public enum WTFeatures : ulong { WTFeature_2DTracking = 1uL, Geo = 4uL }
There actually is another WTFeatures constant for 3DTracking which is not exposed to the Xamarin API. It is defined as 1 << 1 which explains the gap in-between the other two flags. I recommend using our flags as we don't make any guarantees regarding the underlying values.
