Over the past several months I?ve been working on a new Power Tool for Visual Studio with Andrew Bragdon and Brown University. The purpose of the power tool is to get feedback from users (that means you!) about using a Code Bubbles like experience for debugging through code inside Visual Studio. The Power Tool will be called Debugger Canvas and will be available for download on Microsoft DevLabs early next month. It will require Visual Studio 2010 Ultimate SP1 (or the trial version), and there will be a DevLabs forum for public feedback, discussion, questions and answers, etc. In the mean time you can find out more information on http://research.microsoft.com/debuggercanvas and also watch the demo video below.
