[Mono-dev] Linq, Nhibernate or subsonic ?

What do you mean by saying that not yet having linq to sql isn´t a big loss
and that it can be replaced by using nhibernate?
Have you tried linq to sql? have you compared it to using hibernate?
Maybe if all you code is meant to be part of some desktop application, then
you are fine with hibernate. But if you intend to build real enterprise
applications, then you should use linq to sql. Not only does it make code
more simple and easy to read, it gets things done faster than hibernate does
and you don't have to bother writing boring XML files. And it let´s you use
nameless class types while querying the data base. These nameless classes
can then be bound to a GUI control or used for further processing. Try doing
that with hibernate... you would have to perform very expensive castings 
(all your query results are strongly typed in linq to sql, but not in
hibernate... everything returned by a hibernate query is just an
'object'...) and there is absolutely no WAY to use nameless types while
querying the database with hibernate.
I've been writing java code since I was a 14 year old. I begun coding JEE at
the same time I became acquainted with the dot net framework. By the time
linq to sql was released (a couple of years later) I was very dissapointed
because I realized that the dot net framework had leaped light years ahead
of java (my personal favorite until then).
So no linq to sql support is a huge loss to me. If I were to code some
enterprise application without linq to sql support, I´d rather work on JEE
than on dot net.
