I try to migrate from NHibernate to EF Core. I added a repository pattern and migrate repo per repo. No I run into problems with navigation properties.

System.InvalidOperationException: The property or navigation ‘ReadJob’ cannot be added to the entity type ‘ProductRead’ because a property or navigation with the same name already exists on entity type ‘ProductRead’.

Model builder looks like this:

modelBuilder.Entity<ProductRead>(entity =>
{
    entity.Property(e => e.Id).ValueGeneratedNever();
    entity.Property(e => e.ImageUrl).IsRequired(false);

    entity.Property(e => e.AbsDeviation)
        .HasColumnName("absDeviation")
        .HasComputedColumnSql("(abs([Quantity]-[ExpectedQuantity]))", false);

    entity.Property(e => e.ImageUrl).HasMaxLength(255);

    entity.Property(e => e.NegativeDeviation)
        .HasColumnName("negativeDeviation")
        .HasComputedColumnSql("(case when [ExpectedQuantity]>[Quantity] then [Quantity]-[ExpectedQuantity] else (0) end)", false);

    entity.Property(e => e.PositiveDeviation)
        .HasColumnName("positiveDeviation")
        .HasComputedColumnSql("(case when [Quantity]>[ExpectedQuantity] then [Quantity]-[ExpectedQuantity] else (0) end)", false);

    entity.Property(e => e.Sku).HasMaxLength(36);

    entity.Property(e => e.Version)
        .IsRowVersion()
        .IsConcurrencyToken();
    
    entity.HasOne(e => e.ReadJob)
        .WithMany(e => e.ProductReads)
        .HasForeignKey(e => e.ReadJobId)
        .HasConstraintName("FK_ProductReads_ReadJobId_ReadJob_Id")
        .IsRequired(false)
        .OnDelete(DeleteBehavior.Cascade);

    entity.HasIndex(e => e.Created, "IX_ProductReads_Created_Quantity_ReadJobId_Sku")
        .HasFillFactor(90);

    entity.HasIndex(e => e.ReadJob, "IX_ProductReads_ReadJobId_CreatedSkuQuantityExpectedQuantityImageUrlNoStockTransferVersion")
        .HasFillFactor(90);

    entity.HasIndex(e => e.ReadJob, "IX_ProductReads_ReadJobId_Incl_Sku")
        .HasFillFactor(80);

    entity.HasIndex(e => new { e.ReadJob, e.Sku }, "IX_ProductReads_ReadJobId_Sku_cover")
        .HasFillFactor(80);
});

ProductRead class:

public class ProductRead : EntityBase<Guid>
{
     public ProductRead()
     {
         this.ProductEntries = new List<ProductEntry>();
     }

     public virtual Guid? ReadJobId { get; set; }
     public virtual ReadJob ReadJob { get; set; }

     public virtual DateTime Created { get; set; }

     public virtual string Sku { get; set; }

     public virtual int? Quantity { get; set; }

     public virtual int ExpectedQuantity { get; set; }

     public virtual bool NoStockTransfer { get; set; }

     public virtual int? Deviation
     {
         get
         {
             if (this.Quantity != null)
             {
                 return this.Quantity.Value - this.ExpectedQuantity;
             }

             return null;
         }
     }        

     public virtual IList<ProductEntry> ProductEntries { get; protected set; }

     public virtual string ImageUrl { get; set; }
     public virtual int? AbsDeviation { get; }
     public virtual int? PositiveDeviation { get; }
     public virtual int? NegativeDeviation { get; }
}

ReadJob class:

public class ReadJob : EntityBase<Guid> 
{
    public ReadJob()
    {
        this.ProductReads = new List<ProductRead>();
    }

    public virtual DateTime Created { get; set; }
    public virtual DateTime? Completed { get; set; }
    public virtual DateTime? Started { get; set; }
    public virtual int UserId { get; set; }
    public virtual ReadJobState State { get; set; }
    public virtual Guid? AssignmentId { get; set; }
    public virtual Assignment Assignment { get; set; }
    public virtual IList<ProductRead> ProductReads { get; set; }
    public virtual ReadType ReadType { get; set; }
}

I checked all but what am I missing?
