Can not use protobuf-net with ILRepack

[dimsa]

I try to merge libraries into one file using ILRepack

ILRepack.exe /union /out:repack.dll"ProbufRepack.dll" "System.Collections.Immutable.dll" "protobuf-net.Core.dll" "protobuf-net.dll"

And get the following error:

Mono.Cecil.ResolutionException: Failed to resolve System.Diagnostics.CodeAnalysis.DynamicallyAccessedMemberTypes
   at Mono.Cecil.Mixin.CheckedResolve(TypeReference self)
   at Mono.Cecil.MetadataBuilder.GetConstantType(TypeReference constant_type, Object constant)

   at Mono.Cecil.ModuleDefinition.Write(String fileName, WriterParameters parameters)
   at ILRepacking.ILRepack.Repack()
   at ILRepacking.Application.Main(String[] args)

Please find attached simple project to reproduce it. ILRepack and all libraries can be found in bin/Release/net6.0 Protobuf and ILRepack have last versions.

ProbufRepack.zip

I also tried to download sources of Probuf-net.Core, I've found this types, but was not able to change this behavior.

Please also check the protobuf sources: https://github.com/protobuf-net/protobuf-net/blob/main/src/protobuf-net.Core/Internal/DynamicallyAccessedMembersAttribute.cs. Protobuf hasn't nuget dependency with these types.

Thank you in advance.

Confirmed that 2.0.23 is broken, but latest master is fixed. We will publish 2.0.24 soon and it should be fixed there.
