In the rush of the past week, I forgot to post that "Essential Windows Communication Foundation" has gone to the printer and will be shipping soon!
One of our goals was to incorporate the new WCF features of the .NET Framework 3.5 and Visual Studio 2008. So, in addition to the core WCF topics, you'll also see coverage of areas such as RSS/ATOM syndication, peer networking, REST, Workflow integration, and new tools/integration with VS 2008.
Another goal was to have the book on shelves in time for the worldwide 2008 launch events (BTW, I'll be speaking at most of the ones in the northeast), and it seems that's going to happen!
For those of you who pick up a copy, you have our thanks! We hope it helps you along your way to creating fantastic WCF applications with .NET 3.x.
