Create a WCF service using the Entity Framework and consume after hosting it in IIS
----------------------------------------------------------------------------------------------------------------
Step1:Create table

USE [Chinna]
GO

/****** Object:  Table [dbo].[Student]    Script Date: 21-10-2014 12:06:31 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[Student](
[id] [int] IDENTITY(1,1) NOT NULL,
[Name] [nvarchar](50) NULL,
[age] [int] NULL,
 CONSTRAINT [stu_pk] PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO



step2:create procedures for inser,update,delete

Insert

USE [Chinna]
GO

/****** Object:  StoredProcedure [dbo].[Insert_student]    Script Date: 21-10-2014 12:08:20 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

create procedure [dbo].[Insert_student]
(
@Name nvarchar(50),
@age int
)
as
begin
insert into Student(Name,age) values(@Name,@age);
end

GO

Update

USE [Chinna]
GO

/****** Object:  StoredProcedure [dbo].[Update_student]    Script Date: 21-10-2014 12:09:10 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

create procedure [dbo].[Update_student]
(
@id int,
@Name nvarchar(50),
@age int
)
as
begin
update Student set Name=@Name,age=@age where id=@id;
end

GO


Delete
USE [Chinna]
GO

/****** Object:  StoredProcedure [dbo].[Delete_student]    Script Date: 21-10-2014 12:09:56 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

create procedure [dbo].[Delete_student]
(
@id int
)
as
begin
delete from Student where id=@id;
end

GO



Step3:go to vs run as administrator -->file-->new-->class lib-->Studentclaslibr-->ok

Remove -class1.cs file
add-->addnewitem--->wcf service-->ok
---goto solution explorer --->addnew item-->select ado.net entity frmae work-->StudentModel.edmx--->ok


---->select --generate from database

click Next

click Next

select the tables and sp's

click finish

 mapping the stored procedured

rc-->student entity

create the interface for service

implement the iservice in service class

host the wcf service using iis


add-->add new item-->wcf service-->wcf servicehost in the same path-->ok

add the studentclasslibr.dll to the host

and create the iis path to the wcfservice host and 

service is created now
