Could you please provide more details? because I don't have this issue in my machine.

It breaks on NonExistentProperty in a binding. Got the same thing here :)

@niels9001 @Jay-o-Way
I recloned the project and ran the main branch, but I didn't encounter any issues. I'm unsure about the next steps—should we simply remove the "FallbackValue and TargetNullValue" example?

Interesting. I wonder what could lead to this difference...

@marcelwgn
Any pointer on how to resolve this?

The app isnt crashing for me either. @Jay-o-Way @niels9001 do you hit the unhandled exception block in App.xaml.g.cs or how does this issue surface for you?

file App.xaml.cs to be exact

I guess this is making the difference:

I understand that this is an example of binding failure, but it doesn't necessarily mean that the actual code should have it, right?🤔

I’m curious about the purpose of the DebugSetting_BindingFailed method. Additionally, what would happen if the Continue button were clicked after the break?
