State Machine in WF vNext

About a year and a half ago, I wrote a post regarding the fact that they removed the State Machine when rewriting Workflow Foundation (WF) to create WF4. When listening to one of the PDC 2010 presentations regarding WF vNext, I found out that one of the news for the next version of WF was the State Machine. The other news coming with vNext, directly from the list in the presentation:

• State Machine
• C# Expressions
• Versioning
• Dynamic Update
• Enhanced Workflow Designer
• New Activities
  • Database, SendMail, REST Client, …
• WCF Workflow Service Improvements
  • Security, Contract First
• Partial Trust
