Hello ryasn：）

EF （Code-First）won't create db or related DataTables until you begin to use it——I mean you should：

1）just do inserting data contents into the entity models，such as：

using (EFContextInstance efi = new EFContextInstance())
{
   efi.EntityModel.Add(your instance);
}

2）Just make a new class that inherit from DropDownDataBaseIfModelChanges class，and override Seed function to do something initailization（Sample from：http://thedatafarm.com/blog/data-access/seeding-a-database-with-ef4-code-first/）。

Reguards！
