Unable to seed multiple roles in database

Hi all, 

I'm new to .net core and I trying to develop an web app (using angular template by default) with seeding database function. I successfully create other custom model records with entity framework while seeding the database but not IdentityRole model (which using roleStore)

This is my code using in seed function, given GetDefaultRoles() is return List<string> type, with data = System Admin, Moderator and Viewer

public class DbInitializer{ 
public static async Task Initialize(Context context)
{
 ...
RoleStore<IdentityRole> roleStore = new RoleStore<IdentityRole>(context);
            foreach (string roleName in GetDefaultRoles())
            {
                if (!context.Roles.Any(r => r.Name == roleName))
                {
                   await roleStore.CreateAsync(new IdentityRole() { Name = roleName, NormalizedName = roleName.ToUpper() });
                }
            }
   ...
}
}

Main function in Program.cs
using (var scope = host.Services.CreateScope())
            {
                var services = scope.ServiceProvider;
                try
                {
                    var context= services.GetRequiredService<Context>();
                    var result = DBInitializer.Initialize(context);
                }
                catch (Exception exception)
                {
                       //Write in Error log file
                }
            }

Every time I run the code to create new database, only the first record(System Admin) is inserted. Then I rebuild app and run again with the database is already created, second record (Moderator) is inserted and the third time then only insert the last record (viewer). 

Or some time in the first time run, the first 2 record is inserted but not the viewer record. I also increase the connection timeout, but not help. 

I debug the code and found after first time roleStore.CreateAsync is executed, the next loop will stop at if condition line and jump to Index() in HomeController. 

I also recheck the output of ASP.Net core web server, the below is the output for the first time build without database, it clearly stated the insert statement of Role record only execute one time.
