How to register user phone number also in Token based authentication in ASP.Net MVC?

I want to save user phone number when the user registers a form.

My register form is working right now only with 3 fields(EmailID, password, confirm password) using the following code

//SignUp $('#btnSignUp').click(function () { console.log('Signup clicked'); var data = { "Email": $('#txtSingUpEmail').val(), "PhoneNumber": '546789651', //for testing I directly pass the value in JQuery "Password": $('#txtSignUpPassword').val(), "ConfirmPassword": $('#txtConfirmPassword').val() }; $.ajax({ type: 'POST', url: '/ProjectName/api/Account/Register', contentType: 'application/json; charset=utf-8', data: JSON.stringify(data) }).done(function (data) { console.log('Registered Succesfully'); $('#modalSignup').modal('hide'); $('#exampleModalPreview').modal('show'); }).fail(function (showError) { console.log('Signup failed'); console.log('full error = '+JSON.stringify(showError)); //$('#loginErrorMsg').text(JSON.parse(showError.responseText).error_description); }); }); 

AccountController

// POST api/Account/Register [AllowAnonymous] [System.Web.Mvc.ValidateAntiForgeryToken] [Route("Register")] public async Task<IHttpActionResult> Register(RegisterBindingModel model) { if (!ModelState.IsValid) { return BadRequest(ModelState); } //I add PhoneNumber parameter here var user = new ApplicationUser() { UserName = model.Email, Email = model.Email, PhoneNumber = model.PhoneNumber }; IdentityResult result = await UserManager.CreateAsync(user, model.Password); if (!result.Succeeded) { return GetErrorResult(result); } return Ok(); } 

I tried by adding PhoneNumber variable on below class, but it never saved with phone numbers

RegisterBindingModel class

public class RegisterBindingModel { [Required] [Display(Name = "Email")] public string Email { get; set; } [Required] [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [DataType(DataType.Password)] [Display(Name = "Confirm password")] [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")] public string ConfirmPassword { get; set; } //[Required] [Display(Name = "PhoneNumber")] public string PhoneNumber { get; set; } } 

UPDATE

I found the following method on metadata

UserManager

[AsyncStateMachine(typeof(UserManager<,>.<SetPhoneNumberAsync>d__d9))] [DebuggerStepThrough] public virtual Task<IdentityResult> SetPhoneNumberAsync(TKey userId, string phoneNumber); 

so when I execute this method on Register method like below code. It enters the phone number where the user is created

// POST api/Account/Register [AllowAnonymous] [System.Web.Mvc.ValidateAntiForgeryToken] [Route("Register")] public async Task<IHttpActionResult> Register(RegisterBindingModel model) { if (!ModelState.IsValid) { return BadRequest(ModelState); } //I add PhoneNumber parameter here var user = new ApplicationUser() { UserName = model.Email, Email = model.Email, PhoneNumber = model.PhoneNumber }; IdentityResult result = await UserManager.CreateAsync(user, model.Password); IdentityResult setPhoneNumber = await UserManager.SetPhoneNumberAsync("", model.PhoneNumber); if (!result.Succeeded) { return GetErrorResult(result); } return Ok(); } 

As well as it throws an error that cannot find key. I just take one userId(already registered userID's value) key from table. I pass it on the parameter like below, then it set's the phone number to both user(already registerd user and also newly register)
