Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “By calling ThreadPool.SetMaxThreads, you can change the maximum values for workerThreads and completionPortThreads.”

A block of code is set as follows:

public async Task PerformCalculations()

{

    _runningTotal = 3;

    await MultiplyValue().ContinueWith(async (Task) => {

        await AddValue();

        });

    Console.WriteLine($”Running total is {_runningTotal}”);

}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

    private async Task MultiplyValue()

    {

        await Task.Delay(100);

        var currentTotal = Interlocked.Read(ref 

            _runningTotal);

        Interlocked.Exchange(ref _runningTotal, 

            currentTotal * 10);

    }

}

Any command-line input or output is written as follows:

$ mkdir css
$ cd css

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Let’s look at a quick example of how to implement this in our CancellationPatterns project.”
