You create a new ASP.NET MVC 2 Web application.
The following default routes are created in the Global.asax.cs file. (Line numbers are included for reference only.)

01 public static void RegisterRoutes(RouteCollection routes)
02 {
03 routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);
05 routes.MapRoute(“Default”, “{controller}/{action}/{id}”, new {controller = “Home”, action = “Index”, id = “”});
06 }

You implement a controller named HomeController that includes methods with the following signatures.

public ActionResult About()
public ActionResult Index()
public ActionResult Details(int id)

You need to ensure that the About action is invoked when the root URL of the site is accessed.
