The ConnectWebParts(WebPart, ProviderConnectionPoint, WebPart, ConsumerConnectionPoint, WebPartTransformer) overload is used to connect controls when their connection points are incompatible. The incompatibility occurs when consumer implements a different interface than provider as its connection point. The transformer converts the data into a type that can be understood by consumer.
