title: Visual Studio + Mono: 'Gtk' could not be found
body: <p>I've just installed <a href="http://www.go-mono.com/mono-downloads/download.html" rel="nofollow">mono 3</a> for Windows, and now I've opened a project that uses "Gtk". I'm trying to compile it but it's telling me "Gtk" could not be found, which I'm fairly certain mono installed, but evidently didn't set up the paths for.</p>
  
  <p>How do I tell VS2012 where all the mono stuff is?</p>
  
  <hr>
  
  <p>I've downgraded to mono 2. No luck yet.</p>
