Hi,

My existing hosting company has suddenly switched to a medium trust
setup.  I'm using the latest build from Castle and I've gone through a
number of issues with that.  (http://groups.google.com/group/castle-
project-users/browse_thread/thread/98937c21efa854de)

I've managed to progress things, with the help of the Castle team
however I'm now getting the following error and was wondering if
anyone here has managed to get the NHibernate side of things working
on medium trust.

I've set the ActiveRecord / NHibernate settings as described here
http://nhforge.org/wikis/howtonh/run-in-medium-trust.aspx

Has anyone got any further than this?

Here is the error I'm getting:

 Security Exception
Description: The application attempted to perform an operation not
allowed by the security policy.  To grant this application the
required permission please contact your system administrator or change
the application's trust level in the configuration file.
