WcfFacility 序列不包含任何元素

Question

在尝试安装我的 wcf 服务时，我不断收到 Sequence contains no elements 错误。

这是我 global.asax 中的代码：

_container = new WindsorContainer();

_container.Register(Component.For<IWindsorContainer>().Instance(_container))
          .AddFacility<WcfFacility>()
          .Install(Configuration.FromAppConfig())
          .Install(FromAssembly.InDirectory(new AssemblyFilter(HttpRuntime.BinDirectory, "Web*.dll")));

这是我在 web.config 中的 system.servicemodel 部分：

<system.serviceModel>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
  <client>
    <endpoint address="http://commandservice.website.com/WebsiteCommandService.svc" binding="basicHttpBinding" contract="CommandService.IWebsiteCommandService" name="commandServiceClient"></endpoint>
  </client>
</system.serviceModel>

这是我的城堡配置（在 web.config 中）：

<castle>
    <components>
      <component
          id="commandService"
          type="CommandService.WebsiteCommandService, CommandService"
          wcfEndpointConfiguration="commandServiceClient" />
    </components>
</castle>

我是否遗漏了一些明显的东西？

更新

现在问题似乎出在其他地方 - 就像它正在尝试解析组件，就好像它是一个普通对象而不是 wcf 服务一样。牢记服务有效 - 尝试使用 wcf 解决它时，我在 ctor 上收到错误：

    public WebSiteCommandService(ICommandService service)
    {
        _service = service;
    }

它说没有 ICommandService 的组件

为什么客户端容器试图解决这个问题？

好像 wcffacility 的东西被完全跳过了？

Answer 1

我认为您的 web.config 中的 system.servicemodel 元素不太正确。如果您从 Web 应用程序托管服务，则其中不会有客户端元素 - 而不是客户端元素，我认为您应该有一个如下所示的服务元素：

<services>
  <service name="CommandService.WebsiteCommandService">
    <endpoint address="http://commandservice.website.com/WebsiteCommandService.svc"
              binding="basicHttpBinding"
              name="commandService"
              contract="CommandService.IWebsiteCommandService" />
  </service>
</services>   

Answer 2

我终于搞定了！！

组件配置中的类型需要是接口 - 服务。我省略了服务属性，它开始行动！

并且 system.servicemodel 与客户端配置一起使用。

不知道是不是bug？
