Windows Workflow Foundation 4 (WF4) provides a flexible, declarative programming model and a brand new runtime architecture that makes it easily accessible for .NET developers. What that means for developers is that WF4 can make it easier to put together your application logic, encapsulate complex control flow logic, and abstract complex programming tasks. WF4 also composes nicely with Windows Communication Foundation (WCF) for writing declarative workflow services that support content-based message correlation and long-running duplex conversations. When you combine the framework features with the new AppFabric capabilities in Windows Server to host and manage your workflows and services , you have a comprehensive workflow solution in Windows. In this session we will look at examples of how you can use WF4 in your application and service development to speed your development and simplify complex tasks, as well as how to build powerful, manageable workflow services with WF, WCF and AppFabric. Come find out how this powerful, testable framework can help you and your development team take programming to the next level.
