Esempio

Nell'esempio seguente viene illustrato l'effetto dell'uso del SetThreadPrincipal metodo per modificare l'entità disponibile per il collegamento ai thread in esecuzione nel dominio applicazione. Mostra anche l'effetto sui thread dell'uso del SetPrincipalPolicy metodo per modificare i criteri principali del dominio applicazione.
