Conventions

In this book, you will find a number of text styles 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: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

public async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> argument) 
        { 
            var message = await argument; 
            await context.PostAsync("Hello World: " + message.Text); 
            context.Wait(MessageReceivedAsync); 
        } 

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

Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Force -Scope  
CurrentUser

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Update all VS extensions to their latest versions by navigating to Tools | Extensions and Updates | Updates."
