Error creating wcf .svc service

Question

I have created following svc service given below-

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();
}

and web config configuration 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" />

but when I am testing this service on WCF test client it gives following error.-

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.

Please tell whats wrong happening here.

You must add to your server configuration to allow MEX (meta data exchange) so that the client can retrieve the generated WSDL. Something like this:

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