title: Packaging nuget package on VSTS 'Newtonsoft.Json' already has a dependency defined for 'NETStandard.Library'
body: <p>Packaging a build use Nuget Packager in VSTS and i get the error:</p>
  <h2>[error]'Newtonsoft.Json' already has a dependency defined for 'NETStandard.Library'.</h2>
  <p>Most of the hints that solves this involves updating nuget, but since I am building on Team Services I can't really do this.</p>
