    //relationship.
    CanBeReferencedRequest canBeReferencedRequest = new CanBeReferencedRequest
    {
        EntityName = referencedEntity
    };

    CanBeReferencedResponse canBeReferencedResponse =
        (CanBeReferencedResponse)_serviceProxy.Execute(canBeReferencedRequest);

    if (!canBeReferencedResponse.CanBeReferenced)
    {
        Console.WriteLine(
            "Entity {0} can't be the primary entity in this one-to-many relationship", 
            referencedEntity);

    {
        EntityName = referencingEntity
    };

    CanBeReferencingResponse canBeReferencingResponse =
        (CanBeReferencingResponse)_serviceProxy.Execute(canBereferencingRequest);

    if (!canBeReferencingResponse.CanBeReferencing)
