title: What is the difference between Version and 'Runtime Version' in .Net?
body: <p>When I open the properties window of one of the referenced dlls in my project in Visual Studio I see a Version and also a runtime version .</p>
  
  <p>Actually it is Rhino.Mocks library I am checking. And I see </p>
  
  <ul>
  <li>Runtime Version : v2.0.50727</li>
  <li>Version : 3.6.0.0</li>
  </ul>
  
  <p>What is the difference? (Does it mean I am not able to use 3.6.0.0 of the Rhino Mocks?)</p>
