Assembly: System.Device (in System.Device.dll)
The movement threshold does not guarantee that events will be received at the requested threshold. The platform attempts to honor requests for a particular movement threshold, but in some cases, the events will not be raised at the requested threshold.
Note In versions of Windows prior to Windows 7, the following conditions apply:
No location events will be raised.
The following diagram represents location coordinates that the location provider (for example, a GPS device) supplies to the computer. P1, in the diagram, represents the location data included in a PositionChanged event, and P2, P3, and P4 represent points within the movement threshold. So when the location provider supplies data indicating a location at those points (P1, P2, P3, and P4), no PositionChanged events are raised, and Position returns P1. The point P5 is outside of the distance, so at that point, P:System.Device.Location.GeoLocationProvider.Location is updated and a E:System.Device.Location.GeoLocationProvider.LocationChanged event is raised.
