Functional Programming with C#

All Indian Reprints of O'Reilly are printed in Grayscale

After decades of relative obscurity, functional programming is finally coming into its own. With concise, easy-to-read code that supports asynchronous, concurrent processing, aspects of functional programming have begun to appear in several traditionally object-oriented languages such as C# and Java. This practical book shows C# programmers how to use functional programming features without having to navigate an entirely new language.

Because of the shared runtime environment common to C# and F# languages, it's possible to use most of F#'s functional features in C# as well. Author Simon J. Painter explains how you can write functional code in C# right away, without having to install dependencies or features newer than .NET 3.

You'll learn why functional programming concepts can bring immediate benefit to your work.

• Learn what functional programming is and how it originated
• Discover features of the functional paradigm using a more familiar language
• Start coding functionally in C# right away, without relying on third-party libraries
• Write code that's more robust, less error prone, and easier to test
• Examine less conventional ways to look at structures available in C#
• Explore the practicalities of using functional C# in a business environment

About the Author

Simon J. Painter has been developing professionally for far, far too long now (well, since 2005) and has worked with every version of .NET ever released (including Compact Framework - remember that?) in around a dozen different industries. As well as his day job, he also appears regularly at user groups and conferences to give talks on Functional Programming and general .NET topics. Before becoming a professional, Simon had been a coding enthusiast since he was old enough to read his Dad's copy of the Sinclair ZX Spectrum BASIC handbook. Besides code, he loves Music, Cryptic Crosswords, Fighting Fantasy Gamebooks and far more coffee than is likely to be healthy for him. He lives in a small town in the UK, with his wife and children.
