Examples

The following code example shows you 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 object and set connection parameters as shown in How To: Create a LOBSystem Using the Administration Object Model.

• Create the ProductModel entity as shown in How To: Create an Entity Using the Administration Object Model

• Replace the constant value EnterYourSSPNameHere in the code with the name of your Shared Resource Provider.
