Comentários

A ActivationArguments classe é usada pela AppDomainSetup classe.

O modelo de ativação baseado em manifesto usa um manifesto do aplicativo em vez de um assembly para ativação. Um manifesto descreve totalmente o aplicativo, suas dependências, requisitos de segurança e assim por diante. O modelo de manifesto tem várias vantagens em relação ao modelo de ativação baseado em assembly, especialmente para aplicativos Web. Por exemplo, o manifesto contém os requisitos de segurança do aplicativo, o que permite que o usuário decida se deseja permitir que o aplicativo seja executado antes de baixar o código. O manifesto também contém informações sobre as dependências do aplicativo.
