title: Unable to start debug in Visual Studio 2005
body: <p>My "Start debugging" button and element menu are greyed out... but only on one of my projects (an ASP.NET website). I have no idea what I have done to disable it.</p>
  
  <p>I already checked everything in the Property page of both the solution and project. I even compared it to another project, but nothing seems to do the trick... maybe I missed an option ?</p>
