title: VB Visual Studio doesn't update the bin/debug folder
body: <p>A friend was working on a Visual Basic program in Visual Studio 2010 (Express) and all of a sudden, after the code is changed or the form is modified, Visual Studio refuses to update the program when we go to debug/build it.  It doesn't update the "MyAppName".exe at all.</p>
  
  <p>I tried following the accepted answer to <a href="https://stackoverflow.com/questions/21470297/vb-net-code-not-executing-the-way-it-should-under-visual-studio">this</a> question, which suggests deleting all the content in the bin/debug/ folder, but when I try to build his program, it simply repopulates these files:  </p>
  
  <ul>
  <li>MyAppName.vshost.exe.config</li>
  <li>MyAppName.exe.config</li>
  <li>MyAppName.vshost.exe</li>
  </ul>
  
  <p>(I made sure I had closed VS prior to deleting, so that all the files were removed.)</p>
  
  <p>If you press <code>F5</code> or the debug button, VS complains:</p>
  
  <blockquote>
    <p>Visual Studio cannot start debugging because the debug target 'C:\PATH_TO_PROJECT\bin\debug\MyAppName.exe' is missing...</p>
  </blockquote>
  
  <p>and so on.</p>
  
  <p>Any help?</p>
