Where do I go once I have the basic knowledge of a programming language?

Question

I think I now have the basic tools to be able to write programs. What I'm currently doing at work has nothing to do with programming so I'm looking for a platform that has problems for me to solve as practice, I want to start with C# 1st

Answer 1

research c# on the web

Answer 2

try to find a way to implement prohramming with your work.
I did that and it saved me from a lot of repetitive tasks allowing me more free time.
At the same time I had to face and solve real problems that go beyond "helloworld" and the overall experience was very satisfying and educational.
