Shouldn't be any hocus pocus other than what it took to get the other .exe's running.  Anything that applies to .NET standards, like partial trust when running from a network share & so forth, but nothing other than what you've already run into.

I've made several very simple VB.NET exe files that sit on a Windows 2003 Server.  The network admin of our company merely added the DOTNETFX support library for .NET 2.0 and my VB.NET exe files ran like a charm across our Citrix Metaframe presentation server. 

How much additional admin hocus pocus is required to make a Strataframe Winforms application run across Citrix?
