ASP.NET MVC 3

Introduction 

this is my fist article but after reading this article you are getting what is entity framework 4.1 and why say it's to "code fist" and how it is make easy to do database work in your any .net application here i give you only one asp.net mvc 3 example but you can use that in same in you any .net application (like silverlight, wpf ,asp.net 4 etc)

benefits of mvc 3(here we are see)
1.no need to create database here database are automatable garneted by .net
2.no need to create view(page) for insert update and delete in application
3.mvc 3 is full support for HTML5 CSS3 and JQuery
  and many more

Background 

fist of all before reading this article you have to some basic knowledge of .net architectural, oops and asp.net mvc 3
basic software tool to run this simple application in you pc

1. visual studio 2010 
2. Asp.net mvc 3 tools
3. entity framework 4.1  

Using the code 

here we create one asp.net mvc 3 empty project

  1. fist start visual studio then select new project and select asp.net mvc 3 application give MyFistEF name to application

press ok that ask you which type of project you want to select empty project and view engine is Razor than press ok  button

then you need to add some class in to your model in you solution explorer right click to "Model" folder and add new class 

here we create  simple example for shop and book one shop have many book create one class "book"

using System;
using System.Linq;
using System.Text;
namespace MyFistEF.Models
{
  public   class Book
    {
        public int BookID { get; set; }
        public string BookName { get; set; }

        public string AuthorNAme { get; set; }
    }
}

same as book class create bookshop class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web; 
namespace MyFistEF.Models
{

    public class BookShop
    {
        public int BookShopId { get; set; }
        public string ShopName { get; set; }

        public IList<Book> BookList { get; set; }
    }
}

in shop class we take one IList for book that is for one shop have many book when in shop class we take one IList for book that is for one shop have many book

one lass class for DataConext build you project here  when application are run that time using data DataContext  class Entity fingermark automatically greatness database using that "DataContext" remember don't forget to inherit "Dbcontext" class data to over context class that need to  add "System.Data.Entity" namespace

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;
namespace MyFistEF.Models
{

    public class DataContext :DbContext
    {
        public DbSet<Book> Books { get; set; }
        public DbSet<BookShop> Shops { get; set; }

    }
} 

here Model work is over 
now add new Controllers  right click to "Controllers" and select add => Controller

giver name to this controller to "homeController" then template option select "controller with read/write actions and views, using Entity Framework" that is create view for insert update and list view for selected model class here we select "Book" model class then last select Date context class then press add  

you application is ready to run when application is run the entity framework is create data base and it's table automatically it's also give Pk and Fk  in to table and give relationship also
