    > I don't really get it

To me it makes sense because C# is a very general purpose language that has many audiences. Desktop GUI apps, web APIs, a scripting engine for gaming SDKs, console apps.

It does each reasonably well (with web APIs being where I think they truly shine).

    > Was a functional approach really so 'difficult'

It is surprisingly difficult for folks to grasp functional techniques and even writing code that uses `Func`, `Action`, and delegates. Devs have no problem consuming such code, but writing such code is a different matter altogether; there is just very little training for devs to think functionally. Even after explaining why devs might want to write such code (e.g. makes testing much easier), it happens very, very rarely in our codebase.
