PInvoke.CoRegisterClassObject not working in a NativeAOT, PackagedCom, ExeServer situation

[catmanjan]

I am calling PInvoke.CoRegisterClassObject for COM interop purposes.

My classes were never instantiated by the caller, so I tried defining my own import and it worked:

[LibraryImport("OLE32")]
[PreserveSig]
private static partial int CoRegisterClassObject(in Guid rclsid, nint pUnk, uint dwClsContext, uint flags, out uint lpdwRegister);

Is there some way I can instruct cswin32 to generate it in this working format? I'm not exactly sure what it is that is not making it work

Here is the calling code:

var thumbnailProviderFactory = new ThumbnailProviderFactory(client);
var thumbnailProviderFactoryInterface = ComWrapper.GetOrCreateComInterfaceForObject(thumbnailProviderFactory, CreateComInterfaceFlags.None);
CoRegisterClassObject(typeof(ThumbnailProvider).GUID, thumbnailProviderFactoryInterface, (uint)CLSCTX.CLSCTX_LOCAL_SERVER, (uint)REGCLS.REGCLS_MULTIPLEUSE, out var thumbnailProviderFactoryCookie);

csproj contains

	  <CsWin32RunAsBuildTask>true</CsWin32RunAsBuildTask>
	  <DisableRuntimeMarshalling>true</DisableRuntimeMarshalling>
