Hi, 

We're trying to upgrade an EPiServer 7 CMS instance to patch 1, but are running into some assembly binding problems.

I've installed the new NuGet packages for EPiServer.Core, EPiServer.CommonFramework, EPiServer.Framework and EPiServer.Mail, and followed the find/replace instructions here.

When I rebuild and start a clean Alloy test site I get some assembly loading problems from NHibernate and/or Castle, long stack trace below. I tried installing newer NHibernate and Castle via NuGet, but that just caused more problems as they are the wrong versions for the rest of the code.

We're at the start of a project, so could easily reinstall the whole EPiServer instance with a patched installer if that is the best approach. Thanks!
