I the following example works fine. But if i remove the controller then it errors out.

Answer 1

Placing the following route before the default route definition will directly call the 'Thread' action in 'Thread' controller with the 'id' and 'slug' parameter.

routes.MapRoute(
    name: "Thread",
    url: "Thread/{id}/{slug}",
    defaults: new { controller = "Thread", action = "Thread", slug = UrlParameter.Optional },
    constraints: new { id = @"\d+" }
);

Then if you really want it to be like stackoverflow, and assume someone enters the id part and not the slug part,

public ActionResult Thread(int id, string slug)
{
    if(string.IsNullOrEmpty(slug)){
         slug = //Get the slug value from db with the given id
         return RedirectToRoute("Thread", new {id = id, slug = slug});
    }
    return View();
}

hope this helps.
