I am getting this error after deploying my WCF code to prod server. The same is working fine in non-prod servers.

Error message : The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be modified while it is in the Opening state.

What could be the cause and how to fix this?

One of the solution, is to avoid using the Open method. When you call any WCF Service method Open call would be made internally. So It will be invoked automatically.
