The Microsoft Windows Software Development Kit (SDK) Update for Windows Vista is a comprehensive developer toolkit designed to replace the original November 2006 Windows SDK for Vista. It provides all the necessary documentation, code samples, header files, libraries, and tools required to build applications utilizing the native Windows Vista APIs and modern framework technologies. Core Component Upgrades
Updated C++ Compilers: This update packages the exact same stable compilers that shipped with Visual Studio 2005 Service Pack 1.
Unified Developer Environment: It consolidated the previously scattered Platform SDK, .NET Framework SDK, Tablet PC SDK, and Windows Media SDK into one unified installation kit.
Cross-OS Compatibility: In addition to Vista, developers can use it to build applications targeting Windows XP, Windows Server 2003 SP1, and Windows Server 2003 R2. Supported Frameworks
The kit features built-in content and documentation filtering optimized for .NET Framework 3.0 technologies. It specifically includes the APIs for: Windows Presentation Foundation (WPF) Windows Communication Foundation (WCF) Windows Workflow Foundation (WF) Windows CardSpace System Requirements & Installation
Storage Footprint: The installation requires a minimum of 2.0 GB of free hard drive space.
Prior Dependencies: To build .NET Framework 3.0 applications, the corresponding .NET Framework 3.0 Runtime Components must be separately active on the machine.
Installation Conflict: This package does not overwrite the older version gracefully. If you already have the original November 2006 Windows SDK for Vista installed, you must fully uninstall it first before running this update.
