C# Features Succinctly is a concise guide to the significant features packaged in C# 7, 8, and 9.

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.
