title: Visual Studio: Set default startup project
body: <p>I have a Visual Studio 2010 solution with several projects.
  One of the projects is set as the default project, but I want to change that by default.</p>
  
  <p>I know that I can right click the project I want to be the startup project and select "Set as StartUp project", but this setting will be stored in the user's files (.slo and .user files).</p>
  
  <p>As a company policy, we don't check these files in the source control system, therefore when another user opens the solution it will have a different project as the startup object.</p>
  
  <p>Is there another way to set these values? Something like a setting on the .sln or .proj files?</p>
  
  <p>Thanks</p>
