We are building WPF applications which will be deployed on Citrix. Currently you simply see a blue window under Citrix, although the app runs fine on the server itself.

There do seem to be some issues detailed on the net.

Microsoft hot fix

We've applied the hot fix but this does not appear to fix the problem for us at least.

Also, found this identical question on this site, but it had been removed by the author, so no answers.

I'm running citrix 4.5 on a Windows 2003 server. I am trying to publish a WPF app (any WPF app has this problem) and all I get is a blue rectangle where the app is supposed to be. The rectangle is the exact size and shape of the window I expect, but it is just blue (looks like the color of the citrix desktop background). Any ideas?
