Rocky just came out with his CSLA .NET 2.0 Framework. For those of you unfamiliar with CSLA .NET:
“CSLA .NET enables the use of object-oriented design as the basis for creating powerful applications. Business objects based on the framework support many advanced features to simplify the creation of Windows Forms, Web Forms and Web Services interfaces.
The CSLA .NET framework is designed to allow great flexibility in object persistence, so business objects can use virtually any data sources available. The framework is designed to enable single tier and n-tier models through the concept of mobile objects. This provides the flexibility to optimize performance, scalability, security and fault tolerance with no changes to code in the UI or business objects.” - Rockford Lhotka
You can download CSLA .NET 2.0 from Rocky's site here.
Rocky's Expert C# 2005 Business Objects Book is supposed to be available here shortly as well. I hope it is just as good and even better than the previous version. You can read my review of Expert C# Business Objects for a little taste of the previous version.
