Crash When Oculus Rift S is connected

[jacobh12349]

My wpf app isn't used for vr, but when I open a wpf app while my oculus rift s vr headset is connected to my computer, the wpf app crashes with this exception message, I think the wpf app is thinking the oculus rift controllers are a stylus, and it crashes because of that for some reason.

Exception thrown: 'System.InvalidCastException' in PresentationCore.dll
System.InvalidCastException: Interface not registered

@jacobh12349 Could you try enable the WMPOINTER by the code:

        public App()
        {
            AppContext.SetSwitch("Switch.System.Windows.Input.Stylus.EnablePointerSupport", true);
        }

From your message at MS.Win32.Penimc.UnsafeNativeMethods.CreatePimcManager(), I can know it can not find the PenImc COM in your drives.

And the PenImc can be bypassed by enable the WMPOINTER message.

[jacobh12349]

AppContext.SetSwitch("Switch.System.Windows.Input.Stylus.EnablePointerSupport", true);

I don't want my app to support the rift controllers though, i just have my wpf app running in the background.
