Setting CurrentCulture AND CurrentUICulture in WPF

Question

first off, I'm aware of the general solution to the WPF culture problem: Setting Culture (en-IN) Globally in WPF App

My question is as follows: I have an IValueConverter for decimal numbers and dates and for them I get the correct CultureInfo in the interface call

object Convert(object value, Type targetType, object parameter, CultureInfo culture)

However I also want to convert an Enum value into a UI text. But for this I need CurrentUICulture and not CurrentCulture. Of course I could use Thread.CurrentThread.CurrentUICulture or CultureInfo.CurrentUICulture directly and just ignore the CultureInfo.

But that doesn't feel like proper usage of the interface.

You can directly set `ConverterCulture` in Binding – Pavel Anikhouski Oct 09 '19 at 12:22 — Pavel Anikhouski, Oct 09 '19 at 12:22

It is. An implementation of the IValueConverter interface is supposed to convert values and hence doesn't care about any UICulture.

So getting the CurrentUICulture from a source external to the converter is actually a proper use. The CurrentUICulture is not passed to the Convert method.
