IME most in DI heavy C# code (e.g. Asp.Net Core) you're using classes but those classes are really just a set of named functions bundled together with their dependencies, not unlike a closure. It's not very common to see classes that are stateful. I've never tried it but I'm fairly certain that most C# IOC containers should allow you to resolve functions if you really wanted to go that route.
