In this article I would like to share something regarding Entity Framework, how we can implement operations using Stored Procedures in Entity Framework. SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[Users]( [Uid] [int] IDENTITY(1,1) NOT NULL, [Fname] [nvarchar](50) NULL, [Lname] [nvarchar](50) NULL, [Email] [nvarchar](50) NULL, [Gender] [nvarchar](50) NULL, [Address] [nvarchar](50) NULL, CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED ( [Uid] 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 SET ANSI_NULLS ON GO Read More

CRUD Operations using Linq and Entity Framework in Asp.net and Cascade Delete using Linq Query In this series, I am going to tell you how to perform CRUD operations on a database using entity framework. I use database-first approach for this tutorial which supposes that you already have existing database and you want to automatically generate Entity Model based on this database. < !DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Introduction to Entity Framework

Category: ASP.NETENTITY FRAMEWORK Comments: One comment

ADO.NET Entity Framework is an Object/Relational Mapping (ORM) framework that enables developers to work with relational database. It enabling developers to deal with data as objects and properties.Using the Entity Framework, developers issue queries using LINQ, then retrieve and manipulate data as strongly typed objects using C# or VB.Net. The Entity Framework’s ORM implementation also provides services like change tracking, identity resolution, lazy loading, and query translation so that developers can focus on their application-specific business logic rather than the data access fundamentals. ADO.NET Entity Framework is targeted for developing Enterprise applications which can support MS SQL databases as well as other databases like as Oracle, DB2, MySql and many more. To learn entity framework first we need to know what is orm. I am going to give the overview of orm. What is O/RM? O/RM is an acronym that stands for object/relational mapping. Basically, an O/RM framework is used to persist model objects in a relational database and retrieve them. It uses metadata information to interface with the database. This way, your data-layer code knows nothing about the database structure. The O/RM tool becomes middleware that completely hides the complexity.Read More
