Using N-Tier Entity Framework, how can I access an entity that has been marked as deleted?

Question

Note: My project is using N-Tier Entity Framework (https://ntieref.codeplex.com/), which is different than regular Entity Framework.

On the Client side, when I attempt to access an entity that has been marked as deleted, it does not show up in my foreach loop.

foreach (var entity in DataContext.EntitySet.Where(x => x.ChangeTracker.State == ObjectState.Deleted))

I can’t access an entity that is marked as deleted.

var entity = DataContext.EntitySet.Where(x => x.ChangeTracker.State == ObjectState.Deleted).FirstOrDefault();

@ChristofSenn How do I access the entity marked as deleted when I’m in the Client, before saving changes?

Entities marked as deleted are hidden and don't get returned when enumerating the entity set. To get all entities (i.e. including deleted) you can use the following method:

Interface:

IEntitySet<TEntity>.GetAllEntities();

Sample:

foreach (var entity in DataContext.EntitySet
                             .GetAllEntities()
                             .Where(x => x.ChangeTracker.State == ObjectState.Deleted))
