title: Assembly referenced in csproj is not copied to output directory
body: <pre><code>&lt;ItemGroup&gt;
      &lt;Reference Include="Microsoft.WindowsAzure.Configuration"&gt;
          &lt;HintPath&gt;..\Microsoft.WindowsAzure.Configuration.dll&lt;/HintPath&gt;
          &lt;Private&gt;true&lt;/Private&gt;
      &lt;/Reference&gt;
      &lt;Reference Include="Microsoft.WindowsAzure.Storage"&gt;
          &lt;HintPath&gt;..\Microsoft.WindowsAzure.Storage.dll&lt;/HintPath&gt;
          &lt;Private&gt;true&lt;/Private&gt;
      &lt;/Reference&gt;
  &lt;/ItemGroup&gt;
  </code></pre>
  
  <p>The reason is that is because I don't want <a href="https://stackoverflow.com/questions/43837638/how-to-get-net-core-projects-to-copy-nuget-references-to-build-output">all assemblies from all .NET Core to get copied</a> to my output folder.</p>
  
  <p>Now setting <code>Copy Local</code> to <code>Yes</code> in Visual Studio equals to <code>&lt;Private&gt;true&lt;/Private&gt;</code> in <code>csproj</code> file.</p>
  
  <p>The problem is, these DLL files are not getting copied to the output directory. What's more irritating is that I've added the same exact line of codes to a similar project, and only one of the files is getting copied to the output.</p>
  
  <p>What can be the problem here? How do I debug this? I've made sure that these file exist and their relative path are correct.</p>
