Running TaskScheduler from WebAPI - unable to schedule tasks

[santiago...@gmail.com]

Hello,

I am running a WebAPI controller that is trying to run a scheduled task.

This is a custom command that receives a simple parameter.

I use the following code inside the controller with [HttpPost] attribute: 

           using (var ts = new Microsoft.Win32.TaskScheduler.TaskService())

            {

                // Create a new task definition and assign properties

                var td = ts.NewTask();

                td.RegistrationInfo.Description = input.Description;

                // Create a trigger that will fire the task at this time every other day

                td.Triggers.Add(new Microsoft.Win32.TaskScheduler.DailyTrigger { DaysInterval = 2, StartBoundary = DateTime.Now.AddMinutes(1) });

                // Create an action that will launch Notepad whenever the trigger fires

                //td.Actions.Add(new Microsoft.Win32.TaskScheduler.ExecAction(qsClient, @"/key:" + retVal.ToString(), null));

                td.Actions.Add(new Microsoft.Win32.TaskScheduler.ExecAction("dir.exe","C:\\temp\\", null));

                // Register the task in the root folder

                //string taskName = input.OutputName.Replace("%DATE%", retVal.ToString());

                string taskName = "MyDirectory";

                ts.RootFolder.RegisterTaskDefinition(taskName, td);

            }

but when trying to execute this, I got the following error, I tried several other options but always end to this point:

    "ExceptionMessage": "(43,4):Task:",

    "ExceptionType": "System.Runtime.InteropServices.COMException",

    "StackTrace": "   at Microsoft.Win32.TaskScheduler.V2Interop.ITaskFolder.RegisterTaskDefinition(String Path, ITaskDefinition pDefinition, Int32 flags, Object UserId, Object password, TaskLogonType LogonType, Object sddl)

at Microsoft.Win32.TaskScheduler.TaskFolder.RegisterTaskDefinition(String path, TaskDefinition definition, TaskCreation createType, String userId, String password, TaskLogonType logonType, String sddl)

at Microsoft.Win32.TaskScheduler.TaskFolder.RegisterTaskDefinition(String path, TaskDefinition definition)

Are you guys familiar with this issue? My WebAPI service is running under IIS using an application pool with ApplicationPoolIdentity.

Thank you

I changed the Identity of the application pool from ApplicationPoolIdentity to LocalServices and it works.
