Introduction to C#

Introduction to C#

Duration: 5 Days

Description

This hands-on course introduces the fundamentals of C# programming within the .NET ecosystem. You’ll learn how to write, structure, and run C# programs using modern development tools while building a solid foundation in object-oriented programming — covering variables, control flow, loops, methods, and classes. The course also introduces inheritance, interfaces, collections, and structs, preparing you to build real-world applications with confidence.

Audience

Built for beginners with some grounding in programming logic who want to learn C# and .NET from the ground up. Ideal for aspiring software developers, QA engineers, and IT professionals transitioning into application development on the Microsoft technology stack — no prior C# experience required.

Objectives

  • Understand the role of .NET runtime and development tools in C# programming
  • Write basic C# programs using variables, operators, and control structures
  • Implement iterative logic using different types of loops
  • Define and invoke methods with various parameter types and return values
  • Create and manipulate objects, classes, and properties
  • Apply object-oriented programming principles including encapsulation, inheritance, and polymorphism
  • Work with collections, enumerations, structs, and other advanced object features in C#

Prerequisites

Participants should be familiar with basic programming concepts such as variables, loops, and conditionals in any programming language. No prior experience with C# or the .NET framework is required. However, learners should have basic experience using a computer in a development environment, such as working with Visual Studio Code or using the command line.
