Top 5 Free Courses to Learn C# (C-Sharp) in 2025 - Best of Lot (original) (raw)

Many people underestimate the power of C# and never think highly of it when they talk about programming languages. Still, the truth is that C# is one of the popular programming languages of today's world, just behind JavaScript, SQL, and Java on StackOverFlow's Developer Survey for the last couple of years. There are a lot of jobs and opportunities available for experienced C# developers. It's one of the critical languages for developers working with Microsoft technologies like Windows and SQL Server. It is also one of the most popular programming languages for developing desktop GUI, surpassing Java Swing entirely in the last couple of years. I have seen many big investment banks switched from Swing to C# for their GUI development work.

C# is also very big on game development because of Unity, which is the most popular game engine in today's gaming world. If you don't know what Unity is, it's a cross-platform game engine developed by Unity Technologies and used to create video games for PC, consoles, mobile devices, and websites.

More than one-third of top games are made using Unity, and there are millions of active users of games created using the Unity engine. Unity is also used for VR, with 90% of all Samsung Gear and 53% of all Oculus Rift VR games developed using Unity.

C# is also a part of .NET, so it is used alongside languages like ASP in web development and apps, particularly on Windows 8 and 10 platforms.

Btw, If you don't mind investing money for your learning, then I also suggest you join the Unity game development using C# on Udemy.I have personally found game development is the best way to learn Programming and develop the coding sense. If you are learning a new programming language, then it just provides the best of both worlds.

You will also learn how to use Visual Studio, one of the powerful IDE for a C# developer, and the object-oriented programming paradigm.

Once you complete the course, you should have confidence in reading and writing C# code in your own applications. I highly recommend this course for anyone serious about learning C#.

4. Fundamentals of Programming: Understanding C# [Udemy Free Course]

This 10-hour long C# programming course on Udemy is again one of the best free courses on C#, which will teach you programming fundamentals like data types, OOP basics using C# like classes and objects, working with arrays, etc.
