[WCF RIA Services Version 1 Service Pack 2 is compatible with either .NET framework 4 or .NET Framework 4.5, and with either Silverlight 4 or Silverlight 5.]

Provides an abstract extension of the AuthenticationService that interacts with a DomainContext generated from a domain service implementing IAuthentication<T>.
