The Evolution of C# Constructors

C# 12 introduces a new syntax to declare class constructors with Primary Constructors. That's why I thought that it's a good time to look back at the evolution of C# constructors. Starting from the most basic constructor that most of us are familiar with, to the newer variations that were added in latest the C# versions.


 Person.ts 
public class Person
{
    public long Id { get; }
    public string Name { get; }
 
    public Person(int id, string name)
    {
        Id = id;
        Name = name;
    }
}


 Person.ts 
public class Person
{
    public long Id { get; }
    public string Name { get; }
 
    public Person(int id, string name)
        => (Id, Name) = (id, name);
}


 Person.ts 
public class Person
{
    public required long Id { get; init; }
    public required string Name { get; init; }
}


 Person.ts 
public class Person(long id, string name)
{
    public long Id { get; } = id;
    public string Name { get; } = name;
}
