VS2017：为什么 razor 项目仍然指的是 MVC？

Question

I'm very confused about MVC and razor projects for ASP.NET Core 2.0. In Visual Studio 2017 I do the following:

• New project
• Web ASP.NET Core Application (C#)
• Web Application (NOT Web Application MVC)

But when I open the cs code of a page I see:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc.RazorPages;  // <------- MVC?

namespace WebApplication2.Pages
{
    public class AboutModel : PageModel
    {
        public string Message { get; set; }

        public void OnGet()
        {
            Message = "Your application description page.";
        }
    }
}

Why it still refers to MVC if I selected a razor only project?

My question rises from a deeper problem: I don't understand what documentation I have to follow! When I see a tutorial about razor or MVC I'm not sure if it applies to this type of project.

This is simply because the Microsoft.AspNetCore.Mvc namespace is where the microsoft team decided to put Razor. It doesn't mean that your project uses MVC, just that some classes it uses are located in a namespace that contains MVC in its name.

It is just a guess, but I believe it could simply be a historic thing. Razor used to really be just part of MVC, so it was under the MVC namespace but now that it doesn't need MVC to live they left it here for compatibility or consistency ? This question can probably only be answered by someone from microsoft :-/
