Windows Scheduler - switch Task status to Fail

Question

I'm currently developping a C# program that will be run every hour via the Windows Task Scheduler. I would like to know if there is a way for my program to return a specific value that will mark the task as failed if something went wrong.
I mean, do the Windows Task Scheduler expect certain type of return code when running a program?
Something Like:
0 <=> Everything is OK
Any other Value <=> ERROR

I found this but I think that it's more when you use the Task Scheduler API, and that allows you to get the task status.

Thank you for the Help!

Answer 1

I would just log the results to the Event Viewer. Then you can monitor it there with details.

Answer 2

You can return an int value in your main method, that value will be displayed in the "Last run Result" in the Task Scheduler.

static int Main() {
    return -1;
}

That will show 0xffffffff in the task scheduler

You can also use the System logs to provide more details about the error
