MVC5 Identity Seed Users in database - asp.net-mvc-5

Question

I am getting an error that says: "UserId not found." when trying to seed multiple users into my database.
Here is my seed method:
protected override void Seed(newBestPlay.Models.ApplicationDbContext context)
{
// This method will be called after migrating to the latest version.
InitialCreate create = new InitialCreate();
create.Down();
create.Up();
context.Configuration.LazyLoadingEnabled = true;
if (!context.Roles.Any(r => r.Name == "Admin"))
{
var store = new RoleStore<IdentityRole>(context);
var manager = new RoleManager<IdentityRole>(store);
var role = new IdentityRole { Name = "Admin" };
manager.Create(role);
}
if (!context.Roles.Any(r => r.Name == "User"))
{
var store = new RoleStore<IdentityRole>(context);
var manager = new RoleManager<IdentityRole>(store);
var role = new IdentityRole { Name = "User" };
manager.Create(role);
}
if (!context.Users.Any(u => u.UserName == "user1"))
{
var store = new UserStore<ApplicationUser>(context);
var manager = new UserManager<ApplicationUser>(store);
var user = new ApplicationUser { UserName = "user1", Email = "email1" };
manager.Create(user, "ChangeItAsap!");
manager.AddToRole(user.Id, "Admin");
}
if (!context.Users.Any(u => u.UserName == "user2"))
{
var store = new UserStore<ApplicationUser>(context);
var manager = new UserManager<ApplicationUser>(store);
var user = new ApplicationUser { UserName = "user2", Email = "email2" };
manager.Create(user, "ChangeItAsap!");
manager.AddToRole(user.Id, "Admin");
}
}
It is failing on that last "manager.AddToRole" line. I figured out the second user isn't even getting added to the database, so it can't find a user.Id since it never got added.

Figured it out. It was not allowing dashes in my username. My username(email) has a dash in the domain part. I had to add in
this.UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false };
into my IdentityConfig.cs file into the ApplicationUserManager constructor so it now looks like this:
public class ApplicationUserManager : UserManager<ApplicationUser>
{
public ApplicationUserManager(IUserStore<ApplicationUser> store)
: base(store)
{
this.UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false };
}
.....

add this into your seed method:
var manager = new UserManager<ApplicationUser>(store);
manager.UserValidator = new UserValidator<ApplicationUser>(manager)
{
AllowOnlyAlphanumericUserNames = false,
};
