title: Check if function is called within solution
body: <p>I have a really large <code>solution S</code> with several projects, <code>dll</code>s, etc.</p>
  
  <p>I need to document which classes and methods from one <code>dll D</code> (which we have writen, it ia our dll with source code, almost ~500 functions) are actually used  within a <code>solution S</code>, so that I can get in my doc only functions that are actually used.</p>
  
  <p>Is there any program/hack/solution to such a problem? Because 500 seems to be a large number, and using <code>"Find &lt;function name&gt; in entire solution"</code> manually seems hell to me.</p>
  
  <p>Any ideas? How can I get some kind of <code>debug info</code>?</p>
  
  <p>We are using <code>MCVS 2010</code> </p>
