C# msgpack RPC server compatible library

[danyhm]

Hello,

thanks for the great work. I ran both the client and the server examples successfully.

however, I need many more features for my server-side so I can't use c++ on my server. I need c# .net core.
on the other hand, I couldn't find any compatible library for .net that supports msgpack RPC

my client is c++ and my server is C# .net core

any recommendation?
