Question

My models for my blog :

namespace AlexPeta_2.Models
{
    public class Article
    {
        public int ArticleId { get; set; }
        public string Title { get; set; }
        public string Text { get; set; }
        public char Published { get; set; }
        public DateTime CreatedDate { get; set; }
        public char AllowComment { get; set; }

        public virtual ICollection<Tag> Tags { get; set; }
        public virtual ICollection<Comment> Comments { get; set; }
    }
}

namespace AlexPeta_2.Models
{
    public class Comment
    {
        public int CommentId { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }
        public string HomePage { get; set; }
        public string Comm { get; set; }
        public DateTime CreatedDate { get; set; }
    }
}

namespace AlexPeta_2.Models
{
    public class Tag
    {
        public int TagId { get; set; }
        public string TagName { get; set; }
        public virtual ICollection<Article> Articles { get; set; }
    }
}

here are my dbsets:

public class BlogContext : DbContext
{
    public DbSet<Article> Articles { get; set; }
    public DbSet<Tag> Tags { get; set; }
    public DbSet<Comment> Comments { get; set; }
}

here is my initializer :

public class BlogInitializer : DropCreateDatabaseIfModelChanges<BlogContext>
    {
        protected override void Seed(BlogContext context)
        {

            List<Tag> tags = new List<Tag>
            {
                new Tag { TagId = 1, TagName = "Javascript" },
                new Tag { TagId = 2, TagName = "Bodybuilding" },
                new Tag { TagId = 3, TagName = "Uncategorised" },
                new Tag { TagId = 4, TagName = "CSS" },
                new Tag { TagId = 5, TagName = "HTML/XHTML" },
                new Tag { TagId = 6, TagName = "APEX" },
                new Tag { TagId = 7, TagName = "PL/SQL" },
                new Tag { TagId = 8, TagName = "Personal" },
                new Tag { TagId = 9, TagName = "ASP" },
                new Tag { TagId = 10, TagName = "MVC" },
                new Tag { TagId = 11, TagName = "C#" },
                new Tag { TagId = 12, TagName = "Snowboarding" }
            };
            tags.ForEach(t => context.Tags.Add(t));
            context.SaveChanges();
        }
    }

The funny thing is : i ran the application with no Connection String in webconfig, it runs fine , i see all my tags in the controller but there is not Database file in APP_DATA ?? How come is that? or what happened?

If you do not provide a connection string, EF Code First creates the database with user credentials (windows) on the local SQLExpress instance. You can validate the same by using SQL Server Management Studio Express and logging on to the local instance.
