Differences in displaying currency

While playing around with formatting a string with a currency value, I noticed a difference in how WPF displays it.

When formatting a decimal value in XAML, WPF displays it as 5,99 €.

<TextBlock Text="{Binding Total, StringFormat={}{0:C}}"/>
return 5.99m;

When I format in code behind, it displays it as € 5,99.

<TextBlock Text="{Binding TotalString}"/>
return string.Format("{0:C}", 5.99m);

Is this a bug?

I got Windows 10, targeting .NET version is 4.5.2.

When setting the StringFormat of a Binding, WPF does not use CultureInfo.CurrentCulture, but just en-US by default, or the value you specify by setting the element's (or its parent's) Language property. See this question for more details.

On the other hand, string.Format does use CultureInfo.CurrentCulture. And how that exactly behaves with regard to formatting currencies is configurable by the user.

For example the currency pattern is controlled by the registry value HKEY_CURRENT_USER\Control Panel\International\iCurrency and can be set in the Control Panel (sorry it's German):

enter image description here

So you might just change that setting to achieve the formatting behaviour you get from StringFormat.
