  • https://github.com/TessenR/NotifyPropertyChangedDemo
    • A simple demo with NotifyPropertyChanged generator focused on being as simple as possible. It adds a property changed event to all types implementing INotifyPropertyChanged interface and adds properties raising this event for all fields with names ending with *BackingField suffix.
