Focusing on Entry Field Each Time a ContentView View Shows

I have MyView.xaml.cs and MyView.xaml (which is a ContentView) defining MyView view.

MyView has an Entry field. How do I focus on that Entry field each time MyView is shown on screen?

Originally, I thought I could just to to MyView.xaml.cs and override OnAppearing() lifecycle method. But ContentView does not have OnAppearing().
