Problème: ObservableCollection et Wcf

Bonsoirs, je doit concevoir un service en WCF (Architecture SOA) le problème est que ma class OList qui hérite de ObservableCollection ne me rafraîchi pas sur le client lorsque les données son modifier il faut redémarrer le programme pour obtenir un rafraîchissement de la fenêtre...
Donc si quelqu'un a une idée..
Voilà une Partie du code
