Hi,
On my project i have installed the latest versions of all packages and use a strongly type Hub declared in this way:

public class HubSync : Hub<ISendHubSync>

on ISendSync.cs i have declared the class that inherit from a base class in this way:

public interface ISendHubSync : ISendHubSyncBase
{
    void AddMessage(string name, string message);
    void SendHelloObject(HelloModel hello);
}
public interface ISendHubSyncBase
{
    void Heartbeat();
}

If i compile and run all works fine until i try to invoke the AddMessage from that client.
When i do that i get a TypeLoadException.

If i move the definition of HeartBeat() from the base class to the inherited class all works fine in any case.

What has been wrong ??
