WCF Self Hosting with Example and Source Code

Introduction

Windows Communication Foundation (WCF) is a programming interface as part of .NET Framework.

Using 3 types we can host service in WCF

1          1. Self-Hosting

2           2 .IIS Hosting

3          3. WAS

In this article I will tell you how to create WCF Service and how to host using self-hosting and how to consume this service in Web Application. In this article I will discuss about self-hosting your WCF Service, because it’s the most flexible and easiest way to host WCF services. Another way to host WCF Service is using Internet Information Services(IIS). IIS will be explained in my other article.

Part-1   Create the Service

Open Visual Studio 2010 

Step 1: Select the new Empty Solution and give name WCFProject.

Step 2: Then add new Class Library Project and give name SaleClassLibrary.

Step 3: Then add reference of System.ServiceModel and System.Runtime.Serialization into that project.

Step 4: Then add new Interface ISaleService.

//

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

using System.Collections.Generic;

using System.Runtime.Serialization;

using System.ServiceModel;

 [ServiceContract]

    interface ISaleService

    {

        [OperationContract]

         bool InsertCustomer(Customer obj);

        [OperationContract]

        List<Customer> GetAllCustomer();

        [OperationContract]

        bool DeleteCustomer(int Cid);

        [OperationContract]

        bool UpdateCustomer(Customer obj);    

    }

  [DataContract]

   public class Customer

    {

        [DataMember]

        public int CustomerID;

        [DataMember]

        public string CustomerName;       

        [DataMember]

        public string Address;

        [DataMember]

        public string EmailId;

    }

Step 5: And write the following code in the SaleService.cs file: 

SaleService.cs page:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

using System.Collections.Generic;

using System.Configuration;

using System.Data;

using System.Data.SqlClient;

public class SaleService : ISaleService

    {

        public bool InsertCustomer(Customer obj)

        {

            cutomerList.Add(obj);

            return true;

        }

        public List<Customer> GetAllCustomer()

        {

            return cutomerList;

        }

        public bool DeleteCustomer(int Cid)

        {

            var item = cutomerList.First(x => x.CustomerID == Cid);

            cutomerList.Remove(item);

            return true;

        }

        public bool UpdateCustomer(Customer obj)

        {

            var list = cutomerList;

            cutomerList.Where(p => p.CustomerID ==

            obj.CustomerID).Update(p => p.CustomerName = obj.CustomerName);

            return true;

        }

      public static  List<Customer> cutomerList = new List<Customer>()

         {

        new Customer {CustomerID = 1, CustomerName="Sujeet",

        Address="Pune", EmailId="test@yahoo.com" },

        new Customer {CustomerID = 2, CustomerName="Rahul",

        Address="Pune", EmailId="test@yahoo.com" },

        new Customer {CustomerID = 3, CustomerName="Mayur",

        Address="Pune", EmailId="test@yahoo.com"}

         };

      

    } 

Step 6: Build your Class library.

Step 7: Add new Console Application in the same solution SaleServiceSelfHosting
