Error in InitializeComponent() System.IO.FileNotFoundException: '' When starting an application

[andersondamasio]

Description

Hello, since the first version of .NET Maui, we have had a problem that occurs when starting an application.

The error only occurs when "Common Language Runtime Exception" is turned on.

Common Language Runtime Exception is used a lot so that we can visualize exceptions that occur in the application, which is very important.

What bothers me the most is that this error still occurs in the .Net 9 version of Maui, making me wonder why there has not yet been a fix for such a visible point.

Steps to Reproduce

1. Create a File > New .NET MAUI App
2. "Common Language Runtime Exception" is turned on
3. And you will see the error when starting on an Android device

This issue has been verified using Visual Studio 17.13.0 Preview 2.1 (9.0.21 & 9.0.14 & 8.0.100). Can repro this issue on Android device, but Android emulator works fine.

I believe enabling that check box tells VS to break on everything, even when the code handles it. I would think that this is happening because we sometimes have to ask the OS for something, and the OS does not provide a way to list all the things. Exceptions can be used to control code flow.

I would need some more info on the exception details, such as a stack trace.

But, having an exception does not mean something is broken, it just means the code was using exceptions to do something. Sometimes it is bad, sometimes it is a feature.
