I am using ASP.NET with VSCode. I am new to ASP and this is my first project. I created the project and created a folder called admin with an index.cshtml file in it. But when I try to access the file in the browser by typing localhost:5000/admin/, localhost:5000/admin/index and localhost:5000/admin/index.cshtml, but none of these URLs display the WebPage. Instead the browser shows that the URL could not be found in localhost:5000.

I tried to find out a solution by Googling, but found nothing. I do not want to jump into MVC just yet, as I have never worked with it.

PS: Please don't get this removed with the reason that "This question needs more research." I am a beginner and have already explained what I could have.

The way Asp.net MVC framework works is:

• Request first goes to an action and not a view (e.g. index.cshtml). Of course a lot happens before that
• Folder name is by default mapped with the name of an existing controller. So you need to have a controller named AdminController that will have to be inherited from a Microsoft.AspNetCore.Mvc.Controller
• In the admincontroller controller you need to have an action called Index
• Then your index.cshtml needs to be put either in the /Views/Admin/index.cshtml location or in the /Views/Shared/index.cshtml location

After that when you hit the Url localhost:5000/admin/index the request will go to the Action called Index in the AdminController controller. The last line of an action method is usually return View(); which will look for a cshtml page named that matches the name of the action. Which is Index in this case. So it will start to look for a index.cshtml file. That is how it will render your index.cshtml view if it is found.

Here a simple controller and action:

public class AdminController : Controller
{
    public AdminController()
    {
    }

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

Conventional routing typically used with controllers and views.You must create your views in the right location.In general, if you want to return a view for a controller action, then you need to create a subfolder in the Views folder with the same name as your controller. Within the subfolder, you must create a view with the same name as the controller action.

You can refer to the doc to understand what is mvc.

If you are using ASP.NET,you can try to create a AdminController in Controllers folder like this:

public class AdminController : Controller
{

    public ActionResult Index()
    {
        return View();
    }
}

If you are using ASP.NET Core MVC,you can try to create a AdminController in Controllers folder like this:

public class AdminController : Controller
    {
    
        public IActionResult Index()
        {
            return View();
        }
    }
