can I omit field creation if I need custom getter/setter?
<p>I can write such beatiful straightforward code:</p>

<pre><code> public int Delta { get; private set; }
</code></pre>

<p>Now I want to add just one call <code>OnPropertyChanged("Delta");</code></p>

<p>This is the only way I know how to do that:</p>

<pre><code>public int Delta { get { return _delta; } private set
{
    _delta = value; OnPropertyChanged("Delta"); }
}
private int _delta;
</code></pre>

<p>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:</p>

<pre><code> public int Delta { get; private set { OnPropertyChanged("Delta"); } }
</code></pre>
