OOP is very natural in F#, so it's not that. Interacting with .NET is not an issue. Interacting with a third-party library can sometimes be an issue, if they're doing a bunch of funky C# stuff. For my own use cases, I haven't needed to pull in a bunch of C# developed, third-party libraries. When I did, for example Silk.NET's window bindings, it was easier to just write my own. I couldnimagine that's different for some more industrial use cases though.
