Question

I had an old (but great) app using NHibernate 1.0.2. Worked like a charm.
But then I decided to upgrade to NHibernate 2.1.2. Had to change some stuff, worked great also.

Problem is, I founded out that new version works in some machines and do not work in others. What the heck?
Thinking a while, I discovered that it only works in pcs with SQL 2000 installed!! previous version used to works everywhere….
Check out a piece of my exception, it has to do with mssql2000Dialect

NHibernate.MappingException: Could not compile the mapping document: Datos.NH_VEN_ComprobanteBF.hbm.xml ---> NHibernate.HibernateException: Could not instantiate dialect class NHibernate.Dialect.MsSql2000Dialect ---> System.Reflection.TargetInvocationException: Se produjo una excepción en el destino de la invocación. ---> System.TypeInitializationException: Se produjo una excepción en el inicializador de tipo de 'NHibernate.NHibernateUtil'. ---> System.TypeLoadException: No se puede cargar el tipo 'System.DateTimeOffset' del ensamblado'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
