New Post: Easy way to retrieve all tasks

Is there an easy way to retrieve all tasks (regardless of whether they are active or not)? I've seen the sample:

TaskService ts = new TaskService();
var allTasks = ts.FindAllTasks(x => x.IsActive);

But, that only returns active. I've tried to change the argument, but FindAllTasks requires an argument. As a work-around, I'm using:

TaskService ts2 = new TaskService();
var allTasks = ts2.FindAllTasks(x => x.Xml != "");

Is there a better way to do this?
