Many thanks to Microsoft, especially Microsoft Research, and Don Syme for developing F#, a functional programming that meets OOP nicely and truly pragmatic! I would like to give special thanks to Packt for giving me the chance to write this wonderful book and Nikhil for his continuous support and always giving me constructive feedback. I also would like to give a big huge thanks for my lovely wife, Dini Kusumawardhono, for always giving me unconditional love and support during the writing of this book and also her continuous understanding every day. I would like to dedicate this book to software development communities in Indonesia, and to all of the F# developer communities around the world. F# rocks!
