A Business Object Framework for .NET/C#

Instead of attempting to reinvent yet another data access layer, this framework focuses on leveraging NHibernate 2.1 to provide useful ASP.NET focused functionality.

• Databinding, handling lazy properties
• Error handling
• Implementing common interfaces and events
• ICloneable, IEditableObject, IDataErrorInfo, INotifyPropertyChanged, INotifyPropertyChanging, NHibernate.Classic.IValidatable
• Providing additional events: OnDeleting, OnDeleted, OnSaving, OnSaved
• Validation
• Object state tracking
• Membership providers (Database agnostic)
• ICriteria Lambda Extensions
• Class & Mapping file code generation (to kick start projects from existing schemas)
• T4 Templates
