UWP, Inject touch events Exception

Question

Using InputInjector and InjectedInputTouchInfo to programmatically send touch events in windows 10 1709. I have been able to send mouse events using InjectMouseInput. But When I tried to inject touch events, I am getting exception. Code tried is same as provided by MSDN page

inputInjector.InjectTouchInput(
            new List<InjectedInputTouchInfo> {
            new InjectedInputTouchInfo {
                Contact = new InjectedInputRectangle
                {
                    Top = 50,
                    Bottom = 50,
                    Left = 40,
                    Right = 40
                },
                PointerInfo = new InjectedInputPointerInfo {
                    PixelLocation = new InjectedInputPoint {
                        PositionX = 40, PositionY = 50
                    },
                    PointerOptions = InjectedInputPointerOptions.PointerUp,
                    PointerId = 1,
                },
                Pressure = 0.0,
                TouchParameters = 
                InjectedInputTouchParameters.Pressure | 
                InjectedInputTouchParameters.Contact
            }
        });

executed this code gives exception.

{System.ArgumentException: Value does not fall within the expected range. at Windows.UI.Input.Preview.Injection.InputInjector.InjectTouchInput(IEnumerable`1 input) }

It seems it is issue with an update of Windows, Visual Studio or SDK. Your code seem correct.
