new bie question: publish Orchestration as WCF Service method to receive multiple parameters-Collection of common programming errors

A BizTalk multipart message is composed of one or more message parts. However, WCF has no concept of a multipart message. Because WCF does not use multipart messages, the BizTalk WCF adapters also do not use them. The problem is that you may have an existing BizTalk orchestration or pipeline that is written to produce or consume multipart messages.

If you need to get a multipart message into BizTalk Server by using an incoming WCF message and the WCF adapters, render your multipart data as XML in your WCF message. Develop a custom BizTalk pipeline component to process the incoming XML stream (WCF message) and create the appropriate BizTalk multipart message for your application. These steps can be done in reverse for the Send side if required.
