Question

我在服务启动时有一些一次性的初始化任务，为了做到这一点，我已经定义了一个自定义的ServiceHostFactory和ServiceHost来覆盖InitializeRuntime。

Service1.svc标记：

<%@ ServiceHost Language="C#" Debug="true" Factory="service.Our_Service_Host_Factory" Service="service.Service1" CodeBehind="Service1.svc.cs" %>

服务主机定义：

public class Our_Service_Host_Factory : ServiceHostFactory
{
    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
    {
        return new Our_Service_Host(serviceType, baseAddresses);
    }
}

class Our_Service_Host : ServiceHost
{
    public Our_Service_Host(Type serviceType, Uri[] baseAddresses)
        : base(serviceType, baseAddresses) { }

    protected override void InitializeRuntime()
    {
         // one time setup code
    }
}

来自web.config的

小部件：

<system.serviceModel>
  <behaviors>
    <serviceBehaviors>
      <behavior>
        <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
        <serviceDebug includeExceptionDetailInFaults="false"/>
      </behavior>
    </serviceBehaviors>
  </behaviors>
  <protocolMapping>
    <add binding="basicHttpsBinding" scheme="https" />
  </protocolMapping>    
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>

如果我删除ServiceHost标记上的Factory属性，WCF测试客户端可以成功连接到我的服务。如果我将其重新插入，则无法找到具有以下错误的元数据端点：

Error: Cannot obtain Metadata from http://localhost:50154/Service1.svc If this is a Windows (R)

metadata publishing at the specified address.  For help enabling metadata publishing, please

看起来自定义ServiceHost / ServiceHostFactory可能会破坏简化配置。是这样的，还是有什么我忽视的东西会让它继续发挥作用？

Answer 1

如果覆盖InitializeRuntime（），请确保调用base.InitializeRuntime（），否则您可能会看到此行为。在调用我的附加启动逻辑之前调用base.InitializeRuntime（）之后，我的服务现在正确地路由到。

使用自定义ServiceHost是否禁用简化配置？
