CSLA .NET is a software framework created by Rockford Lhotka that provides a standard way to create robust object oriented programs using business objects. Business objects are objects that abstract business entities in an object oriented program. Some examples of business entities include sales orders, employees, or invoices.
Although CSLA itself is free to download, the only documentation the creator provides are his books and videos, which are not free.
CSLA (Component-based Scalable Logical Architecture) was originally targeted toward Visual Basic 6 in the book Visual Basic 6.0 Business Objects by Lhotka. With the advent of Microsoft .NET, CSLA was completely rewritten from the ground up, with no code carried forward, and called CSLA .NET. This revision took advantage of Web Services and the object oriented languages that came with Microsoft .NET (in particular, Visual Basic.NET and C#).
CSLA .NET was expounded in Expert C# Business Objects and Expert One-on-One Visual Basic .NET Business Objects ISBN 1-59059-145-3, both written by Lhotka. Although CSLA and CSLA .NET were originally targeted toward Microsoft programming languages, most of the framework can be applied to most object oriented languages.
