The Studio has a window that allows you to view logging entries for any solution that was run in the current session. To run a solution in the Studio, see Testing a Solution in the Studio.
To display this log window, double-click on the taskbar at the bottom of the main Studio's main window, or go to the View menu > Studio Log.
All logging entries from the current session of Studio are written to a log file created in the logs directory, under the data folder. Log files are named studio-n.log. Each time you start the Studio, a new log file is created with n incremented by one.
