Custom Identity User MVC 5 生成两个用户表

Question

我正在尝试自定义我的 IdentityUser 以将主键生成为整数并更改表名。 问题是：正确生成了主键，并且所有标准表都是由迁移正确创建的，使用新名称，但用户除外。当我应用 Add-Migration 命令时，它会返回两个“用户表”。

这是我的代码。

我的自定义身份类

public class User : IdentityUser<int, CustomUserLogin, CustomUserRole, CustomUserClaim>
{
}
public class CustomUserRole : IdentityUserRole<int> { }
public class CustomUserClaim : IdentityUserClaim<int> { }
public class CustomUserLogin : IdentityUserLogin<int> { }

public class CustomRole : IdentityRole<int, CustomUserRole>
{
    public CustomRole() { }
    public CustomRole(string name) { Name = name; }
}

我的 ApplicationDbContext

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, CustomRole, int, CustomUserLogin, CustomUserRole, CustomUserClaim>
{
    public ApplicationDbContext() : base("CONNSTRING") { }


    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<User>().ToTable("Users", "dbo");
        modelBuilder.Entity<CustomRole>().ToTable("Role","dbo");
        modelBuilder.Entity<CustomUserRole>().ToTable("UserRole", "dbo");
        modelBuilder.Entity<CustomUserLogin>().ToTable("UserLogin", "dbo");
        modelBuilder.Entity<CustomUserClaim>().ToTable("UserClaims", "dbo");


    }
}

EF 生成的脚本，你可以看到生成了两个“用户表”：标准的一个“AspNetUsers”和我的自定义一个“用户”。

附加信息： 该应用程序使用“AspNetUsers”表作为主体。

感谢您的帮助。

我认为您必须像这样在 OnModelCreating 方法中将 IdentityUser 映射到您的新用户表。

modelBuilder.Entity<IdentityUser>()
                        .ToTable("Users", "dbo").Property(p => p.Id).HasColumnName("UserId");
