Hi Guys,

I have developed a sample MAUI App using .Net 9. But it aborted at run time without showing any result.

It built the Windows Machine version without any error.

When checked the output window, it shows this message.


The target process exited without raising a CoreCLR started event. Ensure that the target process is configured to use .NET Core. This may be expected if the target process did not run on .NET Core.

The program '[8424] ProductFinder.exe' has exited with code 3221227010 (0xc0000602) 'The process aborted due to a fail fast exception.'.


I followed this link to create the app.

https://learn.microsoft.com/en-us/dotnet/maui/get-started/first-app?pivots=devices-windows&view=net-maui-9.0&tabs=vswin

My PC is "Windows 11 Home Single Language".

I'm using Visual Studio 2022 - Version 17.13.6

Also my app is set to .Net 9 as the target .net runtime.

and "target windows framework" and "minimum target windows framework" is set as 10.0.26100.0

What can be the reason of this error message?

Please advise.

Thanks in advance.
