Attribute routes aid the same inline syntax as conventional routes to specify optional parameters, default values, and constraints.
The route names give the route a logical identify. The named route may be used for URL generation. Using a named route simplifies URL creation in the event the purchasing of routes could make URL generation complex. Route names has to be one of a kind software vast.

By Conference (and default) the very first URL maps to your ProductController class using an action named Index. The next URL maps to your ProductController class with and motion named Particulars. As we will see, MVC Routing assists summary URLs faraway from physical documents which by default maps to Controller/Action method pairs by default.
