Are there any F# APIs? I tried to introduce F# to a project but between all needed APIs written in C#/OOP style and only mild interest from a lot of developers and managers I couldn't really justify the added friction.

If there were a ton of F# libraries that showed how to create functional APIs people could learn from them by using them the same way a lot people learn OOP by using APIs.

As it is now the only way to get into F# is to have a group who really wants to do it and learn. Otherwise it's just an uphill battle.
