I am trying to get to grips with the new Membership system introduced in ASP.NET MVC 5 and I\'ve come across a small issue which I am pretty sure you will be able to help me
Mark the Person object as virtual in your ApplicationUser definition. That worked for me.
public class ApplicationUser : IdentityUser
{
public virtual Person Person { get; set; }
Explore IdentityManager.Store.UserManagement and IdentityManager.Store.Users.
ApplicationUser cUser = (ApplicationUser) await IdentityManager.Store.Users.FindByNameAsync(HttpContext.User.Identity.Name, new System.Threading.CancellationToken());
cUser.Surname = "New Something";
IdentityResult result1 = await IdentityManager.Store.SaveChangesAsync();
Above code is an example only. Basically you need to explore the Store property of IdentityManage.
When we used the Users object of our database context we ran into other tracking errors. In our application, we would retrieve users as such
var user = UserManager.FindById(userId);
Edit the properties:
user.StorageName = "gooblygook";
//whatever other properties you would like to use
And then we would save it with the UserManager in the controller:
UserManager.Update(user);
This is currently a working solution for us.
