  }

Program.cs

builder.Services.AddScoped<IUnitOfWork, UnitOfWork>();

using Microsoft.AspNetCore.Mvc;

using MyWebAp.Data;

using MyWebAp.Models;

namespace MyWebAp.Controllers

        }

        public IActionResult Index()

        {

            IEnumerable<Category> categories = _context.Categories;

            return View(categories);

        }

        [HttpGet]

        [HttpPost]

        [ValidateAntiForgeryToken]

        public IActionResult Create(Category category)

        {

            if (ModelState.IsValid)

                _context.SaveChanges();

                TempData["Sucess"] = "Category Created Sucessfully";

                return RedirectToAction("Index");

            }

            return View(category);

        }

        [HttpGet]

        public IActionResult Edit(int? id)

        {

            if (id == null || id == 0)

            {

                return NotFound();

            }

            var category = _context.Categories.Find(id);

            if (category == null)

                return RedirectToAction("Index");

            }

            return RedirectToAction("Index");

        }

        [HttpGet]

        public IActionResult Delete(int? id)

        {

            return RedirectToAction("Index");

            //return RedirectToAction("Index");

        }

    }

}

Right click on solution Create new Project select class library fie ( Project name- MyApp.Models)

create class library model file name- Catogry.cs (ya create kare ya drag n drop kre MyAppWeb k project model folder se model n error file ko drag n drop kre MyAppWeb project se phir namespace thik kare )

Catogry.cs  

using System.ComponentModel;

using System.ComponentModel.DataAnnotations;

namespace MyApp.Models

{

    public class Category

    {

        [Key]

        public int Id { get; set; }

        [Required]

        public string Name { get; set; }

        [DisplayName("Display Oder")]

        public int DisplayOder { get; set; }

        public DateTime CreatedDateTime { get; set; } = DateTime.Now;

    }

}

Create MyApp.DataAccessLayer project & drag n drop Data folder from MyAppWeb project & create Infrastructure folder for Repository (sub folder IRepository  n Repository )
