Microsoft has released the Windows 7 SDK beta. “The Windows SDK for Windows 7 and .NET Framework 3.5 SP1: BETA provides the documentation, samples, header files, libraries, and tools (including C++ compilers) that you need to develop applications to run on Windows 7 BETA and the .NET Framework 3.5 SP1. To build and run .NET Framework applications, you must have the corresponding version of the .NET Framework installed. This SDK is compatible with Visual Studio 2008, including Visual Studio Express Editions, which are available free of charge.” Note that the SDK will most definitely change before Windows 7 goes final.
