title: How to determine why visual studio might be skipping projects when building a solution
body: <p>I am debugging someone else's work and the solution is quite large. When I try to build the entire thing, several projects within the solution don't build and just skip. Viewing the output window during the build process says:</p>
  
  <blockquote>
    <p>1>------ Skipped Rebuild All: Project: pr1lib ------</p>
  </blockquote>
  
  <p>How can I determine why these builds were skipped? I am unable to find additional output.</p>
  
  <p>This is with VS2008 and the solution is comprised of c# and c++ code.</p>
