DbContextClass

namespace WebApp.Models
{
    // You can add profile data for the user by adding more properties to your ApplicationUser class, please visit http://go.microsoft.com/fwlink/?LinkID=317594 to learn more.
    public class ApplicationUser : IdentityUser
    {
        public string FirstName { get; set; }

回答1:

Create a detail view of your class from the controller and let it scaffold and return user detail to your view. Import Microsoft.AspNet.Identity to identify the current user and use it in your linq statement E.g.

[Authorize()]
ActionResult Details()
{
  var UserId = User.Identity.GetUserId();
  var comp = db.AspNetUsers.Where(i => i.UserName== UserId).First();

  return View(comp);
}

Hope it helps
