How to fix this " Error There was an error running the selected code generator: 'startIndex cannot be larger than length of string. (Parameter 'startIndex')' "

Hi @NADA KETMEK,

After testing in my local, we can't reproduce the issue. So could you share your Model_Name.cs file with us.

This is my test mode class, it works for me.

using Microsoft.EntityFrameworkCore;
using System.ComponentModel.DataAnnotations;
namespace WebApplication2.Models
{
    public class TestModel
    {
        [Key]
        public int Id { get; set; }
        public Guid Guid { get; set; }
        public string? Name { get; set; }
    }
}

Best Regards

Hello I decided to send My File to my friends and Ask They to Create The New Scaffolded Item And they can Create the Scaffolded and No Error like Error There was an error running the selected code generator: 'startIndex cannot be larger than length of string. (Parameter 'startIndex')'

So I think Is it's because i use window 11 or not?

Hi @NADA KETMEK,

In my side, I am using windows 11 and it works fine. Could you uninstall and re-install vs2022 ? And try again.
