C# 7.1 and .NET Core 2.0 ??? Modern Cross-Platform Development - Third Edition

By: Mark J. Price

Overview of this book

C# 7.1 and .NET Core 2.0 – Modern Cross-Platform Development, Third Edition, is a practical guide to creating powerful cross-platform applications with C# 7.1 and .NET Core 2.0. It gives readers of any experience level a solid foundation in C# and .NET. The first part of the book runs you through the basics of C#, as well as debugging functions and object-oriented programming, before taking a quick tour through the latest features of C# 7.1 such as default literals, tuples, inferred tuple names, pattern matching, out variables, and more. After quickly taking you through C# and how .NET works, this book dives into the .NET Standard 2.0 class libraries, covering topics such as packaging and deploying your own libraries, and using common libraries for working with collections, performance, monitoring, serialization, files, databases, and encryption. The final section of the book demonstrates the major types of application that you can build and deploy cross-device and cross-platform. In this section, you'll learn about websites, web applications, web services, Universal Windows Platform (UWP) apps, and mobile apps. 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.

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

Exercise 10.1 – Test your knowledge

Answer the following questions:

  1. Of the encryption algorithms provided by .NET, which is the best choice for symmetric encryption?
  2. Of the encryption algorithms provided by .NET, which is the best choice for asymmetric encryption?
  3. What is a rainbow attack?
  4. For encryption algorithms, is it better to have a larger or smaller block size?
  5. What is a hash?
  6. What is a signature?
  7. What is the difference between symmetric and asymmetric encryption?
  8. What does RSA stand for?
  9. Why should passwords be salted before being stored?
  10. SHA1 is a hashing algorithm designed by the United States National Security Agency. Why should you never use it?
