Dossies @ Work: Dynamics 365 CDS

I was doing the following: in my orchestration I was sending a message to a custom WCF service. The message was build dynamically (custom .NET class) and passed to a send port configured for a WCF service. All looked fine (and compiled correctly) until I ran the application: I received the "The adapter failed to transmit message going to send port" error. After some investigation it turned out I received the error because the type of the message I was sending through the send port did not match with the type the WCF expected at the other end. After updating my message with the correct namespace, all worked fine again.

I'm recently involved in an integration project concerning MS CRM 4.0 and BizTalk 2009. As a BizTalk newbie, I want to share some of the problems I encountered during development. Here's the first one: Microsoft.XLANGs.Core.UnexpectedMessageTypeException: Received unexpected message type '' does not match expected type If you have this BizTalk exception after you deploy your orchestration: Check the pipeline settings in your send port; check if it hasn't changed into PassThruTransmit/PassThruReceive instead of XmlTransmit/XmlReceive.
