NHibernate with MS SQL Server 2005

[abdulofpk]

Hi!
I have MS SQL Server 2005 installed on my system. I am using NHibernate to interact with my database named 'BRUSDB'. I have set the following configuration for nhibernate:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section
name="nhibernate"
type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089"
/>
</configSections>

<nhibernate>
<add
key="hibernate.connection.provider"
value="NHibernate.Connection.DriverConnectionProvider"
/>
<add
key="hibernate.dialect"
value="NHibernate.Dialect.MsSql2005Dialect"
/>
<add
key="hibernate.connection.driver_class"
value="NHibernate.Driver.SqlClientDriver"
/>
<add
key="hibernate.connection.connection_string"
value="server=server; database=BRUSDB;user=sa;pwd=sorcim"
/>
</nhibernate>
</configuration>


when i run the program The type initializer for 'NHibernate.Cfg.Configuration' threw an exception:
'System.TypeInitializationException'
at line:
Configuration cfg = new Configuration();

If any one has know then kindly guid me.
Thanks.
