The only thing I can tell you is this...
The exception occurred at Microsoft.Win32.TaskScheduler.V2Interop.IRegisteredTask.get_Xml()

I don't include the debugging symbols file for the task scheduler DLL with my program.

Crayjin: what are you putting in for the "createType" parameter? Make sure it is CreateOrUpdate or Create. If that is still not working, try running the process in an elevated account with "Run as Administrator". Sometimes there are permission problems that seem more prevalent the new the OS version.

```
var oneTimeTrigger = (RegistrationTrigger)taskDefinition.Triggers.Add(new RegistrationTrigger());

Comments: ** Comment from web user: petersunde **

Temporary workaround:

```
var oneTimeTrigger = (TimeTrigger)taskDefinition.Triggers.Add(new TimeTrigger());
oneTimeTrigger.StartBoundary = DateTime.Now.AddSeconds(5);
```

Comments: ** Comment from web user: dahall **

I don't believe this is a library or OS version problem. Instead, I would guess that you entered 'true' for the last parameter (forceV1) value in the TaskService constructor forcing the library to use the old (v1) code base from Microsoft. Under V1, the RegistrationTrigger is not supported.

Hi dahall,

thanks for your response.

In fact I'm using the TaskCreation.CreateOrUpdate enum value and the process is elevated. Let me give you some more information:

I'm using a RegistrationTrigger, with a delay of 8 seconds and a EndBoundary of 20 seconds.
  • RunLevel is TaskRunLevel.LUA
  • DeleteExpiredTaskAfter is 40 seconds
  • Principal.UserId is the UserName of the Win32_ComputerSystem ManagementObject (Example: WIN-GVLEGB4ESV6\Test )
If you need further information, I'm also available on other communication channels.

Will you post the code you are using to build the task and register it? I have a Win10 instance I can test it against. I'm not getting the failure building it out on my own.

var dialog = new TriggerEditDialog(trigger, supportV1Only: false);
dialog.ShowDialog();

Then interactive with the dialog:
1. Uncheck Expire
2. Change to "At log on"
3. Uncheck Activate
4. Change to "On a schedule".
