Why cant I use tag helpers to generate links to my Area?

Question

I have a Area route setup in my .net core 3.1 web app:

Startup.cs / Configure():

app.UseEndpoints(endpoints =>
            {
                endpoints.MapAreaControllerRoute(name: "secure-route", areaName: "Secure", pattern: "Secure/{controller=Dashboard}/{action=index}/{id?}");
            });

The routing for this works fine, all pages under "/secure" works fine. However, when I try to add links or post a form in any of the views, the give strange urls in the format of:

https://localhost:44370/MyController/Edit?area=secure

This should be: https://localhost:44370/Secure/MyController/Edit

Any ideas whats wrong?

I have tried all matter of tag-helpers, but the problem seems to be with the routing itself. None of these work:

<form method="post" asp-controller="MyController" asp-action="Edit" asp-area="secure">
<form method="post" asp-controller="MyController" asp-action="Edit">
<button asp-controller="MyController" asp-action="EditMyEntity">Click Me</button>

According to your description, I guess you may missed addTagHelper for the area. So all the tagheler will not work well.

I suggest you could try to created a new _ViewImports.cshtml or move the default view folder's _ViewImports.cshtml into the application root path and add the taghelper codes.

@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
