Hi 000rakesh,
Thank you for posting here.
According to your description, I note that your question is more related to NHibernate.
NHibernate is a third-party product for which we don't provide help, so I suggest you post your question in
NHibernate forum
for more help.
The CLR Forum discuss and ask questions about .NET Framework Base Classes (BCL) such as Collections, I/O, Regigistry, Globalization, Reflection. Also discuss all the other Microsoft libraries that are built on or extend the .NET Framework.
Thank you for your understanding.
Best Regards,
Xingyu Zhao
