Configuring WCF client gives the error "The message could not be processed. This is most likely because the action

Question

My web service returns a error message no matter what configurations I set. I get the following error message.

The message could not be processed. This is most likely because the action 'http://tempuri.org/ITestingWebService/DoWork' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.

Here are my server & client web.config sections for WCF.

Answer 1

You most likely have a service contract mismatch on the ITestingWebService interface. Try running a "Update Service Reference" by right clicking on the service reference in Visual Studio and see if that fixes the issue.
