Operation Contracts not Generated in Windows Form Application from a WCF Library Project.

Hi all.

I created a WCF library project. I have tested it n the WCF Test Client and everything works just as expected.

When I add the service as a service reference for a Windows Form client, for some unknown reason, I can only get one Operation Contract (defined in IExam.cs called

bool AddExam(...) 

despite having others exposed from the service side!

Here are my contracts:

IUser.cs

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

namespace Examination
{

    [ServiceContract]
    public interface IUser
    {
        [OperationContract]
        bool Login(string userName, string passWord);
        [OperationContract]
        List<User> GetUsers();
    }

    [DataContract]
    public class UserData
    {
        [DataMember]
        public string UserName;

        [DataMember]
        public string password;
    }


}

IExam.cs

using System;
... //Just as before.

namespace Examination
{
    [ServiceContract]
    public interface IExam
    {
        [OperationContract]
        bool AddExam(string unitCode, string unitName, String examDate, double duration,
            string instructions, string university, string course, int userID);
    }

    [DataContract]
    public class ExamData
    {
        [DataMember]
        public int ExamID;

        [DataMember]
        public string UnitCode;

        [DataMember]
        public string UnitName;

        [DataMember]
        public string ExamDate;

        [DataMember]
        public double Duration;

        [DataMember]
        public string Instructions;

        [DataMember]
        public string University;

        [DataMember]
        public string Course;

        [DataMember]
        public int UserID;
    }
}

ISection.cs

using System;
... //Just as before.

namespace Examination
{
    [ServiceContract]
    public interface ISection
    {
        [OperationContract]
        bool AddSection(string sectionName,int marks, int examId);

        List<Section> GetSections();

    }

    [DataContract]
    public class SectionData
    {
        [DataMember]
        public int SectionID;

        [DataMember]
        public string SectionName;


        [DataMember]
        public int Marks;

        [DataMember]
        public int ExamId;

    }
}

IQuestion.cs

using System;
... //Just as before.

namespace Examination
{
    [ServiceContract]
    public interface IQuestion
    {
        [OperationContract]
        bool AddQuestion(string questionPhrase, byte[] diagram, int marks, int sectionId, string answerPhrase, byte[] answerDiagram);

        [OperationContract]
        List<Question> GetQuestions();
    }

    [DataContract]
    public class QuestionData
    {
        [DataMember]
        public string QuestionPhrase;
        [DataMember]
        public byte[] QuestionDiagram;

        [DataMember]
        public int Marks;

    }
    [DataContract]
    public class Answer
    {
        [DataMember]
        public string AnswerPhrase;
        [DataMember]
        public byte[] AnswerDiagram;
    }
}

Service.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Security.Cryptography;
using System.ServiceModel;
using System.Text;


namespace Examination
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in both code and config file together.
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
    public class Service : IUser, IExam, ISection, IQuestion
    {

        public bool Login(string userName, string password)
        {
           ...
        }

        private UserData GetUserData(string userName)
        {
            ...
        }

        public bool AddExam(string unitCode, string unitName, string examDate, double duration, string instructions, string university, string course, int userID)
        {
           ...
        }



        private ExamData GetExamData(string unitCode)
        {
            ...

        }


        public bool AddSection(string sectionName, int marks, int examId)
        {
            ...
        }

        

        public bool AddQuestion(string questionPhrase, byte[] questionDiagram, int marks, int sectionId, string answerPhrase, byte[] answerDiagram)
        {
            ...
        }


        public List<Exam> GetExams()
        {
            ...
        }


        public List<User> GetUsers()
        {
            ...
        }


        public List<Section> GetSections()
        {
            ...
        }


        public List<Question> GetQuestions()
        {
            ...
        }
    }
}

            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

And when I create the proxy to start calling the Operation Contracts, I can only get

the Operation Contract defined:

bool AddExam(...);

Why are others not available on the client side and what can I do to make them available? I am totally stuck here. Please help me. I have looked through the internet for a solution for this but I just can't find any.
