Castle Windsor: is there a way of validating registration without a resolve call?

Question

My current understanding of Castle Windsor registration is that one can only validate registration by calling Resolve on a root component. But since windsor\'s component model k

OK, It is possible. Thanks to Krzysztof Koźmic for showing me how. Not immediately obvious, but you can use Windsor's diagnostic subsystem to raise potential problems with registration. I've put together a little static method that throws if there are any misconfigured components:

private static void CheckForPotentiallyMisconfiguredComponents(IWindsorContainer container)
{
    var host = (IDiagnosticsHost)container.Kernel.GetSubSystem(SubSystemConstants.DiagnosticsKey);
    var diagnostics = host.GetDiagnostic<IPotentiallyMisconfiguredComponentsDiagnostic>();

    var handlers = diagnostics.Inspect();

    if (handlers.Any())
    {
        var message = new StringBuilder();
        var inspector = new DependencyInspector(message);

        foreach (IExposeDependencyInfo handler in handlers)
        {
            handler.ObtainDependencyDetails(inspector);
        }

        throw new MisconfiguredComponentException(message.ToString());
    }
}

You can use it like this:

var container = new WindsorContainer().Register(
    Component.For<IRoot>().ImplementedBy<Root>()
    );

CheckForPotentiallyMisconfiguredComponents(container);

In this case I get a MisconfiguredComponentException with this message:

'WindsorSpikes.Root' is waiting for the following dependencies:
- Service 'WindsorSpikes.IChild' which was not registered.

WindsorSpikes.MisconfiguredComponentException:
'WindsorSpikes.Root' is waiting for the following dependencies:
- Service 'WindsorSpikes.IChild' which was not registered.
