ScreenOrientation.AutoRotation
Description

Auto-rotates the screen as necessary toward any of the enabled orientations.

When this option is assigned to the orientation property, the screen will auto-rotate so that the bottom of the screen image points downwards. The orientations that can be used are set by the autorotateToLandscapeLeft, autorotateToLandscapeRight, autorotateToPortrait and ::autorotateToPortraitUpsideDown properties. For example, if autorotateToPortrait and ::autorotateToPortraitUpsideDown are both true but the others are false then the auto-rotation will never choose either of the landscape options even when the device is held with the long side of the screen pointing downwards.
