Answer 1

您正在尝试覆盖未在基类中定义的属性（NewGenerator）。

只需删除override关键字：

即可

public bool NewGenerator {
    get {
        return true;
    }
    set {
        // Do nothing
    }
}

Answer 2

 public class CADExpertInitalizeDB : DropCreateDatabaseIfModelChanges <CADExpertContext>
    {
        protected  override void Seed(CADExpertContext context)
        {
            context.CADExperts.Add(new CADExpert { Id = 1, Name = "Rice", inStock = true, Price = 30 });
            context.CADExperts.Add(new CADExpert { Id = 2, Name = "Sugar", inStock = false, Price = 40 });
            context.SaveChanges();
            base.Seed(context);
        }
    }
