Quick Info displays the complete code declaration and help information for any code construct. You invoke it by hovering the mouse pointer over an identifier; a pop-up box displays the information available for that identifier.
Figure 7.16 shows Quick Info being displayed for the
Console.WriteLine function. You are provided with the declaration syntax for the member and a brief description of the member. The description that shows up in the Quick Info window also works for code that you write. If you have a code comment associated with a member, IntelliSense parses the comment and uses it to display the description information.
