[Opening Guide]-detailed description of Entity Framework instances

I. Preface

Browsing the ADO. Net blog found that Entity Framework has made significant progress over the past few years, especially in the past one or two years. Ef4.1 introduces support for the new dbcontext API and code first. EF 4.3, released earlier this year, provides support for code first migration, which allows developers to easily optimizeCodeTo improve the database architecture. EF5 is now released and open-source. The new version supports enumeration, spatial data types, table valued functions, and some important performance and Visual Studio Tools. As the next major version of Entity Framework, ef6 plans to implement Task-based synchronization, support for stored procedures and functions in code first, and custom code first conventions.

Ii. Why?

The main reasons for writing this series are as follows:

1. As described in the preface, Entity Framework is developing rapidly and provides more and more functions, becoming more and more powerful and mature. Be familiar with and use entity framework to create and maintain applicationsProgramAchieve twice the result with half the effort.

2. I wrote "Entity Framework 4 in action Reading Notes" last year. It is only a matter of fact that I have not finished writing at the time and personal level. One year later, I wrote a blog post on Entity Framework to share my experience in learning and using entity framework over the past year.

3. You can write a blog post to gain a deep understanding of the learning content, help you master and use it, and share it with you for further discussion and common progress.

Iii. How to Write

1. For example, each article in this seriesArticleUse as many instances as possible to explain the Entity Framework. The basic structure of each article includes EF knowledge points and program code. The structure of the article varies depending on the content of the article.

2. Because I work during the day and often work overtime at night, the update frequency of the article will not be too fast, but the quality must be guaranteed.

Iv. Learning Resources

1. First, provide the following books:

(1) Entity Framework 4.1 expert's cookbook

(2) programming Entity Framework codefirst

(3) programming Entity Framework dbcontext

(4) programming Entity Framework 2nd Edition

2. provide another URL:
