C# AspNetCore TagHelpers not resolving

I have a problem with TagHelpers, they are not being resolved.

I have added Microsoft.AspNetCore.Mvc.TagHelpers to the project using NuGet, and it is showing as installed.

I have the _ViewImports.cshtml file, containing...

@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

... in my Views/Shared folder.

The Index.cshtml view file has an entry in the head element...

<link rel="stylesheet" asp-href-include="lib/bootstrap/dist/css/*.min.css" />

The css files are in the referenced directory.

I have added...

 app.UseStaticFiles();

... to the Configure() startup function.

ConfigureServices() also includes...

 services.AddMvc();

When I run the app, and do a View Source on the received html, I can see the asp-href-include tag helper has not been resolved, it appears as it is in the cshtml file. There are no errors, and no exceptions occur.

I have tried restarting VS 2017, but no joy.

What have I missed that would stop tag helpers working but not generate errors? Also, how can I debug this?

I had my _ViewImports.cshtml file in the /Views/Shared folder (which looks sane, right?).

However, this file must go in the /Views folder. (Note, each view can have it's own copy in a local folder).

Effectively, the @addTagHelpers directive was being ignored, because the _ViewImports.cshtml file was in the wrong place and not being picked up.

Solution was to copy the file up one directory from /Views/Shared to /Views.
