Free C# Learning Resources

A buddy and I have created a vision for a text based browser MMO that will work on all platforms, (IOS, Android, PC) and we have decided we are going to use C# as our language. However I only have a very small amount of experience in coding and he has none, I have been watching and following along to tutorials on YouTube and that seems to be somewhat helpful, however any in depth learning site seems to be behind a paywall. The individual programmer I do know told me to get the basics down and just start working on projects and learn as from there, which seems to be an answer you see thrown around a lot, however I like to learn both ways and I was ultimately curious if anyone knows of any free learning resources or has any tips to give when learning a programming language or C# specifically.

I would say dump c# and use java, if you want pure open source freedom multi platform. What makes it the best is the software IntelliJ, it beats visual studio, and vs code completely. Programming with Java is a joy. It has a lot less headaches than c# I feel, and I been using java for 2 months, and c# for about 4-5 months before that.
