Functional Programming in C#: How to write better C# code

Summary

Functional Programming in C# teaches you to apply functional thinking to real-world problems using the C# language. The book, with its many practical examples, is written for proficient C# programmers with no prior FP experience. It will give you an awesome new perspective.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

About the Technology

Functional programming changes the way you think about code. For C# developers, FP techniques can greatly improve state management, concurrency, event handling, and long-term code maintenance. And C# offers the flexibility that allows you to benefit fully from the application of functional techniques. This book gives you the awesome power of a new perspective.

About the Book

Functional Programming in C# teaches you to apply functional thinking to real-world problems using the C# language. You’ll start by learning the principles of functional programming and the language features that allow you to program functionally. As you explore the many practical examples, you’ll learn the power of function composition, data flow programming, immutable data structures, and monadic composition with LINQ.

What’s Inside

• Write readable, team-friendly code
• Master async and data streams
• Radically improve error handling
• Event sourcing and other FP patterns
