Framework Source Code Stepping
There is no greater source of documentation than the actual source code of a function. By configuring Visual C++ to be able to step through the ATL, MFC, and .NET Framework libraries, it is possible to gain a much greater depth of understanding about problems that are occurring, and why certain libraries behave like they do. Although it is never safe to rely on undocumented behaviour or implementation specifics, the actual source code can provide a great supplement to the MSDN documentation, and significantly enhance developer productivity. With a little effort and attention to detail, setting up Visual C++ to be able to step into the source code of any of Microsoft's libraries is easily achievable.
