[Solved] Code is WRONG but no error is raised

Question

What UI frameworks do you use? Some .Net UI Frameworks indeed provide you some “Load” events, but also some happen to SILENCE all exceptions that happen during your even-handlers, “to provide better UI Experience to the end user”.

You can check easily if any exceptions are thrown in the OUTPUT panel under debugger. If you see any “First chance exception” – then here you have it, your UI Framework is “quiet one”.

Add try-catch, or add application.unhandledexception eventhandler, and just try to bear with your quiet UI..

If I recall correctly, the WPF liked to silently skip exceptions, while WinForms tended to crash instantly. But I may be wrong here.
