Is there an equivelent of the DesignMode property for Universal Apps?

In Winforms you can say (with some slightly unexpected behaviour) ``` if (DesignMode) { // Do something that only happens on Design mode } ``` In WPF, you've got ``` if (DesignerProperties.GetIsInDesignMode(this)) { // Do something that only happens on Design mode } ``` But I'm struggling to find a similar option for the slimmed down PCL world that is Universal apps?
