Csharp 一对多：从某处插入时出现带有 EF core 的未知列

我有简单的一对多关系.

public partial class LinkedDocument
{
    public Guid Id { get; set; }
    public Guid DocumentId { get; set; }

    public virtual TblDocumentData Document { get; set; }
}

public partial class TblDocumentData : IEntity<Guid>
{
    public Guid Id { get; set; }
    // other props
    public virtual ICollection<LinkedDocument> LinkedDocuments { get; set; } = new HashSet<LinkedDocument>();
}

modelBuilder.Entity<LinkedDocument>(
        entity =>
        {
            entity.ToTable("LinkedDocument");

            entity.HasKey(e => new {e.Id, e.DocumentId})
                  .HasName("PK_LinkedDocument")
                  .IsClustered(false);

            entity.Property(e => e.Id).ValueGeneratedNever();

            entity.HasOne(d => d.Document)
                  .WithMany()
                  .HasForeignKey(d => d.DocumentId)
                  .HasConstraintName("FK_LinkedDocument_TBL_DocumentData_DocumentId")
                  .IsRequired()
                  .OnDelete(DeleteBehavior.Cascade);
        });

和Tbl_DocumentData Fluent API(仅部分)

entity.HasMany(d => d.LinkedDocuments)
                      .WithOne(d => d.Document)
                      .HasForeignKey(d => d.DocumentId)
                      .IsRequired();

在保存时，我有如下代码:

this._ctx.Set<TblDocumentData>().Add(documentData);
this._ctx.Set<LinkedDocument>().Add(new LinkedDocument {Id = attachmentModel.EntityId, DocumentId = documentData.Id});
await this._ctx.SaveAsync(cancellationToken);

但在保存时，我看到错误:列名‘TblDocumentDataId’无效. 在调试控制台中，我可以看到SQL脚本是这样生成的:

INSERT INTO [LinkedDocument] ([DocumentId], [Id], [TblDocumentDataId])
      VALUES (@p22, @p23, @p24);

按解决方案搜索-找不到第TblDocumentDataId列-因此这是EF添加的内容.

我在一对多关系的配置中遗漏了什么？
