title: Reference could not be added because of same name
body: <p>Since the update to VS 2013 I have the behaviour that I cannot add a reference to 2 projects with the same name. I did the following:</p>
  
  <ol>
  <li>Added 3 solution folders A, B and C.</li>
  <li>Added a project of type class library "Core" to both A and B folder.</li>
  <li>Added a project of type ConsoleApplication to folder C.</li>
  </ol>
  
  <p>The resulting structure looks like this:</p>
  
  <pre><code>Solution
   + A
     + Core
   + B
     + Core
   + C
     + ConsoleApp
  </code></pre>
  
  <p>In the project properties of A the following is entered:</p>
  
  <ul>
  <li>Assembly name: A.Core</li>
  <li>Default namespace: A.Core</li>
  </ul>
  
  <p>and in B:</p>
  
  <ul>
  <li>Assembly name: B.Core</li>
  <li>Default namespace: B.Core</li>
  </ul>
  
  <p>After I added a reference to A.Core in C.ConsoleApp and I try to reference to B.Core to the console I get the error:</p>
  
  <blockquote>
    <p>A reference to 'Core (B.Core)' could not be added. A reference to the component 'Core' already exists in the project.</p>
  </blockquote>
  
  <p>The solution was created with VS 2012 and shows this behavior since upgrade. What do I have to setup inside the console?</p>
  
  <p>Edit: I published a screencast on <a href="http://youtu.be/Fgni6iMfJ-M">Youtube</a> to explain the problem and placed a bug at <a href="https://connect.microsoft.com/VisualStudio/feedback/details/809484/bug-when-adding-references-to-projects-with-same-project-names">Microsoft-Support</a>. I still think, this is a bug.</p>
