For Visual Studio 2008 there is a small but large incremental Source Outliner element on Codeplex ( http://sourcecodeoutliner.codeplex.com ).
Does anyone know if there is an equivalent tool for Visual Studio 2010?
There Solution Navigator 's Performance Tools for Visual Studio Extensions , it looks like it is doing the same.
Use the Power Tools Performance Solution Navigator
You can install DPack and use its Code Explorer .
