C# is undeniably one of the most versatile programming languages available to engineers today. With this comprehensive guide, you'll learn just how powerful the combination of C# and .NET can be. Author Ian Griffiths guides you through C# 12.0 and .NET 8 fundamentals and techniques for building cloud, web, and desktop applications.Designed for experienced programmers, this book provides many code examples to help you work with the nuts and bolts of C#, such as generics, LINQ, and asynchronous programming features. You'll get up to speed on .NET 8 and the latest C# 11.0 and 12.0 additions, including generic math, new polymorphism options, enhanced pattern matching, and new features designed to improve productivity.This book helps you:Understand how .NET has changed in recent releases and learn what it means for application developmentSelect the appropriate C# language features for any taskLearn when to use the new features and when to stick with older onesExamine the range of functionality in .NET's class librariesApply these class libraries to practical programming tasksExplore numerous small additions to .NET that improve expressiveness
