Hi,

Is there any example nh works under asp.net <trust level="Medium">
permission.
(especially with burrow.)
It's necessery on the shared hosting environment.

BTW : I tried <reflection-optimizer use="false" /> settings and all
assemblies have AllowPartiallyTrustedCallers attribute.

Thanks.

Hibernate version :2.0.1

Maybe you need NHibernate ProxyGenerators:

Quote:

NHibernate ProxyGenerators (NHPG) is a simple utility that you can use to pre-generate lazy loading proxies for use with NHibernate. Why would you want to pre-generate lazy loading proxies you ask? The prime example is to make use of lazy loading functionality in a Medium Trust environment, like a shared hosting ASP.Net environment.

And? Have you succeeded already?
I am also doing my best but I still get the famous security exception with the following stacktrace.
Looks like NHibernate is still doing its reflection optimization calls?
