I've received many requests for a more in-depth article on the features of the Concurrency Visualizer in VS2010. Well, I'm happy to report that I've come through with an article entitled "Performance Tuning with the Concurrency Visualizer in Visual Studio 2010" that appeared in the current (March 2010) issue of MSDN Magazine. The article and a screenshot of the tool even made it to the front cover. I highly recommend reading that article if you want to make the most out of this parallel performance analysis tool. The article may be viewed at http://msdn.microsoft.com/en-us/magazine/ee336027.aspx.
