unitOfWork Remove

Hi,

I use shared unitOfWork and I need to ask you what will be with entity of Lightspeed when I launch unitOfWork.Remove() in part of code CATCH (for example in false validation)
and then in some other entity unitOfWork.Remove() and unitOfWork.SaveChanges() in part of code TRY.
Now, when I launch SaveChanges() to next entity the Lightspeed forget the previous entity. Is it true or false?

Sample:
private static void Update<B>(Context context, B newData)
where B : Entity<Guid>
{
    using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required))
    {
      try
      {
          // validation
          ValidateEntityUpdate<B>(context, newData);
          //save
          context.UnitOfWorkScope.Current.SaveChanges();
          scope.Complete();
      }
      catch
      {
          //remove
          context.UnitOfWorkScope.Current.Remove(newData);
          throw;
      }
    }
}

Hi Janis,

Calling UnitOfWork.Remove() will only mark the entity as deleted. Calling SaveChanges again will actually delete the entity from the database.

Use:

catch
{
  context.UnitOfWorkScope.Current.Remove(newData);
  context.UnitOfWorkScope.Current.SaveChanges();
  throw;
}

I hope that helps,

Hi Janis,

Sounds like you want a method unitofWork.Ignore(Entity entity) - which would unregister the entity from the unit of work? If so, this is not something which is available publicly at the current time, but we would be open to looking at this given the right reasoning :)

In what you are saying above, you want to remove the entity so your unit of work can be saved at a later point without running in to the same error? How are you currently scoping your unit of work? Is it Per Request as part of a web application or more long running?
