InfoBar class
The InfoBar control is for displaying app-wide status messages to users that are highly visible yet non-intrusive. There are built-in Severity levels to easily indicate the type of message shown as well as the option to include your own call to action or hyperlink button. Since the InfoBar is inline with other UI content the option is there for the control to always be visible or dismissed by the user.
