Example:

[Route("product/{name}")]
[RouteDefault("name", "")]
[RouteConstraint("name", "^[0-9]+_”)]
public ActionResult Product(string name)
{
return View();
}

I know that you have written this a long ago, but it is still worth mentioning how to improve it.

I intially started by following your steps, but I noticed that this could be even simpler by ONLY creating a custom RouteHandler using the following code:

public class CustomRouteHandler : IRouteHandler {

public IHttpHandler GetHttpHandler(RequestContext requestContext) {
RouteData routeData = requestContext.RouteData;
routeData.Values.Add(”controller”, GetControllerName(routeData));
return new MvcHandler(requestContext);
}

}

And use the following with your RouteMap ( on application start)

routes.Add(
“Custom”,
new Route (
“{useCaseNoun}/{useCaseVerb}/{action}/{id}”,
new RouteValueDictionary(new {action = “Index”, Id = “”}),
new CustomRouteHandler()
)
);
