IQueryable Interface Implementation for Windows Management Instrumentation.

Projects descriptions

VNetDev.WmiQueryableCore

The project represents main WMI Queryable library that provides base WMI context object, attributes, exception classes and interfaces.

https://www.nuget.org/packages/VNetDev.WmiQueryableCore/

VNetDev.WmiQueryableCore.WqlTranslator

The projects provide WMI translation functionality.

https://www.nuget.org/packages/VNetDev.WmiQueryableCore.WqlTranslator/

VNetDev.WmiQueryableCore.WqlTranslator.Abstraction

This project contains a set of interfaces represent WqlTranslator object and its elements.

https://www.nuget.org/packages/VNetDev.WmiQueryableCore.WqlTranslator.Abstraction/

VNetDev.WmiQueryableCore.Cim

The WMI Queryable driver provides communication over WinRM protocol.

https://www.nuget.org/packages/VNetDev.WmiQueryableCore.Cim/

VNetDev.WmiQueryableCore.DCom

The WMI Queryable driver provides communication over DCom.

https://www.nuget.org/packages/VNetDev.WmiQueryableCore.DCom/

VNetDev.WmiQueryableCore.CIMv2

The project that extends Base WMI context class by implementing all the classes provided in Windows default WMI namespace "root\CIMV2".

https://www.nuget.org/packages/VNetDev.WmiQueryableCore.CIMv2/

VNetDev.WmiQueryableCore.Sms

The project that extends Base WMI context class by implementing all the classes provided in Microsoft Endpoint Configuration Manager version 2002.

https://www.nuget.org/packages/VNetDev.WmiQueryableCore.Sms/

Code Examples

Connecting to WMI (Locally with current credentials via DCom)

 var context = new CIMv2WmiContext();
 context.Configure(x => x.UseDCom());

Connecting to WMI (Locally with current credentials via WinRM)

 var context = new CIMv2WmiContext();
 context.Configure(x => x.UseCim());

Connecting to WMI (Remotely with provided credentials)

 var context = new CIMv2WmiContext();
 context.Configure(x => x.UseCim(
     "RemoteComputerNameOrIp", "root\\CIMV2",
     PasswordAuthenticationMechanism.Default,
     "domain.local", "AdminUserName", "Password123"));

Adding WmiContext to dependency injection container

 services.AddWmiContext<WmiContext>(options 
     => options.UseCim());

Simple processes query and termination

 foreach (var process in context.Win32Process
     .Where(p => p.Name.StartsWith("calc")))
 {
     Console.WriteLine($"Found '{process.Name}' process[{process.ProcessId}]! Terminating...");
     process.Terminate();
 }

Query all devices that have issues

 foreach (var entity in context.Win32PnPEntity
     .Where(e => e.ConfigManagerErrorCode != 0))
 {
     Console.WriteLine($"Device {entity.Name} has an issue.");
 }

New process creation (using static method)

 Win32Process.Create(context, "calc.exe");

Custom class and custom Context

Class

 [WmiClass(Name = "Win32_Process")]
 public class Win32CustomProcess
 {
     [WmiProperty(Name = "ProcessID")]
     public uint Pid { get; set; }
     public string Name { get; set; }
 }

Context

 public class CustomWmiContext : WmiContext
 {
     public WmiClassSet<Win32CustomProcess> Processes { get; set; }

     public CustomWmiContext()
     {
     }
     public CustomWmiContext(WmiContextOptions options) : base(options)
     {
     }
 }
