Conventions used

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

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "An Azure Function written in C# is a static method decorate by a FunctionName attribute."

A block of code is set as follows:

public static class SimpleExample
{
    [FunctionName("QueueTrigger")]
     public static void Run(
         [QueueTrigger("inputQueue")] string inItem,
         [Queue("outputQueue")] out string outItem, 
         ILogger log)
     {
         log.LogInformation($"C# function processed: {inItem}");
     }
}

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

public static class SimpleExample
{
    [FunctionName("QueueTrigger")]
     public static void Run(
         [QueueTrigger("inputQueue")] string inItem,
         [Queue("outputQueue")] out string outItem, 
         ILogger log)
     {
         log.LogInformation($"C# function processed: {inItem}");
     }
}

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

c:>npm install -g azure-functions-core-tools

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Simply choose the menu File | New | Project."
