مجددا یک Resources file را با نام Strings.fa.resx و یکی دیگر را با نام Strings.en.resx اضافه کنید. برای درک بهتر وضعیت نهایی، پروژه XamApp را Clone/Pull کنید و آن را بررسی کنید.

در فایل Strings.resx یک ردیف جدید اضافه کنید که Name آن برابر با HelloWorld باشد و Value آن خالی است. این نام، در کد نویسی ما استفاده می‌شود و مثلا نباید شامل Space، علامت ! و ... باشد. در فایل Strings.fa.resx یک ردیف جدید اضافه کنید که Name آن برابر با همان HelloWorld باشد و Value آن برابر با سلام دنیا! در نهایت در فایل Strings.en.resx یک ردیف جدید را اضافه کنید که Name آن HelloWorld بوده و Value آن ! Hello world باشد.

سپس در فایل App.xaml.cs می‌توانید قبل از اولین NavigationService.NavigateAsync، از کد زیر را استفاده کنید:

 
Strings.Culture = CultureInfo.CurrentUICulture = new CultureInfo("en"); // or new CultureInfo("fa"); 
 

برای نمایش پیام در View Model با استفاده از IUserDialogs نیز می‌توانید به شکل زیر عمل کنید:

await UserDialogs.AlertAsync(message: Strings.HelloWorld);

در صورتیکه بخواهید پارامتری را در string‌های چند زبانه خود داشته باشید نیز می‌توانید به شکل زیر عمل کنید:
