+By default the plugin will track for geo updates while the application is in background and foreground. To stop tracking in foreground, the `MainPage.xaml.cs` file needs the following 2 methods:
+```c#
+namespace your.own.namespace
+{
+    public partial class MainPage : PhoneApplicationPage
+    {
+        /// </summary>
+        /// The page (the app) will enter the background and the background mode
