Sample: Query connections by reciprocal roles (early bound)

 

Applies To: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online

This sample code is for Microsoft Dynamics 365 (online & on-premises). Download the Microsoft Dynamics CRM SDK package. The sample can be found in the following location in the download package:

SampleCode\CS\BusinessDataModel\BusinessManagement\QueryConnectionRolesByReciprocalRole.cs

Requirements

For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.

Demonstrates

This sample shows how to create matching roles and then find a matching role for a particular role.
