stcourth said In which future version of Uniface will support SQL Server 2016? Can we already use it with driver MSS 5 ?  

For Windows, the plan is Uniface 9.7.03/MG02 update in October.  It will be a new u5.1 driver.  The current u5.0 driver isn't supported and isn't tested so if you use it, obviously at your risk so make sure it's well tested with your app(s).  Linux will come later, I'm assuming 4 months later in the Uniface 9.7.04/MG03 release. At the moment there are not any libraries available for us to build with.  Uniface 10 might make it in the September release, but otherwise in the first maintenance pack. 

Oké, thanks for the information. Topic can be closed
