title: Error while trying to edit code in debugging mode in VS2013
body: <p>I'm a C# programmer and recently I've installed Visual Studio 2013. The problem is when i set a break point or get an error and trying to edit the codes while debugging I get this error and I couldn't find the same error searching on Google.</p>
  
  <blockquote>
    <p>Changes are not allowed for this module as it was not built for
    changes while debugging or the target .NET runtime version does not
    support it</p>
  </blockquote>
  
  <p>I also tried to check the options on <code>Tools -&gt; Options -&gt; Debugging -&gt; Edit and Continue</code>, But didn't help. </p>
  
  <p>Any idea what the problem is?</p>
