Set onupdate foreignkey EF core

Question

See more:

Is there an option to set OnUpdate to Cascade of ForeignKey using Fluent API? There is only for OnDelete behavior.

What I have tried:

modelBuilder.Entity<Entiteti.NabavkeDetails>()
       .HasOne<Entiteti.Nabavke>()
       .WithMany()
       .OnDelete(DeleteBehavior.Cascade);

Currently, EF doesn't allow you to modify the primary key of an entity, so cascading updates don't make much sense. You will have to manually edit your migration to enable them, as described in this SO post[^].

There's a suggestion that this could change in a future version of EF Core:

c# - Is it possible to configure EF core "ON UPDATE" behaviour for foreign keys? - Stack Overflow[^]:
It's not possible from the Fluent API today.

...

When mutable keys are enabled (issue #4073[^]) there will likely be Fluent API introduced to let you configure the ON UPDATE behavior.
