Comentarios

Opcionalmente outOfBand , un solucionador de tokens puede devolverlo el método , que usa el procesador de seguridad wcF para resolver los tokens que no están en el mensaje SOAP al procesar la seguridad. Que SecurityTokenAuthenticator devuelve este método valida los tokens y extrae notificaciones. Se crea uno SecurityTokenAuthenticator para cada clase derivada de ServiceModelSecurityTokenRequirement.
