❔ Execute code on WPF program close
Hi, is there a way I can execute some code every single time the application closes. Either if it crashes, is closed manually, the computer restarts, or closed thru task manager or whatever?

For WPF
BLike run it after it exits / crashes? i don't think so? You might have to write your own custom window service to monitor that.
Sif it crashes you could have a global exception handler
Sis its closed normally just handle the closed event
Sbut if the process is killed im not sure you can do that
Swhy do you even care about that
Obecause my program creates a proxy
Oif you don’t shut it off correctly you don’t have any internet connection after the program closes
O^
Sit would be the users fault that they killed the process
Syou shouldnt worry about that
Owell
Ostill
Oi have to provide support if they suddenly don’t have internet anymore so its much easier to just do it programatically
Sit doesnt seem to be possible
Si guess you could make it a windows service?

Ookay
Ohow do I do that? And what is it
OInsteaf of making a windows service, I'm thinking of the program running a another small program thats hidden in the background, which checks periodically if the main program is still running, and if not, if it has shut down correctly, if so, the background program will shut down
JI'd say making a Windows Service actually doesn't sound to bad
Jessentially, you want a small program running in the background that can detect when your application opens and closes, and swap the proxy setup as needed whenever that happens

Obut I haven't worked with windows services before, and it seems like the user has to do smth when looking at the documentation?
JI'm also gonna suggest that whatever you're doing, there's probably a more effective way to do it, that doesn't involve screwing with network config for the whole machine
OLearn how to create a Windows Service using the BackgroundService in .NET.
Othere isn't really
Jhow so?
Oit has to monitor internet traffic so it uses a proxy at 127.0.0.1 to view it
Jyou're trying to monitor all traffic for the whole machine?
Oyep
Jsounding more suspicious by the moment
Olol
Oits nothing sus
Oi'm only looking for some specific requests
Oanyways, it doesn't really matter, is there some docs on how to make a windows service and run it from c#?, idk how they work, do I have to manually start and stop them or?
Jthey can be automatic
Obut there isn't really a reason to have it running when my program isn't running
Jsure there is
O?
Oit should only start when the program is opened, and close when the proxy is shut off
Jthat's how you achieve the behavior you want
Obut for windows services, it seems like the user has to do a ton of stuff to make it run
Jnot really
Jjust has to install it
Jwhich requires admin privileges
Othe program already has admin privileges
Jwhich you need anyway to mess with network config
Oyea
Obut can I start the install from the program, or the user has to manually click a installer
J¯\_(ツ)_/¯
