Hi,

I am trying to run a C++ Win32 application with XAML Island as UI Library. I am able to run on normal desktop machines such as Windows 11 but when I try to run the same application on Windows Server core machine it failed and didn't even reach our entry point -- 'wWinMain'.

I tried to check the event logs in this Server core machine using the below command. Pasting the command and adding the logs that I received. We are not able to understand what is such causing this issue, can somebody help here?

Get-EventLog -LogName Application -EntryType Error -Newest 1 | Format-List -Property *

Error Details:
Exception code: 0xc0000409

Fault offset: 0x0000000000453f9d

Faulting process id: 0x808

    Is it possible that Server Core doesn't have the full UI capabilities, and Xaml is one of the things that is missing?

    The exception code, 0xc0000409 is traditionally documented as STATUS_STACK_BUFFER_OVERRUN, but it is used as the status code for any fast process exit. It is the code that appears when a process calls __fastfail in user mode.
