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.

Selection statements


Every application needs to be able to select from choices and branch along different code paths. The two selection statements in C# are if and switch, also known as if-else and switch-case. You can use if for all your code but switch can simplify your code in some common scenarios.

Start Microsoft Visual Studio 2015. In Visual Studio, press Ctrl + Shift + N or choose File | New | Project….

In the New Project dialog, in the Installed Templates list, select Visual C#. In the list at the center, select Console Application, type the name Ch03_SelectionStatements, change the location to C:\Code, type the solution name Chapter03, and then click on OK.

At the top of the Program.cs file, statically import the System.Console type, as follows:

using static System.Console;

The if-else statement

The if-else statement determines which branch to follow by evaluating a Boolean expression. The else block is optional. if-else statements can be nested and combined. Each Boolean expression can...
