Procedura: creare un elemento SecurityBindingElement per una modalità di autenticazione specificata

Articolo
04/10/2024

Windows Communication Foundation (WCF) offre diverse modalità per l'autenticazione reciproca di client e servizi. È possibile creare elementi di associazione di sicurezza per tali modalità di autenticazione utilizzando metodi statici sulla classe SecurityBindingElement o tramite configurazione, come spiegato nell'esempio seguente.

Per altre informazioni sulle 18 modalità di autenticazione, vedere Modalità di autenticazione SecurityBindingElement.

Esempio

Nell'esempio di codice seguente sono illustrati i metodi per la creazione di associazioni per le varie modalità di autenticazione.

Nota

Dopo la creazione di un'istanza dell'oggetto SecurityBindingElement, diverse proprietà sono immutabili, ad esempio KeyType e MessageSecurityVersion. Non cambiano neppure chiamando set su di esse.

// These public methods create custom bindings based on the built-in
// authentication modes that use the static methods of
