how to stop dotnet ef migrations adding from creating unnecessary additional fields-CodePudding

This is a barebones application with only one class: AppUser having only (Id, FirstName, LastName, Phone1, Phone2, KnownAs, EmailAddress, Question, Answer, and IsTrialMode.

There are no other tables!

DataContext is only:

    public class DataContext : DbContext
{
    public DataContext(DbContextOptions options) : base(options)
    {
    }

    public DbSet<AppUser> Users { get; set; }
}

When I do a dotnet ef migrations add command, the migrations file contains:

            migrationBuilder.CreateTable(
            name: "Users",
            columns: table => new
            {
                Id = table.Column<int>(type: "int", nullable: false)
                    .Annotation("SqlServer:Identity", "1, 1"),
                FirstName = table.Column<string>(type: "nvarchar(max)", nullable: true),
                LastName = table.Column<string>(type: "nvarchar(max)", nullable: true),
                Phone1 = table.Column<string>(type: "nvarchar(max)", nullable: true),
                Phone2 = table.Column<string>(type: "nvarchar(max)", nullable: true),
                KnownAs = table.Column<string>(type: "nvarchar(max)", nullable: true),
                EmailAddress = table.Column<string>(type: "nvarchar(max)", nullable: true),
                Question = table.Column<string>(type: "nvarchar(max)", nullable: true),
                Answer = table.Column<string>(type: "nvarchar(max)", nullable: true),
                IsTrialMode = table.Column<bool>(type: "bit", nullable: false),
                UserName = table.Column<string>(type: "nvarchar(max)", nullable: true),
                NormalizedUserName = table.Column<string>(type: "nvarchar(max)", nullable: true),
                Email = table.Column<string>(type: "nvarchar(max)", nullable: true),
                NormalizedEmail = table.Column<string>(type: "nvarchar(max)", nullable: true),
                EmailConfirmed = table.Column<bool>(type: "bit", nullable: false),
                PasswordHash = table.Column<string>(type: "nvarchar(max)", nullable: true),
                SecurityStamp = table.Column<string>(type: "nvarchar(max)", nullable: true),
                ConcurrencyStamp = table.Column<string>(type: "nvarchar(max)", nullable: true),
                PhoneNumber = table.Column<string>(type: "nvarchar(max)", nullable: true),
                PhoneNumberConfirmed = table.Column<bool>(type: "bit", nullable: false),
                TwoFactorEnabled = table.Column<bool>(type: "bit", nullable: false),
                LockoutEnd = table.Column<DateTimeOffset>(type: "datetimeoffset", nullable: true),
                LockoutEnabled = table.Column<bool>(type: "bit", nullable: false),
                AccessFailedCount = table.Column<int>(type: "int", nullable: false)
            },
            constraints: table =>
            {
                table.PrimaryKey("PK_Users", x => x.Id);
            });

This is clearly NOT what I was expecting.
What is causing this; how to make it stop?

Thanks in advance. "Chuck"

CodePudding user response：

From your migration file, the additional properties seem to be the IdentityUser class default properties.

Be sure your AppUser does not extend IdentityUser or IdentityUser<T> class:

public class AppUser
{
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Phone1 { get; set; }
    public string Phone2 { get; set; }
    public string KnownAs { get; set; }
    public string Question { get; set; }
    public string Answer { get; set; }
    public string EmailAddress { get; set; }
    public bool IsTrialMode { get; set; }
}
