Repro
There is a problem when calling explicitly implemented interface methods
through remoting. For example we have an interface IRemoteObject shared between
the server and client. The server registers a typed implementing this interface
explicitly. When the client attempts to call any methods on this interface, the
client throws the following exception:
Unhandled Exception: System.Runtime.Remoting.RemotingException: Tcp transport
error.
Server stack trace:

and the server does not receive the method call.
Implementing the method implicitly does not cause the same problem.
I have attached a example application demonstrating working and broken
behaviours. Running the same code under Windows and the Microsoft CLR this does
not happen and the method call executes without error in both cases.
