Question
I've created a WCF service and when I browse to the endpoint I get the following fault:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<s:Fault>
<faultcode
xmlns:a="http://schemas.microsoft.com/ws/2005/05/addressing/none">
a:ActionNotSupported
</faultcode>
<faultstring xml:lang="en-GB">
The message with Action '' cannot be processed at the receiver,
due to a ContractFilter mismatch at the EndpointDispatcher.
This may be because of either a contract mismatch (mismatched
Actions between sender and receiver) or a binding/security
mismatch between the sender and the receiver. Check that sender
and receiver have the same contract and the same binding
(including security requirements, e.g. Message, Transport, None).
</faultstring>
</s:Fault>
</s:Body>
</s:Envelope>
I've fixed the problem but didn't enjoy the experience! Does anyone have any tips or tools for debugging problems like this?
Solution
I've found SvcTraceViewer.exe to be the most valuable tool when it comes to diagnosing WCF errors.
