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, path names, dummy URLs, user input, and Twitter handles are shown as follows: "Media files with the <video> and <audio> tags as long as the file type matches expected media formats."

A block of code is set as follows:

public static class WebApiConfig
{
  public static void Register(HttpConfiguration config)
  {
    // Other configurations omitted config.EnableCors();
    config.SetCorsPolicyProviderFactory(
      new DynamicPolicyProviderFactory());
  }
}

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

PM> Install-Package Microsoft.AspNet.WebApi.Cors

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: "Clicking the Next button moves you to the next screen".
