hi,i'm new to routing in aspnet mvc.. i have following code: Action Controller

public ActionResult SchoolIndex()
{
    return View(SchoolRepository.GetAllSchools());
}

here is the routing

routes.MapRoute(
"School",                                              // Route name
"{controller}/{action}/{id}",                           // URL with parameters
new { controller = "School", action = "SchoolIndex", id = "" } ); // Parameter defaults

when i enter "localhost/school" in addressbar, it is giving 404 error instead it should route to my "schoolIndex" action

i have given route-name as "School" where it is used ?
