如何在Autofac注册中调用异步方法？

public class MyService : IMyService
{
    public async Task DoSomethingAsync()
    {
        // 异步操作的代码
    }
}

var builder = new ContainerBuilder();
builder.RegisterType<MyService>().As<IMyService>();
// 其他服务的注册

var container = builder.Build();

using (var scope = container.BeginLifetimeScope())
{
    var myService = scope.Resolve<IMyService>();
    await myService.DoSomethingAsync();
}
