CSVDataLoader not populating base class (TPH)

[maganuk]

Hi,

One of my entities is using the Table per Hierarchy model as follows:

[Table("Books")]
public class Book
{
    public int ID { get; set; }
}

public class Magazine : Book
{
    public string Title { get; set; }
}

public class Novel : Book
{
    public string ISBN { get; set; }
}

My CSV file is titled Books.csv and has ID, Title, ISBN, Discriminator

Everything else in the database (which is not TPH) is getting loaded perfectly fine, but the DbSet of Books, Magazines and Novels is always empty. It works fine if I manually add an entity using the context and do save changes.

Could you please point me in the right direction?

Thanks
Best Regards

Vishal
