wpf - 如何将“自定义事件”从“wpf”迁移到“winui”？

Question

wpf到​​winui迁移如何

public static readonly RoutedEvent SelectedEvent = EventManager.RegisterRoutedEvent("Selected", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(PointControl));
public event RoutedEventHandler Selected { add { AddHandler(SelectedEvent, value); } remove { RemoveHandler(SelectedEvent, value); } }

自定义路由事件？

找不到EventManager
