I faced the same problem. Basically the problem is using different version of System.Web.Mvc. So the best thing you should the open Tools > Nuget Package Manager > Manage Nuget Packages for Solution. You can probably see System.Web.Mvc on the Cosolidate tab. Upgrade or downgrade would be the best option. If you use the latest .Net framework, which is currently .Net 4.6.1, you should upgrade the all System.Web.Mvc versions to 5.2.4.0. Good luck!
