Creating Asp.net Identity user in Seed method of Db Initializer

Question

I have created my data layer with EF 6 code first and I am populating the db through Seed method of EvInitializer class inheriting from DropCreateDatabaseIfModelChanges. The implementation of Seed method is

protected override void Seed(EvContext context)
{
   //Add other entities using context methods
   ApplicationUserManager manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context));
   var user = new ApplicationUser { Email = "admin@myemail.com" ,UserName = "admin@myemail.com"};
   var result = await manager.CreateAsync(user, "Temp_123");//this line gives error. obviously await cannot be used in non- async method and I cannot make Seed async
}

My question is how I can add a user in Seed method using UserManager class. when I change var result = awit manager.CreateAsync(user, "Temp_123");
to
var result = manager.CreateAsync(user, "Temp_123").Result; //or .Wait
the application hangs indefinitely

In asp.net-identity-2 usermanager has non async methods to create.

var user = new ApplicationUser { Email = "admin@myemail.com", UserName = "admin@myemail.com" };
manager.Create(user, "Temp_123");

Same for rolemanager if you want to create "admin" role.

var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));
roleManager.Create(new Role("admin"));

make the user admin

manager.AddToRole(user.Id, "admin");

Edit: As trailmax commented, Create() extension method comes in with Microsoft.AspNet.Identity namespace so do not forget using Microsoft.AspNet.Identity
