As a 20+ year C# developer I’ve tried several times to learn/use F#. Despite being interested in FP, my brain is having trouble figuring out how to structure my code in F#. In C# I’d either build a service (or use the mediator pattern) for the domain and a repository for data access. With F# it’s functions all the way down and it feels unnatural (as silly as that may sound).

The secret is currying. Replace your DI for currying and you'll start to see somewhat similar patterns

By the way, I consider https://www.bartoszsypytkowski.com/dealing-with-complex-depe... to be the canonically correct way to do DI when you want to inject more than like two dependencies.
