.NET - Implementing INotifyPropertyChanged

To implement the INotifyPropertyChanged interface on a business object:

• Implement the interface System.ComponentModel.INotifyPropertyChanged,
• Add a method like this:
  

  private void NotifyPropertyChanged([CallerMemberName]string propertyName = null) =>
    PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
  

• Use this method in every setter that must notify:
  

  NotifyPropertyChanged();
