Is there a difference between WAS and AppFabric

Question

I understand that AppFabric has both caching capabilities along with hosting WCF/WF services. I have seen Windows Activation Service used interchangeably with AppFabric when talking about hosting services on IIS 7.0

Are both one and the same?

No, they are not. AppFabric is built on top of the WAS facilities, but adds a lot more things including better monitoring and configuration tools, good Workflow Services hosting, tracking and reporting for persistent services/workflows and a few more things.
