How to create the code behind of Razor page

When I create a new Razor page in Visual Studio 2017, the separated code behind file did not get created.

This is the screenshot of the problem highlighted.

We can see the Razor page called List.cshtml does not contain the code behind file. Contrast that with the default page about.cshtml, for example.

1 - Right click on "resturants", add class:

2 - in your case, call it List.cshtml.cs. This will create the code behind. It nows needs wiring up. Open the class that has been created.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
//Add the MVC usings
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;

//TODO The namespace will be correct in your code
namespace app_name.Pages.resturants
{
    //public class List
    //TODO correct the model name and inherit PageModel
    public List1Model : PageModel
    {
        public void OnGet()
        {
        }
    }
}

3 - In List.cshtml:

@page
@model app_name.Pages.resturants.List1Model
@{
}
