The Controller is a class in the system that derives from the "Controller" class.

        
namespace MyProgram.Controllers
{
    public class MyTaskController : Controller
    {
        public ActionResult Index()
        {
            if(loggedIn == false)
                return RedirectToAction("Index", new { id = sdf });
            else
                return View();
        }
    }
}
        
        

The Model is a class in the system that does not necessarily to be derived from any class.

        using System;

        public partial class City
        {
    
            public City()
            {
                this.Users = new HashSet();
            }

            public int CityID { get; set; }
            public string City { get; set; }
            public int CountryID { get; set; }
            public int StateID { get; set; }

            public virtual Country Country { get; set; }
            public virtual State State { get; set; }
            public virtual ICollection Users { get; set; }
        }
}
        
        

The View is an html file with .chtml extension.

In a typical program, there are generally a number of Controllers written for various activities/functions and in return, these controllers use their relevant Views, partial-views, and models, View-models, to produce a meaningful functionality.
