title: Devenv ProjectConfig switch - Win32 and x64
body: <p>Running Visual Studio 2008 interactively, I can build the project successfully for both the x64 and Win32 targets.  However, if I invoke devenv, regardless of my /projectconfig argument, it always performs the x64 build:</p>
  
  <pre><code>devenv /Rebuild Release MySolution.sln /projectconfig "Release|Win32"
  
  Microsoft (R) Visual Studio Version 9.0.21022.8.
  Copyright (C) Microsoft Corp. All rights reserved.
  ------ Rebuild All started: Project: my-project, Configuration: Release x64 ------
  </code></pre>
  
  <p>Note that the /projectconfig arg doesn't match the Configuration: output.  Am I missing something simple?  It works fine within the IDE but there are a bunch of targets and I'd prefer to script it.</p>
  
  <p>Thanks in advance!</p>
