Problem in accessing localized string in ASP.NET MVC application

Answer 1

The CurrentCulture and CurrentUICulture does not automatically change according to what the browser reports. You will need to specify that:

protected override void OnInit(EventArgs e)
{
    try
    {
        System.Threading.Thread.CurrentThread.CurrentUICulture = 
                          CultureInfo.GetCultureInfo(Request.UserLanguages[0]);
        System.Threading.Thread.CurrentThread.CurrentCulture = 
                          System.Threading.Thread.CurrentThread.CurrentUICulture;
    }
    catch (Exception ex)
    {
        // handle the exception
    }
    base.OnInit(e);
}

You should note that some of the languages that you can select ("en" for instance), will cause an exception when trying to assign it to Thread.CurrentCulture, since it does not allow what is called "neutral" cultures. In short, a neutral culture is one that identifies only a language, but not geographical region. You can read more about that in the documentation for the CultureInfo class.
