DeviceScaleChangeEventArgs>This event is raised only on Windows 8.1 or later, when the application has per-monitor DPI awareness.
On platform targets where the DpiChanged event is also available, this event is raised after DpiChanged. If you want to prevent auto-scaling by DpiChanged, subscribe DpiChanged as well (or override OnDpiChanged), and set Cancel in the event arguments to . In contrast, the arguments of the DeviceScaleChanged event cannot be canceled, but this event does not do anything automatically if not subscribed.
Unlike in the Form.OnGetDpiScaledSize event arguments, the DeviceScaleChangedEventArgs.SuggestedBounds property contains a scaled size even if AutoScaleMode is None. The suggested bounds still can be ignored by the subscriber of the event.
