Windows Communication Foundation (WCF) is Microsofts strategic vision for creating distributed applications in the Service Oriented Architecture (SOA) era. This course provides comprehensive coverage of WCF, explaining how to implement best–of–breed SOA solutions using the latest features available in WCF 4 and Visual Studio 2010.
