Requirements

Basic knowledge of C# and .NET (any version) — if you’ve built a simple API or console app, you’re good to go!

Familiarity with Visual Studio or VS Code (enough to run a project and write/debug code)

A working installation of .NET 9 SDK and your favorite IDE (don’t worry, we’ll walk you through setup!)

Some experience with Entity Framework and ASP.NET Core is helpful, but not required — we keep things beginner-friendly.

No advanced architecture skills, no previous .NET 9 experience, and no fancy hardware needed. This course is designed to be simple, funny, and practical — even if English isn’t your first language.
