Today, applications are performing more complicated analyses on larger sets of data than ever before. As our applications continue to grow we need tools to bring back simplicity (and a bit of sanity!) to our code. F# is the best tool for the job, providing powerful support for handling big data, immutable data structures, and functional-style programming—without the boilerplate needed by other languages. In this session, we explore how you can use F# in your own application to manage complexity, mixing it seamlessly with your existing C# or Visual Basic code.
