title: Visual Studio Build Event Immediately Return
body: <p>I have a somewhat long-running post-build event (long enough to be annoying to wait for but short enough to be finished after each release compilation) that I want to return immediately to VS.  I've tried to run batch files with <code>start</code> but visual studio still waits for the <code>cmd</code> window to close before returning success.</p>
  
  <p>Is there a way to immediately return success when spawning this post-build event?</p>
  
  <p>Thanks.</p>
