And all .NET programmers will find F# an exciting real-world alternative to C# and Visual Basic. This book is likely to have many imitators, but few true competitors. Written by F# evangelist Rob Pickering, and tech reviewed by F#'s inventor, Don Syme, this is an elegant, comprehensive introduction to all aspects of the language and an incisive guide to using F# for real-world professional development. F# is the future of programming (not just on .NET), and the future is now.
