Ah, interesting! I'm using the 3.0.0 beta 2 and was under the
impression that QueryOver is the new Linq implementation.
When I use "where statuses.Contains(s.Id)" I get the exception below,
which is weird:
Test
'Lumo.Complaints.DL.Tests.ComplaintRepositoryTests.GetPotentialBreachesForUsersTest_Linq'
failed: System.Exception : Unrecognised method call:

Should I try with the Contrib Linq library, instead? I apologize for
noob questions. :)
