title: How do I compile a single source file within an MSVC project from the command line?
body: <p>I'm about to start doing some benchmarking/testing of our builds, and I'd like to drive the whole thing from a command line. I am aware of <code>DevEnv</code> but am not convinced it can do what I want.</p>
  
  <p>If I could have a single file built within a single project, I'd be happy.</p>
  
  <p>Can this be done?</p>
