Since events are non serializable, here is the way out to deal the problem when serializing model classes which have a property changed event to notify the view model classes:

[NonSerialized] private PropertyChangedEventHandler _PropertyChanged; public virtual event PropertyChangedEventHandler PropertyChanged { add { _PropertyChanged += value; } remove { _PropertyChanged -= value; } }
