EF6 Beta1 - db.Database.CreateIfNotExists(); 启用迁移后不再创建数据库

Question

db.Database.CreateIfNotExists(); 不再创建数据库,并在启用迁移后始终返回true.我也没有在发布节点中看到任何关于它的内容.这是虫子吗？

请注意,在nuget控制台中执行"Enable-Migrations"后,AutomaticMigrationsEnabled = true或false都不起作用.

public void TestMethod1() {
        //using (var db = new Hive.Models.HiveDbContext()) {
        using (var db = new TestDbContext()) {
            var returnValue = db.Database.CreateIfNotExists();

            Console.WriteLine(returnValue);
        }
    }

public class TestDbContext : DbContext {

}

internal sealed class Configuration : DbMigrationsConfiguration<UnitTestProject1.TestDbContext>
{
    public Configuration()
    {
        AutomaticMigrationsEnabled = true;
    }

    protected override void Seed(UnitTestProject1.TestDbContext context)
    {
        //  This method will be called after migrating to the latest version.

        //  You can use the DbSet<T>.AddOrUpdate() helper extension method 
        //  to avoid creating duplicate seed data. E.g.
        //
        //    context.People.AddOrUpdate(
        //      p => p.FullName,
        //      new Person { FullName = "Andrew Peters" },
        //      new Person { FullName = "Brice Lambson" },
        //      new Person { FullName = "Rowan Miller" }
        //    );
        //
    }
}
