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.

Chapter 12 – Improving Performance and Scalability with Multitasking


  1. By convention, what suffix should be applied to a method that returns a Task or a Task<T>?

    Async, for example, OpenAsync for a method named Open.

  2. To use the await keyword inside a method, which keyword must be applied to the method declaration?

    The async keyword must be applied to the method declaration.

  3. How do you create a child task?

    Call the Task.Factory.StartNew method with the TaskCreationOptions.AttachToParent option to create a child task.

  4. Why should you avoid the lock keyword?

    The lock keyword does not allow you to specify a timeout; this can cause deadlocks. Use Monitor.Enter with a TimeSpan and Monitor.Exit instead.

  5. When should you use the Interlocked class?

    If you have integers and floats that are shared between multiple threads, you should use the Interlocked class.
