title: How do I remove a project configuration in Visual Studio 2008?
body: <p>I have a Visual Studio 2008 solution into which I have imported a number of pre-existing projects.  The projects are mixed-language sample code (C#, VB, C++/CLI).  They currently have multiple configurations, but I want each project only to have only a single "Debug" configuration.</p>
  
  <p>In the configuration manager, I deleted the other configurations (e.g. "Release"), but as I did so there was a warning message to tell me that they would not be deleted from the individual projects.</p>
  
  <p>And indeed when I navigate to an individual project, it still has "Release" and other configurations, even though at the solution level there is only "Debug".</p>
  
  <p>How can I best remove these extra configurations from each project?  Am I overlooking some way to do this in the GUI, or should I just edit the project files directly?</p>
