Version 3.0 is an additive update, meaning that you only need to use the .NET 3.0 features if you are using .NET 3.0. CSLA .NET 3.0 is useful for people using .NET 2.0!! These features include:

• Enhancements to the validation subsystem
  • Friendly names for properties
  • Better null handling in the RegExMatch rule method
  • New StringMinLength rule method
  • Help for code generation through the DecoratedRuleArgs class
• Data binding issues
  • Fixed numerous bugs in BusinessListBase to improve data binding behavior
  • Throw exception when edit levels get out of sync, making debugging easier
  • N-level undo changed to provide parity with Windows Forms data binding requirements
• AutoCloneOnUpdate
  • Automatically clone objects when Save() is called, but only when data portal is local
• Enhancements to the authorization subsystem
  • CanExecuteMethod() allows authorization for arbitrary methods

CSLA .NET 3.0 includes numerous bug fixes and some feature enhancements that benefit everyone. If you are using version 2.0 or 2.1, you should consider upgrading to 3.0 to gain these benefits, even if you aren't using .NET 3.0.

See the change logs for version 3.0, version 3.0.1 and version 3.0.2 for a more detailed list of changes.

Using CSLA .NET 3.0 is completely focused on how to use the new features in version 3.0. The book does not detail the internal changes to CSLA .NET itself, so all ~120 pages help you use the enhancements added since version 2.1.
