@aaron yes it's similar I'm trying to apply the solution of:
protected override void ApplyAbpConceptsForModifiedEntity(EntityEntry entry, long? userId, EntityChangeReport changeReport) { if (entry.Entity is MyRowVersionEntity) { entry.OriginalValues["RowVersion"] = entry.CurrentValues["RowVersion"]; } base.ApplyAbpConceptsForModifiedEntity(entry, userId, changeReport); }To
protected override void ApplyAbpConceptsForDeletedEntity(EntityEntry entry, long? userId, EntityChangeReport changeReport) { base.ApplyAbpConceptsForDeletedEntity(entry, userId, changeReport); } -

Well yes the following code works if two users are editing the same entity:
protected override void ApplyAbpConceptsForModifiedEntity(EntityEntry entry, long? userId, EntityChangeReport changeReport) { if (entry.Entity is MyRowVersionEntity) { entry.OriginalValues["RowVersion"] = entry.CurrentValues["RowVersion"]; } base.ApplyAbpConceptsForModifiedEntity(entry, userId, changeReport); } -

What did you expect to happen?
