Again and again on Castle and lifecycle.

You can find at this subversion repository ( http://nablasoft.googlecode.com/svn/trunk/Castle/TestIOC ) a simple project that contains a custom lifecycle that bound the lifecycle of objects to a context. This lifecycle was created to address the problem of disposing inner object, you can find the deails here. This new version support both singleton and transient objects, this a sample test.

        [Test]
        public void BaseTestSingletonContextDisposable3() {
            DisposableComponent tran1, tran2;
            using (WindsorContainer ioc = new WindsorContainer(new XmlInterpreter("ConfigurationCustom.xml"))) {
                using (ContextLifecycle.BeginThreadContext()) {
                    tran1 = ioc.Resolve<DisposableComponent>("SingletonDisposableCon");
                    tran2 = ioc.Resolve<DisposableComponent>("SingletonDisposableCon");
                    Assert.That(tran1, Is.EqualTo(tran2));
                    Assert.That(tran1.ITest, Is.EqualTo(tran2.ITest));
                }
                Assert.IsTrue(tran1.ITest.IsDisposed);
                Assert.IsTrue(tran2.ITest.IsDisposed);
                Assert.IsTrue(tran1.IsDisposed);
                Assert.IsTrue(tran2.IsDisposed);
            }
        }

This test shows that an object with singletonContext custom lifecycle is singleton inside a context, and when the context ends all it gets disposed and all the inner references are disposed too. This lifecycle has the main purpose of estabilishing a context that once ended dispose every object created inside the context itself.

The code is still experimental, but it can be a viable solution.
