This sample shows a basic WCF Service using Basic HTTP Binding. This service is hosted inside IIS and uses a WCF Receive Location to process WCF messages inside BizTalk.
This code was built using a beta version of BizTalk 206 R2. The concepts are the same in the RTM release of BizTalk 2006 R2 but this code may not work.
