## Overview

This is an ASP.NET Core MVC task planner: users view tasks, add them with a due time and importance, and update or delete them. Requests enter through the Home controller, which delegates task operations to a service; the service uses Entity Framework to persist and retrieve task records, and the index view presents the task list. Task records also derive a human-readable time remaining value. The view implementation and database configuration were not sampled, so their detailed behavior is not represented.

Main entry points: [`Controllers/HomeController.cs`](https://github.com/lisyarakirovskiy/exam/blob/master/Controllers/HomeController.cs) (Home controller), [`Views/Home/Index.cshtml`](https://github.com/lisyarakirovskiy/exam/blob/master/Views/Home/Index.cshtml) (Task list view), [`Services/TaskService.cs`](https://github.com/lisyarakirovskiy/exam/blob/master/Services/TaskService.cs) (Task service), [`Program.cs`](https://github.com/lisyarakirovskiy/exam/blob/master/Program.cs) (Application startup)
