The Device.Screen object gives you access to all information and functionality of the screen.

var height = View.Root.ActualHeight;

The following shows the configurations necessary for dynamic orientation (supporting both).

<uap:Rotation Preference="landscapeFlipped" />
If you app supports both portrait and landscape orientation, you can find the current orientation of the device for processing in your app using:
// Landscape logic...
public Task OnOrientationChanged()
var newOrientation = Device.Screen.Orientation;
