    CanBeReferencingRequest canBereferencingRequest = new CanBeReferencingRequest
    {
        EntityName = referencingEntity
    };

    CanBeReferencingResponse canBeReferencingResponse =

    {
        Console.WriteLine(
            "Entity {0} can't be the referencing entity in this one-to-many relationship", 
            referencingEntity);
