This year at SD West 2009, Jesus Rodriguez presented the session Beyond the WCF ABC: WCF Extensibility Deep Dive:

Windows Communication Foundation (WCF) provides a rich messaging framework that extends beyond its capabilities for modeling and implementing services. One of the aspects where WCF really shines when compared with competitive Web services stacks is its rich extensibility model that allows developers to customize the default behavior of the framework. The better we understand the WCF extensibility model the better chance we have to make the right use of WCF in real-world applications. In this session, we dive deeply into the WCF extensibility model, detailing the different extensibility points of WCF subsystems such as Channels, Hosting, Security, Metadata, Encoding, and others. Specifically, we provide practical demonstrations of how custom channels, behaviors, operation invokers, authorization managers, and metadata extensions can be used to extend WCF effectively without affecting the consistency of the programming model. We also highlight a set of best practices developers should consider to address their specific scenarios properly when extending WCF.
