Debug code-first Entity Framework migration codes

Question

I\'m using Entity Framework code first in my website and I\'m just wondering if there is any way to debug the migration codes. You know, like setting breakpoints and stuff l

My answer might be a bit silly but anyway here it goes. If you, like me, some times have problems in the Seed() method what I usually do is simply create a public method that calls the Protect Seed().

public void SeedDebug(AppDbContext context)
{
    Seed(context);
}

then in my HomeController I call this method in Debug mode.

public class HomeController : Controller
{
    var appDb = new AppDbContext();
    public ActionResult Index()
    {
        var config = new Configuration();
        config.SeedDebug(appDb);
        return View();
    }
}

I know it's a bit lame solution, but it's simple and quick. Of course this has to be done after the model been created. So step by step:

1. comment the seed method and execute the update-database to create the model

2. uncomment the method Seed() and plugin the "hack" I mentioned above.

3. in the configuration disable Auto migrations

   AutomaticMigrationsEnabled = false;//if you have this disabled already skip this step

4. Debug your application, fix the error and remove the "hack"
