While working on code files, XAML files, EDMX files, and presumably any other type of file, leaving those files open and launching a debugging session causes the editors for those files to close. After debugging is stopped, Visual Studio is no longer able to open the editor for any file that was left open prior to starting the debugging session. Double-clicking any of these files shows a "No editor available" message in the status bar.The only resolution is to close and re-open the solution, or restart Visual Studio.
