Kommentarer

Klassen ActivationArguments används av AppDomainSetup klassen.

Den manifestbaserade aktiveringsmodellen använder ett programmanifest i stället för en sammansättning för aktivering. Ett manifest beskriver programmet fullständigt, dess beroenden, säkerhetskrav och så vidare. Manifestmodellen har flera fördelar jämfört med den sammansättningsbaserade aktiveringsmodellen, särskilt för webbprogram. Manifestet innehåller till exempel programmets säkerhetskrav, vilket gör att användaren kan bestämma om programmet ska kunna köras innan koden laddas ned. Manifestet innehåller också information om programberoenden.
