Explore the evolution and challenges of Dependency Injection in this 56-minute conference talk by Mark Seemann at NDC Conferences. Delve into the intersection of Dependency Injection and functional programming, examining how these concepts have shaped software development over the past decade. Discover alternative approaches to controlling non-deterministic behavior and learn how functional solutions can be applied to object-oriented programming. Through code examples primarily in C#, gain insights into advanced concepts such as lambda calculus, Greek terminology, Haskell, F#, and monads. Uncover the ultimate implications of these programming paradigms and broaden your understanding of modern software architecture techniques.
