    <summary>Supplies location data that is based on latitude and longitude coordinates.</summary>
    <remarks>
      <format type="text/markdown"><![CDATA[

## Remarks
 The <xref:System.Device.Location.GeoCoordinateWatcher> class supplies coordinate-based location data from the current location provider. The current location provider is prioritized as the highest on the computer, based on a number of factors, such as the age and accuracy of the data from all providers, the accuracy requested by location applications, and the power consumption and performance impact associated with the location provider. The current location provider might change over time, for instance, when a GPS device loses its satellite signal indoors and a Wi-Fi triangulation provider becomes the most accurate provider on the computer.

 To begin accessing location data, create a <xref:System.Device.Location.GeoCoordinateWatcher> and call <xref:System.Device.Location.GeoCoordinateWatcher.Start*> or <xref:System.Device.Location.GeoCoordinateWatcher.TryStart*> to initiate the acquisition of data from the current location provider.

 The <xref:System.Device.Location.GeoCoordinateWatcher.Status> property can be checked to determine if data is available. If data is available, you can get the location one time from the <xref:System.Device.Location.GeoCoordinateWatcher.Position*> property, or receive continuous location updates by handling the <xref:System.Device.Location.GeoCoordinateWatcher.PositionChanged> event.

 The <xref:System.Device.Location.GeoCoordinateWatcher.Permission*>, <xref:System.Device.Location.GeoCoordinateWatcher.Status*>, and <xref:System.Device.Location.GeoCoordinateWatcher.Position*> properties support <xref:System.ComponentModel.INotifyPropertyChanged>, so that an application can data-bind to these properties.

 In Windows 7, all the <xref:System.Device.Location> classes are fully functional if a location provider is installed and able to resolve the computer's location.

> [!NOTE]
>  On Windows 7 Starter Edition, the only supported location provider is the Default Location Provider in Control Panel, and an add-in must be installed to specify latitude and longitude.

 **Note** In versions of Windows prior to Windows 7, the following conditions apply:

- All <xref:System.Device.Location> objects that have constructors can be created, but the <xref:System.Device.Location.GeoCoordinateWatcher.Status> property will always have the value <xref:System.Device.Location.GeoPositionStatus.Disabled>.

- The location indicated by the <xref:System.Device.Location.GeoPosition`1.Location> property of <xref:System.Device.Location.GeoCoordinateWatcher.Position*> will always be <xref:System.Device.Location.GeoCoordinate.Unknown>.

- No location events will be raised.



## Examples
 The following program shows how to create a <xref:System.Device.Location.GeoCoordinateWatcher> and start acquiring data by using an initialization timeout. The code then prints the coordinates of the location, if known.

        <remarks>

## Remarks
 The default movement threshold is zero, which means that any change in location detected by the current location provider causes a <xref:System.Device.Location.GeoCoordinateWatcher.PositionChanged> event and an update in the <xref:System.Device.Location.GeoCoordinateWatcher.Position> property.

> [!NOTE]
>  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:

- All <xref:System.Device.Location> objects that have constructors can be created, but the <xref:System.Device.Location.GeoCoordinateWatcher.Status> property will always have the value <xref:System.Device.Location.GeoPositionStatus.Disabled>.

- The location indicated by the <xref:System.Device.Location.GeoPosition`1.Location> property of <xref:System.Device.Location.GeoCoordinateWatcher.Position*> will always be <xref:System.Device.Location.GeoCoordinate.Unknown>.

- 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 <xref:System.Device.Location.GeoCoordinateWatcher.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 <xref:System.Device.Location.GeoCoordinateWatcher.PositionChanged> events are raised, and <xref:System.Device.Location.GeoCoordinateWatcher.Position*> returns P1. The point P5 is outside of the <xref:System.Device.Location.GeoCoordinateWatcher.MovementThreshold*> distance, so at that point, <xref:System.Device.Location.GeoCoordinateWatcher.Position*> is updated and a <xref:System.Device.Location.GeoCoordinateWatcher.PositionChanged> event is raised.

## Remarks
 This event is only raised when the distance moved since the last event exceeds the threshold that is specified by <xref:System.Device.Location.GeoCoordinateWatcher.MovementThreshold*>.

 The <xref:System.Device.Location.GeoPositionChangedEventArgs`1> object passed to the event handler includes the <xref:System.Device.Location.GeoPosition`1> object that contains the updated location data.

 The following example shows how to handle the first <xref:System.Device.Location.GeoCoordinateWatcher.PositionChanged> event.

## Remarks
 Calling this method will initiate the acquisition of data from the current location provider. The current location provider is selected based on factors such as the age and accuracy of the data from all providers, the accuracy requested by the application or applications, and the power consumption and performance impact associated with the location provider. The current location provider might change over time, for instance, when a GPS device loses its satellite signal indoors and a Wi-Fi triangulation provider becomes the most accurate provider on the computer.

 If the current prioritized location provider does not have data when the <xref:System.Device.Location.GeoCoordinateWatcher.Start*> method is called, it will start to acquire data. If the permissions have been granted to the client when the data becomes available, data can be accessed synchronously, and will be delivered asynchronously if events are being handled.

 If the Windows 7 Sensor and Location platform is disabled when <xref:System.Device.Location.GeoCoordinateWatcher.Start*> is called, <xref:System.Device.Location.GeoCoordinateWatcher.Start*> will immediately return, <xref:System.Device.Location.GeoCoordinateWatcher.PositionChanged> events will not be raised, and the location returned by the <xref:System.Device.Location.GeoPosition`1.Location> property of <xref:System.Device.Location.GeoCoordinateWatcher.Position*> will contain <xref:System.Device.Location.GeoCoordinate.Unknown>.

 If the current prioritized location provider does have data, it will be available synchronously immediately, and will be delivered asynchronously if events are being handled.

 If the calling application does not have permissions to access data from a location provider, the user will be prompted with a dialog box to either grant or deny permission. The dialog box will be modeless.



## Examples
 The following program handles the first location update that occurs after <xref:System.Device.Location.GeoCoordinateWatcher.Start*> is called.

## Remarks
 This method blocks execution of the calling thread during the time period specified by `timeout`. Use caution when calling <xref:System.Device.Location.GeoCoordinateWatcher.TryStart*> from the user interface thread of your application.



## Examples
 The following example demonstrates how to call <xref:System.Device.Location.GeoCoordinateWatcher.TryStart*>.
