when I start a game with the simulator rotated to portrait mode, I get...
GraphicsDevice.PresentationParameters.BackBuffer W/H = (1920, 1200)
GraphicsDevice.Viewport = (0,0, 1920,1200)
MyGame.instance.Window.ClientBounds = (1200 , 1920)
MyGame.instance.Window.CurrentOrientation = PortraitDown
shouldn't all values be 1200,1920 ?
(I've been able to reproduce this problem in a Surface RT with 8.1, so I don't think it's a simulator problem)
edit: the values seem to be always valid after the device is rotated
