[英]Dependency injection fails for .Net Core 2.1 customized IdentityUI
The new .Net Core 2.1 Identity is very confusing. 新的.Net Core 2.1身份非常令人困惑。
Here is my code: 这是我的代码:
STARTUP.CS 启动文件
services.AddIdentity<User, IdentityRole>(options => options.Stores.MaxLengthForKeys = 128)
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultUI()
.AddDefaultTokenProviders();
DBCONTEXT 数据库上下文
public class ApplicationDbContext : IdentityDbContext<User>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
}
But I got this error: 但是我得到了这个错误:
InvalidOperationException: No service for type 'Microsoft.AspNetCore.Identity.UserManager`1[Microsoft.AspNetCore.Identity.IdentityUser]' has been registered.
InvalidOperationException:没有注册类型为'Microsoft.AspNetCore.Identity.UserManager`1 [Microsoft.AspNetCore.Identity.IdentityUser]'的服务。
What I'm doing wrong? 我做错了什么?
User
has been registered with Identity Framework as the extended user identity model. User
已向Identity Framework注册为扩展的用户身份模型。
However, the exception message implies that somewhere in the project has a class dependent on UserManager<IdentityUser>
, which would have been the default from the template. 但是,异常消息表示项目中某处具有依赖于
UserManager<IdentityUser>
的类,该类将是模板中的默认类。
Since the default has been extended, then where ever there is reference to the default UserManager<IdentityUser>
would need to be updated to UserManager<User>
由于扩展了默认值,因此
UserManager<IdentityUser>
引用默认值的UserManager<IdentityUser>
都需要更新为UserManager<User>
