Functional Techniques for C#

on YouTube ↗58m

" summary

Explains how to apply C# functional techniques (C# 3 lambdas and LINQ) to real code: currying for clearer intent, delegate vs Expression trees (compile to delegates or translate to SQL), and when to prefer immutability or avoid tail recursion. Shows the interactive window, an inside-out refactoring that passes lambdas into a generic base EF repository with four generics, and a pattern that returns a Result container (success/value/exception) instead of throwing across layer boundaries.
