+													SQLite can store GUIDs in binary or text form, controlled by the BinaryGuid
+													connection string parameter (default is 'true'). The BinaryGuid setting will affect
+													how to cast GUID to string in SQL. NHibernate will attempt to detect this
+													setting automatically from the connection string, but if the connection
+													or connection string is being handled by the application instead of by NHibernate,
+													you can use the 'sqlite.binaryguid' NHibernate setting to override the behavior.
