Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have heard of similar issue and it was caused by referencing different namespace, which is quite similar in its name. Instead of using System.Web.Mvc.Routing.Constraints; they brought in using System.Web.Http.Routing.Constraints namespace in the RouteConfig class. Could you check whether this is the same case?
