WPF TextBox binding to decimal respecting culture

问题

I've bound a TextBox to a Decimal. My problem ist, the Binding is using american numerical standards, using a dot for decimals separation ("1.5")

My system is german and configured to use a comma as decimals separation ("1,5").

I need the TextBox binding to show and use a comma instead of a dot to separate decimals.

How do I get the binding to respect the currently set localization/culture settings for numerical input?

Read this article. You should set default language for all framework elements:

public partial class App : Application
{
    static App()
    {
        FrameworkElement.LanguageProperty.OverrideMetadata(
            typeof(FrameworkElement),
            new FrameworkPropertyMetadata(
                XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));
    }
}
