C# 9.0 in a Nutshell

Handy size to carry and seems to be well written.

I really like these C# Nutshell books. I've had several over the years, all the recent (7/8/9) versions have been excellent, and with Microsoft making a lot of changes they are great reference books.As to "not a good book to learn" reviews - true but that's true for PHP, Java and other languages. The Nutshell series explain the syntax for people who are somewhat familiar but haven't seen the latest version - or especially for C# - have experience and know from reading articles online that there is something like xxx but haven't used it and aren't sure exactly how it works. That's where these books shine. I have yet to use nullable reference types only because I've been busy on some Java code at work but once I get back in C# I'll have to look up the new stuff.I have found the books to be well written and very useful. But it's like a SQL reference guide for a major database (MS, Oracle or one of the My SQL derivatives) - you know there is a function to (think of dates or something) but don't know the parameter order - if it was C# this is the book you'd reach for. But learning C# or SQL, never. That's not the audience. If you are coming from, say, Java, this book could be very useful because you are familiar with many similar, but implemented differently, constructs and need to know "how do they do that in C#?" Likewise LINQ, which is in no other language I know of (beans and Hibernate and such have nothing similar, let alone PHP) - so this can be a good reference, but overwhelming at first (try the MS docs for the basics, then come here for the details).Recommended. Very much.Now for C# 10 and all those changes. I've been following Hanselman but I hope the author brings out a book for version 10, due out 5-6 weeks from when I write this. I pre-ordered C# 9 in a nutshell that early, I wish I could do the same for 10 so this wish is not out of line.

Ótimo livro, gosto bastante da linguagem C# e comprei esse livro que é uma das referências da linguagem. Porém é um livro sobre o C#, se vc quiser um livro que se aprofunde nos frameworks, UWP, WPF, Xamarin e etc, sugiro ir atrás de outros livros. Esse livro é sobre a linguagem C# e faz muito bem sua função.

Este es un libro increíblemente detallado. Súper extenso con todo lo relacionado con c#.

Zuerst mal, es ist wirklich kein Buch für einen Programmieranfänger. Bei einem fortgeschrittenem Programmierer sollte es sich allerdings immer in Griffweite befinden. Seitdem die Entwicklung von .NET Framework mit der Version 4.8 zu einem Ende gekommen ist, begrüße ich es sehr, dass im vorliegenden Buch .NET 5 die Grundlage ist. Wer also über die ersten Programmierschritte hinausgekommen ist, macht mit diesem Buch nichts falsch. Höchste Empfehlung!
