What you’ll learn
Learn C# programming through real-time coding exercises designed to reinforce each topic as it’s introduced. This C# Developer course helps you understand the C# language, build object-oriented solutions, and work confidently with real-world coding patterns. You’ll gain the expertise to add value in your current role while building the skills for long-term career progression.
Getting started with C#
Begin your journey into C# by understanding how it fits within the Microsoft .NET framework. You’ll explore key concepts like the Common Language Runtime, compiling code into intermediate language, and the role of development tools. This module also covers variable declaration, data types, scope, and the difference between value and reference types. You’ll practise writing your first C# programs - building a solid understanding of the language’s syntax and structure and laying the groundwork for more advanced development.
Programming logic and flow control
Learn how to structure the logic of your applications using conditional statements and loops. You'll create programs that make decisions based on user input or data conditions using ‘if’, ‘switch’, and logical operators. You'll also work with loops (‘for’, ‘while’, and ‘do while’) to process repetitive actions efficiently. Throughout the course, you’ll build confidence in using these tools to control application behaviour, reinforcing your understanding of how program flow is designed in professional-grade C# applications.
Objects, classes and OOP principles
Understand how to design systems using classes, objects and structs, and understand key principles like encapsulation, inheritance and polymorphism. You'll explore constructors, access modifiers, properties, and static members, while covering abstract classes and interfaces – techniques that help structure clean, scalable and modular code. This knowledge is essential for working in team-based environments or developing software that can grow and adapt over time.
Working with files, events and LINQ
Take your skills further by learning how to interact with data and respond to user actions. You’ll explore file input and output streams, enabling you to read, write and manage files in C#. The course also covers delegates, events and lambda expressions – core techniques used in modern event-driven applications. Finally, you’ll get hands-on experience using Language Integrated Query to filter, sort, group and join data collections efficiently. These capabilities are highly valued in professional development settings and help bridge the gap between learning and real-world implementation.

FAQs
This C# Developer course provides hands-on training in object-oriented programming, covering key language features such as variables, methods, classes, inheritance, file handling and LINQ.
Do I need to know object-oriented programming before taking this course?
No, object-oriented programming (OOP) experience is not required. This course introduces key OOP concepts like encapsulation, inheritance and polymorphism, making them easy to understand even if you're encountering them for the first time. You’ll practise applying these principles in real code, building your confidence in how to design reusable and maintainable systems. If you’re completely new to programming, you might consider starting with our Introduction to Programming course before enrolling in C# Developer.
How is C# used in practice?
C# is a versatile language used extensively in enterprise environments for building desktop software, web services and cloud-based solutions, particularly on Microsoft platforms. It's also popular in game development via the Unity engine, and is widely used in financial services, healthcare, and government systems. C# integrates smoothly with databases, making it valuable in data-heavy applications.
What are the next steps after completing this course?
After completing the C# Developer course, you will receive a certificate confirming your attendance. Many learners then move on to ASP.NET Core training to develop web-based applications using the C# skills acquired. This progression allows you to understand how to build modern, scalable web services and applications. You may also consider courses in SQL (Oracle) or Microsoft Database to strengthen your data handling capabilities.
