Observações

Os tipos ativados pelo servidor podem ser de chamada única ou singleton. Se uma classe for registada como um único tipo de chamada, uma nova instância é criada cada vez que chega uma chamada do cliente. Todas as chamadas a um objeto singleton são tratadas por uma instância desse objeto, a menos que esse objeto tenha sido recolhido.

Qualquer cliente que conheça o URI de um objeto ativado pelo servidor registado pode obter um proxy para esse objeto registando o canal com ChannelServices que prefere e ativando o objeto ao chamar new ou Activator.GetObject. Para ativar um objeto ativado pelo servidor com new, deve primeiro registar o tipo de objeto ativado pelo servidor no cliente usando o RegisterWellKnownClientType método. Ao chamar RegisterWellKnownClientType, está a dar à infraestrutura remota a localização do objeto remoto, o que permite que a new palavra-chave o crie. Se, por outro lado, usar o Activator.GetObject método para ativar um objeto ativado pelo servidor, deve fornecer-lhe a URL do objeto como argumento, pelo que não é necessário registo prévio no cliente.

Para uma descrição detalhada de objetos ativados pelo servidor e ativação remota de objetos, veja Ativação de Objetos Remotos.
