问题
I am new to Entity-Framework-5 and IdentityDbContext, I have managed to create my and create the AspNet membership tables,then i changed the type in one of the properties of the model, now my project wont run and its telling me that I need to run migrations. My question is, how to run migrations on the IdentityDbContext? I cant find any good guides on how to do it.
Additional information: The model backing the 'ApplicationIdentityUserDbContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).
public class ApplicationIdentityUserDbContext : IdentityDbContext<UserProfile>
{
public ApplicationIdentityUserDbContext()
: base("DefaultConnection")
{ }
}
I have attached the error when I run enable-migrations.

You do it by using the enable-migrations and add-migration command in the Package Manager Console See Code First Migrations
This will generate migration files which you can apply to the database using the update-database command (or they run automatically depending on settings).
Make sure to select the correct Default Project in the Package Manager Console, it should be the project containing your context.
