Thank you for reply. We have a lot of usages of such kind so we'll be waiting for fix, but anyway thanks for advise.
This is a show-stopper for my company's use of the library - we upgraded to 3.3.1 today and very quickly reverted back to 3.2.1 due to this issue.
Thanks for letting us know , we will prioritize it accordingly.
I think I have a fix for this here: https://github.com/datastax/csharp-driver/pull/315
Merged!
Thanks .
FYI: We plan to simplify the ExpressionVisitor once is done.
