i have following class give me current location in wp7:

public class position {     private geocoordinatewatcher watcher = null;     public geocoordinate currentlocation { get; set; }      public position()     {         obtaincurrentlocation();     }      private void obtaincurrentlocation()     {         watcher = new geocoordinatewatcher(geopositionaccuracy.default);         watcher.positionchanged += new eventhandler<geopositionchangedeventargs<geocoordinate>>(watcher_positionchanged);         watcher.start();     }      void watcher_positionchanged(object sender, geopositionchangedeventargs<geocoordinate> e)     {         //stop & clean up, don't need anymore         watcher.stop();         watcher.dispose();         watcher = null;          currentlocation = e.position.location;     }  } 

i want use location. instantiate it. how can make sure that, when call currentlocation property, location whould have been acquired?

you can make position class implement inotifypropertychanged , raise propertychanged when value of currentlocation property has changed.

code depends on currentlocation listen position.propertychanged , act appropriately when event raised.
