Interaction entre WebService et silverlight
bonjour,
j'utilise un web service pour me creer des fichier sur le disk (ou sur le serveur) .
sauf que quand je passe par le silverlight il le repond pas et le webs ervice ne cree pas les fichier .
mais quand je le test sans le silverlight ca fonctionne .
voici mon code du silverlight :
