---------------------------------
Roberto,
In your case you are using the same syntax used for a cast
from Animal item in session.Query<Lizard>() select item
you can change your query writing
(from item in session.Query<Thing>() select item).ToList<Thing>();
Diego,
I would know why in your opinion this issue is critical; I'm sure you are not talking about the query you send us because using session.Query<Animal>() you have all you need.

Diego Mijelshon commented on NH-2206:
-------------------------------------
Fabio,
In the actual code, a method has to return a IQueryable<Animal>, but the source could be Lizard or any other Animal entity depending on internal logic.
Querying Animal and filtering on the type is not possible in this case because it's using implicit polymorphism.
I consider it critical because it breaks existing code (or, more precisely, forces us to keep the old Linq provider)

Steve Strong commented on NH-2206:
----------------------------------
I agree it's an issue, but I don't think it qualifies as a priority of Major - the .ToList() does give a work around. The fact that compatibility with the old provider is broken isn't, in my opinion, a major issue. The old provider is an NHContrib project, not part of NH Core, and I don't think it's practical to ensure backwards-compatibility with it. We don't, for example, have a whole bunch of tests in the core for the old provider.
So although I'd like to see this fixed, I think there are more important areas within the new provider that could be worked on instead. Feel free to submit a patch if it's a major problem for you ;)

-------------------------------------
Steve,
I'm OK with that and you can lower the priority. I'll try to create a patch for this.
Keep in mind that, from an HQL perspective, (up)cast is a noop.

Fabio Maulo commented on NH-2206:
---------------------------------
Tests added to NHibernate.Test.Linq.WhereTests with the description: "Reported as bug NH-2206"
The issue reported by Diego is easy to fix.
The issue reported by Roberto needs something more.
