How to force WPF application to look for language specific resources?

I try to set the WPF application to display spoecified language, such as fr-FR, fr-CA and en-US.

However, No matter how I tried, it always displays in English. Here are what I tried:

MyApp.Resources.JobView.Culture = new CultureInfo("fr-FR");

System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("fr-FR");
System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("fr-FR");
 MyApp.Resources.JobView.Culture = new System.Globalization.CultureInfo("fr-FR");

The culture is set to fr-FR. But when I called:
            System.Resources.ResourceSet r =            MyApp.Resources.JobView.ResourceManager.GetResourceSet(new System.Globalization.CultureInfo("fr-FR"), false, false);

it returns English version.

On the window, it always display in en-US. I have double checked the bin\debug\en-US, fr-Ca and fr-FR. I can find the resource files there.

Anyone may help me ?

Thanks a lot.

Provide second parameter as true:

MyApp.Resources.JobView.ResourceManager.GetResourceSet(new System.Globalization.CultureInfo("fr-FR"), true, false);
