首先在 Startup 的 ConfigureServices 中添加 AddLocalization 與 AddViewLocalization 以及配置 RequestLocalizationOptions （這裡假設使用英文與中文）：
public void ConfigureServices(IServiceCollection services){ services.AddLocalization(options => options.ResourcesPath = "Resources"); services.AddMvc() .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix); services.Configure<RequestLocalizationOptions>( opts => { var supportedCultures = new List<CultureInfo> { new CultureInfo("en-US"), new CultureInfo("zh-CN") }; opts.SupportedCultures = supportedCultures; opts.SupportedUICultures = supportedCultures; });}
在 Startup 的 Configure() 方法中應用 RequestLocalizationOptions ：
var requestLocalizationOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>().Value;app.UseRequestLocalization(requestLocalizationOptions);
然後在 _Layout.cshtml 視圖中通過 IViewLocalizer 介面以多語言的方式顯示頁面標題的尾碼：
@using Microsoft.AspNetCore.Mvc.Localization@inject IViewLocalizer Localizer<!DOCTYPE html><html><head> <title>@ViewData["Title"] - @Localizer["SiteTitle"]</title></head><body></body></html>
接著在 ASP.NET Core Web 項目中建立 Resources 檔案夾，在其中分別添加 Views.Shared._Layout.en-Us.resx 與 Views.Shared._Layout.zh-CN.resx 檔案， Views.Shared._Layout.resx 檔案，並添加 "SiteTitle" 所對應的語句文字：
1）Views.Shared._Layout.en-Us.resx
2）Views.Shared._Layout.zh-CN.resx
這時運行 ASP.NET Core 網站，就會根據瀏覽器的語言設定（Accept-Language header）、或者 culture 查詢參數、或者 .AspNetCore.Culture Cookie 值顯示對應語言的文字：
需要注意的地方：千萬不要添加不帶語言名稱的 Views.Shared._Layout.en-Us.resx ，不然添加代碼語言名稱的 .resx 檔案時會遇到 "Custom tool ResXFileCodeGenerator failed to produce an output for input file ... but did not log a specific error." 問。
