Distributing Applications and Components

Publish applications and components to and install them from AppExchange. When adding an application or component to a package, all definition bundles referenced by the application or component are automatically included, such as other components, events, and interfaces. Custom fields, custom objects, list views, page layouts, and Apex classes referenced by the application or component are also included. However, when you add a custom object to a package, the application and other definition bundles that reference that custom object must be explicitly added to the package. Other dependencies that must be explicitly added to a package include the following.

• CSP Trusted Sites
• Remote Site Settings

A managed package ensures that your application and other resources are fully upgradeable. To create and work with managed packages, you must use a Developer Edition organization and register a namespace prefix. A managed package includes your namespace prefix in the component names and prevents naming conflicts in an installer’s organization. After a managed package is released, the application or component names are locked, but the package developer can still edit these attributes.
