Identity 2.0 Code First Table Renaming

问题

I'm trying to rename the identity tables to Roles, Users, UserRoles, UserLogins and UserClaims. I partially succeeded doing and using the command Update-Table updates my database.

However I cant seem to be able to get rid off the AspNetUsers table, it always gets generated with only one column, the Id column, although I get another Users table with the full list of columns, and another Id column.

The script generated by Update-Database

And my db context:

namespace Carbon.Models {
    using System;
    using System.Data.Entity;
    using System.ComponentModel.DataAnnotations.Schema;
    using System.Linq;
using Microsoft.AspNet.Identity.EntityFramework;

public partial class CarbonEDM : IdentityDbContext<ApplicationUser> {
    public CarbonEDM()
        : base("name=CarbonDB") {
    }

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

    protected override void OnModelCreating(DbModelBuilder modelBuilder) {

        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<IdentityUser>().ToTable("Users", "dbo");
        modelBuilder.Entity<IdentityRole>().ToTable("Roles", "dbo");
        modelBuilder.Entity<IdentityUserRole>().ToTable("UserRoles", "dbo");
        modelBuilder.Entity<IdentityUserClaim>().ToTable("UserClaims", "dbo");
        modelBuilder.Entity<IdentityUserLogin>().ToTable("UserLogins", "dbo");

    }
}

}

回答1:

You must be inheriting from the IdentityUser class. (Do you have a custom user class that inherits from IdentityUser?). If that's the case, don't overwrite the table name for IdentityUser, but only for your custom user class. Assuming that your custom user class is ApplicationUser:

modelBuilder.Entity<ApplicationUser>().ToTable("Users");

delete or comment the following line

//modelBuilder.Entity<IdentityUser>().ToTable("Users", "dbo");
