Re: JIRA

Interesting about the performance, but let me toss in a few comments
regarding perceptions... If we want to drive wider adoption of NH,
LINQ-to-NHibernate has to be in NH.Core. There is a lot of interest in
LINQ-to-NHibernate as Microsoft is pushing LINQ really hard. I understand
your concerns with the current implementation, Fabio. I don't understand why
we can't use the current implementation and swap it out later when
ExprTree->SQL is working.

Imagine if we took a hard line with NH Generics. They're not as performant.
They can't go in Core. If you want to use generics, then download this extra
package (NH.Contrib). We would have made adoption that much harder for the
average developer. Same holds true of LINQ-to-NHibernate IMHO. If it isn't
in NH.Core, fewer people will use it and (I suspect) many developers and
managers will discount NH because it doesn't have "native" LINQ support like
the Microsoft products.
