Tengo un servicio web simple para permitir que las aplicaciones consulten mi CMDB. La función con la que estoy teniendo problemas funciona con un pequeño conjunto de resultados pero falla con uno más grande, lo que indica que es algo en la configuración del servicio WCF que impide que tenga éxito.No se puede entender el mensaje de error de WCF, se necesita ayuda
Tengo una aplicación de prueba WinForms simple con una referencia de servicio para el servicio web y una sola función que llama a la función en cuestión.
El conjunto de resultados más pequeño arroja ~ 120KB de xml, el conjunto de resultados más grande que falla es ~ 2MB. Intenté aumentar el tamaño de maxReceivedMessageSize y maxStringContentLength sin éxito.
¿Hay alguna configuración que me he perdido? Esperaría un mensaje de error más detallado si ese era el problema.
Gracias de antemano,
Nick
