I’m happy to announce that the WF 4 whitepaper I wrote this spring has been published on MSDN and is ready for viewing.  This was a fun paper to write digging into the new bits for WF coming in the framework.  I’m very excited about the new models for activities and workflows and being able to do totally declarative workflow programming.  The new designer model is awesome and I can’t believe how easy it is to rehost the designer. 

A Developer’s Introduction to Windows Workflow Foundation (WF4) in .NET 4 Beta 1

The paper is based on Beta 1, which means you can download the bits and play along. 

At the same time, Aaron’s paper on WCF in .NET 4 has been published and contains a lot of the workflow service content as well as all the new features coming in WCF 4.
