Microsoft WCF test client Error

Question

I am new to WCF services. I was browsing with some tutorials and got a simple program and tried to execute in WCF service application in c#. The code is shown below.

IService1.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WcfService1
{
    [ServiceContract]
    public interface IService1
    {
        int calculatedays(int day,int month,int year);
    }    
}

Service1.svc.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

 namespace WcfService1
 {
     public class Service1 : IService1
     {
         public int calculatedays(int day, int month, int year)
         {
             DateTime dt = new DateTime(year, month, day);
             int datetodays = DateTime.Now.Subtract(dt).Days;
             return datetodays;
         }  
     }
}

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>

when i run the application its giving the error as

Error: Cannot obtain Metadata from http://localhost:2049/Service1.svc 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. For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error URI: http://localhost:2049/Service1.svc Metadata contains a reference that cannot be resolved: 'http://localhost:2049/Service1.svc'. The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error

How are you hosting the WCF service, can we see that code too — 3dd
you have not set your interface method signature to have the OperationContract attribute also... — Ahmed ilyas

Create One Host and add appconfig file inside the host program.Then write the following code inside appconfig.

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

    <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
    </system.web>
    <system.serviceModel>
    <services>
      <service name="WcfService1.Service1" behaviorConfiguration="maxBehaviour">
        <endpoint address="WcfService1" binding="netTcpBinding" contract="WcfService1.IService1">
        </endpoint>


        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:2049/"/>
            <add baseAddress="net.tcp://localhost:8090/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
   <behaviors>
      <serviceBehaviors>
        <behavior name="maxBehaviour">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

</configuration>

Add Reference of the Wcfservice1 project to this project.create one class and write the following code

        public static void Main()
        {
            using (ServiceHost host = new ServiceHost(typeof(WcfService1.Service1)))
            {
                host.Open();
                Console.WriteLine("Started Report Host");
                Console.ReadKey();
            }
        }
