C# Fundamentals OOP for Absolute Beginners 35+Practice Test

This course is designed for absolute beginners who want to build a strong and correct foundation in C# programming and Object‑Oriented Programming (OOP) using the .NET Framework. No prior programming experience is required.

The course begins with a clear explanation of .NET Framework architecture, helping you understand how C# applications work internally. You will learn about the Common Language Runtime (CLR), MSIL, Just‑In‑Time (JIT) compilation, and the Base Class Library (BCL)—concepts that are often skipped but are essential for writing efficient and reliable applications.

Once the fundamentals are clear, the course moves into C# language basics. You will learn data types, implicit and explicit casting, value types vs reference types, strings and StringBuilder, boxing and unboxing, constants, enums, operators, control statements, arrays, methods, and overall program execution flow. You will also learn how to write, compile, and run C# programs using Visual Studio 2022 and the command‑line compiler.

The second half of the course focuses deeply on Object‑Oriented Programming concepts. You will work with classes and objects, constructors and destructors, properties, static members, garbage collection, inheritance, abstract classes, interfaces, polymorphism, and type casting. Each topic is explained step by step with clear examples to ensure confidence.

To reinforce learning, the course includes 35+ practice tests to validate your understanding and prepare you for interviews and advanced C# topics. This course serves as a perfect foundation for learning Collections, LINQ, ADO .NET, ASP.NET, and enterprise application development.
