Default culture in routes?

[mdmoura]

I am using the following configuration:

  services
    .AddMvc(x => { x.Filters.Add(new MiddlewareFilterAttribute(typeof(LocalizationPipeline))); })
    .AddTypedRouting()
.AddRouteLocalization(x => {

      x.UseCulture("pt")
        .WhereController(nameof(HomeController))
        .WhereAction(nameof(HomeController.Index))
        .TranslateAction("");       

    x.UseCulture("pt")
        .WhereController(nameof(AboutController))
        .WhereAction(nameof(AboutController.Index))
        .TranslateAction("quem-somos"); 

    })          
    .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
    .AddDataAnnotationsLocalization();    

    services.AddSingleton(x => {
        RequestLocalizationOptions requestLocalizationOptions = new RequestLocalizationOptions() {        
           DefaultRequestCulture = new RequestCulture("en"),
           SupportedCultures = new[] { new CultureInfo("en"), new CultureInfo("pt") },
           SupportedUICultures = new[] { new CultureInfo("en"), new CultureInfo("pt") },
        };
        requestLocalizationOptions.RequestCultureProviders.Insert(0, new RouteDataRequestCultureProvider());
        return requestLocalizationOptions;
  });

}

So I get the following Routes:

Home
  EN: /
  PT: /pt

About
  EN: /about
  PT: /pt/quem-somos

Should the website also work with:

Home
  EN: /en

About
  EN: /en/about

English version would have /en in the route ... The default version with no culture in the route would also be english since is the default one.

What is the best approach for this?

What about WhereUntranslated and AddDefaultTranslation?

.AddRouteLocalization(x =>
{
    x.UseCulture("en")
        .WhereUntranslated()
        .AddDefaultTranslation();

    x.UseCulture("pt")
        .WhereController(nameof(HomeController))
        .WhereAction(nameof(HomeController.Index))
        .TranslateAction("");

    x.UseCulture("pt")
        .WhereController(nameof(AboutController))
        .WhereAction(nameof(AboutController.Index))
        .TranslateAction("quem-somos");
})

Does this satisfy your needs?
