title: INotifyPropertyChanged and Auto-Properties
body: <p>Is there a way to use <code>INotifyPropertyChanged</code> with auto-properties? Maybe an attribute or something other, not obvious to me.</p>
  
  <pre><code>public string Demo{
      get;set;
  }
  </code></pre>
  
  <p>For me, auto-properties would be an extremely practicall thing, but almost always, I have to raise the <code>PropertyChanged</code>-event if the property value has been changed and without a mechanism to do this, auto-properties are useless for me. </p>
