title: TFS 2013 Build - Newtonsoft.Json - Visual Studio 2015
body: <p><strong>Update:</strong>
  So, I logged on to the server and opened the project with VS 2013. I clicked "enable nuget package restore" on the solution context menu. Now, it builds on the server. The problem is, I don't know how to do the same thing in VS 2015. There is no right-click menu. I have already enabled "allow automatic package restore" in Options.
  -End update</p>
  
  <p>I have a project in Visual Studio 2015. I can build and run it successfully on my local machine. It uses Newtonsoft.Json (JSON.net) which it obtains from Nuget. When I check in, and my continuous integration build runs on the build server, it throws an exception that it cannot locate the JSON.net assemblies:</p>
  
  <pre><code>The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?)
  
  C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets (1605): Could not resolve this reference. Could not locate the assembly "Newtonsoft.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed, processorArchitecture=MSIL". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.
  </code></pre>
  
  <p>I have looked all over to see what is causing the Nuget package to fail. Is it because I am using Visual Studio 2015? Is Nuget jacked up?</p>
  
  <p>Has anyone experienced this issue?</p>
