.Net EF Identity 表未显示在数据库中获取无效的对象名称“AspNetUsers”异常

问题描述

我正在尝试对我的 webapi 进行登录调用，这导致以下异常。身份表未显示在 Microsoft sql Server 中。我试过使用迁移/更新数据库命令。

我还尝试制作第二个项目，其中我首先添加了 EF，但当我开始添加其他表时，它们不会出现。

这是我在 stackoverflow 上的第一篇文章，如果不让我知道，我希望它符合标准，我将编辑/添加需要的内容。

控制器登录：

is:unresolved age:-1w

ApplicationDbContext：

[AllowAnonymous]
    [HttpPost]
    public async Task<ActionResult<String>> Createtoken(LoginDTO model)
    {
        var user = await _userManager.FindByIdAsync(model.Email);
        if (user != null)
        {
            var result = await _signInManager.CheckPasswordSignInAsync(user,model.Password,false);
            if (result.Succeeded)
            {
                string token = GetToken(user);
                return Created("",token); //returns only the token
            }
        }
        return BadRequest();
    }

        modelBuilder.Entity<CustomerSale>().HasOne(p => p.Ticket).WithMany().HasForeignKey(p => p.TicketId);*/


        //seeding the db
        modelBuilder.Entity<Ticket>().HasData(
            new Ticket { Id = 1,Name = "Eurovisiesongfestival",EventDate = new DateTime(2021,12,24) },new Ticket { Id = 2,Name = "TomorrowLand",EventDate = new DateTime(2022,2,14) });

        //Shadow property can be used for the foreign key,in combination with anonymous objects
        modelBuilder.Entity<Artist>().HasData(
            new { Id = 1,Name = "Netsy",TicketId = 2 },new { Id = 2,Name = "Eminem",TicketId = 1 },new { Id = 3,Name = "Afro",new { Id = 4,Name = "Rihanna",new { Id = 5,Name = "Bruno Marz",TicketId = 1 }
            );
    }

    public DbSet<Ticket> Tickets { get; set; }
    public DbSet<Customer> Customers { get; set; }
}
