Kommentarer

ASP.NET använder leverantörer för att utföra specifika tjänster som krävs av en funktion. Medlemskapsfunktionen använder till exempel en provider för att samordna beständigheten av medlemskapsdata i en databas.

I en konfigurationsfil läggs enskilda leverantörer till i ett providers element i ett visst funktionsavsnitt.

Klassen ProviderSettings representerar en viss grupp med inställningar som läggs till i elementet providers i ett konfigurationsavsnitt. De konfigurationsattribut som anges i add direktivet innehåller vanligtvis ett namn, en typ och andra egenskaper.
