Exemplos

Esta seção fornece dois exemplos de código. O primeiro demonstra como especificar valores declarativamente para várias propriedades da BuildProviderCollection classe. O segundo demonstra como usar membros da BuildProviderCollection classe.

O exemplo de arquivo de configuração a seguir mostra como especificar valores declarativamente para várias propriedades da BuildProviderCollection classe.

Comentários

O BuildProviderCollection é usado para compilar arquivos de recursos personalizados. Você pode ter qualquer número de provedores de build. O BuildProviderCollection não se refere a nenhum elemento real no arquivo de configuração subjacente. É um constructo que permite acesso fácil às informações de compilação que ele contém.
