Answer 1

From your connection string, it appears that you are connecting to a 2k5 server. If so, according to the NHibernate docs, the dialect should be set to NHibernate.Dialect.MsSql2005Dialect.
This is the sample configuration from the docs:
<session-factory>
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
<property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
<property name="connection.connection_string">Server=(local);Initial Catalog=dbname;User Id=user;Password=********</property>
</session-factory>
You could try if setting dialect to NHibernate.Dialect.MsSql2005Dialect works for you.

I have done a simple and stupid mistake. I have not included the right version of NHibernate.
Thanks #Marjin for replying.
