Kommentarer

BuildProviderCollection Används för att kompilera anpassade resursfiler. Du kan ha valfritt antal byggleverantörer. BuildProviderCollection Refererar inte till något faktiskt element i den underliggande konfigurationsfilen. Det är en konstruktion som gör det enkelt att komma åt kompileringsinformationen som den innehåller.
