Functional programming with F#

Functional programming is being increasingly used in domains such as finance, gaming and web and mobile development. It makes solving complex problems simpler and allows developers to easily write maintainable and robust code. In this hands-on training you will learn how and why to write real world functional programs on the .NET platform with the F# language.


You have development experience on the .NET platform and (preferably) the C# language. Now you are interested to learn another programming paradigm next to object oriented programming and get familiar with the F# language.
