log4net in WPF

In questo articolo vengono fornite indicazioni / esempio su come impostare i contenuti dei files in una app di WPF, senza entrare nel dettaglio di tutti i particolari che sono accessibili direttamente dalla documentazione ufficiale (http://logging.apache.org/log4net/). Verrà pertanto fornito un esempio copy/paste/go da modificare in funzione delle specifiche esigenze…
