I think the simplest solution is to just raise an event from the form once the task has completed.

void RunTask()
{
    Form form = new Form();
    form.TaskCompleted += new EventHandler(form_TaskCompleted);
    form.Show();
}

void form_TaskCompleted(object sender, EventArgs e)
{
    object result = ((Form)sender).GetResult();
}
