Source code and NAnt build file for repro

I have a sample application (see attachment) consisting of a server, client and
a shared component. I declare an interface in the shared component. The server
defines class implementing this interface and the client tries to get an
instance of the remoted object through the interface.

This results in the following exception being thrown in the client:

System.Runtime.Remoting.RemotingException: Cannot cast from client type
'Trac79.Shared.IRemoteObject, Shared, Version=0.0.0.0, Culture=neutral,
PublicKeyToken=null' to server type 'Trac79.Server.RemoteObject'

Remoting an interface like this is supported by the CLR and does not result in
this exception.
