Question: How can I localize an button in the bottom appbar. I want to write on a german device 'Neu' under the button and on an english device 'Add'.

```
<Style x:Key="AddAppBarButtonStyle" TargetType="ButtonBase" BasedOn="{StaticResource AppBarButtonStyle}">
    <Setter Property="AutomationProperties.AutomationId" Value="AddAppBarButton"/>
    <Setter Property="AutomationProperties.Name" Value="Add"/>
    <Setter Property="Content" Value="&#xE109;"/>
</Style>

```

Thanks!

Answer: 
I think you're looking to use the `Multilingual App Toolkit` for Visual Studio which allows you to change the content in your application depending on the user prefered language.

You can download it clicking this link: <http://msdn.microsoft.com/en-us/windows/apps/hh848309.aspx>

and here is an short helpful video which shows how it works: <http://www.youtube.com/watch?v=Uyts-DQbC4w>

This is the recommended method from Windows 8:

Example for a Button (C#)

1. Create a resource file: strings/de-de.resw
In the Resource file you must type this:

`desplay.Text` (first colum)  

`play the music here`(2th colum)  

 2. Then add this parameter `x:Uid` to get translation from Resource file.
