Async in Program.cs

Question

I have an asp.net core api and I am seeding data in my database, however I am using the usermanager from identity core which requires async.

I tried to async the void Main(string[] args) but that did not work.

  public static void Main(string[] args)
        {
            var host = CreateWebHostBuilder(args).Build();

            using (var scope = host.Services.CreateScope())
            {

               var dbContext = services.GetService<ApplicationDbContext>();

                var userManager = services.GetService<UserManager<Employee>>();
                DbSeeder.CreateDefaultCompany(dbContext, userManager);

            }

            host.Run();
        }

The only way I figured out how to get around this(though, from what I read it might not be best practice is)

// inside CreateDefaultCompany

 userManager.CreateAsync(employee1, "parts").GetAwaiter().GetResult();
