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.
