title: TFS build unable to find some NuGet package versions
body: <p>The packages restore fine on the developer PC and using Visual Studio on the build server. When performing an automated build using TFS, however, many of the packages fail with a messages like these:</p>
  
  <pre><code>WARNING: Unable to find version '5.0.4' of package 'Newtonsoft.Json'.
  WARNING: Unable to find version '1.2.2' of package 'Microsoft.Net.Compilers'.
  </code></pre>
  
  <p>Other packages work fine:</p>
  
  <pre><code>Added package 'WebGrease.1.5.2' to folder 'E:\d\w\50\s\NHXS.Web.RemittanceManager\packages'
  </code></pre>
  
  <p>I tried using <code>-verbosity detailed</code> to get more information, but it didn't help. I know some people have had success by updating the NuGet config to use version 3 of the NuGet API, but given that some of the packages work - it seems like this wouldn't be the issue. (And I don't want to break a production build server for other users). Is there a way to get more information on the failures?</p>
