cannot serialize internal class? about messagepack-csharp

[asyncx]

I don't know if this has been mentioned but you can workaround if you add the following lines to your project

[assembly: InternalsVisibleTo("MessagePack")]
[assembly: InternalsVisibleTo("MessagePack.Resolvers.DynamicObjectResolver")]
[assembly: InternalsVisibleTo("MessagePack.Resolvers.DynamicUnionResolver")]

This way MessagePack.Resolvers.DynamicObjectResolver will be able to access your internal types and avoid the "attempting to implement an inaccessible interface" error.

Yes.
This is assembly builder limitation.
https://msdn.microsoft.com/en-us/library/system.reflection.emit.assemblybuilder(v=vs.110).aspx

MessagePack for C# create assembly per resolver and create dynamic formatter per resolver.

var t = DynamicObjectResolver.Instance.GetFormatter<TestObject>();

// MessagePack.Formatters.TestObjectFormatter
Console.WriteLine(t.GetType().FullName);

// MessagePack.Resolvers.DynamicObjectResolver, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
Console.WriteLine(t.GetType().Assembly.FullName);

Created assembly is same as standard assembly so can not access external internal type.

Note: But I should output more informational exception message.

Thank you for response,I understand.
I think it's better adding this limitation in README, how about it?

[neuecc]

Thank you, I've added it.
and I'll add varidate and throw informational exception.

Should I close this issue, or leave for fix?
