NHibernate InvalidProxyTypeException

Question

I get this NHhiberante when verifying my Fluent Mappings

FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

----> NHibernate.InvalidProxyTypeException : The following types may not be used as proxies: Domain.Address: method Equals should be 'public/protected virtual' or 'protected internal virtual' Domain.Person: method Equals should be 'public/protected virtual' or 'protected internal virtual' TearDown : System.NullReferenceException : Object reference not set to an instance of an object.

I Tried making my Equals method virtual however I just end up getting this error

System.ApplicationException : For property 'AddressPerson' expected 'Domain.Person' of type 'Domain.Person' but got 'PersonProxy5ce0cdda11ac4829a4f038c9f7944213' of type 'Domain.Person'

I am confused does anyone know what exactly is going on here?

Edit: It looks like you cant override : Equals(Person person) for IEquatable Not sure why this confuses NHibernate however?

As you mentioned in your edit, yes you can't implement IEqualityComparer<T> for an NHibernate entity class. Just override the simple public override bool Equals(object obj) and public override int GetHashCode().
