If both client and server will be running .NET, you'll probably get
better performance (and less problems) using remoting. The
serialization will done for you by the remoting framework. Your code
can be as simple as:

MyServerObject server = new MyServerObject();
server.Method1();
server.Method3(4, 3);

Yet "MyServerObject" is an object on a remote server.
