title: Can't edit and continue when using Visual Studio 2010 on a 64 bit machine, app targets x86
body: <p>I'm having some problems with <a href="https://docs.microsoft.com/en-us/previous-versions/visualstudio/visual-studio-2010/ms164926(v=vs.100)" rel="nofollow noreferrer">Edit and Continue</a> when using Visual Studio 2010 on a Windows 7 64 bit machine. I've ensured the following</p>
  
  <ol>
  <li>Edit and Continue is enabled under Tools>Options>Debugging>Edit and Continue</li>
  <li>My solution platform is set to x86</li>
  <li>My solution configuration is set to Debug</li>
  <li>All my projects are building for Debug and x86</li>
  <li>For all projects under Projects>Properties>Build the <em>Optimize code</em> is <strong>unchecked</strong></li>
  </ol>
  
  <p>When I hit a break point and try to edit I and confronted with the following message.</p>

  <p>This is happening for me for all projects that I create whether they are WPF/Win Forms/VB.NET/C#/.NET 4/.NET 3.</p>
  
  <p>Any ideas? </p>
