Project Signing
The Csla.dll file is a signed assembly. This means that the assembly has a strong name and so can be identified uniquely. This is required because CSLA .NET optionally can use Enterprise Services, which requires that assemblies be signed. Additionally, there are many scenarios where applications desire strongly named assemblies so they can ensure that they are really interacting with the assembly they referenced at development time. Figure 6-3 shows the Signing tab in the project s properties window, where you can see that the CslaKey.snk file is being used to sign the assembly. The CslaKey.snk file is included as a file in the project and contains a public/private key pair. The public key is available to any code consuming the assembly and can be used to ensure that the private key (which should be kept private) was used to sign the DLL.

Figure 6-3. Visual Studio Signing tab Normally, when you sign your assemblies you would want to protect your key file to ensure that the private key remains private. The CslaKey.snk file included in the download is there for convenience so you can easily build the project. You may wish to replace this with your own key file if you want your application to only use the Csla.dll assembly you built.
Supporting Localization
The CSLA .NET framework supports localization. For a framework, the key to supporting localization is to avoid using any string literal values that might be displayed to the end user. The .NET Framework and Visual Studio 2008 offer features to assist in this area through the use of resources. To see the resource editor in Visual Studio, double-click the Properties node under the Csla project in Solution Explorer to bring up the project s properties window. Click the Resources tab to navigate to the built-in resource editor. Figure 6-4 shows this editor with several of the string resources from Resources.resx. The complete set of resources is available in the Resources.resx file in the download. Additionally, a number of people around the world have been kind enough to translate the resources to various languages. As this is an ongoing process, refer to www.lhotka.net/cslanet/download.aspx for updates to the framework and resource files.

Figure 6-4. Visual Studio resource editor Now that you understand the basic project structure, let s walk through each folder (and thus each namespace) in turn, so you have a high-level picture of the functionality contained in each one.
Csla Namespace
The Csla namespace contains the types that are most commonly used by business developers as they create business objects using CSLA .NET. The files in this namespace are in the top-level folder in the project: \. The primary classes in this namespace are the base classes used to support the stereotypes discussed in s 4 and 5. Figure 6-5 illustrates these classes. As you can see, these base classes implement a great many interfaces. Some of the interfaces are standard .NET interfaces, such as ICloneable, but most of them are defined in the Csla.Core namespace and are part of CSLA .NET. CSLA .NET is an inheritance-based framework, which means that the primary way developers use the framework is by inheriting from one of the framework s base classes. That is a powerful model because it allows a developer to tap into predefined functionality with very little effort. Much like inheriting from Form instantly gives you a fully functional window in Windows, inheriting from BusinessBase instantly gives you a fully functional business object that supports data binding, validation, authorization, and so forth. However, inheritance is not terribly flexible. A class can only inherit from one thing, while it can implement many interfaces. So for the normal scenarios, the base classes are ideal, but for advanced scenarios such as building a UI framework on top of CSLA business objects, these interfaces are invaluable. I discuss these more in the section on the Csla.Core namespace later in the chapter.
