Я пытаюсь создать некоторые роли для моего веб-приложения, но оно не работает из-за Tkey exception.
Я не знаю, как я могу это исправить. Я думаю, что есть проблема с моим Startup.cs.
Что бы я ни пытался добавить DefaultIdentity и добавить роли.
Startup.cs - В этой строке я получаю сообщение об ошибке:
services.AddDefaultIdentity<IdentityRole>().AddRoles<IdentityRole>().AddDefaultUI().AddEntityFrameworkStores<VerwaltungsprogrammContext>();
Это сообщение об ошибке:
AddEntityFrameworkStores может быть вызван только с пользователем, который является производным от IdentityUser

Ошибка:

Файл Seed.cs предназначен для создания некоторых ролей
Вот мой Seed.cs
namespace Verwaltungsprogramm
{
public static class Seed
{
public static async Task CreateRoles(IServiceProvider serviceProvider, IConfiguration Configuration)
{
//adding customs roles
var RoleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
var UserManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();
string[] roleNames = { "Admin", "Manager", "Member" };
IdentityResult roleResult;
foreach (var roleName in roleNames)
{
// creating the roles and seeding them to the database
var roleExist = await RoleManager.RoleExistsAsync(roleName);
if (!roleExist)
{
roleResult = await RoleManager.CreateAsync(new IdentityRole(roleName));
}
}
// creating a super user who could maintain the web app
var poweruser = new ApplicationUser
{
UserName = Configuration.GetSection("AppSettings")["UserEmail"],
Email = Configuration.GetSection("AppSettings")["UserEmail"]
};
string userPassword = Configuration.GetSection("AppSettings")["UserPassword"];
var user = await UserManager.FindByEmailAsync(Configuration.GetSection("AppSettings")["UserEmail"]);
if (user == null)
{
var createPowerUser = await UserManager.CreateAsync(poweruser, userPassword);
if (createPowerUser.Succeeded)
{
// here we assign the new user the "Admin" role
await UserManager.AddToRoleAsync(poweruser, "Admin");
}
}
}
}
}
