Create PCL/Silverlight version of MsgPackServiceClient
The MessagePack format seems pretty ideal for communication between a ServiceStack service and a Silverlight client. Unfortunately there is no PCL package for ServiceStack.MsgPack.
On top of that it would be useful to split the client and server parts into separate packages.
Silverlight/PCL is dead but ServiceStack.MsgPack supports both .NET v4.5 and .NET Standard 2.0 which supports most active .NET platforms.
