When to use Area attribute along with controller

9y987.NET

see the below code and tell me when some one use Area attribute along with controller.

is it any kind of attribute routing for which area attribute keyword is used along with controller ?

does it mean only user with admin role can access home controller ?

[Area("Admin")]
public class HomeController : Controller
{
// GET: //
public IActionResult Index()
{
return View();
}

public IActionResult Details()
{
return View();
}
}

i got the above code from this url http://www.dotnetfunda.com/articles/show/3390/using-area-in-aspnet-core

so if i understand correctly then it means Area attribute allow to change the url? am i right ?

when we create area folder in project then it would mandatory to use area attribute on controller or action method ?

see these url which talking about area

https://www.codeproject.com/Articles/714356/Areas-in-ASP-NET-MVC

http://www.dotnettricks.com/learn/mvc/mvc-areas-with-example

the above url show how to work with area but they never use [Area("Admin")] in code.

so still it is not clear when to use [Area("Admin")] in code.

please make this area more clear for me. thanks

Nilesh u said about what is the purposes of area but u did not read my post properly because u forget to mention why we use area attribute? When we work with area then it is mandatory that we need to decorate controllers with area attribute?

Areas allow us to organize Models, Views and Controllers into separate functional sections of the application or simply separate folder. It will come handy in a large web application where managing all the Models, Views and Controllers will be a little tiresome. Each MVC area has its own folder structure which allow us to keep separate Models, Views and Controllers inside a folder.

Area is used in ASP.net MVC project for modularization i.e. when you have many modules in your web app and you want to seperate everything controllers, views, models, etc. as per the modules then you use module.

Let's say you have a school management system, then you will create area wise folders like attendance, exam, teachers, timetable, rooms, etc. and each area folder will have their own controllers, views, models, etc.
