My recent was a month ago, but to be fair, the CTO of that company (who wrote the existing code when I joined) last wrote production code in 2008, so his code may have not been using those newer syntax features.
Yeah it's very easy to write Java style C# that is incredibly verbose and rigid, but once you understand modern c# you can see how it's this really great (imo, awesome) hybrid of functional/typed languages. They've done a ton of syntax work to let types get out of your way when you need them to, with the ability to always fallback to rigidly declaring them when you need better readability.
The downside of all this is that the only people that know how awesome C# is are people who are already doing C#. Growing the pot and trying to convince people to give it a go in its modern (post dotnet 5/"core") iteration is like pulling teeth. Everyone assumes nothing has changed since like C# 2, and given the fact it's a "boring" language that doesn't have Hacker Hype behind it, people just ignore it.
Every week you have people on HN wishing for something that does exactly what C# does but don't want to give it a shot or admit that C# is _actually_ an incredible language and toolset that does exactly what they want (and more).
