I've been using heavily functional c# at work with LanguageExt for about a year. It has been quite painful, especially when it comes to debugging but also because things like pattern matching are really tedious (eg. imagine a class with two Eithers, now every Match needs to handle 4 possibilities when I may actually only care about 1).

Unless f# has massive advantages over c# when it comes to functional programming, I would say this paradigm is not worth it in 90% of my programming projects.
