1.1.0.685 :: BuildConfiguration > DeepClone results in SecurityException when running under IIS

Sorry if this is a no-brainer !

I have been migrating my HBM environment to Fluent for the past while now and have just implemented the nHibernate configuration through FnH fluently Configure interface. All unit and integration tests have proved to be positive up until the point of me testing under IIS, where upon I receive an exception that leaves me stumped.

I have listed the complete stack trace at the end of this post.

My setup is Castle Windsor, and the NHibernateFacility which calls a custom FluentNHibernateConfigurationBuilder to fill in the missing configuration via the fluent configuration interface - which calls .BuildConfiguration().

This resulting configuration is then persisted to disk which isn't the issue here but I thought I would include the point just incase.

Can anyone assist or give me some guidance on where I should investigate further.

Thanks very much,
DC
