title: System.Net.Http.Formatting missing in some machines(xml) but works in other (dll)
body: <p>The best way to include System.Net.Http.Formatting might be through nuget. But when a developer sees it in the default Assemblies section in reference manager then they just add it, expecting all developers to have it installed by default. But to our surprise, some developer machines did not have this dll.</p>
  
  <p>All developers have the correct folder where this dlls is found
  "C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies\"
  Some developers just have XML files and others have dlls in it, even though the file names are the same.</p>
  
  <p>Why are dlls missing in some machines?</p>
