Register the downloaded assemblies in the GAC or place them in your application bin folder. Note that the first approach allows you to see the localized values both at runtime and design time, but the second approach – only at runtime.
Satellite assemblies are reusable in any other project.
In the module project, double-click the Model.DesignedDiffs.xafml file to invoke the Model Editor. Focus the root node and click Languages Manager... in the Language combo box on the Model Editor Toolbar. Add the target language in the invoked dialog and click OK. Restart Visual Studio to load localized values from the satellite assemblies and specify the application's target language in the Language combo box.
To specify an application's language, invoke the Model Editor for an application project, navigate to the Application node and set the IModelApplication.PreferredLanguage property to the required language. Refer to the Localization Basics topic for more details. If you want your application's language to match the language on the user's device (or browser language for Mobile applications), set the PreferredLanguage property to (User language).
