Insert Data Into another table during Registration in ASP.NET MVC5 - asp.net

Question

I understand that ASP.NET MVC creates a default table "AspNetUser" for storing users information during registration. How do I get Some of those data such as "Username" and store it in a seperate table during the registration process.
Am trying to get the "username" supplied by the user which is by default stored in the "AspNetUser Table" and store it in the "Student Table" also during the registration process
Register action
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
StudentEntities db = new StudentEntities();
var student = new Student
{
Name = model.Username
};
db.Student.Add(Student);
db.SaveChanges();
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("Welcome", "Home");
}
else
{
AddErrors(result);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
This doesn't seem to work

If you are using MVC5, it means you are using identity2. So It is better to use that to get user details. The best approach is doing this:
Add the following using statement.
using Microsoft.AspNet.Identity;
You can now get more methods from the HttpContext.User.Identity.
var UserName = User.Identity.GetUserName();
var UserId = User.Identity.GetUserId();
Be noted that identity usually uses email as username. But you can change it anyway.
