Learn C# and .NET for Free with freeCodeCamp: A Student's Guide

What this guide is about

freeCodeCamp is one of the most loved free learning sites on the whole internet. It is run by a charity, not a company chasing money. That means you never pay. There is no credit card. There is no "free trial" that secretly charges you later. It is just free.

For C# and .NET, freeCodeCamp gives you three big things. First, very long YouTube courses that can run for many hours. Second, a huge pile of written articles that explain one idea at a time. Third, a real certification you earn with Microsoft.

The problem is that "many hours of free video" can feel scary. Where do you start? How do you stay focused on a video that is eight hours long? This guide answers all of that. It gives you a plan, some focus tricks, and small code examples so you know what you are walking into.

A real-life analogy first

Think about learning to swim at a public pool.

The pool is free to enter. Nobody charges you at the door. But the pool is big, and the deep end looks scary. If you jump straight into the deep end, you panic.

So you do not do that. You start in the shallow end. You learn to float. Then you learn one stroke. You practise in short bursts, then you rest. Bit by bit, you move toward the deep end, and one day it feels easy.

freeCodeCamp is exactly like that free pool. The water (the courses) is free and open to everyone. But an eight-hour video is the deep end. You do not swim it all in one go. You start shallow, swim in short bursts, rest, and come back. That is the whole trick.

The three ways to learn here

Let's break down what freeCodeCamp actually offers for C# and .NET. There are three doors, and each one suits a different mood.

You do not have to pick just one. The best learners mix all three. Watch a video to see the big picture. Read an article to nail one tricky idea. Earn the certificate to prove you did the work.

Door 1: The long YouTube courses

freeCodeCamp's YouTube channel has full courses, not just clips. For C#, there are a few famous ones.

There is a beginner course called "Learn C# - Full Course with Mini-Projects." It runs about eight hours. It starts from zero and builds small projects as you go, which is great because you build things instead of just watching.

There is also an "Advanced C# Concepts" course that runs around 15 hours. This one is not for day one. It digs into harder topics like delegates and events. Save it for when you already know the basics.

These courses are long on purpose. They are like a full book read out loud, with a teacher typing code in front of you. The big win is that you can pause, rewind, and copy what they type. The big risk is that you watch for hours and remember nothing because you never typed anything yourself.

So here is the golden rule for long videos: type along. Do not just watch. When the teacher writes a for loop, you write it too.

// A simple program you might type along to in the beginner course.
// It says hello, then counts to five.
 
Console.WriteLine("Hello! Let's count.");
 
for (int i = 1; i <= 5; i++)
{
    Console.WriteLine($"Number {i}");
}

When you run that, you see five lines of counting. Small wins like this keep you going.

A good order to watch in

Here is a simple plan. Follow it from top to bottom. Do not skip ahead, even if a later topic looks cool.

The idea is to never sit and watch for hours with no action. Watch a bit, type a bit, build a bit. That loop is what makes learning stick.

Door 2: The written articles

The link at the top of this page goes to the freeCodeCamp C# article tag. This is a goldmine. Each article covers one topic and explains it clearly.

Articles are perfect when a video confused you. Say the video rushed past "what is a class." You can find an article that spends a whole page on just classes, with examples you can read at your own speed.

Reading also lets you copy code without pausing a video every five seconds. Here is the kind of small example an article might show you when teaching about classes.

// A class is like a blueprint. This one describes a Dog.
public class Dog
{
    public string Name { get; set; }
    public int Age { get; set; }
 
    public void Bark()
    {
        Console.WriteLine($"{Name} says: Woof!");
    }
}
 
// Now we use the blueprint to make a real dog.
var rex = new Dog { Name = "Rex", Age = 3 };
rex.Bark(); // prints: Rex says: Woof!

Notice how the article-style code is small and focused. That is on purpose. You can read it, copy it, run it, and change it in two minutes. Try changing the name and age yourself. That tiny change teaches you more than re-reading would.

Door 3: The free C# certification

This is the big one. freeCodeCamp teamed up with Microsoft to make the Foundational C# Certification. It is free and open to anyone in the world.

Here is how it works. You complete a 35-hour training course. The course is split into 7 smaller courses. Each one has 6 to 8 short lessons. You cover the real basics: your first console app, logic, data types, variables, methods, and even debugging.

The best part is that the early lessons run right in your browser. You write C# without installing anything. That removes the most common reason beginners quit, which is getting stuck on setup.

After the training, you take an exam. It has 80 questions and is hosted on freeCodeCamp. Pass it, and you get a certificate you can share with schools or employers.

There are also free video walkthroughs on the freeCodeCamp YouTube channel where C# experts go through the training. If a lesson confuses you, the walkthrough is like having a teacher sit next to you.

How the pieces fit together

It can feel like a lot of separate things. A diagram helps. Here is how the courses, articles, and certificate all connect.

Everything points toward the same goal: you writing real C# with confidence, and having proof of it.

Tips to stay focused on long videos

Long videos are the hardest part. An eight-hour video can break your brain if you try to watch it all at once. Here are tricks that really work.

Watch in 30-minute pieces. Set a timer. Watch for half an hour, then stop. Your brain needs breaks to save what it learned.

Always type along. This is the most important tip. Reading or watching feels like learning, but it is not. Typing is. When the teacher writes code, pause and write it yourself first.

Take "ugly notes." Keep a text file open. When you learn something, write it in your own words. It can be messy. The act of writing helps you remember.

Use a checklist. Long videos have chapters in the description. Tick each chapter off as you finish it. Seeing progress keeps you motivated.

Speed it up a little. Many learners watch at 1.25x speed. It keeps your mind awake. But slow back down for the hard parts.

Rebuild it from memory. After a chapter, close the video. Try to write that code without looking. If you get stuck, that is the exact thing you need to review.

Here is a small example you can use as a "from memory" test. After learning about methods, can you write one like this without peeking?

// A method takes input, does a job, and gives an answer back.
// This one adds two numbers.
int Add(int a, int b)
{
    return a + b;
}
 
int total = Add(7, 5);
Console.WriteLine($"The total is {total}"); // The total is 12

If you can write that on your own, you understood methods. If not, rewatch that part. Simple test, very honest.

Who this suits best

freeCodeCamp fits some people perfectly.

Students love it because it costs nothing. You can learn real C# without asking your parents for money. The certificate also looks good on a first job application.

Self-taught learners love it because it is structured. The certification gives you a clear path with a start and an end. You are not just guessing what to learn next.

People switching careers like it because they can learn at night and on weekends, in small pieces, for free. No risk.

It is less ideal if you want hand-held help from a live teacher who answers your questions in real time. freeCodeCamp has a friendly forum, but it is not a live classroom. Still, for free self-study, it is one of the best on Earth.

A note on modern .NET and C#

The courses teach C# basics, and those basics almost never change. A for loop today works the same as a for loop five years ago. So old course videos are still useful.

But the wider .NET world does move forward. Right now, .NET 10 is the LTS release. LTS means "long-term support," so it gets fixes for years. It is a safe, stable choice for new learners.

The language keeps growing too. C# 14 has already shipped. And a fun feature called union types (C# 15) is in preview in .NET 11. You do not need any of this on day one. Master the basics first. Just know the language is alive and getting better.

One more grown-up tip for later. Some popular .NET tools, like MediatR, MassTransit, and AutoMapper, now need a paid commercial license in many cases. You will not touch these as a beginner. But when you reach bigger projects, check a tool's license before you depend on it. It is a good habit.

A simple weekly plan

If you like a schedule, here is a gentle one. It assumes a few hours a week. Stretch it out if you are busy. There is no rush.

Six weeks is just a guide. Some weeks you will do more, some less. The only rule that matters is to keep showing up.
