我们目前正在尝试在我们的 WCF 服务中实现 NServiceBus 3.0。

我们使用自定义的 ServiceHostFactory 来初始化 WAS 中的服务。我们使用 net.tcp 来访问服务并使用以下代码进行设置：

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;
    }
}

当我们调用服务时，我们收到此错误：

    Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

以及web.config中的配置部分

<section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" />

有什么想法吗？

通常（至少在 2.6 中），您会将 Windsor Container 的实现传递给.CastleWindsorBuilder配置。这允许 NSB 在初始化时创建正确的对象图。所以，它看起来像：

        _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);

这有帮助吗？
