: Property (Clase) (Microsoft.Office.Server.ApplicationRegistry.Administration)
Properties are typed values associated with metadata objects. Some properties control the behavior of the Business Data Catalog; others enhance features based on the Business Data Catalog such as Business Data Web Parts or business data in lists. Properties used by Microsoft Office SharePoint Server 2007 are documented under the relevant metadata object.

Ejemplo
The following code example shows how to create a method, complete with method instances, filter descriptors, default values, and type descriptors, for the ProductModel entity in the AdventureWorks2000 database.
Prerequisites
Ensure a Shared Service Provider is already created.
Create an LobSystem instance and set connection parameters as shown in Procedimiento para crear LobSystem mediante el modelo de objetos de administración.
Create the ProductModel entity as shown in Procedimiento para crear una entidad mediante el modelo de administración de objetos
Replace the constant value EnterYourSSPNameHere in the code with the name of your Shared Resource Provider.
