@ghost1372

@ghost1372 can you reproduce this problem?

@NaBian

@NaBian
I tried this over and over again, but nothing happened.
anyway I will do this again

@DineshSolanki Please upload your example. It may be related to other code in your project

@NaBian

@NaBian @ghost1372 sorry, I forgot to follow up, I noticed that after removing Notification.Show() from my code, the exception disappeared somehow.I think that should be the culprit. As my app was not in version control at that time, I don't have the old code. Just before the messageBox, I used to show the notification.see if it helps, else I'll also try to reproduce again.

I tried showing notification again, and it was still working, tried many times, couldn't reproduce, don't know what caused it. We should close this issue for now.

Hey, sorry to bother again but while updating the same program today, The exception reappeared multiple times.
It's happening with the message as well as growinfo -
here's the stackTrace -

and here's the method where it happens -

            if (Directory.Exists(SelectedFolder))
            {
                //TODO: Replace with DialogService if efficient.
                if (MessageBox.Ask("Are you sure you want to delete all Icons?", "Confirm Icon Deletion") ==
                    System.Windows.MessageBoxResult.OK)
                {
                    Util.DeleteIconsFromPath(SelectedFolder);
                }
            }
            else
            {
                MessageBox.Error("Directory is Empty", "Empty Directory");
            }
        }

@DineshSolanki

@DineshSolanki Please copy Method DeleteIconsFromPath codes here

Is the problem still there? I could not recreate the problem

@ghost1372

@ghost1372 its so random, I'm not sure what cause it or make it go away,

I'll close the issue as I haven't encountered it yet again
