WPF MVVM: Prismv4 -- Is it necessary to use the Microsoft Async CTP if you use this?

Basically, I was wondering if it's necessary (or better) to use the Microsoft Async CTP if you plan to use Prismv4. I know when I was skimming over the features of Prismv4 I found something about Asynchronous binding, but I wasn't sure if it was something baked into Prismv4 or the old way of creating threa开发者_如何学编程ds and the such.

I don't believe these are related. The Asynchronous Binding in Prism 4 doesn't use this capability.
