You are probably hitting the following : https://github.com/aspnet/Mvc/issues/4692

Mainly take a look at the comment: https://github.com/aspnet/Mvc/issues/4692#issuecomment-223671462

Summary: You can create a Resource filter in MVC to workaround the issue:

public class CultureSettingResourceFilter : IResourceFilter, IOrderedFilter
{
    public int Order
    {
        get
        {
            return int.MinValue;
        }
    }

    public void OnResourceExecuted(ResourceExecutedContext context)
    {
        // By this time the response would already have been started, so do not try to modify the response
    }

    public void OnResourceExecuting(ResourceExecutingContext context)
    {
        var culture = httpContext.GetRouteValue("your-culture-key-name")?.ToString();
        // set your culture here
        CultureInfo.CurrentCulture = culture;
        CultureInfo.CurrentUICulture = culture;
    }
}

services.AddMvc(o =>
{
    o.Filters.Add(new CultureSettingResourceFilter());
});

Answer 2

I experimented with i18n and I got my translations to work when supported cultures matched with the cultures in resource file names

var supportedCultures = new List<CultureInfo>{
     new CultureInfo("en-US"),
     new CultureInfo("sl-SI"),
     new CultureInfo("de-DE"),
     new CultureInfo("hr-HR")
  };

Change your resource file names from

Resources/Views/ControllerName/ViewName.sl.resx

to specific language culture

Resources/Views/ControllerName/ViewName.sl-SI.resx

Edit on @Siim Haas.
It's works good.
In my case: I using the LanguageViewLocationExpanderFormat.SubFolder

At ConfigureServices(IServiceCollection services)

public void ConfigureServices(IServiceCollection services)
{
    services.AddLocalization(opts => { opts.ResourcesPath = "Resources"; });

    services.AddMvc()
        .AddViewLocalization(
            Microsoft.AspNetCore.Mvc.Razor.LanguageViewLocationExpanderFormat.SubFolder,
            opts => { opts.ResourcesPath = "Resources"; }
        )
        .AddDataAnnotationsLocalization();

    services.Configure<RequestLocalizationOptions>(opts =>
    {
        var supportedCultures = new[]
        {
            new CultureInfo("en-AU"),
            new CultureInfo("en-GB"),
            new CultureInfo("en-US"),
            new CultureInfo("en"),
            new CultureInfo("zh-cn"),
            new CultureInfo("zh"),
        };
        opts.DefaultRequestCulture = new Microsoft.AspNetCore.Localization.RequestCulture("en-US");
        opts.SupportedCultures = supportedCultures;
        opts.SupportedUICultures = supportedCultures;
    });
}

At Configure (IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    app.UseRequestLocalization();

    app.UseMvc(routes =>
    {
        routes.MapRoute(name: "default", template: "{controller=Home}/{action=Index}");
    });
}

My Resources stucts Like:

{Your Project}/Resources/Views/{your controller}/ViewName.en-us.resx
