CultureInfo from RegionInfo using LINQ

Question

Need some help as this is driving me insane and I can't tell if I'm doing something stupid or not.

I'm trying to gather a list of all specific cultures and get their corresponding RegionInfo. from that list I'm attempting to get the region corresponding to a country supplied by a parameter. I'm attempting this through LINQ, as seen below;

public RegionInfo getregion(string country)
{
    RegionInfo thisregion;
    List<RegionInfo> regions = new List<RegionInfo>();
    CultureInfo[] allregions = CultureInfo.GetCultures(CultureTypes.SpecificCultures);
    regions.AddRange(allregions.Where(x => !x.IsNeutralCulture).Select(x => new RegionInfo(x.LCID)));
    thisregion = regions.FirstOrDefault(region => region.EnglishName == country);
    return thisregion;
}

This particular function keeps throwing an exception during the Select() statement, error below;

Additional information: Culture ID 4096 (0x1000) is a neutral culture; a region cannot be created from it.

The culture in question causing the issue is aa-ER. As you can see, I have filtered the list based on the IsNeutralCulture Boolean, so the net framework doesn't think this culture is neutral, yet the error says otherwise.

Am I doing something stupid?

EDIT: Interestingly, the first comment lead me to test it on a different machine, which didn't throw the error on the same culture. Looks like a machine problem.

Answer 1

OK, so as a workaround to this issue, I changed the Select statement to initialise RegionInfo for x.Name instead of x.LCID and this has worked. Don't know why the LCID was failing, but this solution will do.
