Comentarios

Cuando se invalida el método GetTokenCore y el token de seguridad pasado en el parámetro de token no se puede obtener, producir la excepción SecurityTokenException.

La clase GetToken que llama al método ClientCredentials cuando un cliente envía un mensaje SOAP y se requiere un token de seguridad.

El método GetToken llama al método GetTokenCore.
