Comentários

Para obter o Configuration objeto de um recurso, seu código deve ter privilégios de leitura em todos os arquivos de configuração dos quais herda as configurações. Para atualizar um arquivo de configuração, o código também deve ter privilégios de gravação para o arquivo de configuração e o diretório no qual ele existe.
