title: How to resolve Antlr3 dependency hell
body: <p>I have a asp.net MVC 4 project with MEF and RavenBD.</p>
  
  <p>When the project loads it throws this exception : Could not load file or assembly Antlr3.Runtime.dll</p>
  
  <p>I have found that both RavenDB and WebGrease (installed with MVC 4) use Antlr3. But WebGrease comes with its own Antlr3 dll, signed by Microsoft - PublicKeyToken 31bf3856ad364e35</p>
  
  <p>Antlr3 default PublicKeyToken is eb42632606e9261f.</p>
  
  <p>RavenDB and WebGrease use the same version of Antlr3 3.3.1.7705</p>
  
  <p>How can I resolve this problem?</p>
