It is because you are calling await. So it will stop your execution and wait for the output.

my code is public ActionResult UploadOrderTypeXls(HttpPostedFileBase orderTypeFile)

var result = string.Empty;
if (orderTypeFile != null && orderTypeFile.ContentLength > 0)
{
string fileName = Common.SaveXLSFile(orderTypeFile, "OrderType");
if (!String.IsNullOrEmpty(fileName))
{
try
{
Task t = Task.Run(() =>
{
_BusinesObject._masterOrderType.RunEtlJobs("MasterOrderType");
});
TaskStatus ts = t.Status;
while (t.Status == TaskStatus.RanToCompletion)
{
return JavaScript("EnableUploadButton()");
}
}
