Question

I’m trying order a Linq to NHibernate query.

                var clients = (from c in session.QueryOver<Clients>()
                 orderby c.Nom
                 select c
                ).List();

It doesn’t work : List() isn’t an existing method.
It works if I write that :

            var clients2 = (from c in session.QueryOver<Clients>()
             orderby c.Nom
             select c
            );
            var clients3 = clients2.Asc.List();

There is a difference if orderby is used or not.
In the previous code, the clients2 type is NHibernate.Criterion.Lambda.IQueryOverOrderBuilder.

            var clients4 = (from c in session.QueryOver<Clients>()
             select c
            );

In this case clients4’s type is NHibernate.Criterion.QueryOver.
Does someone know this issue ?

QueryOver is not the LINQ API. You should use the Query extension method instead.

var clients = (from c in session.Query<Clients>()
                orderby c.Nom
                select c
               ).List();

Update

using NHibernate.Linq;
