Bug #78750 reminded me that ConfigurationManager uses internal
ClientConfigurationSystem which is based on Assembly.GetEntryAssembly().
The exception above happens when there is no entry assembly information,
which is also likely to happen around web services.

If you use xsp2 and still get this error, please file a bug on
bugzilla.
