ASP.NET Core Pitfalls - Localization with Shared Resources

When localizing a web application using resources, there are two common ways:

• Using a resource per Razor view or page
• Using shared resources, e.g., not bound to a specific view or page

By default, ASP.NET Core’s localization expects resource files(.resx) to be located inside a Resources folder on the root of the web application. When using shared resources, we often create a dummy class (say, SharedResources) to which we can associate resources that are not associated with a specific view or page, for example, resources used in the page layout, so, we may be tempted to place this class inside this Resources folder. It turns out, however, that that won’t work: even if you change the namespace of this class to be the root assembly namespace (usually the web application’s name), the satellite resource assembly will not be generated properly. The solution is to place the dummy class at the root of the application (for example) and leave the resource files inside the Resources fThe code goes like this, in ConfigureServices:

services.AddMvc()
    .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix);

And in Configure:

var supportedCultures = new[] { "en", "pt" };

var localizationOptions = new RequestLocalizationOptions() { ApplyCurrentCultureToResponseHeaders = true } .SetDefaultCulture(supportedCultures[0]) .AddSupportedCultures(supportedCultures) .AddSupportedUICultures(supportedCultures); app.UseRequestLocalization(localizationOptions);

Finally, to use in a Razor view or page:

@inject IHtmlLocalizer<SharedResources> Localizer

<h1>@Localizer["Hello"]</h1>

Worth saying that this happens in ASP.NET Core 3.1 as well as in ASP.NET Core 5.

• Kindly help me!!!
  This code is not going on action method of a controller. The View method is inherited from the Controller class.
  What else do you need to know?
  Cheers

• Help me!
  This code does not rely into the actions method of controller. View method is inherited from the Controller class. View method is an inheritance method of the Controller class. What more do you require to be aware of?
  Thanks
