Kann nicht verstehen, WCF Fehlermeldung, Hilfe benötigt

Habe ich eine einfache web-service, um Anwendungen zu meine Abfrage CMDB. Die Funktion habe ich bin Probleme mit, funktioniert mit einem kleinen resultset scheitert aber mit einem größeren, was darauf hinweist, dass es etwas in der WCF-service-config, die verhindern, dass es gelingt.

Habe ich eine einfache WinForms-test-app mit einer Service-Referenz auf den web service und eine einzelne Funktion, die ruft die Funktion in Frage stellen.

Den kleineren Ergebnismenge zurückgibt ~120KB von xml, die in Ermangelung größeren Ergebnismenge ist ~2MB. Ich habe versucht, die Erhöhung der Größe der maxReceivedMessageSize und maxStringContentLength ohne Erfolg.

Gibt es einige config habe ich verpasst? Ich würde erwarten, dass eine genauere Fehlermeldung, wenn das war das problem.

Vielen Dank im Voraus,

Nick
