Screen.orientation returns "Autorotation" instead of the actual orientation when running a UWP app on Windows 10. Once the Surface device is rotated during runtime, the correct orientation is returned.

Repro steps:
Build the attached sample for Windows Store (Universal 10) and run it on a Windows 10 tablet. In the top left, you will see a label saying "AutoRotation". This label is directly reading Screen.orientation.

If you rotate the Surface tablet now (assuming this is enabled in the system settings), the label will be updated to the correct orientation.
