Forever Free

No videos. On purpose.

This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on c# and .net you can find — even without producing a single minute of custom video.

One app that grows each day

You build a single C# application across 5 days — adding the API layer, then the database, then the UI. By Day 5 you have a complete, deployed stack.

Enterprise patterns from the start

Dependency injection, repository pattern, clean architecture — the .NET patterns that enterprise teams use from day one, not as advanced topics.

Links to Microsoft documentation

The Microsoft Learn documentation for .NET and C# is thorough and well-maintained. This course links directly to relevant pages.

Completes in 5 one-hour sessions

Each day is designed to finish in about an hour of focused reading plus hands-on coding. No live classes, no quizzes.

The 5 Days

Each day stands alone. Read them in order for the full picture, or jump straight to the day that answers the question you have today.

The best external videos on this topic.

Instead of shooting our own videos, we link to the best deep-dives already on YouTube. Watch them alongside the course. All external, all free, all from builders who ship this stuff.

Read the source.

The best way to go deeper on any topic is to read canonical open-source implementations. These repositories implement the core patterns covered in this course.
