With Lync 2013, Microsoft has introduced a new VDI Plug-in for Windows devices. This Tech Preview release enables the Microsoft® Lync™ 2013 VDI Plug-in to be used with the Citrix Receiver for Windows 3.x and XenApp 6.x. The Tech Preview consists of a new plug-in to the Citrix Receiver for Windows called the Display Adapter Plug-in. This new plug-in supports the Remote Desktop Protocol Geometry Tracking Extension used by Lync 2013 and related Windows components to insert and correctly position child windows for rendering Lync video. With this architecture, all Lync media processing is done on the user’s Windows device, maximizing XenApp server scalability and ensuring optimal audio-video quality.
