title: Visual Studio 2010: Solution Explorer not showing project directory structure
body: <p>I'm using a new install of MS Visual Studio 2010 and cannot seem to get the Solution Explorer to show the project directory structure (instead of a just list of all files in the project for each project in the solution). There is no "show all files" button.</p>
  
  <p>Any ideas on where I might find the option?</p>
