Generate XML documentation comments for /// in Visual Studio 2010 C++

GhostDoc will now insert XML comments for C++ elements. Just put the cursor on an element and press Ctrl+Shift+D.

GhostDoc has a free version for personal use that will already do this.

This functionality isn't buit-in. You can try using Visual Studio add-ins. I haven't used Atomineer Utils Pro Documentation myself, but it looks promising. It generates documentation comments and supports C++. It costs $10 though.

CppTripleSlash creates xml doc comment stubs in c++ files when /// is typed, similar to what is available for c# in visual studio. This also has some basic intellisense for completing XML doc comments.
