HTTP错误404.0 - 在IIS服务器上找不到wcf路由

Question

我在WCF项目中有以下提到的设置但是当我在IIS服务器中部署它时，当我尝试访问我的网站时出现404错误：http://mysite.com/MyService Global.asax中：

public class Global : System.Web.HttpApplication
{

    protected void Application_Start(object sender, EventArgs e)
    {
        RouteTable.Routes.Add(new ServiceRoute("MyService", new AppServiceHostFactory(), typeof(UserService)));
    }

MyService.cs：

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]

public class MyService : IMyService
{

的Web.config：

<system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules runAllManagedModulesForAllRequests="true">
        <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    </modules>
