Connect Idoc to .Net wcf service

Not sure if this is the right venue, but we are trying to see if there is a way to setup SAP to send an Idoc to a .Net WCF Webservice without using a third party system (ie. PI or Biztalk). We have attempted it but we were not successful in setting it up so just looking to see if it can be done and if so, how to do it.

Thanks,

Chris
