Learn C# to ship a real app in four months
Four months at an hour a day — about 110 hours on Microsoft's free learning path, one beloved book, and a real project — takes a beginner to writing C# they understand. C# is a clean, modern language with first-class free tooling, which makes it one of the gentler serious languages to start with. You will not be a .NET expert. You will be able to build a working application by yourself.

1.Microsoft Learn — C# learning path
Microsoft's official C# learning path is free, browser-based, and unusually good. You write and run code in-page from the first module, so there's nothing to install to begin. Start with "Get started with C#, Part 1" and work through the connected paths in order — syntax, data types, methods, branching, loops, debugging. Don't passively read: do every interactive exercise and the practice challenges. This gives you the modern, current dialect of C# straight from the people who make it.

Microsoft Learn C# path →2.The C# Player's Guide, 5th edition
RB Whitaker's book treats learning C# like leveling up in a game, with over 100 hands-on challenges, and it is the most loved beginner C# book for good reason. The current 5th edition is updated for C# 10, .NET 6, and Visual Studio 2022 — a 6th edition is in slow early access, so the 5th is still what to buy. Read it alongside the Microsoft path: the path drills the syntax, the book builds the deeper understanding and gives you problems worth chewing on.
About $30 paperback or ebook (Amazon or the author's store)
The C# Player's Guide →3.Build a real project
Pick one and finish it. For general programming: a console app with real structure — a budget tracker, a task manager backed by SQLite, a small text-based game. For games: a tiny but complete 2D game in Unity, which is built on C# and free for individuals. Use Visual Studio Community or VS Code, both free. Structuring classes, handling input and errors, and shipping something that runs are the skills no tutorial gives you. This is where C# stops being lessons and becomes a tool you own.
Free (Visual Studio Community, .NET SDK, Unity Personal)
.NET C# resources (tooling) →If this doesn't fit you
If your only reason for learning C# is to make games, lean harder toward Unity from the start: do the Microsoft path for raw syntax, skip ahead to Unity's own free "Create with Code" course, and make the game your project. The general path teaches you to program; Create with Code teaches you C# in the specific shape Unity expects, which is what you'll actually write.
Why this path
C# beginners stumble in two places: they get lost installing and configuring tooling before writing a line, and they confuse the language with the sprawling .NET ecosystem around it. This path sidesteps both. Microsoft Learn runs in the browser so you start coding immediately, the Player's Guide turns practice into something you actually want to do, and the project forces you to assemble a whole working program. Skip the project and you'll have done a hundred exercises without ever having built a thing — which is the only part that proves you learned it.
