我有MVC 5应用程序。
这是我根据需要编辑的默认ApplicationUser和ApplicationDbContext类
public class ApplicationUser : IdentityUser
{
[Key]
public Guid UserId { get; set; }
[Required]
public override string UserName { get; set; }
[Required, DataType(DataType.Password)]
public string Password { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public Boolean IsApproved { get; set; }
public string Company { get; set; }
[DataType(DataType.MultilineText)]
public string Comment { get; set; }
public DateTime DateTimeRegistered { get; set; }
public DateTime? LastLoginDate { get; set; }
public DateTime? LastActivityDate { get; set; }
public int PasswordFailureSinceLastSuccess { get; set; }
public DateTime? LastPasswordFailureDate { get; set; }
public string PasswordVerificationToken { get; set; }
public DateTime? PasswordVerificationTokenExpirationDate { get; set; }
public string ConfirmationToken { get; set; }
public List<AddressBook> AddressBook { get; set; }
public IEnumerable<Appointment> Appointments { get; set; }
public Role Role { get; set; }
public License License { get; set; }
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext():base("DefaultConnection")
{
}
protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<IdentityUser>().ToTable("Users");
modelBuilder.Entity<ApplicationUser>().ToTable("Users");
}
public DbSet<License> Licenses { get; set; }
public override IDbSet<IdentityRole> Roles { get; set; }
public DbSet<AddressBook> AddressBooks { get; set; }
public DbSet<AddressBookPerson> AddressBookPersons { get; set; }
public DbSet<Appointment> Appointments { get; set; }
public DbSet<Attendee> Attendees { get; set; }
public DbSet<Response> Responses { get; set; }
}
这是我的webconfig文件

这是默认的Accountcontroller类，没有任何改变
public class AccountController : Controller
{
public AccountController()
: this(new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext())))
{
}
public AccountController(UserManager<ApplicationUser> userManager)
{
UserManager = userManager;
}
public UserManager<ApplicationUser> UserManager { get; private set; }
// GET: /Account/Register
[AllowAnonymous]
public ActionResult Register()
{
return View();
}
//
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
var user = new ApplicationUser() { UserName = model.UserName };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
await SignInAsync(user, isPersistent: false);
return RedirectToAction("Index", "Home");
}
else
{
AddErrors(result);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
当我运行应用程序并尝试注册用户时，我在Post方法的这一部分出现错误
var result = await UserManager.CreateAsync(user, model.Password);

编辑1： 我评论了webconfig文件中的以下部分
<!--<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=DatePicker;Data Source=(local)" providerName="System.Data.SqlClient" />
</connectionStrings>-->
现在浏览器中的错误显示

错误与之前的行相同

答案 0 :(得分：0)
你是否像这样初始化你的Db
Database.SetInitializer(new TenantDbInitializer());
