How to create ApplicationUser by UserManager in Seed method of ASP .NET MVC 5 Web application

Question

I can create users in the old way:

 var users = new List<ApplicationUser> { 
                        new ApplicationUser{PasswordHash = hasher.HashPassword("TestPass44!"), Email = "[email protected]", UserName = "[email protected]",  SecurityStamp = Guid.NewGuid().ToString()},
                        new ApplicationUser{PasswordHash = hasher.HashPassword("TestPass44!"), Email = "[email protected]", UserName = "[email protected]",  SecurityStamp = Guid.NewGuid().ToString()}
                        };

users.ForEach(user => context.Users.AddOrUpdate(user));

context.SaveChanges();

but I want to do it the ASP.NET MVC 5.1 way using UserManager. I peeked how the Register POST method looks in AccountController:

 public async Task<ActionResult> Register(RegisterViewModel model) {
            if (ModelState.IsValid) {
                var user = new ApplicationUser() { UserName = model.Email, Email = model.Email };
                IdentityResult result = await UserManager.CreateAsync(user, model.Password);
                if (result.Succeeded) { [...]

so I tried do the same:

var user =  new ApplicationUser() { Email = "[email protected]", 
                                    UserName = "[email protected]"};
IdentityResult result =  UserManager.CreateAsync(user, "abcwq12312!P");

but I get this:

also If I just type UserManager. VS2013 does not shows any methods on the list.

So how to add user in this way?

EDIT1:

Answer 1

Ok so to create user CreateAsync is unnecessary the problem was somewhere else. One should use ApplicationUserManager not UserManager(this one did not add anything to the database).

 var store = new UserStore<ApplicationUser>(context);
 var manager =  new ApplicationUserManager(store);
 var user = new ApplicationUser() { Email = "[email protected]", UserName = "[email protected]" };
 manager.Create(user, "TestPass44!");
