I have a web application where I want to integrate ASP.NET Core Identity but after adding controllers and views and editing the _Layout.cshtml I get this error:
InvalidOperationException: No service for type 'Microsoft.AspNetCore.Identity.SignInManager`1[StrikeNet.EntityFramework.Entities.UserIdentity]' has been registered.
When I search for this error on Google or on here I only get the solution to rename all instances of IdentityUser to the name I have given, being UserIdentity. Also, many solutions say I should find it in the _LoginPartial.cshtml file.
The problem is, I don't have a file in my solution called _LoginPartial.cshtml and when I use the ctrl + F search tool and search for IdentityUser I also get no results.
Any ideas on what could be the remaining problem?
我认为您忘记将 Identity 添加到 Startup.cs 配置中:
services.AddIdentity<User, Role>(); // if you have roles
The problem is, I don't have a file in my solution called _LoginPartial.cshtml
I would suggest you create the asp.net core application with Identity template : Create ASP.NET Core web application -->Change Authentication --> choose Individual User Accounts . Ater visual studio help creating application with identity enabled , you can check the dbcontext , pages and startup file to find difference with your exist application . After copying the missing files , you can create your user entity inheriting from IdentityUser
:
public class UserIdentity: IdentityUser
{
}
Modify the ApplicationDbContext
:
public class ApplicationDbContext : IdentityDbContext<UserIdentity>
{
}
Modify Startup:
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(
Configuration.GetConnectionString("DefaultConnection")));
services.AddDefaultIdentity<UserIdentity>(options => options.SignIn.RequireConfirmedAccount = true)
.AddEntityFrameworkStores<ApplicationDbContext>();
And update the _LoginPartial :
@inject SignInManager<UserIdentity> SignInManager
@inject UserManager<UserIdentity> UserManager
