How to create mini dump in MAUI program?

[ss1969]

Hi ,

I want my MAUI program create mini dump with stack info only when crash. (Windows Only).

Outside main thread, It's done by "SetUnhandledExceptionFilter() -> MiniDumpWriteDump()“. It works partialy, as some exceptions cannot be caught, such as AccessViolation / StackOverflow; other exceptions are caught correctly such as NullReference.

However, within the main thread, I suspect there might be some mechanism in the MAUI framework that prevents this approach from capturing exceptions, thus preventing me from actively generating a dump. Instead, a dump file with the same name as the executable will be generated in the %LOCALAPPDATA%\CrashDumps directory. Unfortunately, I have no control over the size of this dump file, and what I want is a Minidump with a size of approximately 2MB. I wonder if there is any way to achieve this?
Then I found this: https://learn.microsoft.com/en-us/dotnet/core/diagnostics/collect-dumps-crash#types-of-mini-dumps , but it's not working due to some unknown reasons.

Env: Win11, .Net 8, VS 2022 17.10
