title: F# compilation without msbuild
body: <p>how do I simulate, from the command line, compiling an F# file with fsc.exe:</p>
  
  <ul>
  <li>without resorting to msbuild explicitly</li>
  <li>setting the framework version to another one of my choosing (for example .Net 3.5)</li>
  </ul>
  
  <p>?</p>
  
  <p>So far it seems that I need to make a project at all costs, but that is simply not an option in my scenario.</p>
