C# OOP and Framework Essentials

This unit advances students from basic syntax to intermediate C# and .NET concepts, emphasizing object-oriented design, member semantics, and common framework services. Students will build reusable types (classes, structs, interfaces, delegates), handle errors and I/O, and begin integrating code into Visual Studio projects and simple XAML/UWP or web interfaces with attention to secure coding practices.

Learning Objectives

• Analyze and compare member and method semantics (static vs. instance, named parameters, access modifiers) to design encapsulated and maintainable C# types
• Apply object-oriented constructs—including inheritance, polymorphism, interfaces, delegates, indexers, structs, and enumerated flags—to implement reusable and extensible components
• Demonstrate data handling and robustness by implementing serialization/StreamWriter I/O, custom exceptions, collection manipulation (sorting, generics, variance), and appropriate argument/parameter usage
• Evaluate and use Visual Studio tooling and .NET frameworks to create basic XAML/UWP and web application interfaces, employ data binding and commands, and apply secure application practices
