Preface
C# is a language targeted at developers for the Microsoft .NET platform. Microsoft
portrays C# as a modern and innovative language for .NET development and continues to
deliver on that in C# 6.0 with features that help support dynamic programming, parallel
programming, and writing less code. C# still allows for both declarative and functional
styles of programming, and still includes great object-oriented features as well. In short,
C# allows you to use the style of programming that fits your particular problem.
We started writing this book together based on programming problems we ran into when
we were first learning C#, and we have continued to expand it based on new challenges
and capabilities in the language. In this edition, we have reworked the approach of many
solutions to take advantage of the latest innovations in C# like the new expression-level
(nameof, string interpolation, null conditional, index initializers), member declaration
(auto-property initializers, getter-only auto-properties, expression-bodied function
members), and statement-level (exception filters) features. We have also incorporated new
uses of dynamic programming (C# 4.0) and asynchronous programming (C# 5.0) into both
existing and new recipes to help you understand how to use these language features.
We hope that these additions will help you get past some of the common (and not-so-
common) pitfalls and questions everyone has when learning C# for the first time,
exploring a new capacity of the language, or working on the slightly off-the-beaten-path
items that come up during a development cycle. There are recipes addressing things we
found missing from the .NET Framework Class Library (FCL), even though Microsoft has
provided tons of functionality to keep folks from reinventing the wheel. Some of these
solutions you might immediately use, and some may never darken your door, but we hope
this book helps you get the most out of C# and the .NET Framework.
The book is laid out with respect to the types of problems you will solve as you progress
through your life as a C# programmer. These solutions are called recipes; each recipe
consists of a single problem, its solution, a discussion of the solution and other relevant
related information, and finally, a list of resources such as where in the FCL you can find
more information about the classes used, other books addressing the topic, related articles,
and other recipes. The question/answer format provides complete solutions to problems,
making the book easy to read and use. Nearly every recipe contains a complete,
documented code sample, showing you how to solve the specific problem, as well as a
discussion of how the underlying technology works and a list of alternatives, limitations,
and other considerations when appropriate.
