How to force locale in ASP MVC?

Question

IIS

Hello!
it is necessary that the validation messages be in Russian ... registered in the webconfig:

<system.web>
    <globalization uiCulture="ru-RU" culture="ru-RU" />

and in globalajax:

protected void Application_BeginRequest()
        {
            System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("ru");
            System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("ru");
        }

but still - joxi.ru/gV2VeYZiZOXgmv how else can you force it? Hosting is kind of a bummer.
UP:
as a temporary measure made in the model:

[Required (ErrorMessage = "Обязательно для заполнения")]

Answer 1

In the controller, check the locale, if necessary - check the resources, maybe something is wrong with them.
