Visual Studio 2015 - Cannot find ListView.SeparatorColorProperty

Hey there ,
I'm new to C# and Xamarin, and there i got a Question regarding ListView:

I want to recolor my Divider / Separator of the Clicked Menu Element in a ListView.
I searched and found in the API the SeparatorColorProperty.
But when i try this:

myListView.setBinding(ListView.SeparatorColorProperty,Color.White);

Visual Studio tells me, there is no SeparatorColorProperty, so I'm quite confused.... Do I need to set it in an other way? Or am I missing an update?
