Write Black and Blue Get Green Free
GhostDoc is a free Visual Studio add-in that automatically generates XML comments by intelligently deducing comments from member name and type or by using existing documentation written by someone else in a base class or an interface.
This tool is purely intelligent and simply amazing. With tools such as this there simply is no excuse for developers whose code looks all black and blue to not add some green for free!
