A domain service implementing this interface will be used to populate the user on both the client and server. The WebAuthenticationService class works with the generated DomainContext for any domain service implementing this interface.

The UpdateUser method is designed as an update method, and is invoked by calling the SubmitChanges method on the client. This implementation has an important point to consider when developing your application. When you invoke the UpdateUser method by calling SaveUser, you submit all changes that have occurred in the DomainContext and may therefore invoke other update methods. Conversely, when you invoke other update methods on the DomainContext, you submit all changes in the domain context and may invoke the UpdateUser method.
