Puoi dirci un po 'sulla vostra configurazione?

• che legame usi?
• è questo l'unico metodo di servizio? Se no: gli altri funzionano?
• mostraci le configurazioni su client e server! (Tutto dentro <system.serviceModel> è di interesse)

Sembrerebbe come se i tempi di client di attesa per il server - questo può essere perché il server richiede troppo tempo per rispondere (se si fa un sacco di caricamento dei dati); in tal caso, è necessario aumentare i timeout sul server e sul client

Oppure si potrebbe inviare un pacchetto di dati troppo grande sul cavo - in tal caso, potrebbe anche essere necessario aumentare le impostazioni per maxReceivedMessageSize e altri .

@Pinu: stai cercando di caricare 5 MB? Hai transferMode = StreamRequest, il che significa che la tua richiesta dal client al server verrà trasmessa in streaming.

Se si trasferiscono 5 MB, è una buona idea eseguire lo streaming - in che modo si trasferiscono quei byte?
