Could not create the driver from NHibernate.Driver.OracleDataClientDriver error in NHibernate

I have been playing with Nhibernate to connect to an oracle database using ODP.NET. first POC project which was a console application worked properly but as soon as I moved the codes to a Web Application for POC I started getting “Could not create the driver from NHibernate.Driver.OracleDataClientDriver” error. scratching my head and think about the failure where the same exact code was running in the Console application, tried so many ways but no result. everything was in place, Oracle reference, Nhibernate reference and configuration etc…

finally I just thought of giving a shot to marking the Oracle.DataAccess database to be copied locally in the property window and surprisingly it started working. now don’t ask me why but if you face the same scenario just mark your set Copy Locally property of Oracle.DataAccess to true.
