Hi. Currently NativeAOT lacking of support for Com servers. The link https://learn.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.comwrappers.getorcreateobjectforcominstance?view=net-8.0 which you gave to me in email, does not the help with createion of COM server.

If you brave enough, you can create DLL where you export nescessary functions 'DllGetClassObject' at minimum and implement IClassFactory you can do the trick.

You can see how it was done in managed profiler.

Be careful, since all marshalling between COM datatypes and .NET datatypes you have to do yourself.
