با سلام 

من پروژه حدیدی رو شروع کردم که در این پروژه از mvc5 استفاده می کنم و در کد خودم در seed کد هایی رو نوشتم و دیتابیس خودم رو روی حالت گذاشتم که اگر مدل تغییر کرد دیتابیس تغسسر کنه اما قسمت seed اصلا اجرا نمیشه حتی زمانی که پروژه رو برای بار اول اجرا میکنم مرورگرم بعد از حتی 20 دقیقه باز هیچی نشون نمیده تا اینکه برنامه رو stop کنم و دوباره اجرا بگیرم

public class ApplicationDbInitializer : DropCreateDatabaseIfModelChanges<ApplicationDbContext> 
    {
        protected override void Seed(ApplicationDbContext context) {
            InitializeIdentityForEF(context);

            var positions = new List<Setting>{
                     new Setting { Position = "TopA", Limit = 0, Source = 0, Type = "ASC", Charecters = 0},
                     new Setting { Position = "TopB",Limit = 0, Source = 0, Type = "ASC", Charecters = 0},
                     new Setting { Position = "TopC",Limit = 0, Source = 0, Type = "ASC", Charecters = 0},

            positions.ForEach(x => context.Settings.Add(x));
