EF核心按问题分组，重复的行

如何解决EF核心按问题分组，重复的行

问题在于，方法运行时，无论链接到CariHareket的表有多少行，它都会为Kontrat表创建行。

我不能分组，因为EF Core不支持（EF Core v3.1.9）

hareketService.GetAll(Predicate())//table name is CariHareket
                       .Include(s => s.Cari)
                       .Include(s => s.HedefHareketCariVirman)
                       .Include(s => s.HareketCari)
                       .Include(s => s.Kontrat).ThenInclude(s => s.KontratKalemler)
                       .Include(s => s.Kontrat).ThenInclude(s => s.KontratTarihBaglantilar)
                       .Include(s => s.Kontrat).ThenInclude(s => s.FaturaTalimativeTurkceFatura)
                       .Include(s => s.Kontrat).ThenInclude(s => s.araciCari)

CariHareket和Kontrat模型类：

public class CariHareket
{
    [Key]
    public int ID { get; set; } 
    [ForeignKey(nameof(CariID))]
    public virtual Cariler Cari { get; set; }
    public int? CariID { get; set; }
    [ForeignKey(nameof(KontratID))]
    public virtual KontratUst Kontrat { get; set; }
    public int? KontratID { get; set; }
    [ForeignKey(nameof(HareketCariID))]
    public virtual Cariler HareketCari { get; set; }
    public int? HareketCariID { get; set; }
    [ForeignKey(nameof(HedefHareketCariVirmanID))]
    public virtual Cariler HedefHareketCariVirman { get; set; }
    public int? HedefHareketCariVirmanID { get; set; }
    ...
}

public class Kontrat 
{
    ...
    [InverseProperty("Kontrat")]
    public virtual BindingList<KontratMasraflarNotlar> KontratMasraflarNotlar { get; set; }
    [InverseProperty("Kontrat")]
    public virtual BindingList<KontratKalem> KontratKalemler { get; set; }
    [InverseProperty("Kontrat")]
    public virtual BindingList<KontratTarihBaglantilar> KontratTarihBaglantilar { get; set; }
    [InverseProperty("Kontrat")]
    public virtual BindingList<KontratKasa> KontratKasa { get; set; }
    [InverseProperty("Kontrat")]
    public virtual BindingList<KontratKonteyner> KontratKonteyner { get; set; }
    [InverseProperty("Kontrat")]
    public virtual BindingList<KontratTurkceFaturaKalem> FaturaTalimativeTurkceFatura { get; set; }
}
