Recently did a long overdue upgrade from 1.(something) to 2.2, and am having lots of trouble migrating my wrapper code across. One thing I'm noticing is that lots of expressions I had been using previously (via linq) are simply not supported anymore, which is very odd to me. Could you clarify whether this is by design/known/etc?

Works:
collection.Where(mydoc => !mydoc.SomeListProperty.Any())

Does not work:
collection.Where(mydoc => mydoc.SomeListProperty.Any() == false)

I will provide further info on other lambdas that are problematic, later.
