Defining a to-do list item

We will start off by creating a TodoItem class, which represents a single item on the list. This is a simple Plain Old CLR Object (POCO) class, where CLR stands for Common Language Runtime. In other words, this is a .NET class without any dependencies on third-party assemblies. To create the class, follow these steps:

1. In the .NET Standard library project, create a folder called Models.
2. Add a class called TodoItem.cs to that folder and enter the following code:

using System;

namespace DoToo.Models
{
    public class TodoItem
    {
        public int Id { get; set; }
        public string Title { get; set; }
        public bool Completed { get; set; }
        public DateTime Due { get; set; }
    }
}

This code is pretty self-explanatory; it's a simple POCO class that only contains properties and no logic. We have a Title property that describes what we want to be done, a flag (Completed) that determines whether the to-do list item is completed, a Due date for when we expect it to be done, and a unique id class that we will need later on for the database.
