I wanted to try DO4 (4.2.0). My DB is SQL Server 2008. UpgradeMode="Recreate" I had 2 classes based on Entity and 5 DB tables

And ALL my tables were deleted! I saw only 3 service tables Metadata.Assembly, Metadata.Extension, Metadata.Type

Cool and unique feature.

fortunately, it was test DB.

As you know programmers a very lazy by nature.

I didnt expect these dangerous modifications from simple ORM.

I had 2 classes mapped on tables, but these tables were deleted too. :D

Now I set upgradeMode="Recreate" I have 2 classes

namespace BookShopData.DomainModel
{
    [HierarchyRoot]
    [TableMapping("Users")]
    public class User : Entity
    {

        [Field, Key]
        public int UserID { get; set; }

        [Field]
        public string Login { get; set; }

        [Field]
        public string Surname { get; set; }
     }

  [HierarchyRoot]
    [TableMapping("Books")]
    public class Book : Entity
    {
        [Field, Key]
        public int BookID { get; set; }

        [Field]
        public string Title { get; set; }

        [Field]
        public int Cost { get; set; }
   }
}

Whe I try to run my application I receive 'Type 'BookShopData.DomainModel.Book' is not found in model.'
