Ошибка при создании ФОС .svc службы

Question

Я создал следующие SVC службы данной конфигурации ценам ниже

public class NewsRest : INewsRest 
{ 
    public string getHomePageNews1() 
    { 
     DataTable dt = new DataTable(); 
     try 
     { 

      dt = new ManageNews().getHomePageNews1(); 
      string json = new Utills().dataTableToJsonString(dt); 
      json = json.Replace("task-photo-846b6edc-3b2e-4ff6-ba10-734d64143c1d.png", "task-photo-8d5feed4-d6a1-4ae9-9a72-387ccfda1dc5.jpg"); 
      return json; 
     } 
     catch (Exception ex) 
     { 
      return "{}"; 
     } 
    } 
} 


[ServiceContract] 
public interface INewsRest 
{ 
    [OperationContract] 
    [WebGet(ResponseFormat=WebMessageFormat.Json)] 
    string getHomePageNews1(); 
} 

и веб-конфигурации IS-

<system.serviceModel> 
<behaviors> 
    <serviceBehaviors> 
    <behavior name="NewsRestBehavior"> 
     <serviceMetadata httpGetEnabled="true" policyVersion="Policy15" /> 
     <serviceDebug includeExceptionDetailInFaults="false" /> 
    </behavior> 
    </serviceBehaviors> 
</behaviors> 
<services> 
    <service name="UPNews.WebServices.NewsRest" behaviorConfiguration="NewsRestBehavior"> 
    <endpoint address="" 
       binding="basicHttpBinding" 
       contract="UPNews.WebServices.INewsRest" /> 
    <endpoint address="mex" binding="mexHttpBinding" name="MetadataEndpoint" 
    contract="IMetadataExchange" /> 
    </service> 
</services> 
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 

но когда я тестирую эту услугу на WCF, он дает следующую ошибку. -

Error: Cannot obtain Metadata from http://localhost:57358/WebServices/NewsRest.svc/getHomePageNews1 If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.

The request failed with HTTP status 400: Bad Request.

Пожалуйста, расскажите, что здесь происходит.

Чтобы добавить MEX (обмен метаданных), вы можете добавить конфигурацию своего сервера, чтобы клиент мог получить сгенерированный WSDL. Что-то вроде этого:

<service name="UPNews.WebServices.NewsRest" behaviorConfiguration="NewsRestBehavior"> 
    <endpoint address="" 
      binding="basicHttpBinding" 
      contract="UPNews.WebServices.INewsRest" /> 
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
    </service>
