R – Fluent Nhibernate and Nhibernate 2.1.0.1003

Your version numbers aren't the same according to that exception.

... 'FluentNHibernate' uses 'NHibernate, Version=2.1.0.4000 ... which has a higher version than referenced assembly 'NHibernate, Version=2.0.1.4000 ...

2.1.0.4000 vs. 2.0.1.4000

We all missed it!

Sorry guys and thanks for all your help but I just figured.

If you pay attention to the RemoveAll() method you will see that I´m trying to delete the "q" object which is not an entity, but a IQueriable instead of passing "employee". It was lack of attention.

The right code would be:

        public void RemoveAll()
        {
            var q = from employee in _session.Linq()
                    select employee;

            var p = q.ToList();

            foreach (var employee in p)
            {
                _session.Delete(employee);
            }
        }
