Thanks for this, it's very timely for me: https://typescript-is-like-csharp.chrlschn.dev/

Which direction are you headed? C# -> TS? Or vice versa?

I'm curious to learn C# for a hobby project, and I know Typescript well enough so this feels like a good place to start if you use it as a reference?

It's the perfect place to start!

How do you deal with issues and feature requests? I used to put stuff on github, but nowadays I keep one off things mostly to myself. I don't want to do any support to strangers for things I have no interest in.

It makes me happy! It means people are using it :)
