Notes for Callers

Examples

The following example shows how to use this message. For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. For the complete sample, see the link later in this topic. This sample creates an entity relationship between Account and Campaign entities by using CreateOneToManyRequest.
