Using an adapter in Configurator's UD client method

Hello, I’ve been trying to save programmatically the part configurator when the user cancels the automatic drawing generation. I tried to reproduced the BO calls in the trace but It seems that some DataSets used for saving the configurator are accessible only from the adapter.

I created a configurator UD Client method but when I can’t instantiate the ConfiguratorRuntimeAdapter which is in Erp.Adapters according to dlls. The reference is missing.

Am I missing something?
