title: C# reflection and finding all references
body: <p>Given a DLL file, I'd like to be able to find all the calls to a method within that DLL file. How can I do this?</p>
  
  <p>Essentially, how can I do programmatically what Visual Studio already does?</p>
  
  <p>I don't want to use a tool like <a href="http://en.wikipedia.org/wiki/.NET_Reflector" rel="noreferrer">.NET Reflector</a> to do this, but reflection is fine and probably necessary.</p>
