Example of Security Interoperability in WCF Services

WCF supports several standard security mechanisms, following the various security-related WS-* standards. For example, you may need to specify transport-level security when you communicate with an older Java Web service. In this case, encryption is necessary because the Username token, including the user’s password, is passed with the message.

Exposing multiple contracts is useful because it means that you can release a new version of a contract, but still support legacy client applications that may continue to use the old contract.
