Repro steps
Compiling with these two classes will produce the bug.
public class ClassA<T> where T : ClassA<T>.ClassB
{
public class ClassB
{
}
}
Expected behavior
Compiles without error. I do not want to serialize these types with MessagePack. They are simply part of my game's code.
Environment Used
- MessagePack version: 3.1.2
- Unity 6000.0.33f1
- Scripting Backend: Mono
- API Compatiblity Level: .NET Standard 2.1
- Fresh project with no user code, except for the code mentioned above.
