A Good Introduction to Windows Workflow Foundation

Developing workflows in applications is a common task for developers. MS is providing what seems to be a pretty well-rounded workflow framework in .Net 3.0. Here is a nice introduction to the Windows Workflow Foundation, as well as two simple examples.

To bring workflow to the masses and allow for long-running workflows in
applications and servers, Microsoft will introduce the much-anticipated Windows
Workflow Foundation (WinWF) as part of the .NET Framework 3. WinWF provides a workflow engine, a programming model, and a set of tools for rapidly building
workflow-enabled solutions. It offers a single workflow technology for Windows
that serves as a base for Microsoft products as well as ISV and customer
solutions. Microsoft itself will be utilizing WinWF in the near term to
workflow-enable several Microsoft products such as Microsoft Office 2007 and
Microsoft BizTalk Server.
