What happens if I have a proxied object that hasn't yet been fetched and call an internal method on it from another object?

It feels as if NHibernate should have no way of intercepting this, since the proxy is a subclass generated outside the assembly. Or how is it working?

Anyone? Would be nice to know if I should avoid to use internal methods.

I normally use "protected internal" and everything works fine...

On .NET 2.0 it is possible to grant access to your domain assembly from the dynamically-generated proxy assemblies using InternalsVisibleTo attribute. You'd have to look this up in the Castle.DynamicProxy documentation since I don't remember the exact details.

It seems as if there is no exception thrown when using internal without virtual with NHibernate. Can't this be a source to bugs?

Yes, it probably can. Added a JIRA issue to improve the validator, http://jira.nhibernate.org/browse/NH-988.

So, for proxying to work correctly with internals, I would need to add InternalVisibleTo("nameOfGeneratedAssembly") to my assembly?

Sorry, should have said that I didn't find much documentation at all. Checked http://wiki.castleproject.org/index.php ... umentation and looked through the items there (API didn't work for me). If anyone else finds anything please post here.

If it is the case that it is required to have InternalsVisibleTo it should probably be added to the documentation to NHibernate.

I'm bumping this since I haven't yet found an answer to whether or not InternalsVisibleTo must be used.

I posted a topic on the DynamicProxy forum a week ago, but I have got no answers yet.
