No need to rush out and replace Moq, you’re fine if you’re on a lower version. We are using 4.16 or something at work, and I don’t see any need to take any action there. Didn’t have a reason to upgrade anyway.

If the SponsorLink package comes back, and kzu is determined to push forward with it (which is absolutely his right to do) then long term I guess we’ll move to something else. My preference would be to stop using mocks altogether.

A switch statement will let control fall through. A switch expression will no, and will throw an exception (and there will also be a compiler warning that it’s not exhaustive before you even run the code)
