Better: add the initializer to the static constructor, like this:

public class MyDbContext : DbContext 
{
    static MyDbContext()
    {
        Database.SetInitializer(new MyDbContextContextInitializer());
    }
}

Answer 2

You can create the tables yourself - the easiest way is:

IObjectContextAdapter adapter = (IObjectContextAdapter)context;
string script = adapter.ObjectContext.CreateDatabaseScript();
context.Database.ExecuteSqlCommand(script);

Where context is my EF 4.1 database context. Prior to this code I drop all the tables (from the last time I created the db), and after this I seed it with data.

You need to add this to your Application_Start()

 Database.SetInitializer(new MyDbContextContextInitializer());
 var context = new MyDbContextContext();
 context.Database.Initialize(true);

The last line forces the DB to created

To set the auto drop and create you would do something like this...

public class MyDbContext : DbContext 
{
    public IDbSet<Foo> Foos { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        Database.SetInitializer(new MyDbContextInitializer());

        base.OnModelCreating(modelBuilder);
    }
}

public class MyDbContextInitializer : DropCreateDatabaseIfModelChanges<MyDbContext>
{
    protected override void Seed(MyDbContext dbContext)
    {
        // seed data

        base.Seed(dbContext);
    }
}
