We are currently using Actipro 2014.1 version in our product and are planning to upgrade to 2016.1 version. I downloaded 2016.1 Build 0633 version. While trying to compile with the dlls of this version we are getting compile errors since some of the controls that we are styling are missing. Can you please confirm if RaftingWindow class and ContainerSplitter class under ActiproSoftware.Windows.Controls.Docking.Primitives namespace has been removed? I could not find it in the documentation of the new version.
