What are auto-implemented properties, and what does the compiler generate behind the scenes for one?

An auto-property (`public string Name { get; set; }`) lets you declare a property without writing an explicit backing field or accessor bodies — the compiler automatically generates a hidden private backing field and simple get/set accessor implementations for you.

public class Person {
  public string Name { get; set; } = string.Empty; // compiler generates the backing field automatically
  public int Age { get; init; } // init-only: settable only during object initialization
}
