Answer 1

In Windows Phone 8.1, We can use BottomAppBar to add App Bar. Usually we use CommandBar to create basic BottomAppBar. CommandBar contains two collection: PrimaryCommands and SecondaryCommands, It's similar with shell:ApplicationBar.Buttons and shell:ApplicationBar.MenuItems in Windows Phone 8.

Read this demo please, we create a CommandBar with two buttons: ZoomOut and ZoomIn, and two menuItem:Test01 and Test02 :

Edit: Now the code is correct!
