In the following CodePlex message Can I develop XBAP application with this framework?   sjappie alerts me to the fact that the CompositeWPF XBAP application will not deploy and run in IIS - so far I've only used it in Visual Studio 2008 Debug mode; I confirmed that what he was saying was true.

I found this blog How to run WPF - XBAP as Full Trust Application to be very thorough on explaining how to configure an XBAP application so that it can run in a full-trust environment.  After complying with the steps the CompositeWPF Command demo will now run in IIS.
