When I was learning c#, I found the .Net framework tutorials available on freecodecamp to be good.
Also, using the Jetbrains Rider IDE (assuming this is for private non-commercial purposes, as per the terms of their free license) rather than VSCode or Visual Studio. VSCode is still lacking in features when it comes to c#, and Visual Studio probably makes more sense if you're already accustomed to c# dev.
I really thought it had dwindled for good after the failure of the original run of Steam Machines, feels great to be where we're at now
