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.

Some of the specific areas of interest are:

• 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

Examples of usage

System.BusinessObjects.Framework

• See BasicUsage
• SampleConfig

System.BusinessObjects.Expressions

An older version of the code also exists (in the legacy branch) which is compatible with NHibernate 1.2.1GA.
