Comentários

Um objeto deve implementar a ISponsor interface se precisar solicitar uma renovação de concessão para um objeto específico. Um objeto que implementa a ISponsor interface pode se tornar um patrocinador registrando-se no gerenciador de concessão. A ISponsor interface é usada pelo serviço de tempo de vida para chamar de volta para o patrocinador.
