Part of Microsoft's radical WinFX API is the Indigo foundation, more formally known as the Windows Communication Foundation, or WCF. Pro WCF: Practical Microsoft SOA Implementation is a complete guide to WCF from the service-oriented architecture (SOA) perspective and shows you why WCF is important to web service development and architecture.
The book covers the unified programming model, reliable messaging, security, the peer-to-peer programming model, and more. Youll also learn how to move your current DCOM and .NET remoting applications to WCF, and how to integrate those applications with new WCF-based applications. Youll want to get ahold of a copy because it:

• Contains a comprehensive WCF programming model
• Explains how queue management and reliable messaging work in WCF
• Discusses implementing transaction support in WCF
• Shows how to make WCF services interoperable with other SOA offerings
• Thoroughly covers WCF security topics and concerns
