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.

Practicing and exploring


Test your knowledge and understanding by answering some questions, get some hands-on practice, and explore this chapter's topics with deeper research.

Exercise 15.1 – test your knowledge

Answer the following questions:

  1. What platforms are supported by .NET Core and ASP.NET Core?

  2. What command downloads dependent packages for a project?

  3. What file does project directory require in order to restore packages?

  4. What command will show the currently installed versions of .NET?

  5. What command will switch to a different version of .NET?

Exercise 15.2 – practice transferring an existing ASP.NET application

Take the ASP.NET Core application that we created in Chapter 14, Building Web Applications and Services Using ASP.NET Core, restore its packages, and host it in the Kestrel web server.

What happens? Why?

Note

The project uses a database connection string that attempts to connect to a Microsoft SQL Server LocalDb instance, but Mac OS X does not support this. So, an unhandled exception is...
