EF 6.x中的DbContext发生器的目的 [英] purpose of EF 6.x DbContext Generator

问题描述

我有我使用LINQ到SQL建立一个web应用程序，我期待将它升级到Linq到EF。我已经看了一些教程，基本上在数据库中的第一个场景，您创建一个ADO.NET实体数据模型，并从那里选择模型（非常类似于LINQ到SQL）包括哪些表。现在添加新项窗口上，我看到有这么包括创造一个EF 6.x中的DbContext发电机的另一种选择。

I have a web app that I built using Linq-to-SQL and I'm looking to upgrade it to Linq-to-EF. I've looked at some tutorials and basically in the database-first scenario, you create an ADO.NET Entity Data Model and from there select which tables to include in the model (very similar to linq-to-sql). Now on the Add New Item window, I see that there's another option that consists of creating an EF 6.x DbContext Generator.

相比，创建只是一个ADO.NET实体数据模型（窗口的第一个选项）什么的DbContext发电机的目的，什么是的DbContext发生器？这似乎是创建一个文本文件;我该怎么办呢？

What's the purpose of DbContext Generator compared to creating just an ADO.NET Entity Data Model (first option of window), and what is the DbContext Generator for? It seems to create a text file; what should I do with it?

推荐答案

如果你已经有一个数据库，第一个选项，是更好地考虑到的方法是非常相似的，你在LinqToSQL已经工作的人。
该.edmx文件也可以为您提供您的数据库的图形可视化，而且你不必担心任何事情。

If you already have a database, the first option is better, given that the approach is very similar to the one you are already working in LinqToSQL. The .EDMX file also can provide you a graphical visualization of your database, and you don't have to worry about anything else.
