Environment:
Win10
Visual Studio 2022 Preview lastest revision all updates installed

Attached you find a screenshot what happens when i debug the application
on an android target (works ok)
and a screenshot from the same workstation targetting
the macbook´s simulator.
Have updated Xamarin IOS to the latest version
as was suggested by the macbooks´s visual studio

Problem is clear to see i dont get any country names only the 3letter or 2letter code.

Sample code:

var regions = CultureInfo.GetCultures (CultureTypes.SpecificCultures)
	.Select (culture => new RegionInfo (culture.Name))
	.OrderBy (v => v.ThreeLetterISORegionName);
foreach (var r in regions) {
	Console.WriteLine ($"{r.ThreeLetterISORegionName} {r.NativeName} {r.Name} {r.EnglishName} {r.DisplayName}");
}

With iOS (both simulator and device) and Mac Catalyst, I get this:

 001 001 001 001
 150 150 150 150
 419 419 419 419
ABW AW AW AW AW
AIA AI AI AI AI
ALA AX AX AX AX
AND AD AD AD AD
ARE AE AE AE AE
ASM AS AS AS AS
ATG AG AG AG AG
AUS AU AU AU AU
AUT AT AT AT AT
...

on macOS, I get:

 العالم 001 world العالم
 world 001 world world
 Europe 150 Europe Europe
 Mondo 001 world Mondo
 América del Norte 003 North America América del Norte
 Latinoamérica 419 Latin America Latinoamérica
 Mundo 001 world Mundo

...

Looks like it could be a difference between Mono and CoreCLR, so I'm moving to dotnet/runtime.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

IIRC It is a difference between how the ICU data are trimmed on mobile and desktop (where it comes from untrimmed system data, usually). It is possible to switch to a different ICU data file through _GlobalizationDataFile .csproj property but I don't think .NET ships an untrimmed one.

[steveisok]

Yeah, we trimmed a great deal with WASM initially and carried it forward into iOS.

@rolfbjarne we could explore shipping an uncompressed data file that would need to be opted into. Thoughts?

That's one option, which was to some extent discussed at dotnet/designs#225. Other option is augmenting with system data through the iOS APIs (likely NSLocale localizedStringForLocaleIdentifier in this case).
