About six weeks ago, the WF team published up the first four WF3->WF4 migration guidance documents, aimed at helping WF developers prepare and think about the new WF object model runtime.

Today, we published the next three documents in the series to the WF4 Migration Guidance document set. With today’s release, we begin moving from the general guidance and start to present cookbook material, addressing more specific scenarios and presenting code.

• WF Migration Overview (Already Live)
  Overview of the document collection and an initial starting place for the WF3 developer
• WF Migration: Best Practices for WF3 Development (Already Live)
  How to design WF3 artifacts so they are more easily migratable to WF4
• WF Guidance: Rules (Already Live)
  Discussion of how to bring rules-related investments forward into .NET 4
• WF Guidance: State Machine (Already Live)
  Discussion of WF4 control flow modeling in the absence of a StateMachine activity
• WF Migration Cookbook: Custom Activities (Now Live!)
  Examples and instructions for redesigning WF3 custom activities on WF4
• WF Migration Cookbook: Workflows (Now Live!)
  Examples and instructions for redesigning WF3 workflows on WF4
• WF Migration Cookbook: Workflow Services (Now Live!)
  Examples and instructions for redesigning WF3 workflow services on WF4
• WF Migration Cookbook: Advanced Custom Activities (Coming Soon)
  Examples and instructions for redesigning advanced WF3 custom activities on WF4

As I mentioned in the last post about the documents, these documents are initial draft releases that the team is releasing to you. For these, they are all written for the object model and features that are part of Beta 1. We will be updating the documents as additional releases of .NET 4 are publicly released, and the documents will address further scenarios with each release.

Also – again – the team will be supporting feedback and requests for the documents and accompanying sample code in the WF 4 forum on MSDN.

Happy reading!
