AspNet Core3身份配置 [英] AspNet Core3 Identity configuration

问题描述

我正在尝试遵循一些过时的AspNet Core 1.1教程项目(当我使用Visual Studio 2019预览版2.0时，和.net core v3.0.0-preview9已安装)

I'm trying to follow a little bit out of date tutorial project for AspNet Core 1.1 (while I'm using Visual Studio 2019 preview 2.0, and .net core v3.0.0-preview9 installed)

我已经有一个包含几个由EntityFrameworkCore3.00-preview创建的表的数据库，效果很好.

I already have a database with a couple of tables created by EntityFrameworkCore3.00-preview, it works fine.

现在我正在尝试将自动处理添加到项目中所以我从IdentityDbContext派生我的数据库上下文类，

Now I'm trying to add autorization into project So I derive my database context class from IdentityDbContext,

公共类MyDbContext:IdentityDbContext

代替

公共类WorldContext:DbContext

进行添加迁移和更新数据库，并在数据库中看到许多新表

make add-migration and update-database and in database I see many new tables

这时我的应用程序可以启动，但是在我添加一行的那一刻

At this point my application could start, but at the very moment as I added a line

services.AddIdentity< IdentityUser，IdentityRole>();

到Startup.cs中的ConfigurationServices

to ConfigurationServices in Startup.cs

应用程序崩溃并显示以下消息:

application crashes with message:

如果我实施公共类MyUserStore:IUserStore< IdentityUser>

并添加一行 services.AddScoped< IUserStore< IdentityUser> ;, MyUserStore>();

到ConfigurationServices，我收到有关

to ConfigurationServices, I receive next error about

无法解析类型为'Microsoft.AspNetCore.Identity.IRoleStore'的服务

Unable to resolve service for type 'Microsoft.AspNetCore.Identity.IRoleStore

，依此类推，尽管在本教程中，所有这些接口的实现都没有.在我看来，我在配置服务中做错了什么?

and so on, though in tutorial there is nothing about implementation all those interfaces. It's seems to me that I do something wrong in configuration services?

推荐答案

您需要添加 AddEntityFrameworkStores< TContext>():

services.AddIdentity<IdentityUser, IdentityRole>()
    .AddEntityFrameworkStores<WorldContext>();

FWIW，ASP.NET Core 1.1并非有点过时".引用该版本的文档已经过时，几乎没有用.2.X发生了很大变化，而3.X发生了很大变化.您应该找到其他文章/教程.

FWIW, ASP.NET Core 1.1 is not "a little outdated". Documentation referencing that version is so outdated as to be virtually useless. So much changed in 2.X, and even more in 3.X. You should find a different article/tutorial.
