It is important to understand that Prism is not considered to provide any sort of logger out of the box. The
ILoggerFacade interface is provided as a legacy interface and does provide some debug output primarily for Prism.WPF apps, and is not really used by Prism.Forms. There are however several logging implementations provided as a Plugin for Prism which work with any Prism application.
