What is the difference between ObservableCollection and INotifyPropertyChanged?

Question

I am confused about how ObservableCollection and INotifyPropertyChanged works.

I have this code:

Payments = new ObservableC         


        

Answer 1

An ObservableCollection notifies its binder, with for example when something is added/deleted to the collection itself.

What you're doing in the second example however, is notifying the binder that the collection has been replaced by a new collection (something that the ObservableCollection does not do itself, if you do new ObservableCollection - there you lose the binding).
