title: VS2012: Unable to attach to process but only for aspx pages and code behind
body: <p>I'm experiencing something very weird.
  I was able for a long time to attach to process to my published web site.
  Out of the blue, I cannot anymore.
  My breakpoints are not hit. What is very strange is that this happens only for "pages" (aspx and aspx.cs files). The referenced dll/libraries are ok, I can debug them!</p>
  
  <p>I would expect the opposite.</p>
  
  <p>Any suggestion?</p>
  
  <p>Thanks,
  Roberto</p>
