什么是的DbContext和ObjectContext的之间的区别 [英] What's the difference between DbContext and ObjectContext

问题描述

从MSDN：

重新presents的单位按工作及库模式的组合，使您能够查询数据库，并组合在一起，然后将写回店为单位的变化。的DbContext在概念上类似于ObjectContext的。

Represents a combination of the Unit-Of-Work and Repository patterns and enables you to query a database and group together changes that will then be written back to the store as a unit. DbContext is conceptually similar to ObjectContext.

我虽然的DbContext只处理连接到数据库和对数据库工作线程的数量。

I though DBContext only handle the connection to the DB and the number of threads working against the DB.

现在我明白它包含了跟踪machanisem？我认为这是在ObjectContext的。

Now I understand it contains the tracking machanisem? I thought this was in the ObjectContext.

那么，什么是（用简单的英语）它们之间的区别呢？

So what is (in plain english) the difference between them?

推荐答案

的DbContext是ObjectContext类，这是奠定差不多吧上的ObjectContext之上的轻量级版本（甚至还有一个办法，从刚刚得到的ObjectContext的的DbContext）。这也是很多更容易使用，国际海事组织，使CRUD操作一个sinch。

DbContext is a lightweight version of the ObjectContext class, which is laid almost right on top of ObjectContext (there is even a way to get to the ObjectContext from just the DbContext). It's also a lot easier to use, IMO, and makes CRUD operations a sinch.
