printf style logging for f#

Question

How do i setup a printf-style logger for f# using logging library similar to log4net. i have Log.Debug, Info, Warn, etc. functions that are similar to DebugFormat or InfoFo

I'm not familiar with log4net, but assuming you're logging to a MessageBox (like the pros do), you can do the following:

let log format = Printf.kprintf (fun msg -> System.Windows.Forms.MessageBox.Show(msg)) format

In this case, since Show takes a string, it can be shortened to:

let log format = Printf.kprintf System.Windows.Forms.MessageBox.Show format
