title: Visual studio 2015 nuget package not restoring
body: <p>I've got a project with multiple nuget projects, when I opened this project with visual studio 2015 I did a nuget restore, but all packages references are still broken. In the packages folder, all the packages have been downloaded. How can I restore the packages? It is important that the versions currently defined stay the same and don't upgrade the packages.</p>

  <p>If I unload my project, the references seem good, the package versions match:</p>
  
  <pre><code>&lt;Reference Include="Dapper"&gt;
    &lt;HintPath&gt;..\packages\Dapper.1.42\lib\net45\Dapper.dll&lt;/HintPath&gt;
  &lt;/Reference&gt;
  &lt;Reference Include="EasyNetQ"&gt;
    &lt;HintPath&gt;..\packages\EasyNetQ.0.49.3.390\lib\net40\EasyNetQ.dll&lt;/HintPath&gt;
  &lt;/Reference&gt;
  &lt;Reference Include="FluentScheduler"&gt;
    &lt;HintPath&gt;..\packages\FluentScheduler.3.1.45\lib\net40\FluentScheduler.dll&lt;/HintPath&gt;
  &lt;/Reference&gt;
  &lt;Reference Include="Newtonsoft.Json"&gt;
    &lt;HintPath&gt;..\packages\Newtonsoft.Json.6.0.4\lib\net45\Newtonsoft.Json.dll&lt;/HintPath&gt;
  &lt;/Reference&gt;
