For some context, I'm working with Windsor and asp.net webapi. There's a
webapicontrib project that provides what is effectively a controllerfactory
(in this case an IDependencyResolver) that is implements its scopes by
using a child container. Specifically, each request is handled by a child
container that is then disposed at the end of the request. All my
registrations are done at the parent level.
Now, onto the problem.
What I was expecting is that once the child container was disposed, all the
transient components that were resolved via that container would be
disposed as well (if my controller had some dependencies that were
IDisposable I would expect them to get disposed). In fact, nothing gets
disposed. If I debug, I see that the components are actually listed under
the _parent's_ "Objects tracked by release policy" and nothing is tracked
at the child level at all. Since the parent scope lives for the life of
the app, those bits are never cleaned up.
Am I misunderstanding how child containers are supposed to work?
Here's a very brief sample. "Disposed" is never printed.
interface ITest
{
}
class Tester : ITest, IDisposable
{
public Tester()
{
Console.WriteLine("Created");
}
public void Dispose()
{
Console.WriteLine("Disposed");
}
}
class Program
{
static void Main(string[] args)
{
var parent = new WindsorContainer();
parent.Register(Component.For<ITest>().ImplementedBy<Tester>().LifestyleTransient());
var child = new WindsorContainer();
parent.AddChildContainer(child);
var i = child.Resolve<ITest>();
child.Dispose();
Console.WriteLine("Done");
Console.ReadLine();
}
}
