  • 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.
