Create a new ASP.NET Core MVC project in Visual Studio. Create a User model that represents the users in your application. This model will map to a database table. using System.ComponentModel.DataAnnotations; namespace YourNamespace.Models { public class User { public int Id { get; set; } [Required] [Display(Name = User Name)] public string Name { get; set; } [Required] [EmailAddress] public string Email { get; set; } [Required] [Display(Name = Phone Number)] public string PhoneNumber { get; set; } } } Install Entity Framework Core and create a UserContext class. Add the necessary NuGet packages a. Microsoft.EntityFrameworkCore.SqlServer b. Microsoft.EntityFrameworkCore.Tools In the Data folder create UserContext.cs to represent the database context using Microsoft.EntityFrameworkCore; using YourNamespace.Models; namespace YourNamespace.Data { public class UserContext : DbContext { public UserContext(DbContextOptions options) : base(options) { } public DbSet Users { get; set; } } } Configure the database connection in the appsettings.json file. ConnectionStrings: { DefaultConnection: Server=(localdb)\mssqllocaldb;Database=UserManagementDB;Trusted_Connection=True;MultipleActiveResultSets=true } Register the UserContext in the Program.cs file. builder.Services.AddDbContext (options => options.UseSqlServer(Configuration.GetConnectionString(DefaultConnection))); Run the migrations to create the database dotnet ef migrations add InitialCreate dotnet ef database update In the Controllers folder create UserController.cs with actions to add and display users. using Microsoft.AspNetCore.Mvc; using YourNamespace.Data; using YourNamespace.Models; using System.Linq; using System.Threading.Tasks; namespace YourNamespace.Controllers { public class UserController : Controller { private readonly UserContext _context; public UserController(UserContext context) { _context = context; } // Action to show all users public async Task Index() { var users = await _context.Users.ToListAsync(); return View(users); } // Action to display form to add a new user public IActionResult Create() { return View(); } // Action to save new user to the database [HttpPost] [ValidateAntiForgeryToken] public async Task Create(User user) { if (ModelState.IsValid) { _context.Add(user); await _context.SaveChangesAsync(); return RedirectToAction(nameof(Index)); } return View(user); } } } In the View/User folder create the views for displaying users (Index.cshtml) and adding a new user (Create.cshtml). Index.cshtml - Display Users in a Grid View This view displays the list of users in a simple table layout. @model IEnumerable @{ ViewData[Title] = User List; } User List Add New User ID Name Email Phone Number @foreach (var user in Model) { @user.Id @user.Name @user.Email @user.PhoneNumber } Create.cshtml - Form to Add a New User This view provides a form to add new users. @model YourNamespace.Models.User @{ ViewData[Title] = Add New User; } Add New User Save @section Scripts { @{await Html.RenderPartialAsync(_ValidationScriptsPartial);} } Run the application. Hope this will help.
