Bits of .NET

Want immutable objects but constructors with 10 parameters are ugly? Use init accessors.

Old Way – Constructor Overload Hell:

public class Person
{
    public string Name { get; }
    public int Age { get; }
    public string Email { get; }

    public Person(string name, int age, string email)
    {
        Name = name;
        Age = age;
        Email = email;
    }
}

var person = new Person("John", 30, "john@example.com");

New Way – init Accessors:

public class Person
{
    public string Name { get; init; }
    public int Age { get; init; }
    public string Email { get; init; }
}

var person = new Person 
{ 
    Name = "John",
    Age = 30,
    Email = "john@example.com"
};

person.Name = "Jane";  // ❌ Compiler error - can't change after init

Benefits: Object initialization syntax, but properties are immutable after construction. No constructor needed!
