Tool to add INotifyPropertyChanged support to NHibernate's proxies, enabling their usage with WPF for example.

Two modes are available depending on whether your entity already implement INotifyPropertyChanged or not.

1. Reference NHibernate.PropertyChanged.dll
2. Configure your session factories with the proxy supplied in the library, PropertyChangedProxyFactoryFactory.

For example when using FluentNHibernate:

Fluently.Configure()
    .Database(SQLiteConfiguration.Standard.InMemory().ShowSql())
    .Mappings(m => m.AutoMappings.Add(AutoMap.AssemblyOf<Person>()))
    
    // just add this line
    .ProxyFactoryFactory<PropertyChangedProxyFactoryFactory>()
    
    .BuildSessionFactory();

1. Reference NHibernate.PropertyChanged.dll
2. Configure your session factories with the other proxy supplied in the library, AddPropertyChangedProxyFactoryFactory.

For example when using FluentNHibernate:

Fluently.Configure()
    .Database(SQLiteConfiguration.Standard.InMemory().ShowSql())
    .Mappings(m => m.AutoMappings.Add(AutoMap.AssemblyOf<Person>()))
    
    // just add these two lines
    .ProxyFactoryFactory<AddPropertyChangedProxyFactoryFactory>()
    .ExposeConfiguration(c => c.SetInterceptor(new AddPropertyChangedInterceptor()))
    
    .BuildSessionFactory();

Note that with this method, since the entities themselves don't implement INotifyPropertyChanged, when you create a new entity, no PropertyChanged event will be available. To get a new entity that implements it, you will need to use the following factory:

var person = AddPropertyChangedInterceptorProxyFactory.Create<Person>();

When you save these entities, you will need to specify the entity name:

Session.SaveOrUpdate(typeof(Person).FullName, person);

Because of these complications, it is recommended to use the first method. If you don't want to implement INotifyPropertyChanged by hand, you can use a tool like PropertyChanged.Fody.
