Debug.Fail was called
I just upgraded to LinqPad 7 and am receiving this error when executing a simple LINQ query only when a where clause is included:

.Where works fine. These are causing the error:
where cs.DisplayName.Contains("Rental") == false
where ut == null
These worked fine in the previous version.
Thanks
Chris

Can you post the entire query and the backing schema?
Never mind - I've found the likely cause and will release a beta to fix this soon.
Try the 7.2.1 beta and let me know how you get on:

Thanks Joe. The beta fixed the problem.
