A tutorial that creates a library by incorporating real-world usage examples is great.

The lecture is good, but it's disappointing that there's no follow-up course.

There's a bit of a gap in difficulty between the beginner and intermediate courses, but it seems good for getting a feel for studying C# and grasping the basics.

It's free and great for getting to experience C#

I hesitated because it's an old lecture, but it's such a great lecture. Highly recommend, highly recommend
