It would probably be stupid or a concept problem.
I have a class with a method called ShowDialog which it loads a Msgbox.
I declare a public instance in the starter service.
If I initialize it in Main, and I call the ShowDialog method it's displayed correctly.
But if I initialize it in StarterService (in Service_Start), and call Showdialog in Main, this error is triggered.
Starter code:
Main Code:
Why does it happen? Any idea? Thanks in advance
