Foundations of Object-Oriented Programming in C# and .NET

Want to transition from writing simple scripts to building robust, scalable software? Object-oriented programming (OOP) is the industry-standard paradigm that makes modern software development possible. This text-based course guides you from absolute beginner concepts to designing structured, real-world C# applications. You will learn how to think in objects, organize your code logically, and leverage modern .NET features to build clean, maintainable software. What you will learn: 1. Understand foundational OOP pillars including encapsulation, inheritance, polymorphism, and abstraction. 2. Create reusable classes, objects, and interfaces using modern C# syntax. 3. Apply modern C# features such as records, init-only properties, and nullable reference types for safer code. 4. Implement clean code principles to write readable and easily testable C# programs. 5. Structure .NET Core applications from scratch using contemporary project organization. 6. Practice your skills with written coding exercises and step-by-step code analysis. Starting with basic definitions and syntax, this course guides you through core object-oriented concepts before introducing modern C# design patterns. You will read clear explanations, analyze practical code snippets, and complete written review exercises to solidify your understanding. This course is designed for beginners new to object-oriented programming or those transitioning to C# and .NET. No prior OOP experience is required, though a basic familiarity with programming fundamentals is helpful. Start reading today to build a strong foundation in modern C# software development.
