The October issue of MSDN Magazine just came out, and featured a focus on the Async language features coming in C# 5 and VB 11. Michael Desmond interviewed Mads Torgersen and me for the Editor’s note, which you can find here:

There are also a bunch of great articles included, by the team, which I would strongly recommend checking out:

1. Asynchronous Programming: Easier Asynchronous Programming with the New Visual Studio Async CTP by Eric Lippert
2. Asynchronous Programming: Pause and Play with Await by Mads Torgersen
3. Asynchronous Programming: Understanding the Costs of Async and Await by Stephen Toub'

Enjoy!
