This is my code to lock the application orientation, which you may find useful.

protected override void OnNavigatedTo(NavigationEventArgs e)
{
settings = new AppSettings();

bool locked = settings.OrientationLockSetting;
bool useAccent = settings.UseThemeColorSetting;

SetOrientation(locked);
SetAccent(useAccent);
base.OnNavigatedTo(e);
}
private void SetOrientation(bool locked)
{
this.SupportedOrientations = locked ? SupportedPageOrientation.Portrait : SupportedPageOrientation.PortraitOrLandscape;
}
