好的，通过添加Microsoft.AspNetCore.Identity.UI"来帮助您NuGet 包.现在我遇到了另一个错误.:-/我无法理解这个.
Ok, that help by adding "Microsoft.AspNetCore.Identity.UI" NuGet package. Now I have run into another error. :-/ I can't make sense of this one.
services.AddDefaultIdentity<ApplicationUser>()
.AddRoles<IdentityRole<Guid>>()
.AddEntityFrameworkStores<ApplicationContext, Guid>()
.AddDefaultTokenProviders();
第一行的错误现在消失了.但是现在这里的第 3 行出现了新错误，AddEntityFrameworkStore
The error on the first line is gone now. But now new error on 3rd line here, "AddEntityFrameworkStore<ApplicationContext, Guid>()". The error message is --> "IdentityBuilder" does not contain a definition for "AddEntityFrameworkStores" & no accessible extension method "AddEntityFrameworkStores" accepting a first argument of type "IdentityBuilder" could be found (are you mising a using directive or an assembly reference?).
甚至不确定 NuGet 包是做什么的AddEntityFrameworkStores"；来自 &从 1 版到 3.1 版也有什么变化.
Not even sure what NuGet package does this "AddEntityFrameworkStores" come from & what have changed from version 1 to 3.1 either.
推荐答案
您需要添加对 Microsoft.AspNetCore.Identity.UI nuget 包 以使用 AddDefaultIdentity.但是，如果您不想迁移到 Identity Razor 类库，我认为您仍然可以在核心 3.1 中使用 .AddIdentity.如果您确实想迁移到 RCL，从 2.0 到 2.1 的迁移文档可能是一个不错的起点:https:///docs.microsoft.com/en-us/aspnet/core/migration/20_21?view=aspnetcore-3.1#changes-to-authentication-code
You would need to add a reference to the Microsoft.AspNetCore.Identity.UI nuget package in order to use AddDefaultIdentity. But if you don't want to migrate to the Identity Razor Class Library I think you can still use .AddIdentity<ApplicationUser, IdentityRole>() in core 3.1. If you do want to migrate to the RCL, the Migration documentation for 2.0 to 2.1 might be a good starting place:
https://docs.microsoft.com/en-us/aspnet/core/migration/20_21?view=aspnetcore-3.1#changes-to-authentication-code
--- 编辑---
我已经将一些网站从 1.1 迁移到 3.1，我发现最简单的方法是:
I've migrated a few sites from 1.1 to 3.1 and the easiest way I have found to do it is this:
- 将整个解决方案移至备份文件夹(确保将源代码管理文件保留在原处).
- 在您的原始位置创建一个与 3.1 完全相同的名称的新应用程序.我在 VS 2019 中使用Web 应用程序(模型-视图-控制器)"模板并将身份验证更改为个人用户帐户".
- 将其提交给源代码管理，以便您可以查看所做的更改.
- 将您的所有页面、视图控制器和其他代码复制到新应用中.
- 重新添加任何丢失的 nuget 包.
- 您可能需要对复制的代码进行一些更改，但您可以使用源代码管理和迁移文档中的更改作为参考点.
它仍然需要很多才能使其正常工作，但否则您将需要阅读每个迁移文档，从 1.x 到 2.0 的文档，一直到 3.0 到 3.1 的文档.
It still takes a lot to get it working but otherwise you will need to go through every migration doc starting with the one for 1.x to 2.0 all the way through the doc for 3.0 to 3.1.
