Question

信息
我想通过重新启动将我的ASP.NET Web页面项目“升级”到ASP.NET MVC项目，它只有几页而且对学习有好处。

问题
当前项目包含一些用户进行身份验证 ASP.NET在我的数据库中创建了几个表：

角色
配置文件
用户
...

但是当我使用MVC项目时，我看到它为验证提供了不同的表：

AspNetUserLogins
AspNetUserRoles
AspNetUser
...

问题
如何迁移用户或如何告诉ASP.net使用旧表？

Answer 1

您可能希望从MVC-Core中的数据库优先方法开始问候，但它与您目前所看到的有点不同，让我解释添加数据库的步骤：

安装实体框架：

运行Install-Package Microsoft.EntityFrameworkCore.SqlServer

要从现有数据库启用逆向工程，我们还需要安装其他几个软件包。

运行Install-Package Microsoft.EntityFrameworkCore.Tools –Pre
运行Install-Package Microsoft.EntityFrameworkCore.Design
运行Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design

现在对您的模型进行逆向工程：

运行以下命令以从现有模型创建模型数据库。如果您收到说明该术语的错误＆＃39;脚手架-的DbContext＆＃39;然后，不会将其识别为cmdlet的名称关闭并重新打开Visual Studio。

Scaffold-DbContext "Server=(localdb)\mssqllocaldb;Database=DataBaseName;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

逆向工程进程基于现有数据库的模式创建了实体类和派生上下文。实体类是简单的C＃对象，代表您将要查询和保存的数据。现在你可以创建一个DbContext类并开始使用你的数据库，到目前为止，关于数据库的问题已经结束，现在我建议你阅读Identity In Asp.NET Core。
