How to remove a MVC Route

Hi,

I'm building my own check-out & register logic.
So for this I have my own IRouteProvider implementation and it works.
However once in a while I get things like:

Exception message: A route named 'Register' is already in the route collection. Route names must be unique.

How can I fixed this ?

public class RouteProvider : IRouteProvider
    {
        public void RegisterRoutes(RouteCollection routes)
        {

            routes.Remove(routes["CustomerMyAccount"]);
            routes.Remove(routes["CustomerInfo"]);
            routes.Remove(routes["Register"]);
            routes.Remove(routes["RegisterResult"]);


            routes.MapLocalizedRoute("CustomerMyAccount",
                "customer/myaccount",
                new { controller = "xxxCustomer", action = "MyAccount" },
                new[] { "Nop.Plugin.xxx" });
            
            routes.MapLocalizedRoute("CustomerInfo",
                "customer/info",
                new { controller = "xxxCustomer", action = "Info" },
                new[] { "Nop.Plugin.xxx" });

            routes.MapLocalizedRoute("Register",
                "register/",
                new { controller = "xxxCustomer", action = "Register" },
                new[] { "Nop.Plugin.xxx" });
            routes.MapLocalizedRoute("RegisterResult",
                "registerresult/{resultId}",
                new { controller = "xxxCustomer", action = "RegisterResult" },
                new { resultId = @"\d+" },
                new[] { "Nop.Plugin.xxx" });

        }

        public int Priority
        {
            get { return 0; }
        }
    }


What does Priority do ?

Nevermind...
Setting the priority to -1 does the trick.
(sorry)

In my case this works only on my development machine, but on the production server the plugin's routes are never called...any idea?

solved, I didn't noticed the shadow copy folder of the plugins was not cleared on application start-up!
