Uygulamaların CMDB'mi sorgulamasına izin vermek için basit bir web hizmetim var. Küçük bir sonuç kümesiyle çalışmamla ilgili sorun yaşıyorum ancak daha büyük bir hatayla başarısız oluyor, bu da WCF hizmet yapılandırmasında bir hata olduğunu ve bunun başarılı olmasını engelliyor.WCF hata mesajını anlayamıyorum, gerekli yardım
Web Service hizmet referansı ve söz konusu işlevi çağıran tek bir işlev ile basit bir WinForms test uygulamasına sahibim.
Daha küçük sonuç kümesi ~ 120 KB xml döndürür, başarısız olan daha büyük sonuç yaklaşık ~ 2 MB'dir. Ben başarılı olmadan maxReceivedMessageSize ve maxStringContentLength boyutunu artırmayı denedim.
Kaçırdığım bazı yapılandırma var mı? Sorun buysa daha detaylı bir hata mesajı bekliyordum. peşin
