From MSDN : " Windows Communication Foundation is... a part of the .NET Framework that provides a unified programming model for rapidly building service-oriented applications that communicate across the web and the enterprise.

Windows Communication Foundation (WCF) is Microsoft 's programming model for using managed code to build unified Web services and other distributed systems that can talk to each other. WCF focuses on connecting XML to programs that are built using development languages supported by Microsoft, such as VB.NET and C# . To support this cross-language communication, WCF uses the extensible Simple Object Access Protocol ( SOAP ).
