I came across the Power Toys for Visual Studio site at Rob Caron’s blog
Power Toys for Visual Studio are small tools that provide aid to developer
pain-points or assist in diagnosing development-related issues. In addition to
providing support, the power toys are released as Microsoft Shared Source to
provide sample code to real-world solutions and allow for
collaborative-development.
It contains information about the various power toys under development, such as the Best Practice Analyzer for ASP.NET and the MSBuild Extras – Toolkit for .NET 1.1 “MSBee” and developer tools such as IronPython.
