I'm only a decade younger - I write .Net (C#) professionally - work it is Windows & Visual Studio (there is no way I'd want to mange any project that size without an IDE, tbh I much prefer using a IDE since I first got one in early 90s)

But at home - I use Jet Brains Rider (free non commercial) for C# .Net projects on Linux machines (Debian + KDE or Mint depending on machine)

I wonder if you mean Notepad++ not Notepad - I find KATE on KDE is good enough, when I just want to edit a file, but I've run Notepad++ under wine before.
