My last blog post was a step by step walkthrough on how to build a simple version of the source code outliner.
Over the weekend, the full version of the Source Code Outliner was released and can be downloaded from here: http://www.microsoft.com/downloads/details.aspx?FamilyId=55E6FE58-2163-45E7-92D0-B9C298FBDFAD&displaylang=en.
If you're interested in more productivity tools for Visual Studio, stay tuned as the Visual Studio Extensibility team will be releasing a few more in the coming weeks.
If you like the source code outliner and want to improve on it, check out the source code on CodePlex at: http://www.codeplex.com/SourceCodeOutliner/.
Or if you'd prefer to start from scratch and build one on your own, check out my last blog post: http://blogs.msdn.com/quanto/archive/2008/01/22/building-your-own-visual-studio-source-code-outliner-extension.aspx
