Hi,
When we use child entity with ISoftDelete, we got an exception on deletion function of repository. But, when we remove implementation of ISoftDelete interface, then we completed deletion successfully. Could you solve about this problem? Because, we have previously opened different questions on this problem. I'am sharing with our question link at the bottom.

Hi ElifKaya,
Can you please confirm whether you are implementing ISoftDelete for your parent entity also, in your case for Model entity ?
Thank you, Anjali

Hi,
Actually, I added ISoftDelete interface in only child entities. Do we have to use it in both parent and child tables? We used only hard deletion in a parent entity.
Now I added it to the parent entity as well and it worked.
Thanks

Hi ElifKaya,
As you are trying to hard delete the parent it is throwing error, since the child entities have the parent entity reference (ModelId). By implementing ISoftDelete it is setting IsDeleted to "true", so the reference will exist. So either you can set soft delete for both parent and child entities, or set hard deletion for both.
Also you can try cascade try: .OnDelete(DeleteBehavior.Cascade)

please do let me know if this helps you
Thank you, Anjali
