What is the alternative for DisplayMemberPath="Value" for Windows Store applications?

Question

I think there is a bug with Windows Store Applications when it comes to using DisplayMemberPath="Value".
Here is my code
<ComboBox Height="40" VerticalAlignment="Stretch" SelectedValuePath="Key" DisplayMemberPath="Value" x:Name="comboBox1" FontSize="25"/>
var source = new Dictionary<string, double>();
source.Add("Item1", 0.4);
source.Add("Item2", 0.3);
source.Add("Item3", 0.1);
source.Add("Item4", 0.1);
var formateDSource = new Dictionary<string, string>();
foreach (var item in source)
formateDSource.Add(string.Format("[{0}, {1}]", item.Key, item.Value), item.Key);
comboBox1.ItemsSource = source;
If you use this code in WPF in works perfectly. However if you use this code in a Windows Store Application then the Combo Box is empty and an error is thrown. So is there an alternative way to do this in Windows Store Applications and have I unearthed a
bug? Because I have researched the Web for days and found no solution to this.*please do not comment unless you have tried my code as a Windows Store App not a WPF in Visual Studios. Can Someone post an example based on my code that works in Windows Store
Apps please because this is terrible.
Thanks

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined
objects and unknown namespaces.
