Question

OK. I have turned off AutoDetectChangesEnabled, and when I query the context, modify an entity and attempt to save changes, nothing gets updated. I would expect that.

But when I mark the entity as modified, I would expect it to change.

Any ideas?

I am using the UnitOfWork, Repository, Service pattern.

If I enable AutoDetectChangesEnabled then all is fine.

What is the standard way to persist changes to attached objects?

What about detached objects?

Thanks in advance,
Sam

It’s not just entities what is tracked, but relations as well.

ObjectContext.ObjectStateManager
      .ChangeRelationshipState(resolution, resolution.Message, r => r.Message, EntityState.Added);
