Thinking Functionally with C#

on YouTube ↗43m

" summary

Claims that C# can be written functionally for more predictable, testable code and shows concrete patterns: use LINQ aggregate and zip instead of for loops, replace ifs with switch expressions replacing ifs, represent errors with a Result/discriminated union style monad that binds or short‑circuits. Demonstrations include immutable state via creating new objects (Doctor Who example), trampolined loops for indefinite iteration, and composition of small pure functions; notes pragmatic limits (interop, performance and existing imperative APIs) and gives working C# idioms.
