WCF自托管服务配置

Question

我有一个非常简单的WCF服务，它托管在一个Windows应用程序中。我想通过 GET 方法访问该服务，但只是获取一个空页面。我猜配置有问题，但我无法弄清楚是什么。这是代码：

WCFService.cs

namespace WCFServiceApp
{
    [ServiceContract]
    public class WCFService
    {
        [OperationContract]
        [WebGet]
        public int GetNumbers()
        {
            return 12345;
        }
    }
}

Form1.cs的

private static Uri baseAddress = new Uri("http://localhost:8090");
private ServiceHost host = new ServiceHost(typeof(WCFService), baseAddress);

protected override void OnLoad(EventArgs e)
{
    ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
    smb.HttpGetEnabled = true;
    smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
    host.Description.Behaviors.Add(smb);
    host.Open();
    base.OnLoad(e);
}

的App.config

<?xml version="1.0"?>
<configuration>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup>
  <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="WCFServiceBehavior">
                    <serviceMetadata httpGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
            <endpointBehaviors>
              <behavior name="WebBehavior">
                <webHttp />
              </behavior>
            </endpointBehaviors>
        </behaviors>
        <services>
            <service name="WCFService" behaviorConfiguration="WCFServiceBehavior">
              <endpoint address="ws" binding="wsHttpBinding" contract="WCFService">
              </endpoint>
              <endpoint address="" behaviorConfiguration="WebBehavior" binding="webHttpBinding" contract="WCFService">
              </endpoint>
              <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
            </service>
        </services>
    </system.serviceModel>
</configuration>

当我使用浏览器点击 localhost：8090 时，我会看到WCF欢迎页面。当我点击 localhost：8090 / GetNumbers 时，只是获取一个空页而不是数字。
