VS 2005 Visualizers for managed code only
I just found out that the cool visualizer feature of VS 2005 is for managed code only. This feature is extremely cool and I was hoping that it would have been available to unmanaged C++ projects. Duncan Mackenzie wrote up an entry called "Scott Nonnenberg on Debugger Visualizers in VS 2005":http://weblogs.asp.net/duncanma/archive/2004/04/17/115418.aspx, where you can find a lot more information on debugging.
The visualizer feature allows you to write any Winform code you want in order to debug a variable. You basically select your watch variable, for instance, and select a visualizer like "Image", "XML", "spreadsheet", etc.
