Exception in DataContextChanged event

If there is an exception in the DataContextChanged event, the exception will stop displaying the MainPage, but the app is still running.
The same behavior when an exception is thrown in the DataContextChanged event of controls on the MainPage.
The exception can't be catched when adding UnhandledException += OnUnhandledException; in the App.cs

Added a small blank UWP app where an exception is thrown in the DataContextChanged of the MainPage.

@RousselleHolger-4707 I have reproduced the problem as you mentioned by using your sample. The OnUnhandledException event handler isn’t called when an exception is throw in DataContextChanged event handler. I need to consult other engineers. There may be some delays.
