What you will learn

8 concrete outcomes

Every bullet below is something you will have built, shipped or be able to explain by the time you finish the last lesson.

  • Write modern C# with records, pattern matching, nullable reference types and file-scoped namespaces
  • Use the dotnet CLI confidently for projects, solutions, packages and test runs
  • Query and transform collections with LINQ instead of nested loops and manual bookkeeping
  • Write asynchronous code with async and await that does not deadlock or block a thread pool
  • Model a domain with classes, interfaces, generics and dependency injection
  • Test with xUnit, including fixtures, theories and assertions that fail for the right reason
  • Build a small ASP.NET Core web API with Entity Framework Core and SQLite
  • Debug effectively in Visual Studio and VS Code, from breakpoints to stack traces

Requirements

Short list, and deliberately so. If you meet these you can start today.

  • No programming experience needed; the first module starts with installing the SDK
  • Windows, macOS or Linux with the .NET 9 SDK, which the course walks you through installing
  • Around six hours a week to keep momentum across the three projects

About this course

C# rewards beginners because the tooling tells you when you are wrong before you run anything. This path uses that to its full advantage. You start in the dotnet CLI with top-level statements, add nullable reference types on day one, and let Roslyn analysers correct your habits while they are still forming rather than three projects later.

The language coverage is thorough and modern: types and records, pattern matching, collections and LINQ, interfaces and generics, exceptions, files and streams, and asynchronous code with async and await explained through actual I/O rather than sleep loops. Every module ends with an exercise that fails a unit test until your implementation is right, so progress is measurable instead of vibes-based.

Three projects give the path its spine: a console budgeting tool that reads and writes JSON, a class library with a full xUnit test suite published as a local NuGet package, and a small ASP.NET Core web API backed by SQLite and Entity Framework Core. The closing module covers Git workflow, reading stack traces, debugging in Visual Studio and VS Code, and how to structure a solution that another developer can open and understand.

Frequently asked questions

Still unsure about something? Write to misteryjj100@gmail.com and a human answers, usually the same working day.

Either works and both are demonstrated. Everything runs through the dotnet CLI first, so you are never locked into a single editor.

The fundamentals are stable, but defaults changed: nullable reference types, implicit usings and minimal hosting are on from the start. Learning those now saves unlearning older templates later.

Only indirectly. Unity uses C# but a different runtime and lifecycle, which the dedicated Unity C# scripting course covers properly.

You will have the language, testing, Git and a web API project, which is the usual junior .NET screening bar. The intermediate LINQ and async course is the natural next step.

Yuki has shipped six commercial titles, four of them solo, across PC and mobile. She teaches C# and .NET the way small studios actually use them — inside Unity, under a deadline — so the language lessons and the engine lessons arrive together. Students finish a playable game in every course, complete with menus, save files and a distributable build. She mentors at game jams most weekends and has judged three of them.
