  • Microsoft.EntityFrameworkCore.Relational
  • Microsoft.EntityFrameworkCore.Tools
  • Microsoft.AspNetCore.Identity.EntityFrameworkCore
Step 3
 
Now create a folder called ViewModel and “Add” a class with name RegisterViewModel. We will use this as a model for register.
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.ComponentModel.DataAnnotations;  
  4. using System.Linq;  
  5. using System.Threading.Tasks;  
  6.   
  7. namespace RegistrationFormCore.ViewModels  
  8. {  
  9.     public class RegisterViewModel  
  10.     {  
  11.         [Required]  
  12.         [EmailAddress]  
  13.         public string Email { get; set; }  
  14.   
  15.         [Required]  
  16.         [DataType(DataType.Password)]  
  17.         public string Password { get; set; }  
  18.   
  19.         [Required]  
  20.         [Display(Name ="Confirm Password")]  
  21.         [DataType(DataType.Password)]  
  22.         [Compare("Password",ErrorMessage ="Your password and confirm password do not match")]  
  23.         public string ConfirmPassword { get; set; }  
  24.   
  25.     }  
  26. }  
Step 4
 
Now under the project, create a folder with the name Controllers. After creating the “Controllers” folder, right-click on the “Controllers” folder and add a controller.

After clicking on "Add", another window will appear with DefaultController. Change the name to AccountController and click on "Add". The AccountController will be added under the Controllers folder. Don’t change the Controller suffix for all controllers, change only the highlight, and instead of Default, just change Account.

Step 5
 
Now “Add” IActionResultmethod with name Register. Write  the following below code to register user.
 
Controller class code
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Threading.Tasks;  
  5. using Microsoft.AspNetCore.Identity;  
  6. using Microsoft.AspNetCore.Mvc;  
  7. using RegistrationFormCore.ViewModels;  
  8.   
  9. namespace RegistrationFormCore.Controllers  
  10. {  
  11.     public class AccountController : Controller  
  12.     {  
  13.         private readonly UserManager<IdentityUser> userManager;  
  14.         private readonly SignInManager<IdentityUser> signInManager;  
  15.   
  16.         public AccountController(UserManager<IdentityUser>userManager,SignInManager<IdentityUser>signInManager)  
  17.         {  
  18.             this.userManager =userManager;  
  19.             this.signInManager = signInManager;  
  20.         }  
  21.   
  22.         public IActionResult Register()  
  23.         {  
  24.             return View();  
  25.         }  
  26.   
  27.         [HttpPost]  
  28.         public async Task<IActionResult> Register(RegisterViewModel model)  
  29.         {  
  30.             if (ModelState.IsValid)  
  31.             {  
  32.                 var user = new IdentityUser   
  33.                 {   
  34.                     UserName=model.Email,  
  35.                     Email=model.Email  
  36.                 };  
  37.                 var result = await userManager.CreateAsync(user, model.Password);  
  38.   
  39.                 if (result.Succeeded)  
  40.                 {  
  41.                     await signInManager.SignInAsync(user, isPersistent: false);  
  42.                     return RedirectToAction("Index", "Home");  
  43.                 }  
  44.                 foreach (var error in result.Errors)  
  45.                 {  
  46.                     ModelState.AddModelError("",error.Description);  
  47.                 }  
  48.             }  
  49.             return View();  
  50.         }  
  51.     }  
  52. }  
Step 6
 
Now right click on register action method and “Add View” with default name Register click on “Add”. It will be added under views folder; account folder with Register.cshtml.
  1. @model RegistrationFormCore.ViewModels.RegisterViewModel  
  2.   
  3. @{  
  4.     ViewData["Title"] = "Register";  
  5. }  
  6.   
  7. <div class="row">  
  8.     <div class="col-md-6 mx-auto">  
  9.         <div class="card">  
  10.             <div class="card-header bg-danger text-white">  
  11.                 <h5 class="text-uppercase text-center">Regirtation Form</h5>  
  12.             </div>  
  13.             <div class="card-body">  
  14.                 <form asp-action="Register">  
  15.                     <div asp-validation-summary="All" class="text-danger"></div>  
  16.                     <div class="form-group">  
  17.                         <label asp-for="Email"></label>  
  18.                         <input asp-for="Email" class="form-control" />  
  19.                         <span asp-validation-for="Email" class="text-danger"></span>  
  20.                     </div>  
  21.                     <div class="form-group">  
  22.                         <label asp-for="Password"></label>  
  23.                         <input asp-for="Password" class="form-control" />  
  24.                         <span asp-validation-for="Password" class="text-danger"></span>  
  25.                     </div>  
  26.                     <div class="form-group">  
  27.                         <label asp-for="ConfirmPassword"></label>  
  28.                         <input asp-for="ConfirmPassword" class="form-control" />  
  29.                         <span asp-validation-for="ConfirmPassword" class="text-danger"></span>  
  30.                     </div>  
  31.                     <input type="submit" value="Register" class="btn btn-sm btn-success text-uppercase rounded-0" />  
  32.                 </form>  
  33.             </div>  
  34.         </div>  
  35.     </div>  
  36. </div>  
Step 7
 
Now modify _Layout.cshtm and “Add” a link with Register.
  1. <!DOCTYPE html>  
  2. <html lang="en">  
  3. <head>  
  4.     <meta charset="utf-8" />

  41.     </div>  
  42.     <script src="~/lib/jquery/dist/jquery.min.js"></script>
