IT Certification Overview

This course provides a solid foundation in C# programming, equipping learners with the essential skills to write robust, maintainable code for the .NET Framework and .NET Core. With no prior object-oriented programming knowledge required, participants will progress from basic procedural syntax to key object-oriented concepts such as classes, constructors, and properties. The course focuses on the C# language itself—covering console applications, class libraries, and an introduction to unit testing—preparing learners to build on their skills in more advanced C# development. Through a blend of lectures, demonstrations, and hands-on exercises, learners will gain the confidence to create efficient and reliable C# applications.

What Our Happy Alumni Say About Us

Prerequisites

Learners should have:

  • Some prior exposure to basic programming concepts (equivalent to QA’s Programming Foundations course)
  • Basic familiarity with using an IDE or code editor (helpful but not essential)

Target audience

This course is designed for:

  • New C# developers looking to build core programming skills
  • Developers transitioning to .NET from another language
  • Individuals seeking a strong grounding before advancing to C# Intermediate

Learning Objectives

By the end of this course, learners will be able to:

  • Write C# code using sequence, selection, and iteration constructs
  • Declare and manage variables, data types, and operators effectively
  • Create and use classes and structures, including fields, properties, and methods
  • Apply access modifiers (private, internal, protected, public) appropriately
  • Implement generic types and work with collection classes such as List<T> and Dictionary<K,V>
  • Use lambda expressions to simplify and streamline code
  • Understand the principles of unit testing and apply the Arrange-Act-Assert pattern
  • Apply object-oriented programming concepts including abstraction and encapsulation
