Observações

É WSHttpBinding semelhante ao BasicHttpBinding mas oferece mais funcionalidades de serviço Web. Utiliza o transporte HTTP e fornece segurança de mensagens, tal como BasicHttpBinding, mas também fornece transações, mensagens fiáveis e WS-Addressing, que estão ativados por defeito ou disponíveis através de uma única configuração de controlo.
