MetadataImportWithIssuedTokenOverSslExample
En este ejemplo se ilustra la importación de metadatos desde un punto de conexión que admite el uso de un token emitido que se obtiene del servicio de token de seguridad (STS) emisor mediante WsRequestSecurityToken y se presenta al servicio mediante WS_XML_TOKEN_MESSAGE_SECURITY_BINDING con WS_SSL_TRANSPORT_SECURITY_BINDING. Consulte Federación para obtener más información.
