This is a running series of C# coding challenges, one new task added every week, designed to push you into corners of the language you don't hit in everyday work and keep skills you're not currently using from going stale.
Every past challenge stays available too, along with its solution, so you can work through the full back catalog at your own pace instead of only keeping up with the newest one. With 129 lessons and counting, it's less a single fixed curriculum than an ongoing habit for staying sharp in C#.
Tim Corey is the US developer behind iamtimcorey.com and the IAmTimCorey YouTube channel — one of the most prolific independent .NET / C# educators online. He has been publishing weekly .NET content since 2017 and has anchored a generation of working .NET developers' learning path through the platform's evolution from .NET Framework to .NET Core to modern .NET.
The course catalog covers the full .NET stack: C# language fundamentals, ASP.NET Core for web development, Blazor for full-stack C# web applications, Entity Framework Core for data access, MAUI for cross-platform mobile, design patterns and SOLID principles, the testing tracks, Azure deployment, and the broader software-engineering craft topics (debugging, code review, project structure) that most pure-tutorial sources skip.
The CourseFlix listing under this source carries over 14 Tim Corey courses spanning that range. Material is paid and aimed primarily at .NET developers building real production proficiency rather than picking up syntax.
