title: How to set a project output platform to x86 in Visual Studio 2010
body: <p>In my solution with several projects I am trying to change the <code>Platform</code> from Any CPU to x86.  But x86 is not in the drop down.  What do I need to do to be able to choose x86?</p>
  
  <p>I need to change to x86 because of an <code>System.BadImageFormatException</code> error, as per this question: <a href="https://stackoverflow.com/questions/2048914/what-causes-system-badimageformatexception-when-constructing-system-data-sqlite-s">What causes System.BadImageFormatException when constructing System.Data.SQLite.SQLiteConnection</a></p>

  <p>And, in a possibly related problem, the newest project in the solution is missing one of the configurations from the configuration drop down:</p>

  <p>It should have a "Staging" configuration like all of the other projects, but does not.  How do I add it?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>If I choose the "New ..." option, then it asks me to copy from "Any CPU".  If I copy from "Any CPU", isnt that just the same as using "Any CPU" in the first place?</p>
