It looks like it uses one handler although the logger rotates the actual log files. I think that I would need to shut down the logger before or at the beginning of the uninstall step, but as the "uninstall application" is run from the admin app, it would be a bit tricky to implement the shutdown for a specific application in the admin application code. If there was an app.shutdown() method maybe....
For the moment I am first shutting down the application pool in IIS and then deleting the app but I would prefer a coded solution. We son't delete applications aften, so the work-around is acceptable for the moment. On Tuesday, October 27, 2020 at 4:23:09 AM UTC+1 [email protected] wrote: > Ah, i see.
