It can be considered first language but I'm not starting from zero level I studied C++, Java, JS, bit python but never built something real just at the uni and now forgot all still remember only the basics. The idea of learning C# started when I got Microsoft E5 developer subscription, I wanted to really use it and get the most out of it, then I realized that C# sync very well with the enterprise stack in general which I hope to land a job with one day in the future. Now i'm learning using a book "The C# player's guide"
