title: Enable NuGet Package Restore on Visual Studio 2013
body: <p>I'm following <a href="https://developers.google.com/+/quickstart/csharp">this easy tutorial</a> to start coding with the Google+ API in C#. However, I've been stuck for hours on Step 3, where the first substeps are:</p>
  
  <ol>
  <li>In Visual Studio, click Project > Enable NuGet Package Restore > answer Yes in the dialog.</li>
  <li>Right-click on the gplus-quickstart-csharp project and select Manage NuGet Packages.</li>
  <li>Click Restore on the Manage NuGet Packages window. This will install the Google API Client libraries.</li>
  </ol>
  
  <p>When I click on Projet, there is no option "Enable NuGet Package Restore". </p>
  
  <p>There <em>is</em> a Manage Nuget Packages option, but no Restore button or option whatsoever.</p>
  
  <p>The project doesn't build and gives me the error: </p>
  
  <blockquote>
    <p>Error 1   This project references NuGet package(s) that are missing on
    this computer. Enable NuGet Package Restore to download them.  For
    more information, see <a href="http://go.microsoft.com/fwlink/?LinkID=322105">http://go.microsoft.com/fwlink/?LinkID=322105</a>.
    The missing file is
    C:\Users\Documents\google+\gplus-quickstart-csharp\.nuget\NuGet.targets. C:\Users\Documents\google+\gplus-quickstart-csharp\gplus-quickstart-csharp\gplus-quickstart-csharp.csproj   201 5   gplus-quickstart-csharp</p>
  </blockquote>
  
  <p>I went on the microsoft website and it only redirects to the NuGet documentation where I didn't find anything that works. I tried the following commands (described in the examples):</p>
  
  <ul>
  <li>D:\projects\contoso> nuget.exe restore</li>
  <li>D:\projects\contoso> nuget.exe restore contoso.sln</li>
  <li>D:\projects> nuget.exe restore contoso</li>
  </ul>
  
  <p>but to no avail. And yes, NuGet is installed. Any ideas? Thanks!</p>
