Master C# and .NET Framework - learn with code challenges, exercises, and real-life examples!

Created by: Codestars

Last updated February 2026

Our take

Based on the ratings of 1,049 students, a sample of their written reviews and the syllabus, as the course stood in February 2026. No course pays to be reviewed.

This is a beginner C# course built around the console. The syllabus shows 20 sections and about 22 hours across 133 lectures. It runs from variables, loops and methods through arrays, strings and exceptions, then into classes, inheritance, abstraction and polymorphism. There are no quizzes or coding exercises on the platform, so practice comes from challenges inside the videos. It was last updated in February 2026. About 4,850 students have joined, and it holds a 4.4 average from 1,049 reviews, with around 85 percent giving four or five stars.

Reviewers like the early sections and the mini-challenges, where students attempt a problem before the solution is shown. Tod Vachev gets credit for clear explanations, and one reader who had bounced off other C# classes said the basics-first order made the OOP ideas click. The complaints cluster late in the course. Several reviewers say the instructor speeds through screen changes and code corrections, the polymorphism section feels like it came from a different course, and interface names change between lessons. One also calls the automatic subtitles poor.

As value goes, it is a long, structured way into C# fundamentals and OOP, but not a full path to a job. Reviewers say it lacks newer C# features and has nothing on Windows forms or visual apps. People with some programming background may find parts of it skippable, and one reviewer says so about the arrays section. Beginners should expect to pause often and lean on the supplied source code in the later sections. A solid first C# course, less convincing as the only one.

Best forTotal beginners who want C# basics and OOP in one console-based course, with a challenge after each topic.
Skip it ifYou want Unity, web or desktop apps, or newer C# features, since everything here runs in the console.

Pros

  • Mini-challenges make students try a problem before the solution is walked through
  • Starts from zero and shows how to install the free Visual Studio Community Edition
  • Basics come first, so inheritance and polymorphism have a foundation by the time they arrive
  • Lectures average about 10 minutes, which suits short study sessions

Cons

  • Late sections speed up, and reviewers say screen changes and code fixes are hard to follow
  • Reviewers say it lacks newer C# features, and it stays in the console with no Windows forms
  • Late sections feel inconsistent: polymorphism changes the project and some names shift
Great explanations, examples, and also the mini-challenges, that really allowed me to make the connections by myself first before showing the best approach.
Vasco Quaresma, a student

The Beginner label fits the first half. The OOP sections move fast, and some reviewers say they needed prior grounding.

Course Description

Last year C# was named one of the most popular languages for mobile development and game development out there!


--- Why learn C#?

C# was designed by Microsoft and is a simple and modern programming language that's incredibly widely used by developers, and used by Microsoft for everything from Windows application development, to web development, and game design.

So it's a fantastically useful programming language to use, but how does taking this C# course help you? Well...

  • Are you a young developer trying to increase your skill set and make yourself attractive employers?

  • Are you an experienced coder looking to change your career path?

  • Do you know a bit of C# but really want to hone your C# skills?

  • Or perhaps you want to develop your own apps and websites?

  • Or build games?! The incredibly popular Unity game engine uses C#!

If you answered 'YES!' to any of the above, this course is exactly what you need! Take your C# coding skills from novice to pro, and get the job you want.


--- Why this course?

With over 20 hours of content, this is the biggest, best and most in-depth course yet from Instructor Tod Vachev.

As an instructor Tod has already taught over 70,000+ students to code, and has published a number of highly-rated and best-selling C# courses on Udemy... Tod takes you step-by-step through the fundamentals of C#, using regular challenges and practical exercises to make sure every student enrolled on the course is able to put theory in to practice, and use their C# skills with ease! 

Students loved his previous courses!

***** Outstanding course put together by a teacher who knows how to teach well.

***** Clear communication and beginner friendly without dumbing it down

***** The course progressively (and logically) builds concept upon concept. The lectures are short and very manageable. Excellent!


---Challenges and exercises

This is a really hands-on course! Throughout each section you'll complete in-lecture exercises and coding challenges. Experience shows that this is the best way to learn, practice and internalise the fundamentals of C#.

Each topic has a new challenge, and after you've had a go at completing the exercise/challenge by yourself, the instructor will go through every step of the exercise on screen - giving you tips an tricks as he does so! 

By the end of the course you'll have the skills and confidence to build your own projects (and more!)


--- Is this course for you?

No coding experience required, this course takes your from beginner to pro - and (other than enrolling in the course) everything you need to succeed is included in the course!


There’s no better time to become a professional developer, so enroll in the course now and you can start learning C# immediately! 

Good luck!

This is a very thorough class that gives the fundamentals of C# which gives you a solid foundation upon which to specialize in .Net and other C# niches. To do this, the instructor has all of your projects revolving around the Console. What prevents this course from getting a full 5 is the instructor will quickly click around through screens faster than I can keep up. Especially in lessons where there are niche tips and tricks being done that are never used again. Despite this, I learned more from this and have already applied it to my Unity C# development. I would recommend this course.

By Vasco Quaresma on 6/11/2020

Having had some training in C# and having consulted different books, this course helped me the most out of all the tools to get a handle of the language, especially the logic behind it and the object-oriented aspects. Great explanations, examples, and also the mini-challenges, that really allowed me to make the connections by myself first before showing the best approach. A course I definitely don't regret buying and if you feel lost as a beginner in C# and want to understand how things come together, I highly recomend it

By Theodor Nordkvist on 6/2/2020

The explanations on most topics, are clear and thorough, but on some occassions, I had trouble understanding what the instructor meant when assigning challenges. It would have helped a lot if step by step instructions for the exercises, had appeared in text boxes in the videos, or as PowerPoint slides cut into the lecture videos as screenshots. A few times, it also took me a while to figure out the pronounciation of some words, but that can be contributed to the fact that the instructor is not a native English speaker. Nothing that caused me trouble, though. Apart from this, the course is quite good, and we should be thankful to Udemy and their instructors, for offering quality courses at ridiculous prices, on as complex subjects as software development, and computer science in general, are.

By Matt Ancona on 5/11/2020

There is information missing after lesson 118. The solution changes from "IntroductionToOOP" to "CSharpOOP" and is never addressed. After this point, you cant really continue building off the Lesson side of the project, and also the Main Project gets hard to follow because new things were also added without being explained. Effectively after Lesson 118 you will have to copy the source code, and then just follow along with the rest of the videos..which is unfortunate.

I've been programming intermittently for the last 30 years, but never professionally. I've worked in IT for the last 25, mostly infrastructure, but last five years managing development teams. With the pandemic going on I had time, no income (due to the economy), and I really didn't want to waste this opportunity to come out of this event with more technical ability than I went into it. I bought this course after reading the reviews and I am most of the way through it. Said simply: I'm certain this will go down as one of the best decisions for my professional career that I have made in the last decade. The instructor is succinct and clear. His examples are easy to follow and his challenges cleanly support his lectures. He repeats important concepts multiple times, and subsequent lectures tend to build on previous ones. As an old MUD gamer I loved the text-based fantasy game project, and in fact I am building my own as a means of really learning C# and having something that I can show potential employers to demonstrate my understanding of C#. His on-screen markups have helped me fully understand the concepts (in particular the section on arrays and lists. If you are not sure this is the right course for you remember that Udemy offers a money-back guarentee so you cannot lose.

By Xavier Agullo on 2/9/2020

It's a very comprehensive course that totally fulfilled my expectations. Being "The Complete C# Course", it covers from total beginner content to some advanced topics that require a lot of practice, so depending on your initial level you might find it difficult towards the end. However, the instructor is super clear and the lectures are very well structured. All in all, this course was well spent time and money.

By Marinos Anagnostou on 10/17/2019

One of the most well explained course in C# and also one of the best. A lot of fundamental topics of the language, covered in depth with a unique simplified approach, I thing basic characteristic of the specific instructor. Not all topics of C# covered, but implemented almost all of basic foundations (not only) and a lot more. I thing it stands out and worths 100% to proceed buying this course.

By Kevin Gill on 8/1/2019

Level: Business/technology consultant. Beginner with programming languages. Reason for taking course: I needed an understanding of arrays, loops, strings, classes, methods, and .NET to be able to prototype RPA solutions with UiPath. Summary: The course was excellent. I would give 6 stars if possible. Result: With about 65% of the C# course completed, I was able to return to UiPath and break through obstacles I encountered earlier (manipulating strings, using variables and arrays, moving data and files, working with objects/methods). Observations: • Tod gets the beginner up and running from a standstill. I had never used an IDE, but quickly found myself comfortable in Visual Studio because he took the time to walk through the basics. • The course is well-constructed and very thorough. Each lesson builds a solid foundation for the next. • Tod’s teaching style is that of a trainer, not just an instructor. Repetition of previous learning allows the student to develop familiarity and speed with software, syntax, and shortcuts. Midway through course I found myself fluent enough with the language that I was setting up arrays and loops without even thinking about them. • The frequent short exercises are challenging enough to solidify the current lesson and draw out previous learning without going too far over the head of the student. • Tod stays off camera and focuses on the code, allowing the student to learn without distractions. • My only criticism is that he sometimes deletes the code that was demonstrated and reuses the variables. This can be confusing when a student is grappling with a new concept. (E.g. lesson 53-placeholders, lesson 67-lists, lesson 70-arrays.) I would suggest leaving the code intact where possible and creating new variables to demonstrate below the previous example. Luckily we can pause and rewind to work through these areas. In summary, I have to say that Tod is an excellent instructor who has developed an exceptional course that is well-paced and thorough. I highly recommend it to anybody seeking a deep understanding of C# and related concepts. Well-done Tod. This is the best online course I’ve taken to date.

By Matt Keller on 6/27/2019

Tod explained all of the concepts in a very clear, concise, and easy-to-follow manner. The flow of the course felt natural as well. Any confusion I had was very quickly cleared up by the examples and challenges that were provided. I now feel much more confident in my C# skills! While this course does not cover game design, I would still recommend it as a starting point for those interested in coding games. The course helped me to better understand concepts that will be very important for game development!

By Anne Diotalevi on 3/19/2019

The course starts out well, but then falls apart. Code is definitely changed outside of the class, without the students being told what changes were made. The instructor makes mistakes in the code, which isn't a bad thing, but then he flies through correcting them without allowing the students time to see what changes are being made. Changing screens quickly without properly pointing out which section of code you are in is another problem; by the time you look at the top of the screen to verify where he is, you have missed information. You can learn some things from the course, but it gets very frustrating after a while. To top it all off, no final version of the code is given as material; at least that would allow comparison.
