• Code used in the live coding demo at DotNext

  • 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. It covers debugging, testing and simple generator code.
  • https://github.com/TessenR/BestPracticesSourceGeneratorsDemo
    • A demo focused on useful approaches to source generators' problems such as decresing their work time, producing diagnostics and configuration options.
