自托管WCF服务的路由

我有一个自托管的WCF服务，可以侦听端口80（第三方设备不支持在其他端口上发送）。我还有两个网站和三个Web API基础服务，这些服务也在端口80上运行良好。所有这些服务/站点都使用不同的FQDN（test-svc1.example.com，test-svc2.example.com，test-site1.example.com等）运行。请务必注意，所有子域都指向服务器上的相同IP地址。所有这一切都很有效，直到我尝试安装托管我的WCF服务的服务。当我尝试导航到我的两个站点之一时安装该服务后，我会得到一个页面，其中包含以下信息：

.....

您已创建了一项服务。

要测试此服务，您需要创建一个客户端并使用它来调用该服务。您可以使用命令行中的svcutil.exe工具执行此操作，语法如下：

.....

如果我停止基于WCF的服务，那么我的网站工作正常。

以下是用于托管WCF服务的代码。     公共类MyService     {         private const string MyServiceName =“MyService”;         私人ServiceHost _selfHost; 

    public void Start()
    {
        this._selfHost = new ServiceHost(typeof(MyWebService), new Uri(wcf.exampe.com));

        try
        {
            BasicHttpBinding binding = new BasicHttpBinding();
            int tempValue = 0;
            this._selfHost.AddServiceEndpoint(typeof(IMyServiceContract), binding, MyServiceName);

            ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
            smb.HttpGetEnabled = true;
            this._selfHost.Description.Behaviors.Add(smb);

            this._selfHost.Open();

        }
        catch ( CommunicationException ce )
        {
            this._selfHost.Abort();
        }
    }

    public void Stop()
    {
        // Close the ServiceHostBase to shutdown the service.
        this._selfHost.Close();

    }
}

此代码由Windows服务包装程序调用。我需要的是这个服务能够在端口80上运行，但只监听与wcf.example.com相关的数据包。

我已在事件查看器中启用调试和跟踪，以查看是否可以帮助我隔离问题。以下是其中的一些项目。

如前所述，在Visual Studio下运行时，所有这些都可以在我的测试框中正常工作，但在我的生产盒作为服务运行时不起作用。
