Microsoft Windows Software Development Kit Update for Windows Vista

The Microsoft Windows Software Development Kit (SDK) Update for Windows Vista provides documentation, samples, header files, libraries, and tools you need to develop applications that run on Windows. This release of the SDK supplies updated compilers and documentation.
The updated compilers are the same ones that recently shipped in Visual Studio 2005 Service Pack 1. This SDK also includes the samples, headers, tools and libraries that shipped in the Software Development Kit for Vista in November, 2006.
This download contains the SDK only. To build .NET Framework 3.0 applications, you must have .NET Framework 3.0 Runtime Components.
This release of the SDK is intended to replace the Windows SDK for Vista. If you have already installed the Windows SDK for Vista and you want to install the Windows SDK Update for Vista, you will need to first uninstall the Windows SDK for Vista.
The Windows SDK Update for Vista includes content for application development with the APIs in Windows Vista, including the .NET Framework 3.0 technologies: .NET Framework 2.0, Windows Presentation Foundation, Windows Communication Foundation, Windows Workflow Foundation, and Windows CardSpace. This SDK is designed for use with Windows Vista (which includes Framework 3.0). The Windows SDK Update for Vista also supports creating applications for Windows XP, Windows Server 2003 SP1, and Windows Server 2003 R2. This release of the Windows SDK is compatible with Microsoft Visual Studio 2005 and the Visual Studio 2005 extensions for .NET Framework 3.0 (WCF & WPF), November 2006 CTP.

ï¿­ The .NET Framework 3.0 tools and samples contained in this SDK are designed to work on Windows Vista or on Windows XP SP2 and Windows Server 2003 SP1 with the .NET Framework 3.0 Runtime Components installed.
