Add list of models to Asp.net Identity - asp.net

Question

I want to assign a list of stores to a particular client, based on the Identity Model in MVC 5. I want to be able to register a user/client using the default registration in the MVC 5 example code and be able to add a store, then assign the store to the user.
I'm having trouble being able to create a working viewmodel that incorporates the idenity model with a new list.
Here is what I have so far:
Model:
public class ApplicationUser : IdentityUser
{
//[Required]
[Display(Name = "Client/Company Name")]
public string ClientName { get; set; }
public List<Store> Stores { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
return userIdentity;
}
}
I tried to add to the existing default dbcontext:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public DbSet<Store> Stores { get; set; }
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
}
My controller blows up when I try to set my store clientname to the user clientname. Clientname or any other property is unavailable for ApplicationUser.
private ApplicationDbContext db = new ApplicationDbContext();
// GET: Stores
public ActionResult Index(ClientStoreViewModel viewModel)
{
var clients = from s in db.Stores
join c in db.Users
on s.ClientName equals u.ClientName
select new ClientStoreViewModel() { Stores = s, Users = u };
return View(clients);
}
Store class:
public class Store
{
public int Id { get; set; }
//public int ClientId { get; set; }
[Display(Name = "Client Name")]
public string ClientName { get; set; }
[Display(Name = "Store Name")]
public string Brand { get; set; }
[Display(Name = "Store Number")]
public string StoreNumber { get; set; }
[Display(Name="Store Login URL")]
public string LoginURL { get; set; }
}
Finally my viewmodel:
public class ClientStoreViewModel
{
public ApplicationUser Users { get; set; }
public Store Stores { get; set; }
public ClientStoreViewModel()
{
Stores = new Store();
Users = new ApplicationUser();
}
}
