Have to register every class before the container can resolve?

[沈斌]

let's say this scenario:

public class B {};

public class C

{

     public C(B b){}

}

To resolve C from Autofac container, I have to register both B and C to container.

But, today I used Unity, it seems I just need to register B to container, then C can be resolved.

So Autofac can't do as Unity do?

sorry for poor English.

This is possible with Autofac - see:

However, while it seems convenient, I think it's a bad feature to rely on. For example, Prism relies on some objects being resolvable (without registration), but since it doesn't register them, it never sets the lifetime. You can waste hours trying to work out why things aren't behaving as expected only to find out that an obscure piece of code assumed it had a transient but got a singleton. 

If you have lots of B's and C's, you could use Autofac's assembly registration syntax to find and register them all instead:
