I can’t help myself, I love Expression-Bodied Members from C# 6! Combined with other powerful C# features it took this code: public void OnPropertyChanged(string name) { var changed = PropertyChanged; if(changed == null) return; changed(this, new PropertyChangedEventArgs(name)); } to this: public void OnPropertyChanged(string name)=> PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name)); This is …

It also benefits from being really …
