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.

Raising and handling events


Methods are often described as actions that an object can do. For example, a List class can add an item to itself or clear itself.

Events are often described as actions that happen to an object. For example, in a user interface, a Button has a Click event, click being something that happens to a button.

Another way of thinking of events is a way of exchanging messages between two objects.

Calling methods using delegates

You have already seen the most common way to call or execute a method: use the "dot" syntax to access the method using its name.

The other way to call or execute a method is to use a delegate. If you have used languages that support function pointers, then you can think of a delegate as being a type-safe method pointer. In other words, a delegate is just the memory address of a method that matches the same signature as the delegate.

For example, imagine there is a method that must have a string passed as its only parameter and it returns an int:

public...
