How to enable only landscape mode in a UWP app?

Question

I have already specified in the manifest as Landscape and LandscapeFlipped, I know this is just a preference and on top of this I\'ve added the below code in the App.xaml.cs

Answer 1

You used the right API to force the orientation in UWP app, but you can refer to the official DisplayOrientations enumeration, in the remarks part:

Applications typically use this property to translate the reading of an accelerometer or to translate the physical button events in accordance with the current screen rotation.

It means, these work but only if the device has an accelerometer, on laptop even simulator, they have no effect.

Also is there any alternative way I could test this in a simulator instead of an actual tablet/device?

No, simulator is not suitable, you can test this on Mobile or Mobile emulator.
