title: NuGet packing same dll twice in different folders: Cannot add part for the specified URI because it is already in the package
body: <p>I have the following two lines in my nuspec which result in the error:</p>
  
  <blockquote>
    <p>Cannot add part for the specified URI because it is already in the package.</p>
  </blockquote>
  
  <p>Here's the code in the nuspec:</p>
  
  <pre><code>        &lt;file src="bin\release\*.dll" target="lib" /&gt;
          &lt;file src="..\myProj\bin\release\*.dll" target="tools" /&gt;
  </code></pre>
  
  <p>Any thoughts on how I can get the same dlls into both targets?  I'm using VSTS to do the nuget packaging.  (I wasn't able to find any similar questions.)</p>
