✦ Synopsis

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# 8.0 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, dynamic typing, nullable reference types, and asynchronous programming features. You'll get up to speed on .NET Core, LINQ, and the latest C# 8.0 additions, including asynchronous streams, pattern matching, default interface assignment, ranges and new indexing syntax, and changes in the .NET tool chain.

Discover how C# supports fundamental coding features such as classes, other custom types, collections, and error handling
Learn how to write high-performance memory-efficient code with .NET Core's Span and Memory types
Query and process diverse data sources such as in-memory object models, databases, data streams, and XML documents with LINQ
