active operations but still ensures all pre-clear connections are eventually removed.
+
+**Independent Test**: Can be tested by opening a connection, calling `ClearPool`, executing a query on the open connection (should succeed), closing the connection, then verifying the pool destroyed it rather than reusing it.
+
+**Acceptance Scenarios**:
+
+1. **Given** a connection opened and in use before a clear, **When** `ClearPool` is called, **Then** the connection continues to work normally.
+2. **Given** a connection opened and in use before a pool clear, **When** the connection is returned to the pool, **Then** the pool detects that it predates the clear and destroys it.
+3. **Given** a connection opened after a pool clear, **When** the connection is returned to the pool, **Then** it is returned to the idle channel normally.
+
+---
+
+### User Story 4 - Multiple Consecutive Clears
+
+As an application developer, I want multiple/concurrent calls to `ClearPool` to behave correctly, so that pool state is not corrupted.
+
+**Independent Test**: Can be tested by calling `ClearPool` multiple times in rapid succession and verifying no exceptions, no connection leaks, and correct pool behavior afterward.
+
+**Acceptance Scenarios**:
+
+1. **Given** a pool with connections, **When** `ClearPool` is called twice rapidly, **Then** both calls complete without error, and connections predating either clear are invalidated.
+
+---
+
+### Edge Cases
+
+- What happens if `ClearPool` is called on an empty pool? The generation counter increments but no connections are closed. Subsequent connections are fresh.
+- What happens if `ClearPool` is called during pool shutdown? The clear should be a no-op or complete harmlessly — shutdown already destroys all connections.
+- What happens with many clears causing generation counter overflow? With `int` counter, overflow at 2^31. Even at 1 clear/second, this is 68 years. Overflow is not a practical concern. If it wraps, the worst case is one stale connection survives a single retrieval cycle.
+- What happens if `ClearPool` is called during pool startup? `ClearPool` can be called at any time after the pool is instantiated. If connections are being added to the pool while clearing, they are closed subject to the conditions of the clear operation.
+- What happens if ClearPool is called while a SqlConnection is waiting to receive a connection from the pool? If a SqlConnection is waiting for a connection, then there are no idle connections in the pool, so `ClearPool` will not have any effect.
+
+## Requirements
+
+### Functional Requirements
+
+- **FR-002**: System MUST stamp each new connection with the current pool generation at creation time.
+- **FR-003**: System MUST reject connections whose generation does not match the current pool generation when they are retrieved from the idle channel or returned to the pool.
+- **FR-004**: System MUST drain all idle connections from the channel on `Clear()`, closing each one.
+- **FR-005**: System MUST NOT interrupt busy (in-use) connections during a clear — busy connections are destroyed lazily when returned.
+- **FR-006**: System MUST allow connections opened after a clear to be pooled normally.
+- **FR-007**: System MUST support concurrent calls to `Clear()` without corrupting pool state.
+- **FR-008**: System MUST integrate with the existing `SqlConnection.ClearPool()` and `SqlConnection.ClearAllPools()` call paths.
+
+### Key Entities
+
+- **Pool Generation Counter (`_clearGeneration`)**: A pool-level `volatile int` incremented atomically via `Interlocked.Increment` on each `Clear()` call. Represents the current "epoch" of the pool.
+- **Connection Generation (`ClearGeneration`)**: A property on `DbConnectionInternal` stamped when the connection is created or added to the pool. Used to compare against the pool's current generation.
+- **Stale Connection**: A connection whose `ClearGeneration` does not match the pool's `_clearGeneration`. Stale connections are destroyed rather than returned to the idle channel.
+
+## Success Criteria
+
+### Measurable Outcomes
+
+- **SC-001**: After `ClearPool` is called, 100% of subsequent connection acquisitions produce fresh physical connections (no pre-clear connections reused).
+- **SC-002**: Busy connections continue to operate normally during and after a pool clear — no active queries are interrupted.
+- **SC-003**: `ClearPool` and `ClearAllPools` work identically whether using pool v1 (WaitHandle) or pool v2 (Channel), from the caller's perspective.
+
+## Assumptions
+
+- The generation counter approach is preferred over the WaitHandle pool's `DoNotPoolThisConnection()` mark-all pattern because `ConnectionPoolSlots` is not iterable by design (CAS-based slot array).
+- `DbConnectionInternal` can accommodate a new `ClearGeneration` property without breaking existing functionality or requiring changes to the WaitHandle pool.
+- The existing `SqlConnection.ClearPool()` → `SqlConnectionFactory.ClearPool()` → `IDbConnectionPool.Clear()` call chain is already wired up and only requires the `ChannelDbConnectionPool.Clear()` implementation.
+- Transacted connections with stale generations are handled separately as part of the transactions feature and are out of scope for Phase 1 of pool clear.

+# Feature Specification: Async-Friendly Always Encrypted Support
+
+**Issue**: [#3672](https://github.com/dotnet/SqlClient/issues/3672)  
+**Feature Branch**: `dev/cheena/async-ae`  
+**Created**: 2026-05-13  
+**Status**: Draft  
+**Milestone**: 7.1.0-preview2  
+
+## Summary
+
+Eliminate sync-over-async in Always Encrypted (AE) code paths by adding async counterparts to all provider base classes and implementations, then rewiring async execution paths in SqlCommand to use them. Currently, async operations like `ExecuteReaderAsync` block ThreadPool threads when AE is enabled because all key decryption, signature verification, and enclave attestation calls are synchronous — including HTTP calls to Azure Key Vault and attestation services.
+
+## User Scenarios & Testing
+
+### User Story 1 — Async Key Decryption with Azure Key Vault
+
+As an application developer using Always Encrypted with Azure Key Vault, I want `ExecuteReaderAsync` to perform column encryption key (CEK) decryption asynchronously via the Azure Key Vault SDK, so that my async code paths do not block ThreadPool threads waiting for HTTP responses from Azure Key Vault.
+
+**Acceptance Scenarios**:
+
+1. **Given** a table with AE-encrypted columns and AKV-stored CMK, **When** `ExecuteReaderAsync` is called, **Then** CEK decryption calls `CryptographyClient.UnwrapKeyAsync()` instead of the sync `UnwrapKey()`.
+2. **Given** a `CancellationToken` passed to `ExecuteReaderAsync`, **When** the token is cancelled during AKV key decryption, **Then** the operation is cancelled and a `TaskCanceledException` is thrown.
+3. **Given** a custom provider that does NOT override async methods, **When** `ExecuteReaderAsync` is called, **Then** the base class fallback wraps the sync method in `Task.FromResult` and completes successfully.
+
+### User Story 2 — Async Enclave Attestation
+
+As an application developer using Always Encrypted with secure enclaves, I want enclave attestation to be performed asynchronously, so that HTTP calls to attestation services do not block my async query execution path.
+
+**Acceptance Scenarios**:
+
+1. **Given** an enclave-enabled query using Azure Attestation, **When** `ExecuteReaderAsync` is called, **Then** `ConfigurationManager<OpenIdConnectConfiguration>.GetConfigurationAsync()` is used.
+2. **Given** an enclave-enabled query using HGS attestation, **When** `ExecuteReaderAsync` is called, **Then** the HTTP call uses `await HttpClient.GetStreamAsync()` instead of `.Result`.
+
+### User Story 3 — Sync Path Preservation
+
+All existing sync methods are preserved as-is. The `isAsync` flag in `SqlCommand` determines which path is taken. Zero behavioral change for sync callers.
+
+### User Story 4 — Custom Provider Backward Compatibility
+
+Custom providers that only implement sync `DecryptColumnEncryptionKey` continue to work. The base class default wraps the sync call in `Task.FromResult`. If the sync method throws, the returned Task is faulted (not a synchronous throw).
+
+### Edge Cases
+
+- **Cache hit for CEK**: Async path returns immediately from cache without invoking the provider.
+- **Mixed sync/async on `SemaphoreSlim`**: For sites still using `SemaphoreSlim` (non-`IMemoryCache` caches), mixing `.Wait()` and `.WaitAsync()` is safe per .NET docs. For `IMemoryCache`-backed caches, the async path uses `GetOrCreateAsync` and does not need `SemaphoreSlim`.
+- **CancellationToken in default fallback**: The base class wraps sync methods and checks the token before invocation; sync calls themselves are not cancellable.
+- **Concurrent cache misses**: Two threads may independently fetch the same key. Last write wins (idempotent). See FR-014 for optional deduplication.
+- **Enclave session cache hit**: Returns from cache without performing attestation.
+- **`ColumnEncryptionKeyCacheTtl` mutation**: Property mutation must remain inside the semaphore-held section in `SqlSymmetricKeyCache` to avoid races.
+
+## Design Decisions
+
+### 1. `Task<T>` for Public APIs
+
+Public virtual methods use `Task<T>`, not `ValueTask<T>`. The primary beneficiary (AKV) always allocates a Task due to HTTP I/O. `ValueTask<T>` has stricter usage rules that would be error-prone for third-party implementers.
+
+### 2. `CancellationToken` with Default Value
+
+Each async method accepts a `CancellationToken cancellationToken = default` parameter. This is a single `virtual` overload — callers can omit the token for convenience, and derived classes override a single method. The default implementation checks the token for cancellation before invoking the synchronous method.
+
+### 3. Certificate/CNG/CSP Providers Keep Default Fallback
+
+No async overrides — these perform local crypto (CPU-bound) that doesn't benefit from async. The base class `Task.FromResult` fallback is sufficient.
+
+### 4. Async Methods Return Tuples Instead of `out` Parameters
+
+C# async methods cannot have `out` parameters. Internal enclave methods return tuples (e.g., `Task<(SqlEnclaveSession, long, byte[], int)>`). `SqlSecurityUtility.DecryptSymmetricKeyAsync` returns `Task<(SqlClientSymmetricKey Key, SqlEncryptionKeyInfo KeyInfoChosen)>`.
+
+### 5. `ConfigureAwait(false)` on Every `await`
+
+Every `await` in library code MUST use `.ConfigureAwait(false)`. Omission causes deadlocks in ASP.NET Framework, WPF, and WinForms hosts. This is a hard correctness requirement enforced in CI.
+
+### 6. `MemoryCache.GetOrCreateAsync` for Async Cache Patterns
+
+**API**: [`CacheExtensions.GetOrCreateAsync<TItem>(IMemoryCache, Object, Func<ICacheEntry, Task<TItem>>)`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.caching.memory.cacheextensions.getorcreateasync?view=net-10.0-pp)
+
+For `IMemoryCache`-backed caches, use `GetOrCreateAsync` with an async factory delegate instead of `SemaphoreSlim` + manual `TryGetValue`/`Set`. This eliminates lock-during-I/O without requiring the check-release-fetch-relock pattern.
+
+```csharp
+var result = await _cache.GetOrCreateAsync(cacheKey, async entry =>
+{
+    entry.SlidingExpiration = _columnEncryptionKeyCacheTtl;
+    return await provider.DecryptColumnEncryptionKeyAsync(
+        masterKeyPath, algorithm, encryptedKey, ct)
+        .ConfigureAwait(false);
+}).ConfigureAwait(false);
+```
+
+**Affected**: `SqlColumnEncryptionAzureKeyVaultProvider._columnEncryptionKeyCache`
+
+For sites NOT using `IMemoryCache` (custom `Dictionary`/`ConcurrentDictionary` caches), use the check-release-fetch-relock pattern with `SemaphoreSlim`:
+
+```csharp
+await semaphore.WaitAsync(ct).ConfigureAwait(false);
+try
+{
+    if (cache.TryGetValue(key, out var cached))
+        return cached;
+}
+finally { semaphore.Release(); }  // release BEFORE I/O
+
+var value = await FetchAsync(key, ct).ConfigureAwait(false);
+
+await semaphore.WaitAsync(ct).ConfigureAwait(false);
+try { cache.Set(key, value); }
+finally { semaphore.Release(); }
+return value;
+```
+
+**Affected**: `SqlSymmetricKeyCache._cacheLock`, `AzureSqlKeyCryptographer._keyDictionarySemaphore`
+
+### 7. `GetParameterEncryptionDataReaderAsync` Must Be True `async Task`
+
+Remove the `Task.Run(() => { ... })` wrapper entirely. The method must `await` each I/O step directly using clean `async/await`, not the `AsyncHelper.ContinueTaskWithState` callback pattern.
+

+| FR-001 | Add `virtual` async counterparts for `DecryptColumnEncryptionKey`, `EncryptColumnEncryptionKey`, `SignColumnMasterKeyMetadata`, and `VerifyColumnMasterKeyMetadata` to `SqlColumnEncryptionKeyStoreProvider`. |
+| FR-002 | Each async method accepts `CancellationToken cancellationToken = default` as a single virtual overload. Default checks token before sync fallback. |
+| FR-003 | Default async implementations wrap sync via `Task.FromResult`; return faulted Tasks (not synchronous throws) on exception. |
+| FR-004 | `SqlColumnEncryptionAzureKeyVaultProvider` overrides all 4 async methods with truly async Azure SDK calls. |
+| FR-005 | AKV provider propagates `CancellationToken` to all Azure SDK calls. |
+| FR-006 | Internal async counterparts added to enclave provider base class and all implementations. |
+| FR-007 | Enclave providers with HTTP I/O (Azure Attestation, HGS) implement truly async attestation. |
+| FR-008 | Async utility methods added: `SqlSecurityUtility.DecryptSymmetricKeyAsync` (returns tuple), `VerifyColumnMasterKeySignatureAsync`, `SqlSymmetricKeyCache.GetKeyAsync`. All propagate `CancellationToken`. |
+| FR-009 | `SqlCommand` async paths use async AE methods when `isAsync=true`. `GetParameterEncryptionDataReaderAsync` becomes true `async Task`. |
+| FR-010 | No changes to existing sync code paths or behavior. |
+| FR-011 | All new public APIs declared in `src/Microsoft.Data.SqlClient/ref/Microsoft.Data.SqlClient.cs`. |
+| FR-012 | Async caching: `IMemoryCache` sites use `GetOrCreateAsync`; custom-cache sites use check-release-fetch-relock with `SemaphoreSlim`. No lock held during I/O. |
+| FR-013 | Every `await` uses `.ConfigureAwait(false)`. Enforced in CI. |
+| FR-014 | Concurrent cache misses tolerated without deadlock. Last write wins. Optional deduplication via `ConcurrentDictionary<key, Task<value>>`. |
+| FR-015 | `lock(enclaveCacheLock)` replaced with `SemaphoreSlim` if async operations must run before session storage. Sync-only paths may retain `lock`. |

+
+## Implementation Phases
+
+### Phase 1: Base Class API (PR #3673 — in progress)
+
+*Depends on: nothing*
+
+Add 4 virtual async methods + 4 convenience overloads to `SqlColumnEncryptionKeyStoreProvider`, update ref assemblies and XML docs.
+
+**Files**:
+- `src/Microsoft.Data.SqlClient/src/Microsoft/Data/SqlClient/SqlColumnEncryptionKeyStoreProvider.cs`
+- `src/Microsoft.Data.SqlClient/ref/Microsoft.Data.SqlClient.cs`
+- `doc/snippets/Microsoft.Data.SqlClient/SqlColumnEncryptionKeyStoreProvider.xml`
+
+### Phase 2: Key Store Provider Implementations
+
+*Depends on: Phase 1. Parallel with Phase 3.*
+
+#### 2A. AzureKeyVaultProvider (truly async)
+
+- `AzureSqlKeyCryptographer.cs` — Add async counterparts using Azure SDK. `AddKeyAsync` uses check-release-fetch-relock on `_keyDictionarySemaphore` (uses `Dictionary`, not `IMemoryCache`).
+- `SqlColumnEncryptionAzureKeyVaultProvider.cs` — Override 4 async methods. Use `GetOrCreateAsync` on `_columnEncryptionKeyCache`:
+
+**Async key-unwrap flow**:
+1. `await _columnEncryptionKeyCache.GetOrCreateAsync(cacheKey, async entry => { ... }).ConfigureAwait(false)`
+2. Inside factory: `await KeyCryptographer.UnwrapKeyAsync(..., ct).ConfigureAwait(false)` — I/O runs without user-managed locks
+3. Configure entry expiration via `ICacheEntry`
+4. `MemoryCache` handles cache insertion
+
+The sync path remains unchanged (`_cacheSemaphore.Wait()` + `GetOrCreate`). `GetOrCreateSignatureVerificationResult` stays sync (CPU-bound RSA).
+
+#### 2B–2D. CertificateStore, CNG, CSP Providers
+
+No changes — default base class fallback is sufficient.
+
+### Phase 3: Enclave Provider Async APIs
+
+*Depends on: nothing. Parallel with Phase 2.*
+
+- `SqlColumnEncryptionEnclaveProvider.cs` — 4 internal abstract async methods
+- `EnclaveProviderBase.cs` — `GetEnclaveSessionHelperAsync()`
+- `EnclaveSessionCache.cs` — Replace `lock` with `SemaphoreSlim` where async operations precede session storage (FR-015)
+- `NoneAttestationEnclaveProvider.cs` — Sync wrappers (no real I/O)
+- `AzureAttestationBasedEnclaveProvider.cs` — Truly async (`GetConfigurationAsync()`)
+- `VirtualSecureModeEnclaveProviderBase.cs` — Abstract `MakeRequestAsync`, `VerifyAttestationInfoAsync`
+- `VirtualSecureModeEnclaveProvider.cs` — Truly async (`HttpClient.GetStreamAsync`)
+- `EnclaveDelegate.Crypto.cs` — Async dispatcher methods
+
+### Phase 4: Async Utility Layer
+
+*Depends on: Phase 1.*
+
+- `SqlSecurityUtility.cs`:
+  - `DecryptSymmetricKeyAsync` → returns `Task<(SqlClientSymmetricKey Key, SqlEncryptionKeyInfo KeyInfoChosen)>`
+  - `GetKeyFromLocalProvidersAsync` — propagates `CancellationToken`
+  - `VerifyColumnMasterKeySignatureAsync` — propagates `CancellationToken`
+- `SqlSymmetricKeyCache.cs`:
+  - `GetKeyAsync` — check-release-fetch-relock on static `_cacheLock`; propagates `CancellationToken`
+
+> **Note**: Phases 1–4 deliver async infrastructure. End-to-end benefit requires Phase 5.
+
+### Phase 5: Async Call-Site Integration
+
+*Depends on: Phase 4.*
+
+- `SqlCommand.Encryption.cs`:
+  1. `ReadDescribeEncryptionParameterResultsKeysAsync` → `VerifyColumnMasterKeySignatureAsync()`
+  2. `ReadDescribeEncryptionParameterResultsMetadataAsync` → `DecryptSymmetricKeyAsync()` (**highest impact**)
+  3. `ReadDescribeEncryptionParameterResultsAsync` → orchestrates above
+  4. **Refactor `GetParameterEncryptionDataReaderAsync`** into true `async Task` — remove `Task.Run` wrapper
+  5. `TryFetchInputParameterEncryptionInfoAsync` → `EnclaveDelegate.GetEnclaveSessionAsync()`
+
+### Phase 6: Testing & Documentation
+
+*Spans all phases.*
+
+**Unit Tests** (`tests/UnitTests/`): Default fallback, cancellation, faulted Tasks  
+**Functional Tests** (`tests/FunctionalTests/`): `DummyKeyStoreProvider` async overrides  
+**Manual Tests** (`tests/ManualTests/`): AKV end-to-end, enclave attestation async, encrypted query async  
+**CI Gate**: Roslyn analyzer or grep check for `.ConfigureAwait(false)` on every `await`  
+**Documentation**: XML docs, `doc/samples/` async AE examples
+
+## New Public API Surface
+
+### SqlColumnEncryptionKeyStoreProvider
+
+```csharp
+public abstract class SqlColumnEncryptionKeyStoreProvider
+{
+    // Existing (unchanged)
+    public abstract byte[] DecryptColumnEncryptionKey(string masterKeyPath, string encryptionAlgorithm, byte[] encryptedColumnEncryptionKey);
+    public abstract byte[] EncryptColumnEncryptionKey(string masterKeyPath, string encryptionAlgorithm, byte[] columnEncryptionKey);
+    public virtual byte[] SignColumnMasterKeyMetadata(string masterKeyPath, bool allowEnclaveComputations);
+    public virtual bool VerifyColumnMasterKeyMetadata(string masterKeyPath, bool allowEnclaveComputations, byte[] signature);
+    public virtual TimeSpan? ColumnEncryptionKeyCacheTtl { get; set; }
+
+    // NEW: Async with optional CancellationToken (virtual, overridable)
+    public virtual Task<byte[]> DecryptColumnEncryptionKeyAsync(string masterKeyPath, string encryptionAlgorithm, byte[] encryptedColumnEncryptionKey, CancellationToken cancellationToken = default);
+    public virtual Task<byte[]> EncryptColumnEncryptionKeyAsync(string masterKeyPath, string encryptionAlgorithm, byte[] columnEncryptionKey, CancellationToken cancellationToken = default);
+    public virtual Task<byte[]> SignColumnMasterKeyMetadataAsync(string masterKeyPath, bool allowEnclaveComputations, CancellationToken cancellationToken = default);
+    public virtual Task<bool> VerifyColumnMasterKeyMetadataAsync(string masterKeyPath, bool allowEnclaveComputations, byte[] signature, CancellationToken cancellationToken = default);
+}
+```
+
+### SqlColumnEncryptionAzureKeyVaultProvider
+
+```csharp
+public class SqlColumnEncryptionAzureKeyVaultProvider : SqlColumnEncryptionKeyStoreProvider
+{
+    // Overrides — truly async via Azure SDK
+    public override Task<byte[]> DecryptColumnEncryptionKeyAsync(..., CancellationToken cancellationToken = default);
+    public override Task<byte[]> EncryptColumnEncryptionKeyAsync(..., CancellationToken cancellationToken = default);
+    public override Task<byte[]> SignColumnMasterKeyMetadataAsync(..., CancellationToken cancellationToken = default);
+    public override Task<bool> VerifyColumnMasterKeyMetadataAsync(..., CancellationToken cancellationToken = default);
+}
+```
+
+## Success Criteria
+
+| ID | Criterion |
+|----|-----------|
+| SC-001 | `ExecuteReaderAsync` with AE + AKV does NOT block any ThreadPool thread on HTTP I/O. |
+| SC-002 | All existing AE tests pass unchanged — zero sync regressions. |
+| SC-003 | `Task.Run` is no longer used in `GetParameterEncryptionDataReaderAsync`. |
+| SC-004 | `CancellationToken` propagates from `SqlCommand` async methods through to Azure SDK calls. |
+| SC-005 | Custom providers with only sync implementations continue to work in async paths. |
+
+## Assumptions
+
+- Azure SDK async methods (`UnwrapKeyAsync`, `WrapKeyAsync`, etc.) are stable and production-ready.
+- `SemaphoreSlim` supports mixed `.Wait()` / `.WaitAsync()` on the same instance.
+- `SqlColumnEncryptionEnclaveProvider` is internal — API changes have no public impact.
+- The existing `isAsync` flag in `SqlCommand` determines sync vs async AE paths.
+- PR #3673 has not shipped — adding `CancellationToken` is non-breaking.
+- Certificate/CNG/CSP providers perform local crypto; `Task.FromResult` is sufficient.
+- `Microsoft.Extensions.Caching.Abstractions` (already referenced by AKV provider) provides `GetOrCreateAsync`.
+
+## Further Considerations
+
+1. **`ConfigureAwait(false)` CI enforcement**: Add a Roslyn analyzer or grep-based check to prevent regressions.
+2. **Third-party provider guidance**: Document how custom providers should override async methods, use `ConfigureAwait(false)`, support cancellation, and avoid lock-during-I/O.
+3. **Performance benchmarking**: After Phase 5, quantify ThreadPool savings and latency improvements under load.
+4. **In-flight request deduplication**: Optional `ConcurrentDictionary<string, Task<byte[]>>` for concurrent cold-cache AKV requests (FR-014).
+5. **`ValueTask<T>` for internal fast paths**: Internal methods like `SqlSymmetricKeyCache.GetKeyAsync` have high cache-hit rates — `ValueTask<T>` avoids Task allocations. P2 optimization with no API impact.

+# Feature Specification: Background Pool Warmup
+
+**Feature Branch**: `dev/mdaigle/pool-warmup` (branched from `dev/mdaigle/pool-channel-rate-limiting`)  
+**Created**: 2026-07-16  
+**Status**: Draft  
+
+## Description
+
+Implement background pool warmup for `ChannelDbConnectionPool`. When the pool starts, it asynchronously pre-creates connections up to Min Pool Size in the background, serially (one at a time), through the shared rate-limiting mechanism used by user-initiated requests.
+
+Whenever the pool count drops below Min Pool Size for any reason (a connection destroyed on return, idle-timeout eviction, or any other removal that crosses the floor), the pool automatically triggers replenishment using the same serial, rate-limited creation path. Pruning itself respects the Min Pool Size floor and never reduces the pool below the minimum; it is only mentioned here because it shares the same removal choke point that triggers replenishment.
+
+## User Scenarios & Testing
+
+### User Story 1 — Background Warmup on Pool Creation (P1)
+
+When a pool is created with Min Pool Size > 0, it pre-creates connections in the background so early application requests find ready-to-use connections.
+
+**Acceptance Scenarios**:
+
+1. **Given** a pool is created with minimum pool size of N, **When** startup completes, **Then** the pool begins creating connections in the background up to N.
+2. **Given** a pool is warming up, **When** a user opens a connection before warmup finishes, **Then** the user request is served immediately without waiting for warmup to complete.
+3. **Given** a pool is warming up, **When** warmup creates each connection, **Then** each connection is created one at a time (serially), not in parallel.
+
+---
+
+### User Story 2 — Warmup Through Shared Rate Limiter (P1)
+
+Warmup creates connections through the same rate-limiting mechanism as user-initiated requests, preventing warmup from overwhelming the server.
+
+**Acceptance Scenarios**:
+
+1. **Given** warmup is creating connections, **When** a user request also needs a new connection, **Then** both warmup and user requests compete fairly through the shared rate limiter.
+2. **Given** the rate limiter is at capacity, **When** warmup attempts to create the next connection, **Then** warmup does not bypass the limiter: it ends the current pass without creating (rather than spinning or waiting on a permit). Saturation only occurs while user requests are actively creating connections, which fill the pool themselves; any later drop below the minimum re-triggers warmup once capacity has freed up.
+
+---
+
+### User Story 3 — Warmup Failure Resilience (P1)
+
+If a connection fails to open during warmup, the failure is silently absorbed on the warmup loop — it is never propagated to the caller as an unhandled exception. Warmup participates in the pool's blocking-period error state exactly like an on-demand creation (mirroring the legacy WaitHandle pool): a genuine open failure enters the error state, and a successful open clears it. The pool remains operational — once the blocking period expires, user requests create connections on demand as needed.
+
+**Acceptance Scenarios**:
+
+1. **Given** warmup is in progress, **When** a connection fails to open, **Then** the failure is traced/logged and absorbed by the warmup loop rather than surfacing as an unhandled exception.
+2. **Given** warmup fails and has entered the blocking-period error state, **When** a user opens a connection during the blocking window, **Then** the user request fast-fails with the cached exception (matching the WaitHandle pool); once the blocking period expires it creates a connection on demand and succeeds normally.
+3. **Given** warmup's open fails, **When** the pool's error state is checked, **Then** the pool IS in the blocking-period error state — warmup uses the same shared creation path as user requests and enters/clears that state identically.
+4. **Given** the pool is already in the blocking-period error state (driven there by a failing request), **When** warmup would otherwise replenish, **Then** warmup stands down while the error state is active rather than piling more doomed opens onto a struggling server (the warmup loop skips replenishment while `ErrorOccurred`, mirroring the WaitHandle pool).
+
+---
+
+### User Story 4 — Warmup Cancellation on Shutdown (P2)
+
+When a pool is shut down while warmup is still in progress, warmup stops promptly. No new connections are created after shutdown begins.
+
+**Acceptance Scenarios**:
+
+1. **Given** warmup is in progress, **When** the pool is shut down, **Then** warmup stops and no further connections are created.
+2. **Given** warmup is in progress, **When** the pool is shut down, **Then** any connections already created by warmup are cleaned up as part of normal shutdown.
+
+---
+
+### User Story 5 — Replenishment on Any Below-Minimum Event (P2)
+
+Whenever the pool count drops below Min Pool Size, the pool automatically triggers warmup-style replenishment to restore to the minimum. Every connection removal funnels through a single choke point (`RemoveConnection`), which triggers replenishment when the removal leaves the pool below the minimum.
+
+**Acceptance Scenarios**:
+
+1. **Given** a pruning cycle runs, **When** it removes idle connections, **Then** it stops at the Min Pool Size floor and does not reduce the pool below the minimum (pruning shares the removal choke point but does not itself cause a below-minimum replenishment).
+2. **Given** a connection is destroyed on return to the pool (broken, lifetime expired), **When** the pool count drops below the minimum, **Then** the pool queues a replenishment request.
+3. **Given** idle-timeout eviction removes an expired connection on retrieval, **When** the pool count drops below minimum, **Then** the pool queues a replenishment request.
+4. **Given** replenishment is triggered, **When** connections are created, **Then** they are created serially through the shared rate limiter, identical to initial warmup.
+5. **Given** the pool is at or above the minimum pool size, **When** a connection is destroyed, **Then** no replenishment is triggered.
+
+## Implementation Notes
+
+- Warmup starts automatically when the pool's `Startup()` is called.
+- Warmup runs on a background task, so it never blocks the caller (`Startup`/connection return) and uses no sync-over-async in the loop. The physical connection open itself is currently synchronous (executed on the background task); the connection factory does not yet expose an async open.
+- Creates connections serially (one at a time) through the shared rate limiter. If the limiter is saturated (no permit available), warmup ends the pass rather than bypassing or spinning on the limiter; convergence to the minimum is handled by the concurrent user creations that saturated it and by re-triggering on the next below-minimum event.
+- Warmup failures are traced/logged and absorbed by the warmup loop (never surfaced as an unhandled exception). Warmup goes through the same shared creation path as user requests, so a genuine open failure enters the blocking-period error state and a successful open clears it (mirroring the WaitHandle pool). While the error state is active, the warmup loop stands down rather than replenishing.
+- If a `Clear` races with an in-flight warmup creation, the freshly created (now stale-generation) connection is not special-cased by warmup; it is harmlessly discarded by the liveness/generation check on its next retrieval. After a `Clear`, replenishment refills the pool to the minimum with fresh-generation connections.
+- Idle-timeout eviction is lazy: an idle connection past its timeout is removed when it is next retrieved (via the liveness check), not by a background sweep. Pruning is separate and always respects the Min Pool Size floor.
+- Concurrent warmup/replenishment requests are coalesced — a single `_warmupLoopRunning` guard ensures only one warmup loop executes at a time, and requests that arrive while it is running are dropped (the running loop re-reads the pool count each iteration and drives to the minimum on its own).
+- Warmup is a no-op when Min Pool Size = 0.
+
+## Acceptance Criteria
+
+- When a pool starts with Min Pool Size > 0, background warmup begins immediately.
+- After warmup completes, the pool contains Min Pool Size idle connections.
+- Warmup runs on a background task without blocking callers and without sync-over-async in the loop (the physical open is currently synchronous, executed on the background task, pending async-open support in the factory).
+- Warmup connections are created serially through the shared rate limiter.
+- Warmup errors are traced/logged and never crash the application. Because warmup shares the on-demand creation path, a genuine open failure enters the pool's blocking-period error state (as it would for a user request) and a successful open clears it.
+- If the pool is shut down or cleared during warmup, warmup stops gracefully.
+- After any event that reduces the pool below Min Pool Size, the pool restores to the minimum through replenishment: a single warmup pass suffices when it is not racing a concurrent drain (e.g. `Clear`) or a saturated rate limiter; otherwise convergence completes across subsequent re-triggered passes.
+- Concurrent warmup/replenishment requests are coalesced so only one warmup loop executes at a time.
+- Unit tests validate warmup behavior for various Min Pool Size values (0, 1, N) and all replenishment triggers.

+# Feature Specification: Pool Rate Limiting and Blocking Period
+
+**Feature Branch**: `dev/mdaigle/pool-rate-limit`
+**Created**: 2026-05-19
+**Status**: Draft
+**Input**: ADO Work Item 37824 — "Implement connection open rate limiting"
+
+## Description
+
+Add rate limiting to `ChannelDbConnectionPool` to control how many physical connections can be
+created concurrently. Without throttling, a burst of concurrent requests can trigger a login
+storm against SQL Server. The implementation uses
+`System.Threading.RateLimiting.ConcurrencyLimiter` from the BCL — no custom rate limiting
+primitives are defined.
+
+This feature also adds the `PoolBlockingPeriod` error state (fast-fail after a connection
+creation failure) with exponential backoff recovery, matching the existing
+`WaitHandleDbConnectionPool` behavior.
+
+> Time spent waiting for the rate limiter counts against the caller's overall `ConnectTimeout`
+> budget. `ReplaceConnection` (when implemented) MUST bypass the rate limiter: it already holds
+> a pool slot and must not deadlock.
+
+## User Scenarios & Testing
+
+### User Story 1 — Throttled Connection Creation Under Burst Demand (P1)
+
+The pool limits the number of simultaneous physical connection creation attempts. Callers that
+cannot immediately create a connection do not queue on the limiter; they fall back to waiting on
+the idle channel, where they are satisfied either by a returned connection or by a best-effort
+wake when another caller releases its permit. The idle channel preserves FIFO order for returned
+connections, but rate-limit retries are best-effort rather than strictly ordered. All waiting is
+subject to the caller's `ConnectTimeout`.
+
+**Acceptance Scenarios**:
+
+1. **Given** the pool has no idle connections and many callers request connections simultaneously,
+   **When** the concurrency limit is reached, **Then** additional callers wait until an in-flight
+   creation completes before starting their own.
+2. **Given** a caller is waiting for the rate limiter, **When** its `ConnectTimeout` elapses,
+   **Then** the caller receives a timeout error without ever attempting to create a connection.
+3. **Given** the rate limiter has available capacity, **When** a caller requests a new connection,
+   **Then** the create proceeds immediately with no added latency.
+4. **Given** a connection creation completes (success or failure), **When** the `RateLimitLease`
+   is disposed, **Then** the next waiting caller is allowed to proceed.
+
+---
+
+### User Story 2 — Blocking Period Fast-Fail on Connection Failure (P1)
+
+When a connection creation attempt fails because the server is unreachable, the pool enters an
+error state and immediately fails subsequent requests for a limited period, returning the cached
+error. This prevents cascading timeouts when the server is down.
+
+**Acceptance Scenarios**:
+
+1. **Given** a creation failure has occurred and blocking period is enabled, **When** a new
+   connection is requested within the blocking window, **Then** the request fails immediately
+   with the cached error.
+2. **Given** a creation failure has occurred and blocking period is enabled, **When** the
+   blocking window expires, **Then** the next request attempts fresh connection creation.
+3. **Given** `PoolBlockingPeriod=NeverBlock`, **When** a creation failure occurs, **Then** each
+   subsequent request independently attempts creation (no fast-fail).
+4. **Given** `PoolBlockingPeriod=Auto` connecting to an Azure SQL endpoint and a failure occurs,
+   **Then** no blocking period is applied (same as `NeverBlock`).
+5. **Given** `PoolBlockingPeriod=Auto` connecting to an on-premises SQL Server and a failure
+   occurs, **Then** the blocking period is applied (same as `AlwaysBlock`).
+
+---
+
+### User Story 3 — Error State Recovery with Exponential Backoff (P2)
+
+While in the error state the pool waits using exponential backoff (5s → 10s → 20s → 30s → 60s
+cap) before allowing the next attempt. Once an attempt after the backoff succeeds, the error
+state clears and backoff resets.
+
+**Acceptance Scenarios**:
+
+1. **Given** the pool is in error state, **When** the backoff timer fires and the next caller's
+   attempt succeeds, **Then** the error state is cleared and subsequent requests attempt normal
+   creation.
+2. **Given** the pool is in error state, **When** the backoff timer fires and the next caller's
+   attempt fails, **Then** the backoff interval increases (up to the 60s cap) and the pool
+   re-enters the error state.
+3. **Given** the pool is in error state, **When** the error is cleared, **Then** the cached
+   exception, the error flag, and the backoff interval are all reset.
+
+---
+
+### User Story 4 — Rate Limiting Counts Against Connection Timeout (P2)
+
+Time spent waiting for rate limiter capacity counts against the caller's overall
+`ConnectTimeout` budget.
+
+**Acceptance Scenarios**:
+
+1. **Given** a caller's timeout is 15s and the caller waits 10s for rate limiting, **When** the
+   rate limiter releases, **Then** the remaining budget for connection creation is 5s.
+2. **Given** a caller's timeout expires while waiting for the rate limiter, **When** the timeout
+   fires, **Then** the caller receives a timeout error and is removed from the limiter queue.
+
+---
+
+### User Story 5 — Rate Limiting Built on a Concurrency Limiter (P3)
+
+The pool supports an optional `System.Threading.RateLimiting.ConcurrencyLimiter` to throttle
+concurrent physical connection creation. This is the only limiter type the pool currently needs
+(pooling against on-prem SQL Server), so the pool takes a concrete `ConcurrencyLimiter?` rather
+than the abstract `RateLimiter` base. Support for other limiter types can be added later if a
+concrete need arises. When no limiter is supplied (`null`), no rate limiting is applied.
+
+**Acceptance Scenarios**:
+
+1. **Given** the pool is configured with a `ConcurrencyLimiter`, **When** connections
+   are created, **Then** the limiter throttles concurrent creation to the configured maximum.
+2. **Given** no limiter is supplied (`null`), **When** connections are created, **Then** the
+   pool applies no rate limiting.
+
+---
+
+## Functional Requirements
+
+- **FR-001**: The pool MUST limit the number of concurrent physical connection creation attempts
+  to a configurable maximum.
+- **FR-002**: Callers that cannot immediately create a connection due to rate limiting MUST fall
+  back to waiting on the idle channel until capacity becomes available (via a returned connection
+  or a best-effort wake when a permit is released) or their timeout expires. Rate-limit retries are
+  best-effort and not strictly FIFO-ordered.
+- **FR-003**: Time spent waiting for rate limiter capacity MUST count against the caller's
+  overall connection timeout budget.
+- **FR-004**: When a connection creation attempt completes (success or failure), the
+  `RateLimitLease` MUST be disposed so the next waiting caller can proceed.
+- **FR-005**: The pool MUST support three `PoolBlockingPeriod` modes: `Auto`, `AlwaysBlock`, and
+  `NeverBlock`.
+- **FR-006**: When the blocking period is enabled, the pool MUST enter an error state after a
+  creation failure and immediately fail subsequent requests with the cached error.
+- **FR-007**: When the blocking period is disabled, the pool MUST NOT enter an error state;
+  each request MUST independently attempt creation.
+- **FR-008**: While in error state, the backoff MUST use exponential growth starting at 5s,
+  doubling each attempt, capped at 60s.
+- **FR-009**: When an attempt succeeds, the pool MUST clear the error state and reset the
+  backoff to its initial value.
+- **FR-010**: The `ErrorOccurred` property MUST return `true` when in the error state and
+  `false` otherwise.
+- **FR-011**: `ClearPool` MUST clear the error state in addition to invalidating pooled
+  connections.
+- **FR-012**: The rate limiter MUST be an optional `System.Threading.RateLimiting.ConcurrencyLimiter`.
+  When no limiter is supplied (`null`), the pool MUST apply no rate limiting. Support for other
+  `RateLimiter` types is intentionally out of scope for now and may be added later if needed.
+- **FR-013**: When a limiter is supplied, it MUST be a
+  `System.Threading.RateLimiting.ConcurrencyLimiter` configured with the desired maximum number
+  of concurrent connection creation attempts.

+
+    Why an intermediate nuspec is generated:
+    * The source nuspec keeps dependency versions as tokens to stay template-driven.
+    * During SDK-style packing, dependency token substitution is not consistently applied in this flow.
+    * Expanding tokens up front guarantees deterministic dependency versions in the final package metadata.
+
+    Why sibling package versions are resolved here:
+    * Pack entrypoints may call this project directly and omit Abstractions/Logging version overrides.
+    * Those versions must still align with sibling projects' versioning rules (BuildNumber/BuildSuffix and defaults).
+    * Conditional imports of sibling Versions.props preserve a single source of version truth.
+
+    Known SDK behavior (SDK 10.0.107):
+    * Tokens in NuspecProperties are substituted for string-valued metadata fields (for example $Version$).
+    * Tokens used as dependency version attribute values are not reliably substituted in this flow, which can
+      surface as: "An error occurred while trying to parse the value '' of property 'dependencies' in the
+      manifest file" and "'' is not a valid version string."
+    * Pre-materializing dependency version tokens into the generated intermediate nuspec avoids this failure.

+/// Provides platform detection flags for OS-specific code paths.
+/// </summary>
+/// <remarks>
+/// This type exists to keep OS detection terse and in one place: callers write
+/// <c>OsConstants.IsWindows</c> instead of repeating <c>RuntimeInformation.IsOSPlatform(...)</c>
+/// throughout the codebase.  Centralizing it also gives us a single seam to adjust if a specific
+/// OS needs special handling (for example, a different detection mechanism, a finer-grained
+/// flag, or an override for testing) without touching every call site.
+/// </remarks>
+/// <remarks>
+/// Each flag is exposed as a property that directly returns an OS check.  On .NET, that check is
+/// <c>OperatingSystem.Is*()</c>, which the JIT treats as an intrinsic and constant-folds (and which
+/// the IL trimmer also recognizes).  On .NET Framework — where the <see cref="System.OperatingSystem"/>
+/// platform-check helpers do not exist — the check falls back to
+/// <see cref="RuntimeInformation.IsOSPlatform"/>.  Either way, returning the check directly is
+/// deliberate: caching the results in static fields (for example, via a static constructor) would
+/// defeat both the JIT folding and the trimmer — the trimmer cannot analyze a static constructor,
+/// so it would be unable to prove which branches are dead and would keep OS-specific code (including
+/// Windows-only native dependencies) in apps published for other platforms.
+/// </remarks>
+/// <remarks>
+/// <para>
+/// IL trimming note: when a downstream app is published for a specific OS (a RID-specific publish),
+/// the IL trimmer substitutes the underlying <see cref="RuntimeInformation.IsOSPlatform"/> /
+/// <c>OperatingSystem.Is*</c> checks with constant <c>true</c>/<c>false</c> for the target OS and
+/// then removes the dead branch (along with everything it transitively references, such as
+/// Windows-only native entry points).  This is what lets a single cross-platform assembly trim
+/// away the OS-specific code that does not apply to the published target.
+/// </para>
+/// <para>
+/// For this to work, each guard must be used <b>inline</b> in the same method as the OS-specific
+/// code it gates.  The trimmer's constant folding is shallow: it reasons within the method that
+/// contains the guard, so a guard hidden behind a helper traps the constant inside that helper and
+/// leaves the protected code reachable (and therefore not trimmed).
+/// </para>
+/// <para>
+/// Do — guard inline, so the trimmer can drop the branch and its dependencies:
+/// <code>
+/// if (OsConstants.IsWindows)
+/// {
+///     WindowsOnlyNativeCall();   // becomes `if (false) { ... }` off-Windows, then removed
+/// }
+/// </code>
+/// </para>
+/// <para>
+/// Don't — hide the guard in a throw helper; the trimmer cannot prove the call below is dead:
+/// <code>
+/// static void ThrowIfNotWindows()
+/// {
+///     if (!OsConstants.IsWindows) throw new PlatformNotSupportedException();
+/// }
+/// // caller:
+/// ThrowIfNotWindows();
+/// WindowsOnlyNativeCall();   // still reachable to the trimmer; kept even off-Windows

+/// * In "act" section of test, call and await the method under test
+/// * Call and await <see cref="Wait"/> and supply with suitable timeout, capturing the returned
+///   exception, if any.
+/// * Assert that the expected outcome occurred (in the "assert" section of the test). If exception
+///   was expected, ensure the returned exception is not <see langword="null"/>. Otherwise, ensure
+///   the returned exception is <see langword="null"/>.

+# PackageCompatibility Tool
+
+A minimal console application that verifies that a set of SqlClient packages can coexist without
+transitive dependency conflicts, API surface mismatches, or broken runtime functionality.  It forces
+the AKV provider type to load (pulling in that assembly and its transitive dependencies) and then
+opens a `SqlConnection` to confirm that the resolved package graph works end-to-end against a real
+SQL Server instance.
+
+The following SqlClient packages are verified, either directly or transitively:
+
+- `Microsoft.Data.SqlClient`
+- `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider`
+- `Microsoft.Data.SqlClient.Internal.Logging`
+- `Microsoft.Data.SqlClient.Extensions.Abstractions`
+- `Microsoft.Data.SqlClient.Extensions.Azure` *(optional — included when `AzureVersion` is set)*
+- `Microsoft.SqlServer.Server`
+
+## Purpose
+
+This tool is a smoke test for inter-package compatibility across the SqlClient suite.  It catches
+problems such as:
+
+- Assembly binding conflicts caused by mismatched transitive dependencies.
+- API surface mismatches between independently-versioned packages.
+- Runtime failures that only appear when multiple packages are loaded together.
+
+Specifically, it:
+
+1. Instantiates `SqlColumnEncryptionAzureKeyVaultProvider` to force the AKV provider assembly and
+   all its transitive dependencies to load alongside SqlClient.
+2. Opens a `SqlConnection` using a connection string you provide, exercising the authentication
+   and network code paths end-to-end.
+
+The app is designed to run against both **published NuGet packages** and **locally-built packages**
+(via the `packages/` directory configured in `NuGet.config`).
+
+## How This Differs From the Existing Test Suite
+
+The SqlClient repository has a large suite of unit, functional, and manual tests.  This tool
+complements — but does not replace — those tests.  The key differences are:
+
+### Heterogeneous package versions
+
+The test projects reference sibling packages via project references or a shared `Directory.Packages.
+props` file.  Every test run uses a **single, uniform version set** derived from whatever is
+currently checked out.  You cannot ask the test suite to run `SqlClient 7.0.1` against
+`AkvProvider 7.1.0-preview1` without editing project files.
+
+This tool accepts any combination of independent version numbers — including versions that have not
+been published yet — at the command line:
+
+```bash
+dotnet run \
+  -p:SqlClientVersion=7.0.1 \
+  -p:AkvProviderVersion=7.1.0-preview1 \
+  -- -c "<connection string>"
+```
+
+This makes it straightforward to answer questions like *"does the new AKV provider build work
+against the last published SqlClient release?"* without modifying any source files.
+
+### Pre-release and locally-built packages
+
+Because NuGet resolves packages from the `packages/` local feed before falling back to NuGet.org,
+you can drop pre-release `.nupkg` files in that folder and reference them immediately — even before
+they have been published.  The existing tests have no equivalent mechanism; they can only reference
+packages that are either checked out as source or already published to a configured feed.
+
+### End-to-end runtime coverage across the full package graph
+
+The test suite exercises individual classes and APIs in isolation.  Functional and manual tests do
+open real connections, but they always run against the packages as built from source in the current
+branch.
+
+This tool loads every package in the dependency graph simultaneously in a single process and then
+opens a live `SqlConnection`.  This catches a class of failures that isolated tests miss:
+
+- **Binding redirect conflicts**: two packages pulling in incompatible versions of a shared
+  dependency (`Azure.Core`, `Microsoft.Identity.*`, etc.) that only manifest when all packages are
+  present in the same AppDomain.
+- **Transitive version mismatches**: a package expecting an internal API surface that has changed in
+  a sibling package across a version boundary.
+- **Registration side-effects**: authentication providers or other singleton registrations that
+  interfere when packages are composed in an unexpected order or version combination.
+
+### Diagnostic console output
+
+When a connection fails, the tool can emit structured TDS-level and authentication trace output via
+the `--log` and `--trace` flags.  This output is written directly to the console and requires no
+test harness or log configuration — useful for quickly diagnosing authentication failures in CI
+environments or on developer machines where full test infrastructure is unavailable.
+
+The test suite's diagnostics are routed through `EventSource`/`DiagnosticListener` and are only
+visible if a listener is attached (e.g. via `dotnet-trace` or a custom test initializer).
+
+### What this tool does NOT do
+
+- It does not assert on individual API behaviours, query results, or error messages.  For that, use
+  the existing unit and functional tests.
+- It cannot run without a real SQL Server instance.  The manual test suite has the same constraint
+  for connectivity tests, but unit and functional tests run without a server.
+- It does not cover every authentication mode automatically.  You must provide a suitable connection
+  string for each mode you want to validate.
+
+## Project Layout
+
+- `src/` contains the tool source files and project file.
+- `test/` is reserved for tests.
+
+## Authentication Modes
+
+The authentication mode embedded in the connection string controls which code paths and packages are
+exercised during the connectivity test.  Use different modes to broaden coverage:
+
+| Authentication mode | `Authentication=` value | Packages exercised |
+| --- | --- | --- |
+| SQL Server auth | *(omit or `SqlPassword`)* | `Microsoft.Data.SqlClient` only |
+| Entra ID — integrated | `ActiveDirectoryIntegrated` | `Microsoft.Data.SqlClient` + `Extensions.Azure` (requires `AzureVersion`) |
+| Entra ID — default chain | `ActiveDirectoryDefault` | `Microsoft.Data.SqlClient` + `Extensions.Azure` (requires `AzureVersion`) |
+| Entra ID — password | `ActiveDirectoryPassword` | `Microsoft.Data.SqlClient` + `Extensions.Azure` (requires `AzureVersion`) |
+| Entra ID — interactive | `ActiveDirectoryInteractive` | `Microsoft.Data.SqlClient` + `Extensions.Azure` (requires `AzureVersion`) |
+| Entra ID — service principal | `ActiveDirectoryServicePrincipal` | `Microsoft.Data.SqlClient` + `Extensions.Azure` (requires `AzureVersion`) |
+| Entra ID — managed identity | `ActiveDirectoryManagedIdentity` | `Microsoft.Data.SqlClient` + `Extensions.Azure` (requires `AzureVersion`) |
+
+> **Note:** All Entra ID modes require the `Extensions.Azure` package to be referenced (pass
+> `-p:AzureVersion=<version>`).  Without it, SqlClient will throw at runtime because no
+> authentication provider is registered for those modes.
+
+## Build Parameters
+
+Package versions are controlled through build properties. Pass them on the command line with `-p:`
+(or `/p:`) to override the defaults defined in `Directory.Packages.props`.
+
+| Property | Default | Description |
+| --- | --- | --- |
+| `AbstractionsVersion` | `1.0.0` | Version of `Microsoft.Data.SqlClient.Extensions.Abstractions` to reference. |
+| `AkvProviderVersion` | `7.0.0` | Version of `Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider` to reference. |
+| `AzureVersion` | None | Version of `Microsoft.Data.SqlClient.Extensions.Azure` to reference.  When omitted, the `Azure` package will not be referenced. |
+| `LoggingVersion` | `1.0.0` | Version of `Microsoft.Data.SqlClient.Internal.Logging` to reference. |
+| `SqlClientVersion` | `7.0.1` | Version of `Microsoft.Data.SqlClient` to reference. |
+| `SqlServerVersion` | `1.0.0` | Version of `Microsoft.SqlServer.Server` to reference. |
+
+## Local Package Source
+
+The `NuGet.config` adds a `packages/` directory as a local package source. To test against packages
+that haven't been published to NuGet yet, copy the `.nupkg` files into this folder and specify the
+matching version via the build properties above.
+
+NuGet will cache copies of the packages it finds in `packages/` after a successful restore.  If you
+update the `.nupkg` files in `packages/` without incrementing their version numbers (and referencing
+those new version numbers) you will have to clear the NuGet caches in order for the next restore
+operation to pick them up:
+
+```bash
+dotnet nuget locals all --clear
+```
+
+## Running the App
+
+The app has built-in help:
+
+```bash
+dotnet run -- --help
+
+Description:
+  Package Compatibility Tester
+  ----------------------------
+
+  Validates SqlClient connectivity using EntraID (formerly Azure Active Directory) authentication.
+  Connects to SQL Server using the supplied connection string, which must specify the authentication method.
+
+  ...
+```
+
+The app requires a connection string.  Use SQL authentication for a basic connectivity check:
+
+```bash
+dotnet run -- -c "Server=myserver;Database=mydb;User ID=sa;Password=<pw>;Encrypt=Mandatory;TrustServerCertificate=true"
+```
+
+To exercise Entra ID flows, include an `Authentication` keyword and reference the `Extensions.Azure`
+package:
+
+```bash
+dotnet run -p:AzureVersion=1.0.0 -- -c "Server=myserver.database.windows.net;Database=mydb;Authentication=ActiveDirectoryDefault"
+```
+
+On success the app emits to standard out:
+
+```bash
+Package Compatibility Tester
+----------------------------
+
+Packages used:
+  Abstractions:  1.0.1
+  AKV Provider:  7.0.0
+  Azure:         1.1.0-preview1
+  Logging:       1.0.1
+  SqlClient:     7.1.0.preview1
+  SqlServer:     1.0.0
+
+Connection details:
+  Data Source:      adotest.database.windows.net
+  Initial Catalog:  Northwind
+  Authentication:   ActiveDirectoryPassword
+
+Testing connectivity...
+Connected successfully!
+    Server version: 12.00.1017
+```
+
+Errors will be emitted to standard error:
+
+```bash
+Testing connectivity...
+Connection failed:
+  Cannot find an authentication provider for 'ActiveDirectoryPassword'.
+```
+
+### Examples
+
+Run a basic SQL authentication check using the default package versions:
+
+```bash
+dotnet run -- -c "Server=myserver;Database=mydb;User ID=sa;Password=<pw>;Encrypt=Mandatory;TrustServerCertificate=true"
+```
+
+Run with no `Azure` package — Entra ID modes will fail at runtime if specified in the connection
+string, which is itself useful for confirming the error path:
+
+```bash
+dotnet run -- -c "<connection string>"
+```
+
+Include the `Azure` package to enable Entra ID authentication flows:
+
+```bash
+dotnet run -p:AzureVersion=1.0.0-preview1 -- -c "<connection string>"
+```
+
+Run against locally-built packages (drop `.nupkg` files into `packages/` first):
+
+```bash
+dotnet run -p:SqlClientVersion=7.1.0-preview1 -- -c "<connection string>"
+```
+
+Override all five package versions at once:
+
+```bash
+dotnet run \
+  -p:AbstractionsVersion=1.0.1 \
+  -p:AkvProviderVersion=7.1.0-preview1 \
+  -p:AzureVersion=1.0.0 \
+  -p:LoggingVersion=1.0.1 \
+  -p:SqlClientVersion=7.1.0-preview1 \
+  -p:SqlServerVersion=1.0.0 \
+  -- -c "<connection string>"
+```
+
+## Prerequisites
+
+- [.NET 10.0 SDK](https://dotnet.microsoft.com/download) and .NET Framework 4.8.1 or later.
+- A SQL Server or Azure SQL instance reachable from the machine running the tool.
+- For Entra ID authentication modes: Azure credentials available to `DefaultAzureCredential`
+  (e.g. Azure CLI login, environment variables, or managed identity), and the `AzureVersion`
+  build property set so the `Extensions.Azure` package is included.

+# PackageValidator
+
+A standalone .NET 10 command-line tool that inspects one or more NuGet packages (`.nupkg`) and
+validates their **versions, signing, and symbols**.
+
+PackageValidator is a first-class maintainer tool for the SqlClient family of packages. It reads
+assemblies purely through **metadata** — it never loads them into the runtime — which makes it:
+
+- **Cross-platform.** It runs on any OS that hosts .NET 10.
+- **Framework-agnostic.** It can read assemblies built for target frameworks the host does not run
+  (for example, inspecting `net462` binaries from a Linux host).
+- **Side-effect free.** No module initializers or assembly-load events are ever
+  executed.
+
+It is designed to be run both interactively (to inspect a package) and in CI (to **gate** a build
+with `--fail-on` and assert expected versions with `--expect-*`).
+
+## What it checks
+
+For every package it opens, PackageValidator reports and validates:
+
+- **Package identity** — id, version, dependency groups, and NuGet signature, read from the embedded
+  `.nuspec`.
+- **Per-assembly versions** — `AssemblyVersion`, `FileVersion`, `InformationalVersion`, culture,
+  public key token, strong-name signing status, and target framework.
+- **Native binaries** — Win32 version-resource information and architecture.
+- **Binary classification** — implementation / reference / satellite / native, so symbol coverage is
+  judged only over implementation assemblies.
+- **Symbols** — sibling `.snupkg` matching by debug GUID with portable-PDB checksum verification,
+  embedded-symbol detection, and orphan/mismatch reporting.
+- **Intrinsic rules** — severity-tagged findings for missing/mismatched symbols,
+  unsigned/delay-signed assemblies, dependency inconsistencies, and more.
+- **Expected versions** — optional `--expect-*` assertions for inter-package version-match
+  validation.
+
+## Building and running
+
+The tool lives under `tools/PackageValidator` with its own `global.json` and `Directory.*.props`,
+isolated from the main driver build.
+
+```bash
+# From tools/PackageValidator/src
+dotnet run -- <paths>... [options]
+
+# Or build once and invoke the produced binary
+dotnet build -c Release
+./bin/Release/net10.0/PackageValidator <paths>... [options]
+```
+
+It is also wired into the repository's `build.proj`:
+
+- `BuildPackageValidator` / `BuildPackageValidatorTest` — build the tool and tests.
+- `TestPackageValidator` — run the test suite.
+- `BuildTools` — builds the tools and their test projects.
+
+## Usage
+
+```bash
+PackageValidator <paths>... [options]
+```
+
+| Argument / option | Description |
+| --- | --- |
+| `<paths>...` | One or more `.nupkg` files, or directories scanned recursively for `.nupkg` files. |
+| `--json` | Emit machine-readable JSON instead of the human-readable layout. |
+| `--no-snupkg` | Do not look for or process sibling `.snupkg` symbol packages (embedded symbols are still evaluated). |
+| `--fail-on <value>` | Exit non-zero when a finding matches the given value. Repeatable. |
+| `--expect-package-version [id=]VALUE` | Confirm the package version equals `VALUE`. Repeatable. |
+| `--expect-file-version [id=]VALUE` | Confirm every assembly's file version equals `VALUE`. Repeatable. |
+| `--expect-assembly-version [id=]VALUE` | Confirm every assembly's assembly version equals `VALUE`. Repeatable. |
+
+### `--fail-on` values
+
+`--fail-on` accepts a **severity** (`error`, `warning`, `info`), the token `any`,
+or one of the following finding **categories**:
+
+- `version-inconsistency`
+- `missing-symbols`
+- `symbol-mismatch`
+- `symbol-checksum-mismatch`
+- `symbol-orphan`
+- `symbol-duplicate`
+- `delay-signed`
+- `unsigned`
+- `package-unsigned`
+- `dependency-inconsistency`
+- `unexpected-package-version`
+- `unexpected-file-version`
+- `unexpected-assembly-version`
+
+### `--expect-*` values
+
+Each `--expect-*` value is either `VALUE` (applies to every package in the run) or `id=VALUE`
+(applies only to the package whose id is `id`). A specific id overrides a bare `VALUE` (wildcard),
+and because the options repeat, a family-wide expectation can coexist with a per-package override —
+for example, assert one family file version while letting `Microsoft.SqlServer.Server` differ.  A
+missing version counts as a mismatch, so an assertion never silently passes.
+
+### Exit codes
+
+| Code | Meaning |
+| --- | --- |
+| `0` | Success; no gating findings. |
+| `1` | Runtime/inspection error. |
+| `2` | A `--fail-on` gate was tripped. |
+
+(Argument-parsing errors return a non-zero `System.CommandLine` code.)
+
+The same reference details are printed in a free-form **Notes** section appended to `--help`.
+
+## Examples
+
+Inspect a single package (human-readable):
+
+```bash
+PackageValidator Microsoft.Data.SqlClient.7.1.0-preview1.nupkg
+```
+
+Emit JSON for tooling:
+
+```bash
+PackageValidator Microsoft.Data.SqlClient.7.1.0-preview1.nupkg --json
+```
+
+Gate a directory of packages against an expected family file version, with a per-package override,
+and fail on any error:
+
+```bash
+PackageValidator <dir-of-nupkgs> \
+  --expect-file-version *=7.1.0.17604 \
+  --expect-file-version Microsoft.SqlServer.Server=1.1.0.17604 \
+  --fail-on error
+```
+
+> **Symbol packages from nuget.org:** the flat-container feed only serves `.nupkg` files. To
+> exercise the `.snupkg` path, download the symbol package from the gallery's symbol endpoint
+> (`https://www.nuget.org/api/v2/symbolpackage/{Id}/{Version}`) and save it beside the `.nupkg` with
+> the same base name (for example `microsoft.data.sqlclient.5.2.2.snupkg`).

+### File responsibilities
+
+| File | Responsibility |
+| --- | --- |
+| `Program.cs` | Console entry point. Defines the `System.CommandLine` surface (arguments, options, and the `--help` Notes section), enumerates input paths, drives inspection and validation, selects the output renderer, and maps results to process exit codes. |
+| `PackageInspector.cs` | Opens a `.nupkg` (a zip archive), reads the `.nuspec` for id/version/dependencies, detects the `.signature.p7s` signature entry, inspects every `.dll` entry, and invokes the symbol resolver — producing a `PackageReport`. |
+| `AssemblyInspector.cs` | Inspects a single `.dll` archive entry via `PEReader`/`MetadataReader` without loading it. Extracts assembly name, versions, culture, public key token, strong-name status, target framework, and debug (CodeView) GUID/checksums. Falls back to native reporting for non-managed DLLs. |
+| `NativeVersionReader.cs` | Reads Win32 version-resource fields (file/product version, product name) and architecture from native binaries. Stages bytes to a temp file for `FileVersionInfo`, falling back to architecture-only when staging fails. |
+| `BinaryClassifier.cs` | Classifies a managed DLL's package path into a `BinaryKind` (implementation under `lib/` or `runtimes/<rid>/lib/`, reference under `ref/`, satellite `*.resources.dll`, or other). |
+| `SymbolResolver.cs` | Locates the sibling `.snupkg`, indexes its PDBs by debug GUID and path, matches each assembly (authoritative GUID match with checksum verification, or path-based mismatch detection), and reports orphaned/duplicate symbol files. Loads PDB bytes on demand to keep peak memory low. |
+| `PortablePdb.cs` | Low-level portable-PDB helpers: read the debug GUID, detect legacy Windows PDBs, and verify a PDB against an assembly's recorded checksum (locating the `#Pdb` stream and zeroing the PDB id before hashing). |
+| `VersionExpectations.cs` | Parses the `--expect-package/file/assembly-version` specs into per-id (and wildcard) expectations and resolves the applicable expected value for a given package, enabling inter-package version-match validation. |
+| `VersionRange.cs` | Evaluates whether a concrete version satisfies a NuGet dependency range, following SemVer 2.0 precedence (prerelease ordering; build metadata ignored). Used by dependency-consistency checks. |
+| `Validator.cs` | Defines the stable finding `Categories` and applies the intrinsic validation rules, producing per-package and cross-package `Finding` instances (symbols, signing, dependency and expected-version consistency). |
+| `HumanReporter.cs` | Renders a `ValidationRun` to standard output in the human-readable layout: per-package details and findings, cross-package findings, and the run summary. |
+| `Json.cs` | Source-generated `JsonSerializerContext` for trim/AOT-friendly, indented, camel-cased JSON output (nulls omitted, enums as strings). |
+| `Models.Common.cs` | Shared enums and value types used across the tool: `BinaryKind`, `SigningStatus`, `Severity`, `Finding`, `NativeVersionInfo`, `PdbChecksum`, and related value types. |
+| `Models.Report.cs` | The report DTO graph serialized to JSON and rendered as text: `ValidationRun`, `ValidationSummary`, `PackageReport`, `BinaryReport`, `SymbolPackageInfo`, and related types. |
+
+## Related public tools
+
+No single public tool combines everything PackageValidator does, but each area it covers has
+established, general-purpose analogs. This tool intentionally folds them into one dependency-light,
+cross-platform CLI tailored to the SqlClient package family.
+
+| Area | Public tools | Relationship |
+| --- | --- | --- |
+| Package inspection & health rules | [NuGet Package Explorer](https://github.com/NuGetPackageExplorer/NuGetPackageExplorer), [`dotnet validate`](https://github.com/meziantou/Meziantou.Framework) (Meziantou) | Closest all-round analogs: inspect `.nupkg` metadata, layout, symbols, and run package-hygiene rules. |
+| Package/assembly signatures | `dotnet nuget verify`, `signtool`, `sn.exe` | Verify NuGet, Authenticode, and strong-name signing state. PackageValidator reports the same strong-name/NuGet-signature state inline. |
+| API surface & compatibility | [`Microsoft.DotNet.ApiCompat`](https://github.com/dotnet/sdk), SDK `PackageValidation` (`<EnablePackageValidation>`), [`PublicApiAnalyzers`](https://github.com/dotnet/roslyn-analyzers) | Catch breaking API/TFM changes across versions — complementary to, not overlapping with, this tool's version checks. |
+| Assembly/metadata inspection | [ILSpy / `ilspycmd`](https://github.com/icsharpcode/ILSpy), `dotnet-ildasm`, [`AsmSpy`](https://github.com/mikehadlow/AsmSpy) | Metadata-only inspection (same `System.Reflection.Metadata` approach); AsmSpy specifically reports version conflicts across binaries. |
+| Symbols / Source Link | [`sourcelink`](https://github.com/dotnet/sourcelink), `Microsoft.SourceLink.*` | Verify portable-PDB checksums and Source Link — the same portable-PDB checksum verification this tool performs against the sibling `.snupkg`. |
+
+**What makes PackageValidator distinct:**
+
+- Metadata-only reading (like ILSpy) so it can inspect `net462` assemblies from a Linux host, with
+  no assembly loading.
+- Symbol matching by debug GUID **and** portable-PDB checksum (like sourcelink), including
+  orphan/mismatch detection against the sibling `.snupkg`.
+- Strong-name and NuGet signature state reported inline (like `sn` / `nuget verify`).
+- **Inter-package version-match assertions** (`--expect-*`) — asserting a whole *family* of packages
+  carries consistent versions, which the general-purpose tools above do not do out of the box.
+- CI gating via `--fail-on` severity/category selectors.
+
+## Tests
+
+The `test/` project is an xUnit v3 suite running on Microsoft.Testing.Platform.  It covers
+public-key-token computation, binary classification, SemVer 2.0 range evaluation (including
+prerelease ordering and malformed-input rejection), the rules engine, and expected-version
+assertions.

+in-flight async I/O during connection close in the **retired, in-box
+`System.Data.SqlClient`**. The environment reported in the ICM:
+
+| | Reported environment (ICM) |
+|---|---|
+| OS | Windows Server 2016 (10.0.14393) |
+| Runtime | .NET Framework 4.7 (CLR 4.0.30319) |
+| Driver | in-box `System.Data.dll` **4.7.4081.0** |
+| CPUs | 4 |
+
+`System.Data.SqlClient` is retired, so the fix (if any) is being investigated in
+`Microsoft.Data.SqlClient` via #43847. The branch adds regression tests on the
+MDS side; this harness points those same tests at the legacy driver.
+
+---
+
+## How it works
+
+Rather than re-implementing the tests, the project **links the real test source
+files** and swaps only the driver reference:
+
+- **Linked tests** (compiled verbatim, not copied):
+  - `SNICloseDeadlockTest.cs` (from `tests/UnitTests/SimulatedServerTests`) —
+    3 in-process tests: pending async read (via the in-repo TDS test server),
+    pre-login handshake, and TLS handshake (both via raw `TcpListener`).
+  - `SNICloseRaceDeadlockTest.cs` (same folder) — releases the server response
+    at the same instant as close so the read completion races `SNIClose`
+    (×100 iterations).
+  - `MarsCloseDeadlockTest.cs` (from `tests/ManualTests/SQL/AsyncTest`) —
+    live-server MARS pending-read test.
+  - `MarsCloseStressTest.cs` (same folder) — many MARS connections with
+    in-flight reads, all closed simultaneously over several iterations
+    (live server).
+- **Compat shim** makes the legacy driver satisfy the linked files' bare
+  `Microsoft.Data.SqlClient` type names:
+  - `GlobalUsings.cs` — global `using` aliases mapping `SqlConnection`,
+    `SqlCommand`, `SqlDataReader` to `System.Data.SqlClient`, and
+    `SqlConnectionStringBuilder` / `SqlConnectionEncryptOption` to the shims.
+  - `Compat.cs` — a `SqlConnectionEncryptOption` enum stand-in, a
+    `SqlConnectionStringBuilder` facade over the (sealed) legacy builder that
+    accepts the enum-typed `Encrypt`, and a `DataTestUtility` stand-in that
+    reads the connection string from `SNICLOSE_CONNSTR`.
+
+All four test files are the **real driver tests**; this project only links them
+and swaps the driver reference. (The race/stress tests were originally prototyped
+here and have since been promoted into the driver test projects.)
+
+The bare-name binding trick: the linked files sit in `Microsoft.Data.SqlClient.*`
+namespaces, and because this project does **not** reference MDS, unqualified
+names like `SqlConnection` fall through to the global aliases in `GlobalUsings.cs`.
+
+### Why `xunit.runner.json` (shadowCopy: false) matters
+
+`Microsoft.DotNet.XUnitExtensions` (which provides `[ConditionalTheory]`) ships a
+**delay-signed** beta assembly. On .NET Framework, xUnit's default shadow copy
+re-verifies the strong name from the shadow-copy directory and fails with
+`FileLoadException: strong name could not be verified`. The real test projects
+ship `xunit.runner.json` with `shadowCopy: false`; this harness **links that same
+file** so the delay-signed assembly loads from its build-output location (where
+.NET Framework's strong-name bypass applies).
+
+---
+
+## Target frameworks
+
+`net462;net47;net472;net481;net10.0`
+
+- **.NET Framework targets** use the **in-box** `System.Data.dll`.
+- **.NET (Core) target** (`net10.0`) uses the **`System.Data.SqlClient` NuGet
+  package** (version parametrized — see below).
+
+> **Important:** the in-box `System.Data.dll` is *machine-global* for the whole
+> 4.x line — only one physical DLL exists per machine. On this dev box that is
+> 4.8.1, so every netfx target binds 4.8.1 at runtime; the older TFMs only change
+> compile-time references and framework "quirk" behaviors, **not** the DLL bits.
+> To run the exact reported 4.7.4081.0 bits you need an environment isolated to
+> .NET 4.7.2 (see [Testing older in-box DLLs](#testing-older-in-box-dlls-containers)).
+
+---
+
+## Running
+
+From the repo root.
+
+### In-process tests only (no SQL Server)
+
+```powershell
+dotnet test .\tools\SniCloseLegacyRepro
+# or a single framework:
+dotnet test .\tools\SniCloseLegacyRepro -f net481
+```
+
+The live MARS test and the MARS stress test are skipped when no connection
+string is set.
+
+### With a live SQL Server (enables MARS + stress tests)
+
+Set `SNICLOSE_CONNSTR` yourself so the password is not routed through tooling:
+
+```powershell
+$env:SNICLOSE_CONNSTR = "Server=127.0.0.1,1434;Database=master;User ID=<user>;Password=<pwd>;TrustServerCertificate=true;Connect Timeout=15"
+dotnet test .\tools\SniCloseLegacyRepro -f net481
+Remove-Item Env:\SNICLOSE_CONNSTR   # clear when done
+```
+
+### Sweeping legacy NuGet versions (net10.0 only)
+
+The `.NET (Core)` target's package version is parametrized via
+`$(SqlClientLegacyVersion)` (default `4.9.1`). The versions must exist on a
+restore feed.
+
+```powershell
+foreach ($v in '4.5.3','4.6.1','4.7.0','4.8.6','4.9.1') {
+  dotnet test .\tools\SniCloseLegacyRepro -f net10.0 -p:SqlClientLegacyVersion=$v
+}
+```
+
+### Emulating the reported 4-CPU box
+
+Pin the test process (and its child `testhost`) to 4 cores:
+
+```powershell
+$p = Start-Process dotnet -ArgumentList 'test','.\tools\SniCloseLegacyRepro','-f','net47','--no-build' -PassThru -NoNewWindow
+$p.ProcessorAffinity = [IntPtr]0xF   # cores 0-3
+$p.WaitForExit()
+```
+
+---
+
+## Testing older in-box DLLs (containers)
+
+Because the in-box `System.Data.dll` is machine-global, the faithful way to test
+older bits is an isolated environment. Use the official .NET Framework images —
+the **framework version tag controls `System.Data.dll`**; the **Windows base tag
+controls the OS + native `sni.dll`**.
+
+```
+mcr.microsoft.com/dotnet/framework/runtime:<fwver>-windowsservercore-<base>
+```
+
+| Image tag | `System.Data.dll` ≈ | Role |
+|---|---|---|
+| `4.6.2-windowsservercore-ltsc2016` | 4.7.4081.0 (see note) | — |
+| `4.7-windowsservercore-ltsc2016` | **4.7.4081.0** | **ICM match** |
+| `4.7.2-windowsservercore-ltsc2016` | 4.7.4081.0 | ICM match |
+| `4.8-windowsservercore-ltsc2019` | 4.8.4690.0 | newer |
+| `4.8.1-windowsservercore-ltsc2022` | 4.8.9xxx | this dev box |
+
+> **.NET Framework 4.x is a single, in-place, monotonic runtime.** The `ltsc2016`
+> base OS is already serviced to 4.7.2, so its in-box `System.Data.dll` is
+> **4.7.4081.0** — and a lower framework tag (e.g. `4.6.2`) cannot downgrade it.
+> On this base, every tag at or below 4.7.2 resolves to the same 4.7.4081.0 DLL,
+> which happens to be the reported version (the practical floor). Getting
+> a genuinely older DLL (e.g. 4.6.x) would require an *unserviced* older base OS
+> image, which MCR does not publish.
+
+Verify the DLL version inside a container:
+
+```powershell
+(Get-Item C:\Windows\Microsoft.NET\Framework64\v4.0.30319\System.Data.dll).VersionInfo.FileVersion
+```
+
+### `run-in-container.ps1`
+
+The framework `runtime` images have **no `dotnet` CLI**, so `dotnet test` will not
+work there. The `run-in-container.ps1` helper handles this: it builds `-f net47`
+on the host, stages `xunit.console.exe` (from `xunit.runner.console`) next to the
+build output, and runs the tests in the container so they bind the container's
+old in-box `System.Data.dll`.
+
+```powershell
+# in-process tests only (no SQL Server):
+.\run-in-container.ps1
+
+# faithful ICM match: 4.7.4081.0 + 4 processors, live MARS + stress:
+$env:SNICLOSE_CONNSTR = "Server=127.0.0.1,1434;Database=master;User ID=sa;Password=***;TrustServerCertificate=true"
+.\run-in-container.ps1 -Cpus 4
+
+# a different framework image:
+.\run-in-container.ps1 -Image mcr.microsoft.com/dotnet/framework/runtime:4.8-windowsservercore-ltsc2019
+```
+
+**Networking:** a Windows container cannot reach the host's loopback, and
+`host.docker.internal` is not injected for hyperv-isolated Windows containers.
+The script targets the Docker NAT gateway (the host's `vEthernet (nat)` IP, e.g.
+`172.17.224.1`) and rewrites the connection string to it. Because the SQL Server
+(a Linux container published to host loopback) does not listen on that IP, add a
+one-time **elevated** host bridge:
+
+```powershell
+netsh interface portproxy add v4tov4 listenaddress=172.17.224.1 listenport=1434 connectaddress=127.0.0.1 connectport=1434
+New-NetFirewallRule -DisplayName "SQL 1434 from Windows containers" -Direction Inbound -LocalAddress 172.17.224.1 -LocalPort 1434 -Protocol TCP -Action Allow
+# teardown:
+#   netsh interface portproxy delete v4tov4 listenaddress=172.17.224.1 listenport=1434
+#   Remove-NetFirewallRule -DisplayName "SQL 1434 from Windows containers"
+```
+
+---
+
+## Findings
+
+Across every configuration tested, the deadlock **does not reproduce** (all
+tests pass), including:
+
+- in-box `System.Data.dll` 4.8.1 on `net462` / `net47` / `net472` / `net481`
+  (host dev box)
+- 4-CPU-pinned runs
+- the completion-races-close and MARS concurrency stress variants
+- the full `System.Data.SqlClient` NuGet lineage on `net10.0`
+  (4.5.3, 4.6.1, 4.7.0, 4.8.6, 4.9.1)
+- **the reported (ICM) environment**, reproduced faithfully in a container:
+  Windows Server 2016 base (`ltsc2016`) · .NET Framework 4.7 · in-box
+  `System.Data.dll` **4.7.4081.0** · **4 processors** (`--cpu-count 4`) · live
+  MARS + concurrency stress against SQL Server 2025 → **12/12 pass**.
+- container `ltsc2019` · .NET Framework 4.8 · `System.Data.dll` 4.8.4690.0 ·
+  4 processors · live MARS + stress → **12/12 pass**.
+
+So the SNIClose close-during-I/O deadlock does not reproduce even in a
+bit-for-bit reconstruction of the reported ICM environment. Because that
+*exact* `System.Data.dll` (4.7.4081.0) also passes, there is no
+version boundary / "fixed in a later servicing build" explanation: the synthetic
+tests simply do not trigger whatever the original incident hit. That points away
+from a plain client-side ordering bug reachable from managed timing alone, and
+toward something more environment-specific in the original incident (e.g. exact
+network/timing conditions, or a native-layer interaction not exercised here).
+
+### Additional reproduction attempts (`ReproAttempts.cs`)
+
+Harness-only, exploratory variants targeting conditions the shared tests do not
+create. On the exact 4.7.4081.0 bits at 4 CPUs, **none reproduces the issue**:
+
+- **Close under thread-pool starvation** → no deadlock.
+- **Sync-over-async on a single-threaded `SynchronizationContext`** (classic
+  ASP.NET shape) → no captured-context deadlock.
+- **Cancel `OpenAsync` during the TLS handshake** (internal abort/close path)
+  → settles promptly, no deadlock.
+- **`Open()` under client thread-pool starvation** (real, out-of-process server;
+  plain and TLS) → **`Open()` succeeds**. Starvation is *not* the reproduction.
+
+> A note on a false lead: an *in-process* TDS test server shares the client's
+> thread pool, so saturating the pool starves the **server** and makes `Open()`
+> time out - a test artifact. Against a real out-of-process server the driver's
+> `Open()` is robust under the same starvation, so the timeout does not indicate
+> a driver defect.
+
+---
+
+## Isolation notes
+
+- Uses Central Package Management via its own `Directory.Build.props`
+  (`ManagePackageVersionsCentrally=true`) and `Directory.Packages.props`, which
+  imports the shared SqlClient tests package versions. The legacy
+  `System.Data.SqlClient` package is pinned there; the net10.0 target overrides
+  it per-run via `VersionOverride` / `-p:SqlClientLegacyVersion=…`.
+- Legacy `System.Data.SqlClient` versions are served from the repo's governed
+  feed (no extra `NuGet.config`).
+- References the driver-agnostic in-repo TDS test-server projects
+  (`tests/tools/TDS/*`).

+// Tier-2 reproduction ATTEMPTS for ICM 775308542 / ADO.Net #43847 (harness-only,
+// exploratory - not promoted to the driver test suite unless one reproduces).
+//
+// The shared SNIClose/MARS tests conclusively show that a single connection
+// closed while one async I/O is in flight does NOT deadlock, even on the
+// customer's exact in-box System.Data.dll (4.7.4081.0) at 4 CPUs. These variants
+// target conditions those tests do not create, which better match the reported
+// symptom ("initial TLS handshake failure" under a 4-proc production load):
+//
+//   1. ThreadPoolStarvation  - the worker pool is saturated (as on a small,
+//      busy box) when the connection is closed, so an async completion callback
+//      cannot obtain a thread while the close path runs.
+//   2. SyncOverAsyncContext  - a single-threaded SynchronizationContext (as in
+//      classic ASP.NET) is blocked on an async SqlClient operation via .Result;
+//      if the driver captures the context for a continuation, it deadlocks.
+//   3. CancelOpenDuringTls   - OpenAsync is cancelled while the TLS handshake
+//      read is in flight, driving the driver's INTERNAL abort/close path
+//      (rather than an external Close on another thread). PROMOTED to the driver
+//      test suite as SNICloseHandshakeCancellationTest (linked in via the
+//      harness csproj), so it also runs against the legacy driver here.
+//   4. OpenUnderStarvation   - does client thread-pool starvation cause a
+//      connection/handshake failure? Against a REAL server it does NOT: the
+//      driver's Open() is robust. (An in-process test server shares the pool
+//      and would be co-starved - a test artifact, not driver behavior.)
+//
+// After the ICM dump was obtained, the real mechanism was identified: a
+// RE-ENTRANT SNIClose (Close() called synchronously from within
+// ReadAsyncCallback via the command-timeout -> failed-attention-write path, so
+// SNIClose spins in WaitForActiveCallbacks waiting for the callback it runs in).
+// Two further attempts target that mechanism:
+//
+//   5. CallbackReentrancy    - async read + short command timeout + a proxy that
+//      breaks the client's write. A regression guard for the MDS asyncClose fix;
+//      does not deterministically force the legacy re-entrancy (see its notes).
+//   6. ReentrantSNICloseSoak - many concurrent workers RST connections at ~the
+//      command-timeout instant, hunting the race probabilistically. OPT-IN
+//      (set SNICLOSE_SOAK_ENABLE) because it is heavy and, when it fires, poisons
+//      the process. It fired ONCE in a full-suite run on the legacy in-box driver
+//      (net462/47x/48x) but NOT on the Core NuGet lineage (net10.0) - a clean
+//      driver-lineage split consistent with the real bug - yet it did not recur
+//      in subsequent runs. So it confirms the mechanism is reachable but is not a
+//      reliable reproduction (matching the SQL EE's "very difficult to capture").
+//      The definitive evidence remains the dump + the asyncClose code review.
+//
+// All waits are bounded, so a genuine deadlock is reported as a failed
+// bounded-wait rather than hanging the run.

+    Diagnostic xUnit harness that runs SNIClose / MARS close-during-IO deadlock tests against the
+    LEGACY System.Data.SqlClient driver, to observe whether the deadlock (ICM 775308542 / ADO.Net
+    #43847) reproduces there.
+
+      * net462/net47/net472/net481 -> in-box System.Data.SqlClient (System.Data.dll)
+      * net10.0                     -> System.Data.SqlClient NuGet package
+
+    Rather than re-implementing the tests, this project LINKS the real test source files directly
+    (see the <Compile Include Link=...> items below) and supplies a small compatibility shim
+    (Compat.cs + GlobalUsings.cs) so the bare Microsoft.Data.SqlClient type names in those files
+    bind to the legacy driver.  See README.md for full usage, including running inside .NET
+    Framework Windows containers to bind older in-box System.Data.dll versions.
+
+    Run: dotnet test tools/SniCloseLegacyRepro                        (in-process tests only)
+      $env:SNICLOSE_CONNSTR="Server=<server>;User ID=<user>;Password=<pwd>"  (enables live MARS + stress)
+      dotnet test tools/SniCloseLegacyRepro
+
+    This project uses Central Package Management via the sibling
+    Directory.Packages.props (which imports the shared SqlClient tests versions) and
+    Directory.Build.props. The legacy System.Data.SqlClient package versions are served from the
+    repo's governed feed, so no extra NuGet.config is needed.

+         machine (here 4.8.1). Multi-targeting older netfx TFMs changes the
