I want to use Entity Framework + ASP Identity but I don't want EF to generate tables for me

Question
I have created new ASP MVC 5 app (with asp identity).
I use IdentityDbContext class to put all my domain objects inside.
public class SecurityContext : IdentityDbContext{
...
public DbSet<Country> Countries { get; set; }
When I first time created user all database tables were created (identity tables) including my Country table.
But now I added new table in database (created from Management Studio) and added in IdentityDbContext:
public DbSet<City> Cities { get; set; }
But when I run the app now I get error:
The model backing the 'SecurityContext' context has changed since the database was created. Consider using Code First Migrations to update the database.
If I delete all tables and run app again City will be created but I wan't to be more flexible.
So what I want to do is that I can create all database tables and to create my POCO classes in project later so I can use EF for data access.
I don't want EF to create classes for me (I feel more secure when connect those things alone).
Also (I know that it is possible but just don't know how) can I prevent asp Identity to create tables alone?
To sum whole question. I want to use EF but I want to create my database myself including Identity tables. How can I do this?
Accepted Answer
You can turn off the EF initializer and manage the tables and mappings yourself.
Disable the database initializer in the constructor like this...
public SecurityContext()
: base("DefaultConnection")
{
Database.SetInitializer<SecurityContext>(null);
}
Then you can just take the schema that EF has created thus far and manage it yourself (you can remove the migrations history table). I recommend using a SQL Server Database project so that you can source control your schema. It's now up to you to update the DbContext when the schema changes.

You can also disable it through configuration
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="DatabaseInitializerForType YourNameSpace.SecurityContext, YourLibraryName" value="Disabled" />
</appSettings>
</configuration>
