ASP.NET 核心标识扩展不保存

Question

我正在尝试扩展 ASP.NET 身份。我觉得我拥有大部分零件。模型和用户对象都会正确填充。但是，当我检查数据库中是否有通过 CreateAsync 函数插入的新记录时，新字段都是 NULL。我错过了什么？

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Register(RegisterViewModel model, string returnUrl = null)
{
ViewData["ReturnUrl"] = returnUrl;
if (ModelState.IsValid)
{
var user = new ApplicationUser { UserName = model.Email, Email = model.Email, FirstName = model.FirstName, LastName = model.LastName
, Organization = model.Organization };
var result = await _userManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
_logger.LogInformation("User created a new account with password.");
var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
var callbackUrl = Url.EmailConfirmationLink(user.Id.ToString(), code, Request.Scheme);
await _emailSender.SendEmailConfirmationAsync(model.Email, callbackUrl);
await _signInManager.SignInAsync(user, isPersistent: false);
_logger.LogInformation("User created a new account with password.");
return RedirectToLocal(returnUrl);
}
AddErrors(result);
}
// If we got this far, something failed, redisplay form
return View(model);
}

services.AddIdentity<ApplicationUser, IdentityRole>(options =>
{
// Signin settings
options.SignIn.RequireConfirmedEmail = false;
options.SignIn.RequireConfirmedPhoneNumber = false;
})
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();

public class ApplicationUser : IdentityUser
{
public String FirstName;
public String LastName;
public String Organization;
}

您需要在ApplicationUser类中使用自动实现的属性，而不仅仅是使用公共字段。这可能是问题所在。

public class ApplicationUser : IdentityUser
{
public String FirstName { get; set; }
public String LastName { get; set; }
public String Organization { get; set; }
}
