Question

I can write such beatiful straightforward code:

 public int Delta { get; private set; }

Now I want to add just one call OnPropertyChanged("Delta");

This is the only way I know how to do that:

public int Delta { get { return _delta; } private set
{
    _delta = value; OnPropertyChanged("Delta"); }
}
private int _delta;

It’s too much extra-code! Why should I introduce field in this case? Can you make this code shorter? I would like to have something like that, but it doesn’t work:

 public int Delta { get; private set { OnPropertyChanged("Delta"); } }

No you cannot do this with auto-properties. Auto-properties are meant to be short hand syntax for a property over a field. They have virtually no other capabilities. Any custom code execution requires a full fledged property.
