title: .net 4.5.2 reference not recognized
body: <p>I have inherited a MVC 3 project where the previous developer developed using VS2010. I am using VS2015 Enterprise. I am in the process of upgrading the application to .net framework 4.5.2.</p>
  
  <p>I have updated references but am still running into the following error:</p>
  
  <p>The type or namespace 'RoleProvider' could not be found (are you missing a using directive or an assembly reference". I have the current System.Web.ApplicationServices reference. </p>
  
  <p>Any ideas of a step I may be missing? Thanks</p>
