Is there a max usage of Task.Delay?

Question

If I use Task.Delay for an extremely long time, for example a full day like so : 

await Task.Delay(TimeSpan.FromDays(1));

Is there issues with this? e.g. Will my application crash or something?

Answer 1

The short answer is no, Task.Delay can take up to int.MaxValue (in milliseconds), so delaying a day is OK.

However one thing to note is that depending on your application, it may be restarted in other ways. For example if this is a background task with ASP.NET Core, then you might redeploy your application meaning your Task.Delay gets reset (Or your process runs again and then starts the delay all over again).
