title: Namespace could not be found - building using TFS
body: <p>I have trouble with TFS. It won't build my project because</p>
  
  <blockquote>
    <p>The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?)</p>
  </blockquote>
  
  <p>I tried adding it via nuget but still I am getting this error. I have other projects which work fine when i add this dll via nuget. Also, a local build of this project is successful. I created a new folder inside the solution and then placed the dll in it and I referenced it. </p>
