This handy guide will provide you with hands-on experience with the configuration and operation of XenDesktop 7.1 and all the related components.

Citrix Infrastructure Visio Stencil Set
These are the latest set of 3D perspective stencils for your Citrix Delivery Center or Networking diagrams compatible with Microsoft Visio 2007/2010/2013.
The set contains icons for some of the more common components of any Citrix or Application deployment. This set replaces the old set and includes new Stencils for NetScaler SDX, XenMobile, various roles, and the Worx products.
Hopefully these will be of use to you, I have already put the Visio Stencil Set to use.
