F# for C# programmers
summary
Compares C# and F# with concrete side‑by‑side code, demoing F# Interactive inside Visual Studio and VS Code (Ionide), a Roman‑numeral converter and pipeline examples, and shows the compiler infers types so code reads like scripts. Emphasizes defaults: immutability and non‑null values, algebraic types such as discriminated unions, and collection helpers like fold and pipe. Claims F# yields about 3x less code and fewer null/equals bugs — watch for demos and the exact refactor steps.
