WCF – The action is invalid or unrecognized error
October 15th, 2008 | Published in BizTalk Tips
When consuming a WCF Service in BizTalk, I came across the error: The action is invalid or unrecognized.
The reason was that when I created the logical Request/Response port for the service in the orchestration, I used a new port type.
When generating the files for consuming the service, BizTalk had automatically created a Port Type for the Request/Response port. When I used this port type, the error went away.
