Explain attribute based routing in MVC?

In ASP.NET MVC 5.0 we have a new attribute route, by using the "Route" attribute we can define the URL structure. For example, in the below code we have decorated the "GotoAbout" action with the route attribute. The route attribute says that the “GotoAbout” can be invoked using the URL structure "Users/about".

The attribute-based routing uses an attribute to define the routes. It gives you more control over the URIs in your web application. The route can be enabled in the MapMvcAttributeRoutes during the configuration process. The attribute routing can also be combined with the convention-based routing.
