When you have questions about C# 12 or .NET 8, this best-selling guide has the answers you need. C# is a language of unusual flexibility and breadth, and with its continual growth, there's always 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. Aimed at intermediate and advanced programmers, this is a book whose explanations get straight to the point, covering C#, the CLR, and the core .NET libraries in depth without long intros or bloated samples. This book targets intermediate to advanced audiences. No prior knowledge of C# is required, but some general programming experience is necessary. For the beginner, this book complements, rather than replaces, a tutorial-style introduction to programming. This book is an ideal companion to any of the vast array of books that focus on an applied technology such as ASP.NET Core or Windows Presentation Foundation (WPF). C# 12 in a Nutshell covers the areas of the language and .NET that such books omit, and vice versa.
