How to update ApplicationUser with new fields in asp.net webforms using local authentication?

I have added 3 new fields to my Register.aspx template (FirstName, LastName, BuisnessName). I have updated the database schema but when I register a new user, the user is created but the new fields are not added to the user record. I have extended the ApplicationUser class using IdentityUser. What have I done wrong or left out?

Any help would be greatly appreciated. Here is my code:

Register.aspx.cs

protected void CreateUser_Click(object sender, EventArgs e) { var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>(); var signInManager = Context.GetOwinContext().Get<ApplicationSignInManager>(); var user = new ApplicationUser() { UserName = Email.Text, Email = Email.Text, FirstName = FirstName.Text, LastName = LastName.Text, BusinessName = BusinessName.Text }; manager.Create(user, FirstName.Text); manager.Create(user, LastName.Text); manager.Create(user, BusinessName.Text); IdentityResult result = manager.Create(user, Password.Text); if (result.Succeeded) { // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771 string code = manager.GenerateEmailConfirmationToken(user.Id); string callbackUrl = IdentityHelper.GetUserConfirmationRedirectUrl(code, user.Id, Request); manager.SendEmail(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>."); if (user.EmailConfirmed) { signInManager.SignIn(user, isPersistent: false, rememberBrowser: false); IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response); } else { ErrorMessage.Text = "An email has been sent to your account. Please view the email and confirm your account to complete the registration process."; } } else { ErrorMessage.Text = result.Errors.FirstOrDefault(); } } 

Register.aspx

 <div class="form-horizontal"> <h4>Create a new account</h4> <hr /> <asp:ValidationSummary runat="server" CssClass="text-danger" /> <div class="form-group"> <asp:Label runat="server" AssociatedControlID="FirstName" CssClass="col-md-2 control-label">First Name</asp:Label> <div class="col-md-10"> <asp:TextBox runat="server" ID="FirstName" CssClass="form-control" /> <asp:RequiredFieldValidator runat="server" ControlToValidate="FirstName" CssClass="text-danger" ErrorMessage="The First Name field is required." /> </div> </div> <div class="form-group"> <asp:Label runat="server" AssociatedControlID="LastName" CssClass="col-md-2 control-label">Last Name</asp:Label> <div class="col-md-10"> <asp:TextBox runat="server" ID="LastName" CssClass="form-control" /> <asp:RequiredFieldValidator runat="server" ControlToValidate="LastName" CssClass="text-danger" ErrorMessage="The Last Name field is required." /> </div> </div> <div class="form-group"> <asp:Label runat="server" AssociatedControlID="BusinessName" CssClass="col-md-2 control-label">Business Name</asp:Label> <div class="col-md-10"> <asp:TextBox runat="server" ID="BusinessName" CssClass="form-control" /> <asp:RequiredFieldValidator runat="server" ControlToValidate="BusinessName" CssClass="text-danger" ErrorMessage="The Business Name field is required." /> </div> </div> <div class="form-group"> <asp:Label runat="server" AssociatedControlID="Email" CssClass="col-md-2 control-label">Email</asp:Label> <div class="col-md-10"> <asp:TextBox runat="server" ID="Email" CssClass="form-control" TextMode="Email" /> <asp:RequiredFieldValidator runat="server" ControlToValidate="Email" CssClass="text-danger" ErrorMessage="The email field is required." /> </div> </div> <div class="form-group"> <asp:Label runat="server" AssociatedControlID="Password" CssClass="col-md-2 control-label">Password</asp:Label> <div class="col-md-10"> <asp:TextBox runat="server" ID="Password" TextMode="Password" CssClass="form-control" /> <asp:RequiredFieldValidator runat="server" ControlToValidate="Password" CssClass="text-danger" ErrorMessage="The password field is required." /> </div> </div> <div class="form-group"> <asp:Label runat="server" AssociatedControlID="ConfirmPassword" CssClass="col-md-2 control-label">Confirm password</asp:Label> <div class="col-md-10"> <asp:TextBox runat="server" ID="ConfirmPassword" TextMode="Password" CssClass="form-control" /> <asp:RequiredFieldValidator runat="server" ControlToValidate="ConfirmPassword" CssClass="text-danger" Display="Dynamic" ErrorMessage="The confirm password field is required." /> <asp:CompareValidator runat="server" ControlToCompare="Password" ControlToValidate="ConfirmPassword" CssClass="text-danger" Display="Dynamic" ErrorMessage="The password and confirmation password do not match." /> </div> </div> <div class="form-group"> <div class="col-md-offset-2 col-md-10"> <asp:Button runat="server" OnClick="CreateUser_Click" Text="Register" CssClass="btn btn-default" /> </div> </div> </div> 

IdentityModels.cs

public class ApplicationUser : IdentityUser { public string FirstName { get; set; } public string LastName { get; set; } public string BusinessName { get; set; } public ClaimsIdentity GenerateUserIdentity(ApplicationUserManager manager) { // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType var userIdentity = manager.CreateIdentity(this, DefaultAuthenticationTypes.ApplicationCookie); // Add custom user claims here return userIdentity; } public Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager manager) { return Task.FromResult(GenerateUserIdentity(manager)); } } public class ApplicationDbContext : IdentityDbContext<ApplicationUser> { public ApplicationDbContext() : base("DefaultConnection", throwIfV1Schema: false) { } public static ApplicationDbContext Create() { return new ApplicationDbContext(); } }
