Hi and welcome to another Visual Studio 2008 Training Kit screencast.
This session was presented by Matt Winkler and is the from the
Visual Studio 2008 training kit available from http://go.microsoft.com/?linkid=7602397.
The major enhancement to Windows Workflow Foundation (WF) inside the .NET Framework 3.5 is the integration with the Windows Communication Foundation (WCF) in the functionality known as Workflow Services. This session will introduce the reasoning behind wanting to implement services as workflows and exposing workflows as services and then discuss the architectural foundations behind it. This technology was built upon the existing extensibility mechanisms in the framework and allows one to easily consume services as well as create them using WF. This session will introduce the basics of Workflow Services and then proceed to discuss the more advanced scenarios of duplex communication and conversations with multiple parties over the same contract.
