title: Referenced Dll's not found in Team Foundation Service (or: nuget packages not available on other pc)
body: <p>when I create a build for the Team Foundation Service, I get all kind of reference dll's not found exceptions.</p>
  
  <p>These references are added by nugget packages.</p>
  
  <p>I've added the 'package restore' option on the solution which added 3 files in a .NuGet folder.</p>
  
  <p>EDIT</p>
  
  <p>When i got the solution from TFS on another pc, i got the same errors (missing dll's), so it's not only the TFS build service having problems.</p>
  
  <p>The missing dll's are are missing files from installed nuget packages (some are part of the default VS template, Unity was a package i added later), which (the packages) are added on the first pc, but then are missing on the next pc (that's why i added the 'or' in the title of this question)</p>
  
  <p>How can i get the Nuget added files on pc2 too?</p>
