Question

我正在开发一个有两个解决方案的项目，第一个是桌面应用程序，管理员可以管理所有管理，他可以添加用户，删除它们等。在web部分，用户可以注册，登录等。我无法使asp身份使用我自己的数据库，每当我更改连接字符串时，我都会收到以下错误 [无效的对象名称'dbo.AspNetUsers'。] 表示没有这样的表格我以为asp.net身份会自动创建那些表。我需要手动完成吗？手动编写表格并使asp.net标识使用后会更好。这可能吗？

最后我用sql管理工作室解决了这个问题。我用sqlms打开了我在AppData文件夹中的mdf文件，然后右键单击新创建的数据库，悬停在任务上并单击生成脚本。我标记了所有表格，并创建了一个脚本。然后我用我的数据库运行该脚本，它现在运行良好。这是脚本：

Answer 2

听起来像你有两个DbContext。如果您希望Identity为您生成这些表格，您可能应该只从DbContext继承IdentityDbContext并且您将全部设置完毕。您可以查看有关如何Merge MyDbContext with IdentityDbContext。

的Stackoverflow问题

您还需要添加迁移。

你可能应该知道的是IdentityDbContext不是黑魔法，它只是一个DbContext，只有一些预先设定的DbSet你可以检查来源here。
