Create Class with Method

public static void AddNewAppBarinPage(Page myPage)
{
   CommandBar cbar = new CommandBar { ClosedDisplayMode = AppBarClosedDisplayMode.Minimal };
   AppBarButton appBarButton = new AppBarButton { Label = "Audio" };
   cbar.PrimaryCommands.Add(appBarButton);
   myPage.BottomAppBar = cbar;
}

use in Page:

AppBarCustom.AddNewAppBarinPage(this);
