Rockford Lhotka’s CSLA .NET framework is an application development framework that reduces the cost of building and maintaining applications.
The framework enables developers to leverage the power of object-oriented design as the basis for creating powerful applications. Business objects based on CSLA automatically gain many advanced features that simplify the creation of Windows Forms, Web Forms, WPF, WCF, WF and Web Services interfaces.
CSLA .NET allows great flexibility in object persistence, so business objects can use virtually any data sources available. The framework supports 1-, 2- 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.
