Await and async in .NET 4.5 with C#
public Task<string> RunSlowOperationTask() { return Task.Factory.StartNew<string>(RunSlowOperation); }OR
var taskData = new CalcTaskData {ForDate = forDate.Value, param2 = Value2};
Task t = new Task(() => DoCalcAsync(taskData));
t.Start();
// Long running Task
private async Task DoCalcAsync(CalcTaskData calcTaskData)
{
// long operation
// simulate long wait (see note below)
// simulate long wait (see note below)
}
Note that Thread.Sleep was replaced by Task.Delay(2000).
Thread.Sleep blocks the thread whereas Task.Delay represents a work that will block the thread for two seconds
