How to make WPF app work as a child process in Citrix

Question

I am working on a 3rd party application that allows plugins to be written in .NET 1.1. I have decided I would like to write my plugin to call a seperate process from the .NET 1.1 plugin (achieved using Process.Start). This is fine- I create a new process that is a WPF app.

When I launch this through MSTSC everything works as expected, however when I run the app through Citrix XenApp, the WPF child app fails to render correctly, and the mouse position starts going crazy- the child process window is basically not usable. Is there a way to avoid this happening?

If I create a seperate WPF application and deploy this through Citrix everything works fine. If I create a child Windows forms app in .NET 3.5, that also works fine.

To fix this you need to apply the hot fix described in Microsoft KB 955692. Once that is applied this issue no longer occurs.
