as for disposal: only 2 of the supported containers support automatic disposal of disposable transient dependencies.  All the others don’t, regardless of whether you use something like Agatha or its container abstraction.  The disposal burden rests entirely upon you in those cases.  Agatha’s container abstraction at least uses the ability with the containers that implement it.

“The container should be responsible for what is is good at: registration, resolving dependencies, cleanup and disposal.”

the whole point of this abstraction is to use the actual container for all of that (with the possible exception of disposal, since most containers don’t handle that properly) but to not force you, the consumer, to worry about correct registration of all required components.

i’m pretty sure the time-savings of not having to deal with support-requests from people who misconfigured one of the components are worth it, not to mention the fact that configuration of Agatha is now a very minimal and easy step for users.

Also, Agatha’s IContainer implementation is meant to be used _by Agatha_, not by the user.  A user can use it, but i’d expect, and recommend, users to use their containers directly without any abstractions.  All they need to do is pass their container instance to Agatha’s configuration object and that’s all there is to it.

For example, it has too many methods to implement.  Also, your approach does not support lifetime or unit of work easily.  Your approach only supports disposal with two containers.  All the other container implementations leak memory.

I also feel like scanning assemblies should be the responsibility of the container and not Agatha.  Why not make explicit interface for outsourcing these implementations to the container.  NServiceBus does the same thing and it is simply unintuitive for the developer.

The container should be responsible for what is is good at: registration, resolving dependencies, cleanup and disposal.

glad to know other people are using this approach as well… while i was working on this i couldn’t help think “i can’t be the only one who wants to do it like _this_”

Anyways, interesting posts. Good luck with Agatha!
