Nhibernate - Unable to query IN operation - model-view-controller

Question

Here is my requirement
I have a list of location Ids. I need to return all entities where entity.Location.Id in [list of Location Ids]
Query used
var res = from m in queryable
from id in locations
where m.Location.Id == id
select m;
queryable is IQueryable<Entity> returned from NHibernate Repository
locations is an integer list of IDs.
The above query throws an error.
"Specified method is not supported."
Any help appreciated.

The correct way of doing what you want is:
var res = from m in queryable
where locations.Contains(m.Location.Id)
select m;
