title: Using libraries with ASP.Net MVC 6
body: <p>I'm trying out Visual Studio 2015 Preview creating a new MVC 6 project.  I would like to add existing MVC libraries but anything I add to the project.json results in a warning in the references for ASP.Net 5.0 and/or ASP.NET Code 5.0.  In truth I haven't found any existing libraries or packages on nuget (tried DefinitelyTyped too) that will work.</p>
  
  <p>I'm guessing that with all the structure changes, especially the removal of System.Web, none of the existing libraries will work.  Can anyone confirm this or provide a way to force them to work? </p>
