Hi,

i have a project with NHibernate and an Microsoft Access DB. I use the NHibernate JetDriver.dll and it works fine. Now i want to switch to NHibernate 3.0, but just changining the assemblies is not working. I think the problem is, that the JetDriver.dll needs the old NHibernate 2.0 dll. I get an TypeLoadException that sais can not find NHibernate.dll Version 2.1.2.4.

Do i have to do other things than just changing the assemblies? Where can i get a new JetDriver dll? Or is this a total other problem?

By the way. I also use Fluent NHibernate. Maybe that could cause this problem too?

Ok. I downloaded the JetDriver Source code, replaced the old assemblies with the new ones and compiled everything. so i could solve the problem with the loadexception. Now i get a NotSupportedException while i build my sessionfactory. Does anybody know why???

You may want to use Reflector to track down your version and enter in assembly redirects. I am using nhibernate 3.0 with nhcontrib and recompiled for net 3.5 using nant -t:net-3.5. Some assembly redirects were still needed for a few things. But it runs fine and I have it starting up under spring.net.
