Our team has posted a set of WF 4 Migration documents on MSDN.

You'll find 4 papers initially -

  • an overview document which introduces migration concerns and what to do for the WF3 developer.
  • a best practices for WF3 development paper - how to design your WF3 artifacts today to help with the move to WF4
  • a document on Rules guidance which I've authored
  • a document on State Machine guidance

 You can find them here:


We hope you find these documents useful, and I am personally interested in hearing from the Rules folks on the guidance I've provided in the Rules document.
