Базовый хостинг WCF через TCP

Question

Я пытаюсь разместить службу wcf в службе windows по tcp. Все идет нормально до этапа установки сервиса и запуска его. Однако, когда я добавил клиентское приложение и при попытке добавить ссылку на службу, я получаю эту ошибку.

System.ServiceModel.AddressAlreadyInUseException: 
There is already a listener on IP endpoint 0.0.0.0:8523. 
Make sure that you are not trying to use this endpoint multiple times 
in your application and that there are no other applications listening 
on this endpoint. --->

Это из-за межсетевого экрана или какой-либо другой проблемы? Это очень простой сервис, и конечная точка приведена ниже: net.tcp://localhost:8523/CalculatorService.

Вот конфигурационный файл:

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 

    <system.web> 
    <compilation debug="true" /> 
    </system.web> 
    <!-- When deploying the service library project, the content of the config file must be added to the host's 
    app.config file. System.Configuration does not support config files for libraries. --> 
    <system.serviceModel> 
    <services> 
     <service name="Service.CalculatorService"> 
     <endpoint address="" binding="netTcpBinding" bindingConfiguration="" 
      contract="Service.ICalculatorService"> 
      <identity> 
      <dns value="localhost" /> 
      </identity> 
     </endpoint> 
     <endpoint address="mex" binding="netTcpBinding" bindingConfiguration="" 
      contract="IMetadataExchange" /> 
     <host> 
      <baseAddresses> 
      <add baseAddress="net.tcp://localhost:8523/CalculatorService" /> 
      </baseAddresses> 
     </host> 
     </service> 
    </services> 
    <behaviors> 
     <serviceBehaviors> 
     <behavior name=""> 
      <serviceMetadata httpGetEnabled="false" /> 
      <serviceDebug includeExceptionDetailInFaults="false" /> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors> 
    </system.serviceModel> 

</configuration> 

и код услуги:

public partial class Service1 : ServiceBase 
    { 
     internal static ServiceHost myServiceHost = null; 

     public Service1() 
     { 
      InitializeComponent(); 
     } 
     protected override void OnStart(string[] args) 
     { 
      if (myServiceHost != null) 
      { 
       myServiceHost.Close(); 
      } 
      myServiceHost = new ServiceHost(typeof(CalculatorService)); 
      myServiceHost.Open(); 
     } 
     protected override void OnStop() 
     { 
      if (myServiceHost != null) 
      { 
       myServiceHost.Close(); 
       myServiceHost = null; 
      } 
     } 

Я справлялся конфигурационный файл из библиотеки WCF службы для проекта окна обслуживания, и они идентичны.

попробовать этот код:

protected override void OnStart(string[] args) 
{ 
    if (myServiceHost != null) 
    { 
     myServiceHost.Close(); 
    } 
    Uri baseAddress = new Uri("http://localhost:8523/CalculatorService"); 
    myServiceHost = new ServiceHost(typeof(CalculatorService), baseAddress); 
    myServiceHost.Open(); 
} 

и этот Web.config

<?xml version="1.0"?> 
<configuration> 

    <system.web> 
    <compilation debug="true" targetFramework="4.0" /> 
    </system.web> 
    <system.serviceModel> 
    <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> 
    </behaviors> 
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 
    </system.serviceModel> 
<system.webServer> 
    <modules runAllManagedModulesForAllRequests="true"/> 
    </system.webServer> 

</configuration>
