Answer by Kyle McClellan for How to deal with nullable reference types with System.Text.Json?

Another option, for those who want to handle missing properties with meaningful exceptions:

using System;public class Car{    private string? name;    private int? year;    public string Name    {        get => this.name ?? throw new InvalidOperationException($"{nameof(this.Name)} was not set.");        set => this.name = value;    }    public int Year    {        get => this.year ?? throw new InvalidOperationException($"{nameof(this.Year)} was not set.");        set => this.year = value;    }}
