c# - 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 OnLaunched. But yet when tested on a tablet the app goes back to portrait mode.

 DisplayInformation.AutoRotationPreferences = 
                     DisplayOrientations.Landscape | DisplayOrientations.LandscapeFlipped;

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

Thanks in advance.
