Commenti

Una finestra di progettazione può utilizzare IDesignerSerializationManager per accedere ai servizi utili per gestire i processi di serializzazione in fase di progettazione. Ad esempio, una classe che implementa la gestione serializzazione della finestra di progettazione può usare questa interfaccia per creare oggetti, cercare tipi, identificare gli oggetti e personalizzare la serializzazione di tipi specifici.
