ASP.Net Core 3.1:

I can confirm that this is working if it's configured properly (see the second code block)

CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;

In your startup class add this to the Configure method:

            IList supportedCultures = new List
            {
                new CultureInfo("en-US"), //English US
                new CultureInfo("ar-SY"), //Arabic SY
            };
            var localizationOptions = new RequestLocalizationOptions
            {
                DefaultRequestCulture = new RequestCulture("en-US"), //English US will be the default culture (for new visitors)
                SupportedCultures = supportedCultures,
                SupportedUICultures = supportedCultures
            };

            app.UseRequestLocalization(localizationOptions);

Then the user can change the culture by calling this action:

        [HttpPost]
        [ValidateAntiForgeryToken]
        public IActionResult SetCulture(string culture, string returnUrl)
        {
            HttpContext.Response.Cookies.Append(
                CookieRequestCultureProvider.DefaultCookieName,
                CookieRequestCultureProvider.MakeCookieValue(new RequestCulture(culture)),
                new CookieOptions { Path = Url.Content("~/") });

            if (!string.IsNullOrEmpty(returnUrl) && Url.IsLocalUrl(returnUrl))
            {
                return LocalRedirect(returnUrl);
            }

            return RedirectToAction("Index", "Home");
        }
