Using F# on Azure Functions in Production

on YouTube ↗53m

" summary

Builds an automated changelog service in F# that calls Octopus Deploy, TeamCity and JIRA APIs, parses merge commits and DB migration tags, and emails a generated changelog so customers can approve deployments. Uses F# JSON and SQL type providers for compile‑time safety, precompiled Azure Functions deployed as lightweight DLLs, and the actual Azure Functions runtime to run and debug locally. Service reduces manual QA steps and enables feature‑driven releases (several deploys/week, 20 minutes from change to production), with a noted friction: Azure Functions v1 F# dependency version mismatch.
