Re: Problem with envelopes when upgrading from Biztalk 2002 to Biztalk 2006 R2

Which adapter are you using?  Are you sure it is the SOAP envelope and not the body of the message?  SOAP envelopes from BizTalk are valid XML, so it shouldn’t matter whether the enelope contains namespace prefixes such as “eps”.  There is no way to set BTS 2002 envelope mode, and modifying the evelope is not an easy task.  Your best bet is to use the WCF-BasicHttp adapter (http://msdn.microsoft.com/en-us/library/bb246019.aspx).  If simply using the adapter doesn’t fix the issue, you have some ability to mofidy the envelope by writing a WCF message inspector (http://weblogs.asp.net/paolopia/archive/2008/02/25/handling-custom-soap-headers-via-wcf-behaviors.aspx).  You would need to use the WCF-Custom adapter to hook in a message inspector via a custom behavior.
