Exemplos

O exemplo a seguir mostra uma implementação muito simples de AppDomainManager.

// To replace the default AppDomainManager, identify  the
// replacement assembly and replacement type in the
// APPDOMAIN_MANAGER_ASM and APPDOMAIN_MANAGER_TYPE
// environment variables. For example:
// set APPDOMAIN_MANAGER_TYPE=library.TestAppDomainManager
// set APPDOMAIN_MANAGER_ASM=library, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f1368f7b12a08d72

Comentários

Implementar a AppDomainManager classe permite que um aplicativo de hospedagem participe da criação de novos domínios de aplicativo. Para substituir o padrão AppDomainManager, identifique o assembly e o tipo da substituição AppDomainManager nas variáveis de ambiente APPDOMAIN_MANAGER_ASM e APPDOMAIN_MANAGER_TYPE ou use os <elementos appDomainManagerAssembly> e <appDomainManagerType> no arquivo de configuração. O assembly deve ser totalmente confiável e estar contido no cache de assembly global ou no diretório do aplicativo inicial. Os nomes de tipo e assembly devem ser totalmente qualificados nas variáveis de ambiente. Por exemplo:

set APPDOMAIN_MANAGER_TYPE=MyNamespace.TestAppDomainManager

set APPDOMAIN_MANAGER_ASM=customappDomainmanager, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f1368f7b12a08d72

O AppDomainManager é o equivalente gerenciado do host não gerenciado. Um AppDomainManager objeto participa da criação de novos domínios de aplicativo em um processo e pode personalizar o novo AppDomain antes que outro código gerenciado seja executado. O AppDomainManager também pode fornecer gerenciadores de host que participam de outros aspectos da execução do Common Language Runtime. Por exemplo, um AppDomainManager pode identificar um HostSecurityManager objeto que participa das decisões de segurança do domínio do aplicativo.
