title: Visual Studio 2012 random debugger startup failure: Unable to start program
body: <p>I have a managed startup project and quite often when I press F5 the Visual Studio complains with dialog "Unable to start program '...\test.exe'" (no additional information). The process test.exe is actually started in the background but when I try to attach the debugger to it, VS complains that debugger is already attached. To be able to debug again I have to manually kill the test.exe process and restart the VS. I run VS as Administrator. Thanks!</p>
