Nasıl yapılır: ChannelFactory Kullanma
Genel ChannelFactory<TChannel> sınıfı, birden fazla kanal oluşturmak için kullanılabilecek bir kanal fabrikası oluşturulmasını gerektiren gelişmiş senaryolarda kullanılır.
ChannelFactory sınıfını oluşturmak ve kullanmak için
Bir Windows Communication Foundation (WCF) hizmeti derleyin ve çalıştırın. Daha fazla bilgi için bkz. Hizmetleri Tasarlama ve Uygulama, Hizmetleri Yapılandırma ve Barındırma Hizmetleri.
İstemcinin sözleşmesini (arabirimi) oluşturmak için ServiceModel Meta Veri Yardımcı Programı Aracı'nı (Svcutil.exe) kullanın.
İstemci kodunda, sınıfını ChannelFactory<TChannel> kullanarak birden çok uç nokta dinleyicisi oluşturun.
