title: How to notify all properties of the view model has changed
body: <p>In MVVM pattern, how to notify all properties of the view model has changed? I don' t want to call all notifypropertychanged event of all properties. </p>
  
  <p>I have an entity class and in view model I wrote all of the public fields of the entity as public properties. I want to rebind new entity and just write a single line of code to notify that all properties has changed?</p>
  
  <p>Thanks for your help.</p>
