▶Book Description
In C# 8.0 and .NET Core 3.0 ？ Modern Cross-Platform Development, Fourth Edition, expert teacher Mark J. Price gives you everything you need to start programming C# applications.

This latest edition uses the popular Visual Studio Code editor to work across all major operating systems. It is fully updated and expanded with new chapters on Content Management Systems (CMS) and machine learning with ML.NET.

The book covers all the topics you need. Part 1 teaches the fundamentals of C#, including object-oriented programming, and new C# 8.0 features such as nullable reference types, simplified switch pattern matching, and default interface methods. Part 2 covers the .NET Standard APIs, such as managing and querying data, monitoring and improving performance, working with the filesystem, async streams, serialization, and encryption. Part 3 provides examples of cross-platform applications you can build and deploy, such as web apps using ASP.NET Core or mobile apps using Xamarin.Forms. The book introduces three technologies for building Windows desktop applications including Windows Forms, Windows Presentation Foundation (WPF), and Universal Windows Platform (UWP) apps, as well as web applications, web services, and mobile apps.

▶What You Will Learn
- Build cross-platform applications for Windows, macOS, Linux, iOS, and Android
- Explore application development with C# 8.0 and .NET Core 3.0
- Explore ASP.NET Core 3.0 and create professional web applications

▶What this book covers
- Chapter 1, Hello, C#! Welcome, .NET!, is about setting up your development environment and using Visual Studio Code to create the simplest application possible with C# and .NET. You will learn how to write and compile code on any of the supported operating systems: Windows, macOS, and Linux variants. You will also learn the best places to look for help.

- Chapter 2, Speaking C#, introduces the versions of C# and has tables of which version introduced new features, and then explains the grammar and vocabulary that you will use every day to write the source code for your applications. In particular, you will learn how to declare and work with variables of different types, and about the big change in C# 8.0 with the introduction of nullable reference types.

- Chapter 3, Controlling Flow and Converting Types, covers using operators to perform simple actions on variables including comparisons, writing code that makes decisions, repeats a block of statements, and converts between types. It also covers writing code defensively to handle errors when they inevitably occur.

- Chapter 4, Writing, Debugging, and Testing Functions, is about following the Don't Repeat Yourself (DRY) principle by writing reusable functions. You will also learn how to use debugging tools to track down and remove bugs, monitoring your code while it executes to diagnose problems, and rigorously testing your code to remove bugs and ensure stability and reliability before it gets deployed into production.

- Chapter 5, Building Your Own Types with Object-Oriented Programming, discusses all the different categories of members that a type can have, including fields to store data and methods to perform actions. You will use OOP concepts, such as aggregation and encapsulation. You will learn language features such as tuple syntax support and out variables, and default literals and inferred tuple names.

- Chapter 6, Implementing Interfaces and Inheriting Classes, explains deriving new types from existing ones using object-oriented programming (OOP). You will learn how to define operators and local functions, delegates and events, how to implement interfaces about base and derived classes, how to override a type member, how to use polymorphism, how to create extension methods, and how to cast between classes in an inheritance hierarchy.

- Chapter 7, Understanding and Packaging .NET Types, introduces the versions of .NET Core and has tables of which version introduced new features, then presents .NET Core types that are compliant with .NET Standard, and how they relate to C#. You will learn how to deploy and package your own apps and libraries.

- Chapter 8, Working with Common .NET Types, discusses the types that allow your code to perform common practical tasks, such as manipulating numbers and text, storing items in collections, and implementing internationalization.

- Chapter 9, Working with Files, Streams, and Serialization, talks about interacting with the filesystem, reading and writing to files and streams, text encoding, and serialization formats like JSON and XML.

- Chapter 10, Protecting Your Data and Applications, is about protecting your data from being viewed by malicious users using encryption and from being manipulated or corrupted using hashing and signing. You will also learn about authentication and authorization to protect applications from unauthorized users.

- Chapter 11, Working with Databases Using Entity Framework Core, explains reading and writing to databases, such as Microsoft SQL Server and SQLite, using the objectrelational mapping (ORM) technology named Entity Framework Core.

- Chapter 12, Querying and Manipulating Data Using LINQ, teaches you Language INtegrated Queries (LINQ)―language extensions that add the ability to work with sequences of items and filter, sort, and project them into different outputs.

출판사 서평

▶ Preface
There are C# books that are thousands of pages long that aim to be comprehensive references to the C# programming language and the .NET Framework.

This book is different. It is concise and aims to be a brisk, fun read that is packed with practical hands-on walkthroughs of each subject. The breadth of the overarching narrative comes at the cost of some depth, but you will find many signposts to explore further if you wish. This book is simultaneously a step-by-step guide to learning modern C# proven practices using cross-platform .NET and a brief introduction to the main types of applications that can be built with them. This book is best for beginners to C# and .NET, or programmers who have worked with C# in the past but feel left behind by the changes in the past few years. If you already have experience with C# 5.0 or later, then in the first topic of Chapter 2, Speaking C#, you can review tables of the new language features and jump straight to them. If you already have experience with .NET Core 1.0 or later, then in the first topic of Chapter 7, Understanding and Packaging .NET Types, you can review tables of the new platform features and jump straight to them.

I will point out the cool corners and gotchas of C# and .NET, so you can impress colleagues and get productive fast. Rather than slowing down and boring some readers by explaining every little thing, I will assume that you are smart enough to Google an explanation for topics that are related but not necessary to include in a beginner-to-intermediate guide.

You can download solutions for the step-by-step guided tasks and exercises from the following GitHub repository. If you don't know how, then I provide instructions on how to do this using Visual Studio Code at the end of Chapter 1, Hello, C#! Welcome, .NET!
