The Using CSLA .NET 3.0 Book now available for VB.NET and C#

by Robert Bazinet on Oct 19, 2007 |

The latest version of Rocky Lhotka's Component-based Scalable Logical Architecture for .NET (CSLA .NET) ebook, Using CSLA .NET 3.0, is available for C# and now VB.NET.  The framework enables developers to create an object-oriented business layer that abstracts and encapsulates the business logic and data.

CSLA .NET version 3.0 adds support for the latest Microsoft .NET 3.0 features, including:

  • Windows Presentation Foundation (WPF)
    • Creating WPF forms using business objects
    • Using the new controls in the Csla.Wpf namespace
      • CslaDataProvider
      • Validator
      • Authorizer
      • ObjectStatus
      • IdentityConverter
    • Maximizing XAML and minimizing C#/VB code
  • Windows Communication Foundation (WCF)
    • Using the new WCF data portal channel to seamlessly upgrade from Remoting, Web services or Enterprise Services
    • Building WCF services using business objects
    • Applying WCF security to encrypt data on the wire
    • Sending username/password credentials to a WCF service
      • Including use of the new Csla.Security.PrincipalCache class
    • Using the DataContract attribute instead of the Serializable attribute
  • Windows Workflow Foundation (WF)
    • Creating activities using business objects
    • Invoking a workflow from a business object
    • Using the WorkflowManager class in the Csla.Workflow namespace

This ~120 page ebook covers how to use these new capabilities, Version 3.0 is an additive update, meaning developers use the .NET 3.0 features if using .NET 3.0.

Improvements are not limited to .NET 3.0 features,  CSLA .NET has been improved for .NET 2.0 too.   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.

A wealth of information can be found at the CLSA .NET web site and the book can be order at the CSLA .NET store.
