asp-controller and asp-action attributes not working

After a little bit of digging I found that asp-controller and asp-action attributes are called anchor tag helpers, and are part of the

Microsoft.AspNetCore.Mvc.TagHelpers namespace

Apparently it is an alternative to using Razor. I was able to resolve the issue by creating ‘_ViewImports.cshtml’ and adding the below into the file:

@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

Once done that, anchor tag helpers were recognized and button start working as anticipated.
