Setting the Default Page or Route in MVC application


For convenience, we are going to tell MVC that requests to the / URL for our application should be

directed to the Index action method of the Product controller. To do this, open the Global.asax file and 

find the RegisterRoutes method. In this method, there is a call to routes.MapRoute. Change the value 

assigned to the controller property from Default to Product,

Setting the Controller for the Default Route
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Product", action = "Index", id = UrlParameter.Optional }
)
