What is Windows Communication Foundation (WCF)?

Windows Communication Foundation (WCF), which is part of the .NET Framework(Included in versions 3.0 and 3.5), is a platform where developers can build service-oriented applications. WCF provides a runtime environment for services, enabling you to expose CLR types as services, and to consume other services as CLR types.
