Calling .NET 4.x hosted service from .NET core client serialization fails

[adospace]

Describe the bug
Seems that calling a full .net hosted service from a .net core client can't work with a serialization exception

To Reproduce

1. Create a full .net hosted service using named pipes (but I believe same occurs with a tcp channel)
2. Create a .net core (tested 3.1) client using named pipes
3. Running the client an exception occurs:

JKang.IpcServiceFramework.IpcFaultException: Failed to deserialize request. ---> JKang.IpcServiceFramework.IpcSerializationException: Failed to deserialize IPC message ---> Newtonsoft.Json.JsonSerializationException: Error converting value "System.Int32, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e" to type 'System.Type'.

Expected behavior
The call should just work

This is the definition of the service:

    public class HostRectangle
    {
        public int Left { get; set; }
        public int Top { get; set; }
        public int Width { get; set; }
        public int Height { get; set; }
    }

    public class ConnectionSettings
    {
        public string Server { get; set; }

        public string Username { get; set; }

        public string Password { get; set; }

        public string Domain { get; set; }
    }

    public interface IRdpHost
    {
        void Create(int parentHandle, HostRectangle hostRect, ConnectionSettings connectionSettings);

        void ResizeWindow(HostRectangle hostRect);

        void CloseHost();
    }

I don't know if this is expected behavior?

@adospace I think this is as expected because assembly names are different between .NET 4 and .NET core (mscorlib vs. System.Private.CoreLib). Maybe you can implement a customized IIpcMessageSerializer to resolve the problem.

#167 should resolve the issue. I'm closing for now and feel free to reopen if necessary.
