Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "To add a friendly name, we can use the HubName attribute."

A block of code is set as follows:

    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR();
        }
    }

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 class Startup
    {
        public void Configuration(IAppBuilder app)
        {
 app.MapSignalR();
        }
    }

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

signalr.exe ghp

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Clicking on the Ok button creates a new file."
