Marking object for deletion and setting reference to new object does not work

Hi

I have noticed what I find a strange behavior. When first marking an object for deletion and adding anothor object in its place. At this point, the ParentEntity and the ChildEntity are loaded and in the EntityCache:

ParentEntity.ChildEntity.EntityAspect.Delete(); // mark the child entity for deletion

var childEntity = new ChildEntity();     //create a new
ChildEntity

manager.AddEntity(childEntity);     //Add to the entityManager
          
ParentEntity.ChildEntity = childEntity;     //set the reference to the childEntity

await manager.SaveChangesAsync();//save the changes

Now I would expect the ParentEntity.ChildEntity to have a reference
to the same object as the variable childEntity, but this is not the case.
After the save, the ParentEntity.ChildEntity holds a reference to a null-entity and this entity has the EntityState Detached.

If I remove the first line ParentEntity.ChildEntity.EntityAspect.Delete();
everything works as expected, and after SaveChangesAsync, the ParentEntity.ChildEntity holds a referece to the same object as the variable childEntity and the EntityState has the state of Unchanged

Why does the behavior change because of the first line?

Best regards,
Rasmus

Hi

I do not get a duplicate key exception, as the primary key is an identity column. So after the new childEntity is added to the manager, the id is -101 and after the SaveChangesAsync, a new Id is generated for the childEntity.

So what behavior would be the correct one to expect after the save? Should the ParentEntity.ChildEntity hold a reference to a null Entity or should it hold a reference to the newly created child?

Best regards,
