Hi,

Sorry for posting another issue. I just created another Class/Controller/DbSet for Offices.

public class Office {

    [Key]
    public byte Id { get; set; }

    public string Name { get; set; }

    public string City { get; set; }
}

Fetching my new endpoint with Accept: application/vnd.api+json returns NOIDCOMPUTABLE! as ids and valid numbers with Accept: application/json. I looked at the tests and it seems that byte is supported. I am not sure why the ids are not serialized properly.

Thanks!
