Reason for change
The ResourceManagerWithCultureStringLocalizer class and ResourceManagerStringLocalizer.WithCulture method were often sources of confusion for users of localization. The confusion was especially high when creating a custom IStringLocalizer implementation. This class and method give consumers the impression that an IStringLocalizer instance is expected to be "per-language, per-resource". In reality, the instance should only be "per-resource". At run time, the CultureInfo.CurrentUICulture property determines the language to be used.
Recommended action
Stop using the ResourceManagerWithCultureStringLocalizer class and the ResourceManagerStringLocalizer.WithCulture method.
