While I was exploring some great features of Orcas I came across this interesting great blog post that describes some new features in the profiler that are now available with Visual Studio Team System "Orcas" beta 1. Here's short desciption from this blog
With the recent release of the first Beta for Visual Studio Team System (codename Orcas) customers will get their first chance to see all the great new features that we are adding to the product. For the profiler in particular we’ve added some very cool new features that I’m really happy to finally be able to reveal publicly
Don't miss to visit this blog and this feature !
