We have been using the Telerik.Web.UI and Telerik.Web.UI.Skins dlls for years. We just upgraded to 2016 Q1. The upgrade added references to a BUNCH of additional dlls - Telerik.Web.Spreadsheet, Telerik.Windows.Documents.Core, Telerik.Windows.Documents.Flow, Telerik.Windows.Documents.Spreadsheet, Telerik.Windows.Zip. None of which we use. Do we now have to ship those dlls? Or is there a way to remove those references and ship a lighter package?
