UWP App GpioController.GetDefault() always returns null

What can be the reason that in my App GpioController.GetDefault() always returns null? The app is running on a RPI3b (as other Apps have done before.... never ran into this?!)
var gpioController = GpioController.GetDefault();
// gpio controller is null ... why?!
ServiceContainer.Instance.Register(new IO(gpioController));;

Found the issue. It was in Windows IoT configuration itself. There is a "default controller driver" in the devices tab. It was set to a DMA driver. Changing it to "Inbox driver" and rebooting the Pi solved the problem.

If you want to use the DMA driver which offers better performances, you need to activate/declare it to the API before querying the GpioControleler
// This needs the following capabilities
// <iot:Capability Name="lowLevelDevices" />
// <DeviceCapability Name="109b86ad-f53d-4b76-aa5f-821e2ddf2141"/>
if (LightningProvider.IsLightningEnabled)
{
LowLevelDevicesController.DefaultProvider = LightningProvider.GetAggregateProvider();
}
var gpioController = GpioController.GetDefault();
// gpioController is valid
See Lightning Providers
