An XAF module is a ready-to-use package for a feature. A module introduces additional Controllers, Actions, List Editors, View Items, Application Model nodes, and properties.

An XAF module is a class library that contains a class derived from ModuleBase. This class allows XAF to recognize a library as a module. XAF-specific classes in a module are automatically collected by reflection and used for UI generation. Controllers declared in a module are created in every Frame of an XAF application. They allow you to implement custom code that runs when the Controller is activated.

XAF supports the following module types:

System Modules

XAF applications include system modules. These modules supply basic application functionality, such as a Navigation System, Printing, and Export, and cannot be disabled.

Built-in XAF Modules (listed below)

XAF includes a number of ready-to-use modules that are listed and described below. For information about how to register a built-in module in your application, refer to the following help topic: Register a Built-in XAF Module.

Custom XAF Modules

You can implement a custom module for your solution. Such a module can be reused in other XAF applications. For more information, refer to the following topic: Create and Register a Custom XAF Module.

Third-Party XAF Modules

XAF supports work with third-party modules, such as Llamachant Framework Modules, Reactive.XAF Modules, and other XAF Community Extensions. They are usually registered similar to custom XAF modules (Create and Register a Custom XAF Module). Refer to the module vendor documentation for more details.
