System-supplied error message missing when PublishSingleFile & SelfContained

[JJLovesLife]

Console.WriteLine(new FileNotFoundException(null, "file.txt").Message);

When run in normal build, this will show Could not load file or assembly 'file.txt'. The system cannot find the file specified..
The Message returns system-supplied error message because null is pass to constructor.
However, if you publish with dotnet publish -p:PublishSingleFile=true -p:SelfContained=true, then run the published exe file. You got empty string, without enriched exception message from runtime resource.

Seems it is caused by the mscorrc.dll missing when self-contained & single bundle. Is this expected?

It's not about mscorrc.dll. Managed resources are bundled with managed assembly.

I can't reproduce this with SDK 9.0.102.

Sorry I mistyped, the publish command should be -p:SelfContained=true. I got the issue with sdk 9.0.200-preview.0.25057.12 and able to reproduce with 9.0.102 too.
