C# 7 and .NET Core: Modern Cross-Platform Development - Second E...

2017年第二版， PDF格式 What this book covers Chapter 1, Hello, C#! Welcome, .NET Core!, is about setting up your development environment and using various tools to create the simplest application possible with C#. You will learn how to write and compile code using Visual Studio 2017 on Windows, or Visual Studio Code on macOS, Linux, or Windows. You will learn about the different .NET technologies: .NET Framework, .NET Core, .NET Standard, and .NET Native. Chapter 2, Speaking C#, is about the C# language---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. Chapter 3, Controlling Flow, Converting Types, and Handling Exceptions, is about writing code that makes decisions, repeats a block of statements, converts between types, and handles errors. You will also learn the best places to look for help. Chapter 4, Using .NET Standard Types, is about commonly used .NET Core types that are part of .NET Standard and how they are related to C#. You will learn about the .NET Standard class library assemblies and the NuGet packages of types that allow your applications to connect existing components to perform common practical tasks, such as manipulating text, storing items in collections, and implementing internationalization. Chapter 5, Debugging, Monitoring, and Testing, is about debugging tools, monitoring, diagnosing problems, and testing your code to remove bugs and ensuring high performance, stability, and reliability. Chapter 6, Building Your Own Types with Object-Oriented Programming, is about 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 about the C# 7 language features such as tuple syntax support and out variables. Chapter 7, Implementing Interfaces and Inheriting Classes, is about deriving new types from existing ones using object-oriented programming (OOP). You will learn how to define operators and C# 7 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 8, Working with Databases Using Entity Framework Core, is about reading and writing to databases, such as Microsoft SQL Server and SQLite, using the object-relational mapping technology known as the Entity Framework Core. Chapter 9, Querying and Manipulating Data with LINQ, is about Language INtegrated Query (LINQ)---language extensions that add the ability to work with sequences of items and filter, sort, and project them into different outputs. Chapter 10, Working with Files, Streams, and Serialization, is about managing the filesystem, reading and writing to files and streams, text encoding, and serialization. Chapter 11, Protecting Your Data, is about protecting your data from being viewed by malicious users using encryption and from being manipulated or corrupted using hashing and signing. Chapter 12, Improving Performance and Scalability with Multitasking, is about allowing multiple actions to occur at the same time to improve performance, scalability, and user productivity. Chapter 13, Building Universal Windows Platform Apps Using XAML, is about learning the basics of XAML that can be used to define the user interface for a graphical app for the Universal Windows Platform (UWP). This app can then run on Windows 10, Windows 10 Mobile, Xbox One, and even HoloLens. Chapter 14, Building Web Applications Using ASP.NET Core MVC, is about learning the basics of building web applications with a modern HTTP architecture on the server side using ASP.NET Core MVC. You will learn about the startup configuration, authentication, routes, models, views, and controllers that make up ASP.NET Core MVC. Chapter
