Upon inserting entities return the newly seeded values for primary keys about detached-mapper HOT 3 CLOSED

Hi @traiannemes,
Ok, first thing would be checking that you are using the return value of MapAsync and not the entity that you passed as a parameter (they are not the same!).
MapAsync takes a DTO that may or may not be of type TEntity, loads a TEntity from the DB using the key of the given parameter and copies the matching properties recursively.
At the end it returns the instance of TEntity that was loaded from the DB by EF using a regular query and that should include all EF configs and magics.
Secondly, I let EF to handle as much as possible, the modify state, so maybe a call to ChangeTracked.DetectChanges may be needed for some value to be calculated (?) I'm not sure about this...
I'd really appreciate if you attach a piece of code to have more context on this.

Thank you Leonardo for the clarification, I assume next time I should pay more attention to your wiki pages :) I will close this ticket and thank you again for the explanation.

Glad it worked!
