title: Visual Studio 2010 remote debugging: Debugging symbols are not loaded for this document
body: <p>This is a weird problem, which luckily (?) also happens on other machines.</p>
  
  <p>I've never had problems with debugging, and now I have: it shows an exclamation mark at my breakpoints which says :'The debugging symbols are not loaded for this document'.</p>
  
  <p>The difference with other projects is that I run this web application in IIS:</p>
  
  <ul>
  <li>I've created a new website in IIS 7.5 (win7), listening on port 80 to
  local.comparer.nl </li>
  <li>I've added the url local.comparer.nl to my hosts
  file, redirecting it to 127.0.0.1 </li>
  <li>I've edited the start page of the
  project (asp.net 3.5) to local.comparer.nl in 'use local IIS
  webserver'</li>
  </ul>
  
  <p>When I start the site, it first says 'unable to start remote debugging'. I don't know why it looks for remote debugging, but when I started the remote debugging monitor, it still didn't work.</p>
  
  <p>When I unloaded the debugging monitor, it didn't complain about the remote debugging anymore, but the exclamation mark still was there.</p>
  
  <p>Solutions which -sometimes- help at my colleagues pc's:</p>
  
  <ul>
  <li>Delete everything from the \bin directory and rebuild</li>
  <li>Rebuild again (n number of times)</li>
  <li>Choose 'clean solution'</li>
  </ul>
  
  <p>Any idea?</p>
