Reflection and dynamic invocation are fundamental to the NHibernate design, so I don't think anything can be done to change the code. On the other hand, I don't think this is a bug in NHibernate. I think the hosting providers are being unreasonable in their security settings. I think the "fix" is to pressure the hosting providers into permitting the use of this basic and conventional programming mechanism. I’m not sure what they plan to do.

I will ask them to allow using reflection without restrictions for my application, maybe i won't replace them on Webhost4life :).

This is what didn't show up before: add key="hibernate.bytecode.provider" value="null" I guess the less than and greater than characters are not friendly. This is what didn’t show up before:

add key=”hibernate.bytecode.provider” value=”null”

I quit my account at godaddy because nhibernate did not work and contacted webhost4life to make sure they support it before I sing up for the account. Their answer was that they do not support it on any shared hosting server. Now I'm a bit confused Are still using nhibernate on a shared hosting environment at webhost4life?

Are still using nhibernate on a shared hosting environment at webhost4life?

Thanks

Perhaps their new policy only applies to new accounts? I don't know. You might ask if they offer a trial period. You could try out your apps, but then take a refund if it doesn't work out.

They do have a "45 day money back guarantee" policy and I'll do as you suggest. I'm in the situation you were sometime ago: I want to put a project online and don't want to invest too much in hosting. Using NHibernate would also mean less work. Thank you once again, Joel hi Mike,

Second... Download the Castle.DynamicProxy-vs2005 project. NHibernate ships with the dll, but you will need to modify the assembly to allow lazy loading under medium trust. Once you have the assembly, make sure nhibernate references this assembly and not the old dll. Open the Castle.DynamicProxy-vs2005 project and look for the ModuleScope.cs file (it is right in the main directory). There look for the method: private AssemblyName GetAssemblyName (bool signStrongName) In there comment out the following code: if (signStrongName) { byte[] keyPairStream = GetKeyPair(); if (keyPairStream != null) { assemblyName.KeyPair = new StrongNameKeyPair(keyPairStream); } } Now give it a shot.
