What is it

C# is a modern, object-oriented language developed by Microsoft, running on the .NET platform — undergraduate study covers its similarities to Java, along with distinctive features like properties, LINQ, and async/await for asynchronous programming.

Why it matters

C# is the primary language for the Unity game engine and much of the Windows and enterprise .NET ecosystem, making it a genuinely practical skill for students interested in game development or enterprise software careers.

Exam tip

Learn LINQ (Language Integrated Query) early — it lets you write data filtering, sorting and transformation code far more concisely than manual loops, and fluency with it is often what distinguishes idiomatic C# code from code that merely works.
