推荐答案

In mvc你可以使用两种方法通过实体框架进行数据通信

1.代码第一种方法：首先在代码中你需要从临时级别创建类，在代码第一种方法中我们避免使用可视化设计器实体框架。换句话说，.EDMX文件被排除在解决方案之外。所以你现在可以完全控制上下文类和实体类。



2.数据库第一种方法：如果你已经创建了数据库并且你想要用户在您的应用程序中，您可以通过添加.Edmx文件来使用数据库优先方法。

注意：如果您对OOP和C＃编码知之甚少，则应使用数据库第一方法。

In mvc you can use two methods for data communication by entity framwork
1. Code first method : In code first you need to create class from the scratch level, In code first approach we avoid working with visual designer of entity framework. In other words the .EDMX file is excluded from the solution. So you now have complete control over the context class as well as the entity classes.

2. Database First method : If you have database already created and you want to user the same in your application then you can use database first method by adding .Edmx file.
Note : If you have less knowledge of OOP and C# coding the you should use database firs method.

Following links are the examples of code first and database firs method and you can search on the google as your requirement.
