Async Inside Sync Actions

public ActionResult Sync1()
{
  using (var soapClient = MySoapClient())
  {
    var task = soapClient.Method1Async().ConfigureAwait(false);
    ViewBag.Result = task.GetAwaiter().GetResult();
  }
  return View();
}

// Or

public ActionResult Sync2()
{
  using (var soapClient = MySoapClient())
  {
    ViewBag.Result = CallMethod1Async().Result();
  }
  return View();
}

public async Task<bool> CallMethod1Async()
{
  using (var soapClient = MySoapClient())
  {
    return await soapClient.Method1Async().ConfigureAwait(false);
  }
}
