Use the web service to get a list of objects

Question

Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata.

I have searched long and hard but found nothing that helped yet. Where I wrong? I really do not know what to do. I wrote all the details below. I've tried and did not succeed.

my code :

[ServiceContract]

    public interface IUsersService
    {
        [OperationContract]
        void DoWork();

        [OperationContract]
        List<User> GetUsers();
    }




 public class UsersService : IUsersService
    {
        public void DoWork()
        {

        }

        public List<User> GetUsers()
        {
            var users=new List<User>();
            var sqlConnection =
                new SqlConnection(conString);
            var sqlDataAdapter=new SqlDataAdapter("select * from users",sqlConnection);

            var dt = new DataTable();

            sqlDataAdapter.Fill(dt);

            foreach (DataRow dataRow in dt.Rows)
            {
                users.Add(new User(dataRow["Name"].ToString()));
            }

            return users;
        }
    }

    public class User
    {
        public string UserName { get; set; }

        public User(string name)
        {
            UserName = name;
        }
    }

web config :

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="JuventusNewsWebService.UsersServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="JuventusNewsWebService.UsersServiceBehavior"
          name="JuventusNewsWebService.UsersService">
        <endpoint address="" binding="basicHttpBinding" contract="JuventusNewsWebService.IUsersService">
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
  </system.serviceModel>

error :

could It be you are missing host with in services :

 <services>
      <service name="WcfServiceLibrary1.UsersService">
        <host>
          <baseAddresses>
            <add baseAddress = "http://localhost:8733/Design_Time_Addresses/WcfServiceLibrary1/UsersService/" />
          </baseAddresses>
        </host>
....
  </service>
    </services>

Generally you don't need to define the baseAddress if you host the service in IIS which takes care of this.

While the suggestion from the error message might be working, however, please be aware that the solution is for legacy Web service. For WCF, you don't need that setting.

For more detail, you have have a look this CodeProject article. http://www.codeproject.com/Articles/627240/WCF-for-the-Real-World-Not-Hello-World

For your problem, please check it the example codes particularly app.config deal with relative url and activate the service.
