In Ubuntu 23.04 I needed to modify Melkhior.runtimeconfig.json by adding
"System.Globalization.Invariant": true
to the configProperties (note - needs a comma to the previous line)
full file is below...
{
"runtimeOptions": {
"tfm": "netcoreapp3.1",
"includedFrameworks": [
{
"name": "Microsoft.NETCore.App",
"version": "3.1.11"
}
],
"configProperties":
{
"System.Runtime.TieredCompilation": false,
"System.Globalization.Invariant": true
}
}
}
works a charm - thanks
