title: How to intercept NotifyPropertyChange event
body: <p>I just recently discovered an INotifyPropertyChange interface. I managed to implement this interface in my clss and everything works fine. However I was wondering if it is possible to intercept this event in code and fire a function
  Let's say that I have a function </p>
  
  <pre><code>DoStuff()
  </code></pre>
  
  <p>and I wan't to fire this function everytime property1, property2 or property3 changes.
  Of course I could put this function in set block in my class but this is not a good idea(I think).</p>
