At this point, I ve walked through many of the classes that make up CSLA .NET. Given that there are quite a few classes and types required to implement the framework, there s a need to organize them into a set of namespaces for easier discovery and use. Namespaces allow you to group classes together in meaningful ways so that you can program against them more easily. Additionally, namespaces allow different classes to have the same name as long as they re in different namespaces. From a business perspective, you might use a scheme such as the following: MyCompany.MyApplication.FunctionalArea.Class A convention like this immediately indicates that the class belongs to a specific functional area within an application and organization. It also means that the application could have multiple classes with the same names:

MyCompany.MyApplication.Sales.Product MyCompany.MyApplication.Manufacturing.Product It s quite likely that the concept of a product in sales is different from that in manufacturing, and this approach allows reuse of class names to make each part of the application as clear and selfdocumenting as possible. The same is true when you re building a framework. Classes should be grouped in meaningful ways so that they re comprehensible to the end developer. Additionally, use of the framework can be simplified for the end developer by putting little-used or obscure classes in separate namespaces. This way, the business developer doesn t typically see them via IntelliSense. Consider the UndoableBase class, which isn t intended for use by a business developer; it exists for use within the framework only. Ideally, when business developers are working with the framework, they won t see UndoableBase via IntelliSense unless they go looking for it by specifically navigating to a specialized namespace. The framework has some namespaces that are to be used by end developers and others that are intended for internal use. All the namespaces in CSLA .NET are prefixed with Csla. Table 2-8 lists the namespaces used in the CSLA .NET framework.

Namespace
Csla.Web.Design Csla.WebServiceHost Csla.Windows Csla.Workflow Csla.Wpf
Description
Contains the supporting types for the CslaDataSource control; not intended for use by business developers Contains the web services data portal host; not intended for use by business developers Contains controls to assist with Windows Forms data binding; used by Windows UI developers Contains types to assist with the use of Windows Workflow Foundation (WF); used by workflow developers Contains controls to assist with WPF data binding; used by WPF UI developers
The primary base classes intended for use by business developers go into the Csla namespace itself. They are named as follows: Csla.BusinessBase<T> Csla.BusinessListBase<T,C> Csla.ReadOnlyBase<T> Csla.ReadOnlyListBase<T,C> Csla.NameValueListBase<K,V> Csla.CommandBase The rest of the classes and types in the framework are organized into the remaining namespaces based on their purpose. You ll see how they all fit and are implemented in s 6 through 16. The end result is that a typical business developer can simply use the Csla namespace as follows: using Csla; All they ll see are the classes intended for use during business development. All the other classes and concepts within the framework are located in other namespaces and therefore won t appear in IntelliSense by default, unless the developer specifically imports those namespaces. When using custom authentication, you ll likely import the Csla.Security namespace. But if you re not using that feature, you can ignore those classes and they won t clutter up the development experience. Similarly, Csla.Data and Csla.Validation may be used in some cases, as you ll see in s 17 and 18. If the types they contain are useful, they can be brought into a class with a using statement; otherwise, they are safely out of the way.
