Discover what’s new in C# and .NET for Windows programming. This book is a condensed code and syntax reference to the C# programming language, updated with the latest features of version 10 for .NET 6.
You’ll review the essential C# 10 and earlier syntax, not previously covered, in a well-organized format that can be used as a handy reference. Specifically, unions, generic attributes, CallerArgumentExpression, params span, Records, Init only setters, Top-level statements, Pattern matching enhancements, Native sized integers, Function pointers and more.
You’ll find a concise reference to the C# language syntax: short, simple, and focused code examples; a well laid out table of contents; and a comprehensive index allowing easy review. You won’t find any technical jargon, bloated samples, drawn-out history lessons, or witty stories. What you will find is a language reference that is to the point and highly accessible.
The book is a must-have for any C# programmer.

What You Will Learn
 

• Employ nullable reference types
• Work with ranges and indices
• Apply recursive patterns to your applications
• Use switch expressions

Who This Book Is For

 Those with some experience in programming, looking for a quick, handy reference. Some C# or .NET recommended but not necessary.
