How to detect screen orientation
I am trying differenciate between the device being in Landscape or Portrait mode. 180° rotations don't matter to me, just which side is longer.
I have tried
SimpleOrientation OReading = SimpleOrientationSensor.GetDefault().GetCurrentOrientation();
if(OReading == SimpleOrientation.NotRotated || OReading == SimpleOrientation.Rotated180DegreesCounterclockwise)
ApplicationData.Current.LocalSettings.Values["Orientation"] = "Landscape";
if (OReading == SimpleOrientation.Rotated90DegreesCounterclockwise || OReading == SimpleOrientation.Rotated270DegreesCounterclockwise)
ApplicationData.Current.LocalSettings.Values["Orientation"] = "Portrait";
but the first line already throws a NullReferenceException. What would be the correct way to do this?
I have a .NET component that could technically also perform this, but I would prefer to do it in UWP if possible.
Note that I am not running in a simulator, but launching the App on a device that supports rotation.
I actually don't need the sensor data though, I just want to know how the screen orientation is, which can be different from the sensor data.
Edit:
public async void ChangedAsync(AppResourceGroupInfoWatcher sender, AppResourceGroupInfoWatcherExecutionStateChangedEventArgs args)
{
DisplayInformation current = DisplayInformation.GetForCurrentView();
This also does not work, and in UWP it gives me the crash
Windows.Graphics.Display: GetForCurrentView must be called on a thread that is associated with a CoreWindow.
The function is getting called by an AppResourceGroupInfoWatcher.
I am using:
using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using System.Threading.Tasks;
using Windows.ApplicationModel;
using Windows.Foundation;
using Windows.Foundation.Metadata;
using Windows.Graphics.Display;

This should work.
bool isInLandscapeMode =
Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().Orientation ==
Windows.UI.ViewManagement.ApplicationViewOrientation.Landscape;
ApplicationData.Current.LocalSettings.Values["Orientation"] = isInLandscapeMode ?
"Landscape" : "Portrait";
