Parameter count mismatch

I'm getting a parameter count mismatch exception when running a LINQ query using Lightspeed 3. 

The problem seems to be related to using an || in my where clause, ie

where
    i.Id == itemId &&
    (i.abc == abc || i.xyz == xyz) &&
    i.somethingElse == somethingElse

The stack trace is:

   at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks)
   at System.Delegate.DynamicInvokeImpl(Object[] args)

Is this a bug, or should I be writing my LINQ query differently?

It's probably a bug, but it looks like it's related to some other stuff that's going on in your query.  I'm guessing you're doing a join or have multiple from clauses, plus possibly a projection in your select clause.  Could you post the full query please?  Thanks!

I don't have the full query at hand, but it did include two joins and a projection, like this:

var stuff =

from i in UnitOfWork.Items

join m in UnitOfWork.Members where i.MemberId equals m.Id

join h in UnitOfWork.ItemHistory where h.ItemId equals i.Id

where m.Id == memberId &&

(i.Id == itemId || i.ParentId == itemId) &&

i.IsDeleted == false

select new { Name = i.Name, ItemId = i.Id, LastUpdated = h.UpdatedDate }

Aha, thanks -- reproduced and investigating.

A fix for this will be included in the next drop.  Thanks for letting us know about the problem.

Great - thanks for fixing it so quickly.  When's the next drop planned for?

It should be in the store now.
