Hello,

When I resize the app by grabbing lower edge, it just crashes. It doesn't crash all the time and it crashes occasionally. Also, when I resize with windows button, max/restore, it never crashed.

When it happens, it doesn't break at all even in debug mode and Exception Setting 'Access violation' is checked to break.

How can I debug this and prevent this? Is it from Windows bug? Or is it caused by app's code?

Based on your words, you could not reproduce it every time, right? If you could not reproduce it, I'd suggest you use the Application.UnhandledException Event to get more exception information about the crash. Next is to try to narrow down the scope of the issue. You could reduce the amount of the controls of your layout to check which control leads the issue.

Hello, thank you for your response.
I use UnhandledException, but it doesn't hit it.
The Win32 Access violation error occurs in Windows level, lower level, without communicating .NET framework of uwp, I guess.
This is why I don't know how to narrow down the issue.

Hello,

Just for others FYI, I solved the issue.
First of all, the code causing the issue was forever loop by recursive method bug.
It's nothing to do with Windows Resize directly. Window resize just created the situation triggering the bug and crash.

However, there is no way to find the clue with Visual studio because it just crash with any exception.
So, I commented out code line by line, and put log line by line find where it cause the issue, and identified the recursive method with a bug.

Recursive method with a bug can cause Access violation crash.

I hope it helps.

Thank you,
