Using @addTagHelper in ASP.NET Core WebAPI. ASP.NET Prerendering

问题

I am developing "ASP.NET Core Web API" with "Angular 4". And this is my usual approach to use "Web API" template, so there are no folders such as Views.

It was not a problem till I wanted to use Microsoft.AspNetCore.SpaServices. 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?

So my questions are:

• How is it possible to use @addTagHelper in ASP.NET Core Web API?
• If it is not possible to use @addTagHelper in WebApi, is there any replacement for @addTagHelper in ASP.NET Web API?
• What should I do instead of using @addTagHelper?

回答1:

Tag Helpers render custom tags within Views, if you don't have a view there is no requirement for a tag helper or View to contain it. I you need to return html, you will probably need to return that via the API and create your own code to generate Html?
