OzCode enhances C# debugging in Visual Studio. The extension was originally called BugAid (see my review), but in June 2013 became a part of CodeValue. Recently they filmed a demo video on Channel 9 showing major features in action. On November 27 OzCode v1.0 Release Candidate 3 was out, it looks like the public launch is just around the corner. You can download the free beta for VS 2010+ from the official website.
