[c#] ASP.NET MVC 3 - redirect to another action

I want to redirect the Index action of the Home controller to another controller's action and nothing else. My code is thus:

    public void Index()
    {
        //All we want to do is redirect to the class selection page
        RedirectToAction("SelectClasses", "Registration");
    }

Right now, this just loads a 0 kB blank page and does nothing. I have a feeling it has something to do with that void return type, but I don't know what else to change it to. What's the issue here?

You will need to return the result of RedirectToAction.

Should Return ActionResult, instead of Void

return RedirectToAction("ActionName", "ControllerName");

You have to write this code instead of return View(); :

return RedirectToAction("ActionName", "ControllerName");
