Visual Studio 2010 Beta1 includes the Windows 7 Beta SDK
Wondering how to use the new Windows 7 SDK with Visual Studio 2010 Beta1? The Windows 7 SDK Beta version of the Windows headers, libraries and Win32 tools ships with Visual Studio 2010 Beta1, but you'd probably prefer to work with the RC release of the Windows SDK for Win 7, that was released after VS2010 Beta 1.
It's easy to do. Just install the RC version of the Windows SDK for Windows 7 and .NET Framework 3.5 SP1 on your machine, and target the Windows 7 SDK RC release by following the steps outlined in this Visual C++ team blog post.
