Kommentarer

Om du vill hämta Configuration objektet för en resurs måste koden ha läsbehörighet för alla konfigurationsfiler som den ärver inställningarna från. Om du vill uppdatera en konfigurationsfil måste koden dessutom ha skrivbehörighet för både konfigurationsfilen och katalogen där den finns.
