You can also use App Settings:

var applicationData = Windows.Storage.ApplicationData.current;
var localSettings = applicationData.localSettings;
var composite = new Windows.Storage.ApplicationDataCompositeValue();
composite["intVal"] = 1;
composite["strVal"] = "string";

localSettings.values["exampleCompositeSetting"] = composite;
