F# for the curly brace developer
summary
Demonstrates a concrete line-by-line port of a C# CSV-to-email program into F#, claims a production F# stack runs on Linux, and shows the actual code on GitHub. Converts C# classes to records with value equality, replaces mutable loops with a pipelined sequence of distinct → map → filter, adds a FSharp.Data type provider to generate strongly typed CSV rows, swaps interfaces for function types, uses discriminated unions for richer results and points to PSeq parallelization as an easy scaling step.
