I am having the following error when configuring mvc3 and Nhibernate. Can anyone guide me what I have missed please.

the dialect was not set. Set the property hibernate.dialect. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: NHibernate.HibernateException: The dialect was not set. Set the property hibernate.dialect.

Source Error:
