I’m presenting at tomorrow’s St Louis .NET User Group meeting and will focus on WCF. 

"Windows Communication Foundation (WCF) is the framework for building distributed applications in .NET. WCF provides a foundation to build and expose services across a variety of communication methods. In this session we will cover the ABC’s of WCF and then dive into a real-world example WCF service that demonstrates how WCF can support services the way you need it to."

Hope to see you there!
