System.Management.WbemDefPath doesn't work with trimming

[Symbai]

Description

NativeAOT (the trimming?) breaks the body of System.Management.WbemDefPath..ctor():

 ---> System.InvalidProgramException: Common Language Runtime detected an invalid program. The body of method 'Void System.Management.WbemDefPath..ctor()' is invalid.
   at Internal.Runtime.TypeLoaderExceptionHelper.CreateInvalidProgramException(ExceptionStringID, String) + 0x40
   at Internal.Runtime.CompilerHelpers.ThrowHelpers.ThrowInvalidProgramExceptionWithArgument(ExceptionStringID, String) + 0x9
   at System.Management.WbemDefPath..ctor() + 0x15

I'm reporting this here since NativeAOT will be moved into this repo anyway and it's probably a trimming issue? in which case it belongs to this repo.

Reproduction Steps

In nativeAOT project:

ManagementClass managementClass = new ManagementClass("Win32_BaseBoard");
var instances = managementClass.GetInstances();
foreach (var obj in instances)
{
    //...
}

In C# project call the export function of the nativeAOT project which executes the code above.

Expected behavior

No exception

Actual behavior

Other information

It's a windows x64 DLL project publishing using /p:NativeLib=Shared, I'm using NativeAOT compiler nuget version 6.0.0-*

NativeAOT compiler 6.0.0-* is out-of-date and missing plenty of fixes, can you try again with 7.0.0-*?

WbemDefPath is built-in COM. This doesn't work with trimming in general and NativeAOT implies trimming. It will have to be converted to ComWrappers.

Unfortunately not, see dotnet/runtimelab#1748

If anyone is looking to pick this up and needs an example of how to convert to COMWrappers, here are the PRs that converted System.Drawing.Common to use COMWrappers. They may be useful to get started on how to do it.

#54636
#54884

Also, check out the docs here: https://docs.microsoft.com/en-us/dotnet/standard/native-interop/tutorial-comwrappers

are there any workarounds on how to make system.management to work with nativeaot for now?

[MichalStrehovsky]

It's the same problem as #78038 that was recently closed but had a couple other people. System.Management needs to be converted to ComWrappers. It's starting to be a pretty popular request. Cc @jkoritzinsky if this is something that could be addressed with the COM source generator for .NET 8.

i managed to workaround using powershell.exe with Get-WmiObject command but indeed being able to do more advanced querying and not needing to parse the text output manually is preferred.

@ivanjx You can try WmiLight, It works for me.
