hi sir,

how to edit this code ->

// add culture route segment for controllers e.g. /en/Home/Index
    .AddMvcOptions(ops => ops.Conventions.Insert(0, new RouteTemplateModelConventionMvc()))

because make this error:

 An unhandled exception occurred while processing the request.

@Malkawi1

Check if you have a culture paramter setup already made in page route, if so remove it because the code below is already adding the culture parameter to all routes.

.AddMvcOptions(ops => ops.Conventions.Insert(0, new RouteTemplateModelConventionMvc()))

Or delete the above line if you want to use your own culture parameter setup.

@LazZiya

After remove this line -> .AddMvcOptions(ops => ops.Conventions.Insert(0, new RouteTemplateModelConventionMvc()))

when choosing language -> error

This localhost page can’t be foundNo webpage was found for the web address: https://localhost:44349/ar HTTP ERROR 404

[LazZiya]

After removing that line you need to manually add the culture parameter to the routes {culture}

[Malkawi1]

add to this line -> like this <language-nav cookie-handler-url="@Url.Action("SetCultureCookie", "Home", "{culture}",new { area="", cltr="{0}", returnUrl="{1}", culture=CultureInfo.CurrentCulture.Name })">

[LazZiya]

So if it is ok now we can close this issue, is it?

@LazZiya

sir, when using the package LazZiya.ExpressLocalization

after running the code shown in this route -> https://localhost:44349/en/Identity/Account/Login/?ReturnUrl=/en/

so, this route is wrong and this true route -> https://localhost:44349/Account/Login/?culture=en

so how to edit my route to be true

note I'm using .net 6

and this is my code in program.cs

CultureInfo us = new CultureInfo("en-US"); var cultures = new CultureInfo[] { new CultureInfo("en"), new CultureInfo("ar") { DateTimeFormat = us.DateTimeFormat } };

// Add services to the container. builder.Services.AddControllersWithViews()

.AddExpressLocalization<LocSource>(
        ops =>
        {
            ops.ResourcesPath = "LocalizationResources";
            ops.RequestLocalizationOptions = o =>
            {
                o.SupportedCultures = cultures;
                o.SupportedUICultures = cultures;
                o.DefaultRequestCulture = new RequestCulture("en");
            };

        });

app.UseRequestLocalization();

[LazZiya]

Well, I see you are using LazZiya.ExpressLocalization, I recommend you switch to XLocalizer, it is much better in terms of flexibility and provides better support for newer frameworks.

[Malkawi1]

After removing that line you need to manually add the culture parameter to the routes {culture}

@LazZiya

how invested this lin by parameter {culture}
.AddMvcOptions(ops => ops.Conventions.Insert(0, new RouteTemplateModelConventionMvc()))

please tell me step by step

[LazZiya]

With reference to XLocalizer version of RouteTemplateModelConventionMvc(), it adds a route parameter named {culture?} to all routes in the app, so you don't have to add it manually to each route in the routing table.

// e.g.:
[controller]/[action] --> {culture?}/[controller]/[action]

[LazZiya]

Hi @Malkawi1 ,

Do you still need support with this issue?
