Functional Programming Using F#

This comprehensive introduction to the principles of functional programming using F# shows how to apply basic theoretical concepts to produce succinct and elegant programs. It demonstrates the role of functional programming in a wide spectrum of applications including databases and systems. Coverage also includes advanced features in the .NET library, the imperative features of F# and topics such as text processing, sequences, computation expressions and asynchronous computation. With a broad spectrum of examples and exercises, the book is perfect for courses in functional programming and for self-study. Enhancing its use as a text is an accompanying website with downloadable programs, lecture slides, mini-projects and links to further F# sources. "I highly recommend this textbook introducing functional programming with F#. Building on core functional concepts, Hans and Michael introduce topics carefully and with an eye to both theory and practice. The book gives an excellent basis for programming in today's strongly typed multi-paradigm languages and will enable the student to explore many further applied programming domains." Don Syme, Principal Researcher and F# Designer, Microsoft Research "Whereas the power of functional programming has been widely recognized only in recent years, Hansen and Rischel bring decades of experience to the subject. Using F#, they teach how to employ a range of elegant functional programming techniques and show how a host of realistic problems can be solved functionally, drawing on the rich libraries of the .NET platform."
