▶Book Description
The C# programming language is often developers’ primary choice for creating a wide range of applications for desktop, cloud, and mobile. In nearly two decades of its existence, C# has evolved from a general-purpose, object-oriented language to a multi-paradigm language with impressive features.

This book will take you through C# from the ground up in a step-by-step manner. You'll start with the building blocks of C#, which include basic data types, variables, strings, arrays, operators, control statements, and loops. Once comfortable with the basics, you'll then progress to learning object-oriented programming concepts such as classes and structures, objects, interfaces, and abstraction. Generics, functional programming, dynamic, and asynchronous programming are covered in detail. This book also takes you through regular expressions, reflection, memory management, pattern matching, exceptions, and many other advanced topics. As you advance, you'll explore the .NET Core 3 framework and learn how to use the dotnet command-line interface (CLI), consume NuGet packages, develop for Linux, and migrate apps built with .NET Framework. Finally, you'll understand how to run unit tests with the Microsoft unit testing frameworks available in Visual Studio.

By the end of this book, you’ll be well-versed with the essentials of the C# language and be ready to start creating apps with it.

▶What You Will Learn
- Get to grips with all the new features of C# 8
- Discover how to use attributes and reflection to build extendable applications
- Utilize LINQ to uniformly query various sources of data
- Use files and streams and serialize data to JSON and XML
- Write asynchronous code with the async-await pattern
- Employ .NET Core tools to create, compile, and publish your applications
- Create unit tests with Visual Studio and the Microsoft unit testing frameworks

▶Key Features
- Learn the fundamentals of C# with the help of easy-to-follow examples and explanations
- Leverage the latest features of C# 8, including nullable reference types, pattern matching enhancements, and asynchronous streams
- Explore object-oriented programming, functional programming, and multithreading concepts

▶Who This Book Is For
If you have little experience in coding or C# and want to learn the essentials of C# programming to develop powerful programming techniques, this book is for you. It will also help aspiring programmers to write scripts or programs to accomplish specific tasks.

출판사 서평

▶ Preface
C# is a general-purpose, multi-paradigm programming language that combines object-oriented, imperative, generic, functional, declarative, and dynamic programming. Soon after its release, C# became one of the top choices for developers for writing a large variety of types of applications. Although it is not the only language targeting the CLI (the others include VB.NET and F#), it is the primary choice for writing .NET applications for desktop, web, cloud, and mobile platforms.

Over the years, the language has evolved gradually but steadily. Although initially it was an object-oriented programming language, new versions have opened up the language to new paradigms such as generic, functional, and dynamic programming. New language features and more concise syntax have also been added regularly. With its release as an open source project of the .NET Compiler Platform, also known as Roslyn, which is a set of compilers and code analysis APIs for C# and VB.NET, the language has entered a new open era with the community deeply involved in the development of the language.

The current version of the language is known as C# 8. This was released in September 2019 for .NET Core 3.0 and requires Visual Studio 2019 16.3 or a newer version. C# 8 can also be used with .NET Framework, although not all features are available. That is because they required runtime changes, which was something Microsoft did not want to do due to its intent to no longer invest in .NET Framework (other than long-time support) and turn .NET Core into the one framework used to target all platforms and types of applications. This framework will be known simply as .NET.

This book is designed to help you learn the language from scratch and eventually master all its multi-paradigm programming aspects. We start with the very basics: data types, statements, and other building blocks. We then continue with object-oriented concepts such as classes, interfaces, inheritance, and polymorphism. We cover generics, functional programming and LINQ, reflection and dynamic programming, and more advanced topics, such as resource management, pattern matching, concurrency and asynchronous programming, error handling, and serialization. Toward the end of the book, we give special attention to the new features introduced in C# 8. Last, but not least, we discuss unit testing and how you can write unit tests for your C# code. At the end of each chapter,
we provide you with a set of questions to help you assess what you learned in that chapter.

The book contains many code snippets that are designed to help you easily understand and learn all the language features. All of them are available in the source code that accompanies the book. You will need either Visual Studio or Visual Studio Code to try them. Alternatively, you can use an online compiler, the primary choice in this case being https://sharplab.io/.
