I'll be in Albany, New York - well, Latham, really - this coming Tuesday (January 13th) to present to the Tech Valley .NET Users Group on "Interacting with Services in Windows Workflow Foundation."
Here's the outline of the talk, straight from their site.
Workflow Foundation (WF), released as one of the four pillars of the .NET Framework 3.0, is a very powerful technology for building robust, scalable, and flexible applications capturing complex business processes. This talk will provide a short overview of core capabilities and the underlying infrastructure - including workflow runtime, instances, and activities as well as tracking and persistence services. We'll then take a deeper dive and demonstrate techniques for integrating and extending your workflows using both local services and external services hosted in WCF.
See you there!
