Functional programming in C# has always lived in that intriguing space between "wildly powerful" and "slightly overlooked." This session leans fully into the fun side of that. Oliver will live-code two of the most mind-bending (but surprisingly accessible!) functional techniques in modern C#: real currying/partial application/composition patterns, and the step-by-step derivation of a practical monadic workflow from plain imperative code. No grand paradigms, no theory detours, just sharp, geek-pleasing transformations that show what the language has quietly been capable of for years. If you enjoy seeing C# bent in unexpected ways (or want to pick up a few patterns you’ve probably never used), this is the talk to dive in.
