Does AppFabric help with Windows Workflow Foundation development?

What are the advantages of using WF 4.0 in an AppFabric environment, for ASP.NET MVC? What additional hoops do you have to jump through if you don't have AppFabric? What bad stuff does AppFabric do tha开发者_StackOverflow中文版t I should be aware of?

Appfabric is more of a runtime thing then a development thing. Sure it has an API you can use from your activities but for the most part it just adds managment and configuration UI to the IIS 7 manager.
