ASP.NET MVC redirection Action to Default?

Question

I have a action on my controller (controller name is 'makemagic') called 'dosomething' that takes a nullable int and then returns the view 'dosomething.aspx'. At least this is what I am trying to do. Seems no matter I get routed to the Default() view.

public ActionResult dosomething(int? id)
{       
  var model = // business logic here to fetch model from DB
  return View("dosomething", model);
}

There is a /Views/makemagic/dosomething.aspx file that has the Inherits System.Web.Mvc.ViewPage

Do I need to do something to my routes? I have just the 'stock' default routes in my global.aspx.cs file;

public static void RegisterRoutes(RouteCollection routes)
{
      routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

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

}

I am calling the action via a href like this in another page;

<a href="/makemagic/dosomething/25">Click Me!</a>

Seriously driving me nutso. Any suggestions on how to troubleshoot this? I attempted to debug break on my route definitions and seems a break there doesn't happen as one would expect.

Change it so the parameter isn't nullable so it will match the default route, or change the name to something other than id and supply it as a query parameter. An example of the latter would be:

public ActionResult dosomething(int? foo)
{       
  var model = // business logic here to fetch model from DB
  return View("dosomething", model);
}

<a href="/makemagic/dosomething?foo=25">Click me</a>

The it will work with the default routing implementation. Alternatively, you could do something that would distinguish it from the default route and then you would be able to have a route for it and not have to use query parameters.

routes.MapRoute(
        "Default",                                     // Route name
        "{controller}/{action}/foo/{id}",              // URL with parameters
        new { controller = "makemagic", action = "dosomething", id = "" }  // Parameter defaults
);

<a href="/makemagic/dosomething/foo/25">Click Me!</a>
