Using Fallback in LocalizationProvider

if (value is null && FallbackCulture != null) resourceManager.GetString(name, FallbackCulture);

This looks like a bug, shouldn't the result be assigned to value?

Thanks for the finding. Looks like the case is not covered by a unit tests.
Would be great if you found the time for PR to fix.
