For the July 2006 issue of MSDN Magazine, Sergey Mishkovskiy wrote a cool article on integrating Windows Desktop Search into Visual Studio through a custom add-in.  However, it was based on WDS 2.x, and since then Microsoft has released WDS 3.x (what Windows Vista incorporates).  As such, Sergey has graciously updated his add-in to work with 3.x, and we've made it available for download from the Web site.  Definitely worth checking out.
