title: Adding a dll file to a C# project
body: <p>It's a beginners question, but...</p>
  
  <p><a href="http://a3.vox.com/6a00c2251e5b66549d00e398ca81eb0003-pi">Image of dll reference and dll included in project file http://a3.vox.com/6a00c2251e5b66549d00e398ca81eb0003-pi</a></p>
  
  <p>If you look at the image above, there is the "Bass.Net" dll added as reference and also directly as file in the project.</p>
  
  <p>Can someone tell me what's the point of doing that?</p>
