如何首先使用代码在已创建的数据库中创建ASP.net身份表？

我的应用程序已经开发了大约一个月。 我现在决定使用ASP.NET Identity。 我已经有了身份的视图模型，但需要创建表。 我在想，如果我有视图模型，我不确定为什么我没有表格？ 我使用自己的自定义上下文在初始化程序中删除了create，我只需要知道如何让EF为用户和角色构建包含的Identity表？ 我环顾四周，发布的答案似乎都不是我需要的？

Answer 1

考虑迁移

如果适用，您需要考虑构建迁移 ，这将允许您生成（并可能执行）必要的脚本，以在数据库中创建适当的表或更改。

默认情况下，您应该具有某种类型的ApplicationDbContext类，它类似于以下内容，用于定义“安全相关”数据库：

 public class ApplicationDbContext : IdentityDbContext { public ApplicationDbContext() : base("DefaultConnection", false) { } // Other code omitted for brevity } 

然后，您只需要在程序包管理器控制台中运行Enable-Migrations命令：

 Enable-Migrations 

这应该在您的应用程序中生成一个Migrations文件夹，其中包含控制迁移执行方式的各种配置文件以及InitialCreate迁移。 如果您之前在应用程序中有一些与Code-First相关的代码，则可能只会出现这种情况，如果没有，请不要担心。 然后，您可以尝试运行Update-Database命令，该命令应对您的数据库执行任何迁移（包括初始迁移）：

 Update-Database 

更新数据库后，您可以继续对模型进行更改，只需通过Add-Migration命令和以前的Update-Database命令创建和执行新的迁移：

 Add-Migration "AddedAnotherPropertyToFoo" Update-Database 

Answer 2

所以经过一番阅读后，我得到了答案。 我所要做的就是最终从ASP.NET Identity运行register方法并创建所有表。

Answer 3

在您的数据库上运行此SQL脚本并完成它。

如果您不想启用迁移，可能只是针对数据库运行ASP.NET Identity Sql Scripts：
