J'ai un service Web simple pour permettre aux applications d'interroger ma CMDB. La fonction avec laquelle je rencontre des problèmes fonctionne avec un petit resultset mais échoue avec une plus grande, indiquant que c'est quelque chose dans la configuration du service WCF qui l'empêche de réussir.Impossible de comprendre le message d'erreur WCF, aide nécessaire
J'ai une application de test WinForms simple avec une référence de service au service Web et une seule fonction qui appelle la fonction en question. Le plus petit jeu de résultats renvoie ~ 120 Ko de XML, le plus grand jeu de résultats est ~ 2 Mo. J'ai essayé d'augmenter la taille de maxReceivedMessageSize et de maxStringContentLength sans succès.
Y at-il une config que j'ai raté? Je m'attendais à un message d'erreur plus détaillé si c'était le problème.
Merci à l'avance,
Nick
