No names for culture region

[whann0205]

Description

You get instead of names the 2 letter iso code.
Same Code works under Android and used to work in older maui
versions.
Have already tried to contact dotnet/runtime and
Xamarin IOS but didnt work out eg. hep me fix that one.
That happens if you use the ios simulator on a mac m1
device.
The application uses the netmaui blazor variant,
in case if that could be relevant.

Steps to Reproduce

Create a function as shown below somewhere and call it:

var regions = CultureInfo.GetCultures (CultureTypes.SpecificCultures)
	.Select (culture => new RegionInfo (culture.Name))
	.OrderBy (v => v.ThreeLetterISORegionName);
foreach (var r in regions) {
	Application.Current.MainPage.DisplayAlert ('Showme",$"{r.ThreeLetterISORegionName} {r.NativeName} {r.Name} {r.EnglishName} {r.DisplayName}","OK");
}

I see you mention "6.0 Release Candidate 3" as a version, is this correct? If so, why are you using an older version? Would you be able to try the latest version and see if it still happens there?

I have installed the lastest visual studio 2022 on both machines
and the .net maui workload. Regarding the version i only selected the last entry
of the list. I can confirm for you whatever you need to know about the machine if
you tell how or what command i should run.

@whann0205 thanks for checking on the latest version. Does this issue occur only on iOS devices? If so, it might be an issue specifically with Xamarin.iOS. @rolfbjarne - checking with you if maybe this should move to https://github.com/xamarin/xamarin-macios/ ?

hi elilon,
Yes its an issue only occurs in the ios emulator, cannot test a physcial iphone since net maui does
currenlty not support it AFAIK. The Ios emulator is running on my m1 macbook.

i have already done that with rolf
xamarin/xamarin-macios#15159
and after an interlude with dotnet/runtime team he mention to try it here..

[rolfbjarne]

@Eilon so the actual bug is in dotnet/runtime. I suggested a workaround here: xamarin/xamarin-macios#15159 (comment), but apparently that's not working because the reporter is using Blazor (xamarin/xamarin-macios#15159 (comment)). So the question is if it's possible to work around this using Blazor (and if so, how) - I have no idea how to make this code work with Blazor: xamarin/xamarin-macios#15159 (comment)

[whann0205]

In fact its net.maui blazor and the reporter is me :-).
I am pretty sure that this problem is existent in the standard net.maui without blazor as well,
although not tested yet

[Eilon]

It does look like a dup of dotnet/runtime#70028. I highly doubt this is Blazor-specific because in .NET MAUI Blazor apps, all the C#/.NET code runs in whatever the native runtime is on that devices. With Blazor it just renders some UI as HTML, but the app code is regular .NET code.

So, let's use dotnet/runtime#70028 to track this.

Well i posted here since the guys at dotnet/runtime - please read their posts - seems to
not understand the topic in detail. In addition i fear they do not want to fix that one and wait
for .net 7. So i would highly appreciate when you post there as well to clear things up.
