How to render at server side without @taghelper?

I am developing "ASP.NET Core Web API" with "Angular 4". I am following this tutorial of Microsoft.AspNetCore.SpaServices Server Side Prerendering and there are two important steps to use power `Microsoft.AspNetCore.SpaServices`:

1. go to your `Views/_ViewImports.cshtml` file, and add the following line:

`@addTagHelper "*, Microsoft.AspNetCore.SpaServices"`

2. Choose a place in one of your MVC views where you want to prerender a SPA component. For example, open `Views/Home/Index.cshtml`, and add markup like the following:

`<div id="my-spa" asp-prerender-module="ClientApp/boot-server"></div>`

But Web Api does not have `Views` folder and I cannot do above steps.

My question is can I use Microsoft.AspNetCore.SpaServices without@addTagHelper in `ASP.NET Core Web API`?
