Introduction

This series of posts will introduce you to the world of functional programming (FP) in F#. Rather than start with theory or formal definitions, we will look at some typical business problems and explore how we can use some of the exciting functional programming features in F# to solve them.

No previous experience of functional programming or F# are required.
