Error: Could not find a getter for property 'id_operacion' in class 'OperCapacMantenedoresApp.Operacion'

Hola!

He buscado en la documentación pero no he encontrado la solución. Creo que tengo todos los archivos bien definidos.
Operacion.hbm.xml y hibernate.cfg.xml tienen Build Action = "Embedded Resource".

¡Muchas gracias por sus sugerencias y comentarios!

NHibernate version: 1.2
Mapping documents:


<?xml version="1.0" encoding="utf-8" ?>

Change your mapping to be

Property names are case sensitive and you had a lowercase 'i'.

thanks!

No problem.
Another alternative is to specify access='field'

Good luck
