title: VS-2012 : Breakpoint will not currently be hit. No symbols have been loaded for this document
body: <p>I am not being able to debug the code for a MVC4 application in VS-2012. The same code was running fine a few days back. Error as below:
  Breakpoint will not currently be hit. No symbols  have been loaded for this document.</p>
  
  <p>I have tried below possible ways:</p>
  
  <ul>
  <li>Cleaning and rebuilding the solution.</li>
  <li>Setting 'Just my code' to false and true both.</li>
  <li>Repaired VS.</li>
  <li>Cleared the bin and obj folders also related GAC and temp asp.net folder.</li>
  <li>Checked in Debug->Windows->Modules, it gives 'Can not find or open PDB file', when tried to load manually, it can't find the pdb file though file is present in the mentioned location.</li>
  <li>Checked that code is building in Debug mode with no optimization and Debug set to true in web.config file as well.</li>
  <li>The problem persists even if I create a new project in VS.</li>
  <li>Also tried reverting all the changes and took the latest version from TFS.</li>
  </ul>
  
  <p>Any help on this is highly appreciated as I have gone through many threads but couldn't find a solution. </p>
