   permissions );

PermissionSet permissions 
    = new PermissionSet(PermissionState.Unrestricted);
permissions.AddPermission(
    new SecurityPermission(SecurityPermissionFlag.Execution));

Cuidado

O CAS (Segurança de Acesso do Código) foi preterido em todas as versões do .NET Framework e do .NET. As versões recentes do .NET não aceitam anotações de CAS e produzem erros caso as APIs relacionadas ao CAS sejam usadas. Os desenvolvedores devem buscar meios alternativos de realizar tarefas de segurança.
