Error : DEP1630 : Invalid "TargetOsVersion" property

I was trying to get the Wikipedia sample app for windows store 8 from GitHub to run in visual studio 2015. The app is a HTML app.
When trying to run the app I was getting the following error
DEP1630 : Invalid “TargetOsVersion” property
The solution was to edit the WikipediaMetroTest.jsproj with notepad and change the Visual studio version to 14.0
