Exemples
L'exemple de code suivant crée des gestionnaires d'événements qui permettent à l'exemple d'application de signaler à la console la progression et l'état. Pour consulter ce code dans le contexte d'une application complète, consultez l'application "Sync101 using Simple Sync Provider" qui est disponible dans le Kit de développement logiciel (SDK) Sync Framework et de Code Gallery.
