My current WorkTime@WP8 Windows Phone 8 should support different languages. This is a easy task for every .NET developer – Resource files are the correct answer. But what doing with the title of the app and the title of the live tiles? These Ressouces are part of the WMAppManifest.xml file, so we cannot use the normal Resource files.
A C++ Dll project with a string table and referring the title with Title="@Sdx.WorkTime.WP8.AppResLib.dll,-100"
in the WMAppManifest.xml
(my first C++ project since 8 years)
To localize the app title, you must create the mentioned resource-only DLL, as well as separate Multilingual User Interface (MUI) files for each display language that your app targets (see screenshot).
After I have done this painful steps, it works great!
