Gestion des erreurs WCF dans Silverlight 4
Bonjour à tous,
Dans mon application silverlight, je tombe sur cette erreur apparemment classique lorsqu'un service wcf est utilisé :
Citation:
CommunicationException "NotFound" en appel distant.
J'ai cherché à droite à gauche sur le net et j'ai trouvé le pourquoi de cette erreur : http://msdn.microsoft.com/fr-fr/libr...96(VS.95).aspx
Mais voila, aprés avoir fait le nécessaire, j'ai toujours cette fameuse erreur. Voici le code ajouté dans mon service WCF :

A noter que dans une application winforms, je récupère bien mon Exception par le biais de mon FaultException.
Quelqu'un pourrait il me dire ce qui pourrait clocher ?
Merci à vous tous d'avance.
