Renamed default tables but AspNetusers Table Still Getting Created - asp.net

Question

I am working with ASP.NET identity. I renamed the default tables using the following code.
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<IdentityUser>().ToTable("Users");
modelBuilder.Entity<IdentityRole>().ToTable("Roles");
modelBuilder.Entity<IdentityUserRole>().ToTable("UserRoles");
modelBuilder.Entity<IdentityUserClaim>().ToTable("UserClaims");
modelBuilder.Entity<IdentityUserLogin>().ToTable("UserLogins");
}
}
}
But when I run my app, AspnetUsers is still created but with a single column named 'Id'. This table is being populated along with the new "Users" table. Why? And how do I stop this behavior.
I see the same question asked here, but without a good response: Identity 2.0 Code First Table Renaming
I hope I am not violating StackOverflow's guidelines in reasking this question/// if so apologies in advance!

Stumbled across this post when looking for a quick solution - now I've dug a bit through the code and found the answer; maybe it helps someone.
I suppose you have overwritten the default IdentityUser class, right?
public class ApplicationUser : IdentityUser
{
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
...
In that case, you'll have to exclude the default IdentityUser from the ModelBuilder:
protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
//modelBuilder.Entity<IdentityUser>().ToTable("Users", "dbo"); // we have overwritten IdentityUser, so no more need for the empty AspNetUsers table
modelBuilder.Entity<ApplicationUser>().ToTable("Users", "dbo"); // Use ApplicationUser instead
modelBuilder.Entity<IdentityRole>().ToTable("Roles", "dbo");
