New Post: Can I use Microsoft.Win32.TaskScheduler.dll in web app(asp.net) for creating task scheduler

Hi
I would like to enquire about creating task scheduler with asp.net
Please kindly recommend me how to create task scheduler within web application with asp. net(C#).
I try testing by the following codes in console application. It is great.

using Microsoft.Win32.TaskScheduler;
static void Main(string[] args)
        {
            using (TaskService ts = new TaskService())
            {
                TaskDefinition td = ts.NewTask();
                td.RegistrationInfo.Description = "My first PurgeApplication task scheduler";

                DateTime start = DateTime.Now.AddMinutes(1);
                td.Triggers.Add(new TimeTrigger() { StartBoundary = start });

                string path = @"C:/inetpub/wwwroot/AppManageWindowScheduler/exe/PurgeApplication.exe";

                td.Actions.Add(new ExecAction(path, null, null));
                ts.RootFolder.RegisterTaskDefinition("My first parallell task scheduler", td);
            }
        }

However, I try testing in web app instead. It occur error.
http://localhost/AppManageWindowScheduler/Default.aspx

using Microsoft.Win32.TaskScheduler;
protected void Page_Load(object sender, EventArgs e)
    {
        CreateTaskRunOnce();
    }
    private void CreateTaskRunOnce()
    {
        using (TaskService ts = new TaskService())
        {
            TaskDefinition td = ts.NewTask();
            td.RegistrationInfo.Description = "My first PurgeApplication task scheduler";

            DateTime start = DateTime.Now.AddMinutes(1);
            td.Triggers.Add(new TimeTrigger() { StartBoundary = start });

           // string path = @"C:/inetpub/wwwroot/AppManageWindowScheduler/exe/PurgeApplication.exe";
            string path = Server.MapPath("~/exe/PurgeApplication.exe");

            td.Actions.Add(new ExecAction(path, null, null));
            ts.RootFolder.RegisterTaskDefinition("My first parallell task scheduler", td);
        }
    }

I suspect that error may occur from “string path = Server.MapPath("~/exe/PurgeApplication.exe");” .

Could you please suggest me to what is good solution for resolving this?
