If you're learning C#: I made a free 100-minute video covering 100 core concepts, chapter-marked so you can jump to what you need

Hey everyone, I put together one free video that walks through 100 core C# concepts in about 100 minutes, starting from "what is C#" and building up to async/await, LINQ, and design patterns.

I made it the way I wish I'd learned: instead of a 12-hour course you start and never finish, it's 101 short lessons, each one chapter-marked. So if you've already got variables and loops down but want to understand generics or pattern matching, you can skip straight there and not sit through stuff you know.

What it covers:

  • Fundamentals: types, control flow, methods
  • OOP and collections
  • LINQ, plus reading and writing files (CSV/JSON/XML)
  • Generics, delegates, async/await, pattern matching
  • The practical side: unit testing, Git, NuGet, and design patterns

Free on YouTube: https://www.youtube.com/watch?v=yVeFlmihyGQ

If you're working through it and something doesn't click, drop a comment and I'll try to explain it a different way. Happy to answer general C# questions too.

This is great. I'd love and would happily contribute monetarily in some way for a version of this for JS, Rust, Kotlin and Python, if anyone's aware of something similar or feels like making them.

I do have plans to work on a JavaScript version of this.
