Question

I realize what I\'m doing is probably pretty silly, but I\'m in the middle of learning WPF and would like to know how to do this.

I have a window with a listbox on i

You can also use the Action delegate with anonymous methods to update the main thread from the worker thread. For more information on the Action class you could look here :

If you would like to update the listbox from multiple points I suggest explicitally setting the delegate, however if you just wish to update the thread at a single point in a method with a single call it could be done as follows :

        listbox.Dispatcher.BeginInvoke(new Action(delegate()
        {
            listbox.Items.Add(item); //where item is the item to be added and listbox is the control being updated.
        }));

Note that I use the Action class as it takes encapsulates a method that has a single parameter (in this case a listItem).
