ASP.Net Core: asp-action tag not working

Question

I have this simple anchor tag.

<a asp-area="Admin" asp-action="Create" asp-controller="Users" class="btn btn-default">Create</a>

The code structure is as follows.

The markup that is generated is as follows

<a class="btn btn-default" href="/Admin/Users">Create</a>

It is missing the action (create) but the rest of the tags seem to be working fine.

Routing setup is as follows

app.UseMvc(
    routes =>
        {
            routes.MapRoute(name: "default", template: "{controller=Home}/{action=Index}/{id?}");
            routes.MapRoute(
                name: "areaRoute",
                template: "{area:exists}/controller=Admin/{action=Index}/{id?}");
        });

Answer 1

The solution of this problem is to copy ~/Views/_ViewImports.cshtml to ~/AreaName/Views/_ViewImports.cshtml

This is because the Tag helper is made available because of @addTagHelper that is available in the _ViewImports.cshtml page.

Once you have done this, your Tag helper intellisense works as well as your Tag Helper code works!

Hope this helps. Thanks

Order matters... put the area route above that of the default.

          routes.MapRoute(
                name: "adminDefault",
                template: "{area:exists}/{controller=Home}/{action=Index}/{id?}");

           //catchall
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
