I get a compile error on this line:
System.Collections.IList instrumentList = new List<Instrument>();

instrumentList = session.CreateCriteria<Financial>("f")
                                       .CreateCriteria("fa.InstrumentList", "il", NHibernate.SqlCommand.JoinType.InnerJoin)
                                        .SetResultTransformer(new NHibernate.Transform.DistinctRootEntityResultTransformer())
                                        .List<Instrument>();

Open in new window

That gives another compile error:
The non-generic Ilist cannot be used with type arguments

IList has no relationship with IList<>, therefore you cannot convert between them. The unique common interface is IEnumerable
On the other hand, List<> implements IList, so if you can cast a collection to List<> instead of IList<>, then you can assign it to a non-generic IList.

Change line 1 to (edited):

System.Collections.Generic.IList<Instrument> instrumentList = new List<Instrument>();
