Typy chýb WCF nie je možné zaregistrovať pri otvorenej službe - c #, .net, wcf, rest

V súčasnej dobe máme aplikáciu, ktorá má aserverová aplikácia, ktorá vystavuje službu WCF REST, a potom máme stranu klienta, ktorá komunikuje so službami WCF REST na serveri. Momentálne sa mi na strane klienta zobrazuje chyba, ktorú nedokážem zistiť, a nemám šťastie v hľadaní odpovedí Google.

Hneď ako zavolám zChannelFactory na vytvorenie kanála je vyvolaná nasledujúca výnimka. Vie niekto, čo znamená táto chyba a kde nájdem niečo, čo by mi pomohlo problém vyriešiť? Ďalej je uvedená všeobecná metóda, ktorú používame na volanie služby zo strany klienta. Fiddler neukazuje žiadnu komunikáciu vychádzajúcu z klienta, takže problém je priamo na strane klienta. Server aj klient zdieľajú rovnaké komunikačné rozhranie.

odpovede:

Riešenie problému spočíva v generikeMetóda zverejnená. Z nejakého dôvodu preto, že vo vyhlásení try / konečne sa vykonáva iba delegát, ktorý sa nakoniec nikdy nevykonával. Oprava tejto metódy je presunúť koniec do vnútra pokusu pomocou delegátskeho kódu a kanál nakoniec zlikvidovať. Ďalej uvádzame opravenú všeobecnú metódu.
