Hi.
I have the following application structure:
- Asp.Net Mvc 2.0 web application running under medium trust.
- uNHAddIns (v3.0.0.892 built from trunk as of a couple of days ago)
for session nh management
- NH (v3.0.0.1001built from trunk)
- Windsor, ServiceLocator using WindsorAdaptor, Castle.DynamicProxy2,
Castle.Core all rebuilt with AllowPartiallyTrustedCallers attribute
I get an "Operation could destabilize the runtime" exception in
NHibernate.Cfg.MappingSchema.HbmClass (new for 3.0?) when a session
factory is created and nhibernate is configured. The exception is
thrown when the following property is accessed in HbmClass:
public IEnumerable<IEntityPropertyMapping> Properties
{
get { return Items != null ? Items.Cast<IEntityPropertyMapping>():
new IEntityPropertyMapping[0]; }
}
I've heard of similar problems when using Linq under medium trust. I
am guessing this is a bug (probably a microsoft one that we all have
to code around!) that only shows up under medium trust (works fine in
full trust but i'd like to run this app on a shared hosting
environment)
Here is the stack trace:

Any suggestions would be appreciated, i don't feel confident changing
the nh source code so I'm considering going back to previous versions
of nh and unhaddins to see if that helps.
Thanks
Rob
