Advanced C# Language Features

This unit explores advanced C# language constructs, object and type design patterns, collections and I/O, and developer tooling. Students extend prior fundamentals to build concise, maintainable, and debuggable applications using modern C# features and patterns.

Learning Objectives

• Analyze and design class and type hierarchies using classes, structs, records, interfaces, inheritance, namespaces, constructors, and access modifiers to create maintainable object-oriented solutions.
• Apply advanced method and member constructs—anonymous and static anonymous functions, covariant returns, ref/out references, tuples, throw expressions, and expression‑bodied members—to implement concise, correct behaviors.
• Demonstrate proficiency with collections, strings, and I/O by implementing operations using lists, dictionaries, arrays and collection initializers, streams, console input, string/char searching and formatting.
• Evaluate and employ developer tools and patterns—events/delegates, partial methods, static members, debugging techniques, WPF data binding, and C# notebook/online environments—to test, troubleshoot, and deliver responsive applications.
