When mapping with an XML file, there is no need to mark it as an embedded resource.  Simply load the XML mapping.

 

Saving and Loading XML Mappings

Dim db As IDataHelper = DataHelper.SessionFactory()　

db.Mapper.ObjectMap.Clear()

db.Mapper.MapTablesFromNamespace("Models")

db.Mapper.SaveObjectMap("mymap.xml")

db.Mapper.LoadObjectMap("mymap.xml")
