Hi i have an asp.net core project that is based on 3.1 , however its not finding my resource when its in a shared libary it works fine in the same libary but not the shared one.

This is my startup file

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Identity.UI;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.HttpsPolicy;
using Microsoft.EntityFrameworkCore;

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using MISSystem.WebApi.Data;
using MISSystem.Dal;
using MISSystem.Models;
using MISSystem.Web.Helpers;
using MISSystem.Web.Localization;
using Microsoft.AspNetCore.Mvc.Razor;
using System.Globalization;
using Microsoft.AspNetCore.Localization;
using Microsoft.Extensions.Options;

namespace MISSystem.Web {
    public class Startup {
        public Startup(IConfiguration configuration) {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services) {
            services.AddDbContext<MISDBContext>
          (options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(
                    Configuration.GetConnectionString("DefaultConnection")));

            services.AddDefaultIdentity<ApplicationUser>()
                .AddEntityFrameworkStores<MISDBContext>().AddClaimsPrincipalFactory<MyUserClaimsPrincipalFactory>();  //<---- add this line 

             

            services.AddControllersWithViews();
            services.AddLocalization();

            services.AddRazorPages().AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
           .AddViewLocalization()
           .AddDataAnnotationsLocalization();


            services.AddLocalization(o => o.ResourcesPath = "Resources");
            services.Configure<RequestLocalizationOptions>(options => {
                var supportedCultures = new[] { new CultureInfo("en"), new CultureInfo("fr") };

                options.DefaultRequestCulture = new RequestCulture(culture: "en", uiCulture: "en");
                options.SupportedCultures = supportedCultures;
                options.SupportedUICultures = supportedCultures;
                options.RequestCultureProviders = new List<IRequestCultureProvider>
            {
                new QueryStringRequestCultureProvider(),
                new CookieRequestCultureProvider()
            };
            });

            services.AddSingleton<ISharedResource, SharedResource>();

        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env) {
            var locOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();
            app.UseRequestLocalization(locOptions.Value);
                
            if (env.IsDevelopment()) {
                app.UseDeveloperExceptionPage();
                app.UseDatabaseErrorPage();
            } else {
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }

            var supportedCultures = new[] { "en-US","en-GB", "fr" };
            var localizationOptions = new RequestLocalizationOptions().SetDefaultCulture(supportedCultures[0])
                .AddSupportedCultures(supportedCultures)
                .AddSupportedUICultures(supportedCultures);
            app.UseRequestLocalization(localizationOptions);
          

            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints => {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
                endpoints.MapRazorPages();
            });
        }
    }
}

As you see I am setting up the loclization middle ware fine I have installed the nugets for locazliation as well as some said it didnt work until that was done.

Hi roguenidb,

I have two projects

MISSystem.Web

MISSystem.Lng I set the default name space ie the root name space to be the same of MSISystem.Web

The two project namespace could not be the same.

Then,please check the following answer:

Hi roguenidb,

You just provide the startup.cs.Not sure how did you define SharedResource and what is your project structure?

Notes:No need to change the default namespace.

This is my working demo:

In your MISSystem.Lng class library:

1.Create SharedResource.cs in the root project.

public class SharedResource
{
}

2.Create Resources/SharedResource.fr.resx:

3.The project structure:

In your MISSystem.Web web application:

1.Add MISSystem.Lng reference to MISSystem.Web(right-click Dependencies which is in MISSystem.Web->Add Reference->Choose MISSystem.Lng):

2.HomeController:

using MISSystem.Lng;  //remember to add this reference

public class HomeController : Controller
{
    private readonly IStringLocalizer<SharedResource> _sharedLocalizer;

    public HomeController(IStringLocalizer<SharedResource> sharedLocalizer)
    {
        _sharedLocalizer = sharedLocalizer;
    }

    public IActionResult Index()
    {
        ViewData["Message"] = _sharedLocalizer["Hello"];
        return View();
    }
}

3.Startup.cs:

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

    services.AddRazorPages().AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
    .AddViewLocalization(options => options.ResourcesPath = "Resources")
    .AddDataAnnotationsLocalization();

    services.Configure<RequestLocalizationOptions>(options =>
    {
        var supportedCultures = new[]
        {
            new CultureInfo("en-US"),
            new CultureInfo("en-GB"),
            new CultureInfo("fr")
        };
    
        options.DefaultRequestCulture = new RequestCulture(culture: "en-GB", uiCulture: "en-GB");
        options.SupportedCultures = supportedCultures;
        options.SupportedUICultures = supportedCultures;
    });
        
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseRequestLocalization();

    app.UseHttpsRedirection();
    app.UseStaticFiles();

    app.UseRouting();

    app.UseAuthorization();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllerRoute(
            name: "default",
            pattern: "{controller=Home}/{action=Index}/{id?}");
    });
}
