Vista - WCF: Sending one type and receiving another

Hi,

I was wondering whether following scenario is possible. Say i have
contract defined with the base type
[ServiceContract]
public partial interface IMyInt
{
[OperationContract]
void SomeMethod(BaseType param);
}

On server side I have following class:
public class ServerType : Base Type {}
And on the client side:
public class ClientType : Base Type {}

I would like to send ClientType and have it demarshalled on server
side as ServerType. Is it possible?
