Retrieve All One-to-Many Relationships and Cascade Delete Behavior for a Dataverse Table Using C#

When performing a Dynamics 365 Field Service cleanup, it was necessary to delete numerous Work Order records. Understanding the impact on related records is crucial since not all relationships are configured for Cascade Delete; many use RemoveLink, which nullifies the relationship rather than deleting child records. This difference can lead to unintended update events on related tables, which affect integrations listening for changes. A console application was developed to retrieve and export relationship metadata for the msdyn_workorder table, helping identify tables affected by RemoveLink relationships and the ensuing updates. This utility is beneficial for reviewing cascade behaviors, understanding impacts on child tables, validating integration behaviors, and exporting metadata for documentation. The code is adaptable to other Dataverse tables by modifying the logical name, assisting in better managing data cleanup processes without triggering unnecessary system integrations.
