I have updated the tests to reflect the update I'm trying to do using the Linq/Table API:
unfortunately they fail even earlier - at the schema generation.
On further inspection, the deprecated attributes are the only attributes the Linq API seems to respect, which is a bigger issue, however I'm not using the attributes in my code. If there's another way I could create a failing test for enums please let me know.
It is indeed an issue, I included it for next release.
