Details
- in Version 7.2.0.6702-preview2 it works
- Version 8.2.0.7535 is last released version where it works
- ILSpy shows in front of assmebly name a bluish icon
- the text of the exception comes from
System.Reflection.Metadata.dll, I replaced with newest, but still failing - source of exception is probably https://github.com/dotnet/runtime/blob/dde00d376e4b40674488c5c688899d7a343f4eca/src/libraries/System.Reflection.Metadata/src/System/Reflection/Metadata/MetadataReader.cs#L186
