Flashlight windows phone 8 c#

Question

I am a beginner who is trying to make a flashlight app for windows phone.

I have added a single button in the XAML, and this is the c#-code:

private async void Button_Click(object sender, RoutedEventArgs e)
        {
            CameraSensorLocation camLocation = CameraSensorLocation.Back;
            IReadOnlyList<object> CameraModes;
            CameraModes = AudioVideoCaptureDevice.GetSupportedPropertyValues(camLocation, KnownCameraAudioVideoProperties.VideoTorchMode);
            if (CameraModes.ToList().Contains((UInt32)VideoTorchMode.On))
            {
                AudioVideoCaptureDevice flashDevice;
                flashDevice = await AudioVideoCaptureDevice.OpenAsync(camLocation, AudioVideoCaptureDevice.GetAvailableCaptureResolutions(camLocation).First());
                flashDevice.SetProperty(KnownCameraAudioVideoProperties.VideoTorchMode, VideoTorchMode.On);
            }
        }

Can anyone tell me what is wrong with the code?
