F#+ is a base library that aims to take F# to the next level of functional programming.

What if we imagine F# as more than it is?

F#+ builds upon FSharp, using generic programming techniques to help you avoid boiler plate code. However, by naming conventions and signatures it can be seen to 'enhance' rather than 'replace' existing patterns as much as possible.

Getting started is easy since you can start with enjoying some of the extensions and generic functions, but you will find other parts of F#+ unfold before you and become useful the deeper in you get.

See the documentation for more details.
