title: Can't add project reference with same name
body: <p>I have a VS2013 solution in which I have the following structure (as an example):</p>
  
  <pre><code>My Solution
  |--&gt;My Company
  |   |--&gt; Common
  |--&gt;Common
  |--&gt;Web
  </code></pre>
  
  <p>As you can see, I have two projects named "Common" - the one under "My Company" is a company-wide project that is used in all solutions, with a bunch of common code. The other is common code the specific project.</p>
  
  <p>If I try to add both <code>My Company\Common</code> and <code>Common</code> projects as references to the <code>Web</code> project, I get this error message:</p>

  <p>I don't recall this happening in prior versions of Visual Studio. How can I add a reference with the same name (note that the underlying assembly names are not the same).</p>
  
  <p><strong>Note:</strong> I was able to fix the issue by manually editing the project file and adding a reference to <code>My Company\Common</code>. But I'd still like to know why this is happening - is it a bug in VS?</p>
