Windows 7 Beta was announced by Microsoft CEO Steve Ballmer at this years Consumer Electronic Show in Vegas. Today, Microsoft has released the SDKs for both the Windows 7 Beta and the .NET Framework 3.5 SP1 which is included in Windows 7 Beta. Both Windows Vista and Windows Server 2008 were shipped with .NET Framework 3.0.
The Windows SDK contains a set of tools, code samples, documentation, compilers, headers, and libraries that developers can use to create applications that run on Microsoft Windows. You can use the Windows SDK to write applications using the native (Win32/COM) or managed (.NET Framework) programming model.
This release of the Windows SDK supports Microsoft Visual Studio 2005 SP1, Microsoft Visual Studio 2008 SP1, and the Microsoft Visual Studio 2008 Express Editions development environment.
