As stated in the issue tracker of the silverlight toolkit [1], ItemCountThreshold should not be set (and cannot be set using simple xaml).

However, there are two workarounds for this issue. If you you don't mind to use codebehind, set the property via SetValue:

//e.g., in the constructor, just after InitializeComponent();
ListPicker.SetValue(Microsoft.Phone.Controls.ListPicker.ItemCountThresholdProperty, 0);

To set the value in xaml, you can use a binding:

(...)

In this example, I use a bogus binding expression and set the value using FallbackValue. Of course, an actual working binding should work as well. The xaml approach was only tested on the WP8 SDK, however it should work on 7.1 as well.

Edit: Just found out that the xaml approach breaks the designer.
