Yes it does!!
But let’s first understand that what is a proxy? As we already know whenever we have to use any web service or WCF service, we need to create proxy of that service and with the help of proxy, we use the functionalists provided by the web/WCF service. Proxy acts a intermediary between the client of the service and the actual service. Proxy provides a simple interface to the consumer of service and all the intricacies like creating a connection, creating and sending the request, getting the response etc is handled by the proxy itself.
