The fuss created by the open beta for Windows 7 has obscured another piece of news that is relevant to devs like us: the Win7 Beta SDK
has also been released.
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 StudioÂ® 2008, including Visual Studio Express Editions, which are available free of charge.
