Describe the bug
The RequestLocalizationMiddleware sets the culture to default even if the RequestLocalizationOptions supports CultureInfo.InvariantCulture since version 8.
Example:
builder.Services.Configure<RequestLocalizationOptions>(options => {
var supportedCultures = new[]
{
CultureInfo.InvariantCulture,
CultureInfo.GetCultureInfo("fr"),
CultureInfo.GetCultureInfo("en"),
};
options.DefaultRequestCulture = new(supportedCultures[1]);
options.SupportedCultures = supportedCultures;
options.SupportedUICultures = supportedCultures;
options.RequestCultureProviders =
[
new DefaultRequestCultureProvider()
];
});
public class DefaultRequestCultureProvider : IRequestCultureProvider
{
public Task<ProviderCultureResult?> DetermineProviderCultureResult(HttpContext httpContext)
{
var result = new ProviderCultureResult(culture: CultureInfo.InvariantCulture.Name, uiCulture: CultureInfo.CurrentUICulture.Name);
return Task.FromResult<ProviderCultureResult?>(result);
}
}At the end, CultureInfo.CurrentCulture was always the DefaultRequestCulture instead of CultureInfo.InvariantCulture.
Note: this code worked until version 8
