c# - クライアントにエンドポイントが見つかりません

Question

サービスがあります（EmailSender）。これは設定ファイルです：

<?xml version="1.0"?>
<configuration>
  <connectionStrings>
    <add name="Conn" connectionString="Data Source=localhost;Initial Catalog=DT.DBTest;Integrated Security=True"
      providerName="System.Data.SqlClient" />
  </connectionStrings>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding name="webHttpBindingWithJsonP" crossDomainScriptAccessEnabled="true" />
      </webHttpBinding>      
    </bindings>
    <services>
      <service name="DT.myapp.Services.PremieraInteraction">
        <endpoint address="" binding="webHttpBinding"
                  bindingConfiguration="webHttpBindingWithJsonP"
                  contract="DT.myapp.Services.IPremieraInteraction"
                  behaviorConfiguration="webHttpBehavior"/>
      </service>
      <service name="DT.myapp.Services.EmailSender">
        <endpoint address="" binding="webHttpBinding"
                  contract="DT.myapp.Services.IEmailSender"
                  behaviorConfiguration="webHttpBehavior"/>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>       
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="webHttpBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

他の（asp.net mvc）アプリケーションでは、このサービスを呼び出したいと思います。これはプロキシクラスです：

    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
    [System.ServiceModel.ServiceContractAttribute(ConfigurationName = "IEmailSender")]
    public interface IEmailSender
    {

        [System.ServiceModel.OperationContractAttribute(Action = "http://tempuri.org/IEmailSender/SendRegistrationEmail", ReplyAction = "http://tempuri.org/IEmailSender/SendRegistrationEmailResponse")]
        void SendRegistrationEmail();

        [System.ServiceModel.OperationContractAttribute(Action = "http://tempuri.org/IEmailSender/SendETicket", ReplyAction = "http://tempuri.org/IEmailSender/SendETicketResponse")]
        void SendETicket();

        [System.ServiceModel.OperationContractAttribute(Action = "http://tempuri.org/IEmailSender/SendTestEmail", ReplyAction = "http://tempuri.org/IEmailSender/SendTestEmailResponse")]
        void SendTestEmail();
    }

    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
    public interface IEmailSenderChannel : IEmailSender, System.ServiceModel.IClientChannel
    {
    }

    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
    public partial class EmailSenderClient : System.ServiceModel.ClientBase<IEmailSender>, IEmailSender
    {

        public EmailSenderClient()
        {
        }

        public EmailSenderClient(string endpointConfigurationName) :
            base(endpointConfigurationName)
        {
        }

        public EmailSenderClient(string endpointConfigurationName, string remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
        {
        }

        public EmailSenderClient(string endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
        {
        }

        public EmailSenderClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) :
            base(binding, remoteAddress)
        {
        }

        public void SendRegistrationEmail()
        {
            base.Channel.SendRegistrationEmail();
        }

        public void SendETicket()
        {
            base.Channel.SendETicket();
        }

        public void SendTestEmail()
        {
            base.Channel.SendTestEmail();
        }
    }

そして、私が電話をかける方法：

Binding binding = new BasicHttpBinding(BasicHttpSecurityMode.None);
EndpointAddress endpointAddress = new EndpointAddress(new Uri("http://localhost:12736/EmailSender.svc"));
EmailSenderClient client = new EmailSenderClient(binding, endpointAddress); 
client.SendTestEmail();

しかし、エラーが発生します：

There was no endpoint listening at http://localhost:12736/EmailSender.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

InnerException言う：

The remote server returned an error: (404) Not Found.

エラーはどこにありますか？
ありがとう。
