A little while back we published the Search Work Items for TFS 2010 extension in the Visual Studio Gallery. Noah Coad recently added Cory and I as Developers on the existing Search Work Items CodePlex project. Over the weekend I uploaded the new source code containing our Visual Studio and TFS 2010 updates. Feel free to check out the source code.
You can run the code locally but just be sure you have the Visual Studio 2010 SDK installed and you are pointing at your experimental instance of Visual Studio. To do this, just right click on the project in the Solution Explorer, click properties, click the Debug tab, then set the following properties:
Start external program: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe
Command line arguments: /rootsuffix Exp

Here's the link to the source code:

We're planning on publishing the source code to all our other extensions soon once we get some spare time. I'll post another blog once they're out there.
