C# 9.0 Pocket Reference: Instant Help for C# 8.0 Programmers
by Joseph Albahari and Ben Albahari
When you have questions about C# 9.0 or [[.NET 5, this best-selling guide has the answers you need. C# is a language of unusual flexibility and breadth, but with its continual growth there's so much more to learn. In the tradition of O'Reilly's Nutshell guides, this thoroughly updated edition is simply the best one-volume reference to the C# language available today.
Organized around concepts and use cases, C# 9.0 in a Nutshell provides intermediate and advanced programmers with a concise map of C# and .NET that also plumbs significant depths.
Joseph Albahari is author of C# 8.0 in a Nutshell, C# 8.0 Pocket Reference, and LINQ Pocket Reference (all from O'Reilly). He also wrote LINQPad, the popular code scratchpad and LINQ querying utility.
“C# is a general-purpose, type-safe, primarily object-oriented programming language, the goal of which is programmer productivity. To this end, the language balances simplicity, expressiveness, and performance. C# 9 is designed to work with the Microsoft .NET 5 runtime (whereas C# 8 targets .NET Core 3, and C# 7 targets .NET Core 2 and Microsoft .NET Framework 4.6/4.7/4.8).”
Note: The programs and code snippets in this book mirror those in Chapters 2 through 4 of C# 9.0 in a Nutshell and are all available as interactive samples in LINQPad. Working through these samples in conjunction with the book accelerates learning in that you can edit the samples and instantly see the results without needing to set up projects and solutions in Visual Studio.
To download the samples, click the Samples tab in LINQPad and then click “Download more samples.” LINQPad is free — go to www.linqpad.net.
