Example:
Expected: "Oh, you're on Linux? I heard about Rider. We use Windows and Visual Studio here for parity. You're okay with that, right?" (me: Obviously, tools are tools)
Actual: "Does .NET run on Linux? What is Rider?"
I mean, .NET has been running on Linux since forever now (11 years according to https://news.ycombinator.com/item?id=9459513, let's say about 9 for stability because I feel generous). How do they not know about it?
