C# 7.0 represents the sixth major update to Microsoft’s flagship programming language, positioning C# as a language with unusual flexibility and breadth. At one end, it offers high-level abstractions such as query expressions and asynchronous continuations, while at the other end, it allows low-level efficiency through constructs such as custom value types and optional pointers. The price of this growth is that there’s more than ever to learn. Although tools such as Microsoft’s IntelliSense—and online references—are excellent in helping you on the job, they presume an existing map of conceptual knowledge. This book provides exactly that map of knowledge in a concise and unified style—free of clutter and long introductions. Like the past four editions, C# 7.0 in a Nutshell is organized around concepts and use cases, making it friendly both to sequential reading and to random browsing. It also plumbs significant depths while assuming only basic background knowledge— making it accessible to intermediate as well as advanced readers. This book covers C#, the CLR, and the core Framework assemblies. We’ve chosen this focus to allow space for difficult topics such as concurrency, security, and application domains—without compromising depth or readability. Features new to C# 6 and C# 7 and the associated Framework are flagged so that you can also use this book as a C# 5 and C# 6 reference. helping you on the job, they presume an existing map of conceptual knowledge.
