the "migrations.cs" not generated why?? please help

class generated properly, although lacks code creating appropriate tables because didn't adhere naming conventions record class.

data migration code generation requires follow several conventions in order work properly. i.e.:

• namespace of record must end .models or .records
• there has exist public property named id
• all properties have virtual (required nhibernate anyway)
• class cannot sealed
• class cannot abstract
• class has implement icontent or subclass of contentpartrecord

in case, namespace (should end .models) , incorrect casing of id (should id) culprits.
