The ASP.NET Core MVC tag helpers aren’t acting like they used to. When I write something like this:

<a asp-area="Admin" asp-controller="Home" asp-action="Index"></a>

The link redirects me to ~/Home/Index?area=Admin instead of ~/Admin/Home/Index (which can be simplified to ~/Admin).

I have decorated the controllers in that area with [Area("Admin")], the tag helpers are imported in my _ViewImports inside ~/Areas/Admin/Views folder and my routing configuration looks like this:

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");
app.MapControllerRoute(
    name: "areaRoute",
    pattern: "{area:exists}/{controller=Home}/{action=Index}/{id?}");

I can’t figure out what I did wrong. I didn’t have this problem before.
