Functional ideas are becoming ubiquitous in the .NET world. F# is a Visual Studio language; C# 3.0 includes many functional constructs; Reactive extensions (Rx) are based on functional design and upcoming version of C# is inspired by F# asynchronous workflows.

Learning several simple functional concepts will help you understand these technologies and use them effectively. This means that the course will make you a better programmer even if you’re not going to immediately start using F#. This course is based on experience of developing commercial applications in F# and we’ll discuss good ways of introducing F# to your daily work.

Lear How To

You’ll learn how to use and understand functional programming concepts and technologies in practice on the .NET platform.

• Think in the functional way and use this thinking when designing .NET applications
• Write effective and succinct code in F#
• Combine F# functional libraries F# with object-oriented components in C#.
• Model problem domains using functional types
• Write reactive and asynchronous applications
