Areas

Introduction#

What is area?

An area is a smaller unit in MVC application which used as a way to separate large amount of application modules into functional groups. An application can contain multiple areas which stored in Areas folder.

Each area can contain different models, controllers and views depending on requirements. To use an area, it is necessary to register the area name in RouteConfig and define route prefix for it.

Remarks#

if you want to go to this area through your default controller

      return RedirectToAction("Index","Home",new{area="areaname"});

Right click on your project folder/name and create new area and name it.

In mvc internet/empty/basic application a folder with the name of the area will be created,which will contain three different folders named controller , model and views and a class file called

            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
