“ ApplicationDbContext”的部分声明不能指定不同的基类

Question

为什么会出现此错误：

  

“ ApplicationDbContext”的部分声明不能指定不同的基类

请在下面查看我的代码：

using System;
using System.ComponentModel.DataAnnotations;
using IssueTracker.Models;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;

namespace IssueTracker.Data
{
    public class ApplicationUser: IdentityUser 
    {
        [Required]
        [MaxLength(100)]
        public string FistName { get; set; }
        [MaxLength(100)]
        public string MiddleName { get; set; }
        [Required]
        [MaxLength(100)]
        public string LastName { get; set; }
        public bool IsActivated { get; set; } = false;
        public DateTime DateAdded { get; set; } = DateTime.Now;
    }

    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options) {}

        // Creating the roles
        protected override void OnModelCreating(ModelBuilder builder) 
        {
            base.OnModelCreating(builder);

            builder.Entity<ApplicationUser>().ToTable("User");
            builder.Entity<IdentityRole>().ToTable("Role");

            builder.Entity<IdentityUserRole<string>>().ToTable("UserRole");
            builder.Entity<IdentityUserClaim<string>>().ToTable("UserClaim");
            builder.Entity<IdentityUserLogin<string>>().ToTable("UserLogin");

            builder.Entity<IdentityRoleClaim<string>>().ToTable("RoleClaim");
            builder.Entity<IdentityUserToken<string>>().ToTable("UserToken");

            builder.Entity<IdentityRole>().HasData(
                new { Id = "1", name="Admin", NoralizeName = "ADMIN" },
                new { Id = "2", name="Customer", NoralizeName = "CUSTOMER" },
                new { Id = "3", name="Moderator", NoralizeName = "MODERATOR" }
            );
        }

        public DbSet<ProductModel> Products { get; set; }
    }
}

我正在使用Identity Framework并尝试重命名默认表名称。

如果我使用这个：

public class ApplicationDbContext : IdentityDbContext<IdentityUser>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options) {}
...

我没有收到任何错误，但我无法重命名

  

builder.Entity（）。ToTable（“ User”）;

这只是给我AspNetUsers

您能帮我吗？谢谢。

编辑 添加建议的解决方案后，我仍然无法将AspNetUser重命名为User。请查看下面的迁移：

migrationBuilder.CreateTable(
                name: "AspNetUsers",
                columns: table => new
                {
                    UserId = table.Column<string>(nullable: false),
                    UserName = table.Column<string>(maxLength: 256, nullable: true),
                    NormalizedUserName = table.Column<string>(maxLength: 256, nullable: true),
                    Email = table.Column<string>(maxLength: 256, nullable: true),
                    NormalizedEmail = table.Column<string>(maxLength: 256, nullable: true),
                    EmailConfirmed = table.Column<bool>(nullable: false),
                    PasswordHash = table.Column<string>(nullable: true),
                    SecurityStamp = table.Column<string>(nullable: true),
                    ConcurrencyStamp = table.Column<string>(nullable: true),
                    PhoneNumber = table.Column<string>(nullable: true),
                    PhoneNumberConfirmed = table.Column<bool>(nullable: false),
                    TwoFactorEnabled = table.Column<bool>(nullable: false),
                    LockoutEnd = table.Column<DateTimeOffset>(nullable: true),
                    LockoutEnabled = table.Column<bool>(nullable: false),
                    AccessFailedCount = table.Column<int>(nullable: false),
                    Discriminator = table.Column<string>(nullable: false),
                    FistName = table.Column<string>(maxLength: 100, nullable: true),
                    MiddleName = table.Column<string>(maxLength: 100, nullable: true),
                    LastName = table.Column<string>(maxLength: 100, nullable: true),
                    IsActivated = table.Column<bool>(nullable: true),
                    DateAdded = table.Column<DateTime>(nullable: true)
                },
                constraints: table =>
                {
                    table.PrimaryKey("PK_AspNetUsers", x => x.UserId);
                });
