現在、WCFサービスにNServiceBus3.0を実装しようとしています。

カスタムServiceHostFactoryを使用して、WASでサービスを初期化します。net.tcpを使用してサービスにアクセスし、次のコードを使用してサービスを設定します。

public class DoServiceServiceHostFactory : DefaultServiceHostFactory
{
    private static IWindsorContainer _container;

    public DoServiceServiceHostFactory()
        : base(CreateKernel())
    {
    }

    private static IKernel CreateKernel()
    {
        _container = new WindsorContainer();

        IocModules.Configure(_container, new WcfConfigurationModule());
        IocModules.Configure(_container, new WcfAdapterModule());
        IocModules.Configure(_container, new ManagerModule());
        IocModules.Configure(_container, new FactoryModule());

        IBus bus = Configure.WithWeb()
                .DefineEndpointName("OurProjectPublisher")
                .DefiningEventsAs(t => t.Namespace != null && t.Namespace.StartsWith("MY.Bus.Contracts.Events"))
                .CastleWindsorBuilder()
                .Log4Net()
                .XmlSerializer()
                .MsmqTransport()
                .UnicastBus()
                .CreateBus()
                .Start(() => Configure.Instance.ForInstallationOn<NServiceBus.Installation.Environments.Windows>().Install());
        //_container.Register(Component.For<IBus>().Instance(bus).LifeStyle.Singleton);

        WindsorServiceLocator serviceLocator = new WindsorServiceLocator(_container);
        ServiceLocator.SetLocatorProvider(() => serviceLocator);

        return _container.Kernel;
    }
}

サービスを呼び出すと、次のエラーが発生します。

    Object reference not set to an instance of an object.

これについて何かアイデアはありますか？

通常 (少なくとも 2.6 では)、Windsor コンテナーの実装を.CastleWindsorBuilder構成に渡します。これにより、NSB は初期化時に正しいオブジェクト グラフを作成できます。したがって、次のようになります。

        _container = new WindsorContainer();

        IocModules.Configure(_container, new WcfConfigurationModule());
        IocModules.Configure(_container, new WcfAdapterModule());
        IocModules.Configure(_container, new ManagerModule());
        IocModules.Configure(_container, new FactoryModule());

        IBus bus = Configure.WithWeb()
                .DefineEndpointName("OurProjectPublisher")
                .DefiningEventsAs(t => t.Namespace != null && t.Namespace.StartsWith("MY.Bus.Contracts.Events"))
                .CastleWindsorBuilder(_container)  // added here
                .Log4Net()
                .XmlSerializer()
                .MsmqTransport()
                .UnicastBus()
                .CreateBus()
                .Start(() => Configure.Instance.ForInstallationOn<NServiceBus.Installation.Environments.Windows>().Install());
        //_container.Register(Component.For<IBus>().Instance(bus).LifeStyle.Singleton);

それは役に立ちますか？
