Service contract

A client is unable to connect to a service on anything other than the exact URI used for instantiation.

E.g., if the server is instantiated with an endpoint URI of "http://localhost:8080" , and the client is instantiated with an endpoint URI of "http://127.0.0.1:8080", the result of trying to connect is:

On MS.NET, if I instantiate the server with localhost, or "0.0.0.0", I'm able to successfuly connect to any of the machine's IPs (127.0.0.1, 10.0.0.50, external.hostname, etc.)

Attached are some minimal classes that Just Work on MS.NET, and result in the aforementioned exception on Mono+Olive.
