Can I create an implicit Lifetime scope within a factory?

问题

Does Autofac support implicit lifetime scopes for the use of a factory? For example, I would like to be able to do the following

public class Session : IDisposable
{
    public Session(A a, B b, C c)
    {
        ...
    }
} 

...

using (var session = _sessionFactory())
{
    ...
}

and then upon each call to the _sessionFactory have Autofac automatically create a nested lifetime scope?

回答1:

Yes. Let the factory return Owned<Session>. Owned instances indicates that the calling code is responsible for disposing the service. Actually, if you resolve a Func<Owned<Session>> from the container, Autofac will give you an automatic factory that produces such instances.
