Automatic Implemented Properties in C#

Auto-implemented properties were introduced in C# 3.0 to make developers lives simpler by avoiding default implementation of properties. 

Let's say, we create a public property called Model. The default implementation of the property looks like Listing 1. 

public partial class Car
{
    private string model; 

    public string Model
    {
        get { return model; }
        set { model = value; }
    }
}

Listing 1

The same code can be replaced with Listing 2. 

 public string Model { get; set; } 

Listing 2

Listing 2 is automatic implemented property example. You must implement both getter and setter on a property. The auto-implemented properties code basically tell compiler that this property is default property implementation and compiler writes code that is needed to do exactly same what Listing 1 does.

So you would think what do you need the automatic properties? Well, they make your code look cleaner and faster.
