I have to admit I only used F# on a small project a few years back, but the type providers made the job super simple - the job was basically generating some fancy reports from multiple data sources and being able to just specify database connection strings and have everything work in the IDE/compiler was a huge win. Setting up CI was a bit of a PITA because I remember needing to spinup a DB to create schema, there was some option to do it from schema directly but didn't want to waste time.
