I figured this out, the release of NHibernate.dll that I had in my project did not had implemented the 'date' function in MsSql2000Dialect I looked through ILDASM.exe disassembler and saw that the 'date' was not implemented.
I donwloaded the source https://nhcontrib.svn.sourceforge.net/svnroot/nhibernate/trunk/nhibernate/src/ the latest in the trunk, and the 'date was implemented' you can see it here https://nhcontrib.svn.sourceforge.net/svnroot/nhibernate/trunk/nhibernate/src/NHibernate/Dialect/MsSql2000Dialect.cs compiled it through visual studio not through NANT and copied the dll's Nhibernate.dll, castle, linfu, etc.. and it worked perfectly, I wonder if the source that I compiled is ready to be used in a project or not? I got it from the trunk folder as you can see it above. The best way is to extend the class Nhibernate.Dialect.MsSql2000Dialect and add the 'date' function like this guy did, http://www.codewrecks.com/blog/index.php/2010/06/04/nhibernate-hql-query-with-only-date-part-of-a-datetimevalue/ but the problem is when I try to use my customized Dialect in hibernate.cfg.xml it throws an Exception InnerException: NHibernate.HibernateException Message=”Could not instantiate dialect class Entities.DbTools.Sql2008Dialect” Source=”NHibernate” StackTrace: at NHibernate.Dialect.Dialect.InstantiateDialect(String dialectName) at NHibernate.Dialect.Dialect.GetDialect(IDictionary`2 props) at NHibernate.Cfg.Configuration.AddValidatedDocument(NamedXmlDocument doc) InnerException: System.TypeLoadException Message=”Could not load type Entities.DbTools.Sql2008Dialect.
