title: What causes Visual Studio to hide files on some machines but not others?
body: <p>I have a Visual Studio solution which appears to be fine on one machine, but on another machine it has decided to hide all of the files in a single project.</p>
  <p>None of the nodes can be double-clicked, and Studio refuses to allow any context menus to function.</p>
  <p>What might cause this effect in Visual Studio?</p>

  <p>The source appears to be identical on both machines. Is this some strange option I've triggered? Restarting Visual Studio appears to have no effect.</p>
  <p><strong>Update</strong>: If I click the ShowAllFiles button at the top of the solution the organisation of the project changes to the following:</p>
  <p><a href="https://i.stack.imgur.com/Y5XUC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Y5XUC.png" alt="enter image description here" /></a></p>
  <p>This appears to be the root of my c: drive.</p>
  <p>Also, FWIW, I have 8 other projects in this solution. None of them have this issue on either machine.</p>
  <p>8/9 projects (including the problematic one) are console applications. The 9th is a library which the others all use.</p>
