I keep trying to work on a simple new ASP.NET Web Forms Application, and the Toolbox is empty. I have found an online article that shows how to delete the .tbd files, this restores the toolbox (it was empty the first time I loaded it, right after install), but after a while it always goes completely empty, and the only fix is to save work, exit, delete the .tbd files, and relaunch Visual Studio 2012 Ultimate. This is unworkable.
Visual Studio/Team Foundation Server/.NET Framework Tooling Version
