Subscribe to SwapChainPanel events.
This option requires XAML application type. Unity will only receive mouse and touch events that happen on SwapChainPanel. Keyboard input is always taken from CoreWindow and is always available to Unity. You may want this input method when Unity does not occupy the whole window and there are other XAML elements besides it. In such case mouse movement outside Unity rendered area won't be seen by Unity and will not cause side effects.
