Functional Programming in C#—Exploring Advanced Topics

Explores five advanced functional programming concepts in C# and ASP.NET Core: immutability to avoid state changes, higher-order functions for code reuse, pure functions for predictability, Railway-Oriented Programming for exception-free error handling, and lazy evaluation for performance optimization. Each concept is demonstrated with practical code examples comparing traditional object-oriented approaches with functional alternatives, highlighting how functional programming can lead to more reliable, testable, and maintainable software.
