C# 6 and .NET Core 1.0: Modern Cross-Platform Development

Overview of this book

With the release of .NET Core 1.0, you can now create applications for Mac OS X and Linux, as well as Windows, using the development tools you know and love. C# 6 and .NET Core 1.0 has been divided into three high-impact sections to help start putting these new features to work. First, we'll run you through the basics of C#, as well as object-orient programming, before taking a quick tour through the latest features of C# 6 such as string interpolation for easier variable value output, exception filtering, and how to perform static class imports. We'll also cover both the full-feature, mature .NET Framework and the new, cross-platform .NET Core. After quickly taking you through C# and how .NET works, we'll dive into the internals of the .NET class libraries, covering topics such as performance, monitoring, debugging, internationalization, serialization, and encryption. We'll look at Entity Framework Core 1.0 and how to develop Code-First entity data models, as well as how to use LINQ to query and manipulate that data. The final section will demonstrate the major types of applications that you can build and deploy cross-device and cross-platform. In this section, we'll cover Universal Windows Platform (UWP) apps, web applications, and web services. Lastly, we'll help you build a complete application that can be hosted on all of today's most popular platforms, including Linux and Docker. By the end of the book, you'll be armed with all the knowledge you need to build modern, cross-platform applications using C# and .NET Core.

Talking about OOP


An object in the real world is a thing, like a car or a person. An object in programming often represents something in the real world, such as a product or bank account, but can also be something more abstract.

In C#, we use a class (usually) or a struct (rarely) to define each type of object. You can think of a type as being a blueprint or template for an object.

Encapsulation is the combination of the data and actions that are related to an object. For example, a BankAccount type might have data such as Balance and AccountName, as well as actions such as Deposit and Withdraw. When encapsulating, you often want to control what is allowed to access those data and actions.

Composition is about what an object is made of. For example, a car is composed of different parts such as four wheels, several seats, an engine, and so on.

Aggregation is about what is related to an object. For example, a person could sit in the driver's seat and becomes the car's driver.
