NHibernate.MappingException: Unknown entity class

If you get MappingException error, there are two things you should check out: Make sure the name of the *.hbm.xml is spelled correctly — not *.hmb.xml nor *.mbh.xml Make sure the Build Action property is set to “Embeded Resource.” I learned this the hard way. First, I wrongly spelled hbm.xml and I had its Buld Action property set to “Content”. The above 2 points fixed the problem. Credit: VerySimple, Inc
