What are Automatic Properties in C# and what is their purpose?

Automatic Properties are used when no additional logic is required in the property accessors.
The declaration would look something like this:

public int SomeProperty { get; set; }

They are just syntactic sugar so you won’t need to write the following more lengthy code:

 private int _someField;
 public int SomeProperty 
 {
    get { return _someField;}
    set { _someField = value;}
 }
