read from get string?

Abhishek_Khatri 

Sorry this is just local on my laptop:

I have Survey.cshtml:

@page "/Survey"
@model SWAT2022.Views.Home.Index1Model
@{
    ViewData["Title"] = "Test";
}

<h1>Hello, world!</h1>
<h2>The time on the server is @DateTime.Now  LAT:@Model.Long  LONG:@Model.Lat </h2>

and the cs Survey.cshtml.cs:

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;

namespace SWAT2022.Views.Home
{
    public class Index1Model : PageModel
    {
        public string? Lat { get; set; }
        public string? Long { get; set; }
        public void OnGet()
        {
            Lat = Request.Query["Lat"]; ;
            Long = Request.Query["Long"]; ;
        }
    }
}

I must have a fundamental misunderstanding of RazorPages as I get this error now:

Any Idea how I can integrate this Razor into my project
