You have been exposed to just about every core feature of the F# programming language and seen how to program in the functional, imperative, and object-oriented styles. However, in order to develop a deep understanding of a language, you need to actually go out and use it. If you don’t have an F# starter project in mind, well, this chapter should hopefully serve as the next-best thing.

This chapter focuses on the application of the F# programming language. However, there is not a canonical F# application. The language is well suited across multiple domains and industries. Yet in all cases, F# is best suited for the computational core of a program, or the numeric heavy lifting and data processing.
