C# Features Succinctly is a concise guide to the significant features packaged in C# 7, 8, and 9. To help readers understand the evolution of the language, author Dirk Strauss first covers the important additions that arrived in version 7, such as tuples, pattern matching, and out variables. Next, he covers more than a dozen features in version 8, from nullable reference types to unmanaged constructed types. Finally, readers get a taste of the latest features in C# 9, and some of the productivity enhancements provided to .NET developers in Visual Studio.
