Korshub's take

A Rapid, Structured Sweep Through C#

This course compresses the C# language into 100 one-minute lessons, moving from absolute basics to genuinely advanced territory. It's built for speed and structure rather than deep-dive theory — each concept gets a focused, practical treatment with real code examples.

How It's Organized

Concepts 1-25: variables, data types, strings, loops, and methods
Concepts 26-40: object-oriented programming — classes, inheritance, interfaces
Concepts 41-55: collections and data structures
Concepts 56-70: LINQ and functional programming
Concepts 71-80: file I/O and serialization
Concepts 81-90: async/await, generics, delegates, and pattern matching
Concepts 91-100: testing, Git, NuGet, and best practices

Who It's For

Complete beginners, developers coming from another language who need a fast C# reference, or anyone who wants a comprehensive refresher without wading through a long-form course.
