    Error 1 'System.Web.Routing.RouteCollection' does not contain a definition for 'MapMvcAttributeRoutes' and no extension method 'MapMvcAttributeRoutes' accepting a first argument of type 'System.Web.Routing.RouteCollection' could be found (are you missing a using directive or an assembly reference?)

    1. Try adding 'System.Web.Http' and 'System.Web.Mvc' namespace reference in RouteConfig.cs.
    If they are not available then Add Reference of 'System.Web.Http and System.Web.Http.WebHost.dll' first to your solution and then try above line.
    2. You had called routes.MapMvcAttributeRoutes(); i.e. you haven't passed RouteCollection/Routes as its argument, thats why you are getting this error.
    It must be MapMvcAttributeRoutes(RouteCollection).
    Please see its definition over here:

    I'm not sure about this but as per error details the method which you called as "MapMvcAttributeRoutes" is not part of this class "System.Web.Routing.RouteCollection" may be you missed to add references for this or the method it self is not available, request you to recheck whether the class contains that method or not.
