Observações

Fornece WSHttpBindingBase algumas funcionalidades básicas para as ligações usadas para configurar serviços Web seguros, fiáveis e interoperáveis, como o implementado WSHttpBinding pelos contratos de serviços não-duplex e, mais particularmente, para o seguro e interoperável WSFederationHttpBinding que suporta o protocolo WS-Federation.

Por defeito, gera uma pilha em tempo de execução que utiliza WS-Security para segurança e autenticação de mensagens, HTTP para entrega de mensagens e codificação de mensagens de texto/XML. Pode ser configurado para também usar WS-ReliableMessaging fiabilidade.

O uso de WS-ReliableMessaging é configurável usando o parâmetro opcional reliableSessionEnabled .
