static routing returning 404? - asp.net

Question

I'm trying to create a static route as follows:
public static void RegisterRoutes(RouteCollection routes) {
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Hire",
url: "Hire/{gender}",
defaults: new { controller = "Hire", action = "Index" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
however, when I try access /Hire/Female, for instance, IIS throws a 404 error, as I was reading about routing I noticed routes are usually written as {controller}/{action}/{something}, is it mandatory to have {controller} and {action} on my route?
here's the code for the controller:
public class HireController : Controller
{
[HttpGet]
public ActionResult Index(string gender)
{
return View();
}
}
and I have a file named /Views/Hire/Index.cshtml
what I was trying to achieve is to route requests from /Hire/Male and /Hire/Female to the Index action of my HireController but I have the feeling I'm forgetting something since I've tried in different ways and always have a 404 returned
Update 1
I installed the RouteDebugger from http://www.codeproject.com/Articles/299531/Custom-routes-for-MVC-Application and it just shows the "basic" routes from MVC ({resource}.axd/{*pathInfo} and {controller}/{action}/{id}), it doesn't show the route I mapped

Answer 1

It turns out I added the RegisterRoutes method in the wrong location, I thought I had to include that method inside Global.asax, I guess prior to MVC4 the Global.asax was the right location, however, on MVC4 I have to map the routes using the file located in /App_Start/RouteConfig.cs
