I got following error after that Workflow stopped working .
Workflow Instance ID: 03232 mscorlib The message with Action 'http://tempuri.org/SysWorkflowConfigurationService/getConfiguration' 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).

I tried following tricks but problem not get resolved.
1. Incremental CIL Compilation.
2. AOS Restart
3. Full CIL Compilation
