  • Cleaner Setup: setup screens have been grouped into native, managed, and common buckets to help you more easily choose the components you need.
  • VC++ 2010 Compilers (32 & 64-bit): use the new C++ compilers and CRT that also ship in Visual Studio 2010 for improved run-time and design-time performance.
  • Microsoft Help System 1.0: the new help system introduced with Visual Studio 2010 that enables you to view documentation either online or offline and selectively choose which documentation to maintain offline.
  • .NET Framework 4 Tools and Reference Assemblies: use tools and reference assemblies updated specifically for .NET Framework 4 development.
  • MSBuild: support for .NET Framework 4 MSBuild in the SDK Command line for building native and managed applications using new Visual Studio 2010 project files (such as the vcxproj file for C++ applications).

The latest SDK is compatible with Visual Studio versions 2005, 2008 and 2010 as well as Express editions such as free Visual Studio 2010 Express (not all features work with all versions of Visual Studio).  It works well in most of the Microsoft Operating Systems such as Windows 7, Windows Server 2003 R2 (32-Bit x86), Windows Server 2003 R2 x64 editions, Windows Server 2008, Windows Server 2008 R2, Windows Vista and Windows XP Service Pack 3.
