示例

This example shows how to execute a Finder method on the Product entity in the AdventureWorks2000 sample.

Prerequisites

• Ensure a Shared Service Provider is already created.

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

• Make sure the LobSystem object and entity names referenced in the example exist in the Business Data Catalog. Use valid names.
