No, this is not a joke. :0) Though I am technically on the C# team, the debugger which I work on supports all sorts of languages and platforms.
Several members of the C++ and Debugger teams will be converging on an MSDN chatroom this Thursday to answer your questions. More info here; this is the blurb:
Debugging is a difficult process no matter what kind of code or platform an application is built with or on. As C++ developers know, worst-case scenarios like heap corruptions only make it that much more difficult. Fortunately, Visual C++ .NET developers have a powerful tool at their fingertips for just these kinds of situations: the Visual Studio .NET Debugger. Join members of the Visual Studio .NET Debugger and Visual C++ .NET teams for help, tips, tricks, and techniques for debugging C++ code.
