title: DLL reference not copying into project bin
body: <p><strong><em>Project A</em></strong> references <strong><em>Project B</em></strong>, and <strong><em>Project B</em></strong> references an external DDL (restored using NuGet).  The DLL should get copied into <strong><em>Project A</em></strong>'s bin folder (along with <strong><em>Project B</em></strong>'s DLL):</p>

  <p>In my case, when running <strong><em>Project A</em></strong>, I get the following exception thrown:</p>
  
  <blockquote>
    <p>Could not load file or assembly 'PostSharp, Version=3.2.18.0,
    Culture=neutral, PublicKeyToken=b13fd38b8f9c99d7' or one of its
    dependencies. The system cannot find the file specified.</p>
  </blockquote>
  
  <p>The DLL is not being copied into <strong><em>Project A</em></strong>'s bin.  All other external references from <strong><em>Project B</em></strong> are being copied across just fine, which is what is confusing for me.</p>
  
  <p><code>Copy Local</code> is set to true for all references involved.  Example:</p>

  <p>How do I do this?  </p>
  
  <p>Note: Using Visual Studio 2013.</p>
