I'm using My.Settings in my VB.NET application and when we run multiple instances rarely it's giving a ConfigurationErrorsException because the settings file locked by another instance.
Is there anyway to fix this?
This is happening during the OnShutdown process, also I'm not quite sure how can I catch that exception and handle it.
Only thing I can think of is disabling onshutdown save and manually save it during the shutdown with extra retry + locking + exception handling.
