This is the use of AutoDeconstruct in Program.cs

// See https://aka.ms/new-console-template for more information
Console.WriteLine("Hello, World!");
var p = new Person();
p.FirstName = "Test";
p.LastName = "Ignat";
var (_, l, _ ) = p;
Console.WriteLine($"Last name is {l}");

This is the use of AutoDeconstruct in Person.cs

// See https://aka.ms/new-console-template for more information
using AutoDeconstruct;

public class Person
{
    public string? FirstName { get; set; }
    public string? LastName { get; set; }
    public string? Title { get; set; }
}

[NoAutoDeconstruct]
public class TestPerson
{
    public string? FirstName { get; set; }
    public string? LastName { get; set; }
    public string? Title { get; set; }

}
