I can save files in Android with Xamarin.Forms so:
public void SaveText (string filename, string text) {
var documentsPath = Environment.GetFolderPath (Environment.SpecialFolder.Personal);
var filePath = Path.Combine (documentsPath, filename);
System.IO.File.WriteAllText (filePath, text);
}
How can I do it in Tizen with Xamarin.Forms?

Thanks.
