C# 6 and .NET Core 1.0

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 with deeper research into topics of this chapter.

Exercise 4.1 – test your knowledge

Use the Web to answer the following questions:

  1. Does every assembly you create have a reference to the mscorlib.dll assembly?

  2. What is the maximum number of characters that can be stored in a string?

  3. When and why should you use a SecureString?

  4. When should you use a LinkedList?

  5. When should you use a SortedDictionary class rather than a SortedList class?

  6. Why should you not use the official standard for e-mail addresses to create a regular expression for validating a user's e-mail address?

Exercise 4.2 – practice regular expressions

Create a console application named Ch04_Exercise02 that prompts the user to enter a regular expression, and then prompts the user to enter some input and compare the two for a match until the user presses Esc:

The default regular expression checks for at least...
