Step 2: Modify the generated service proxy

Even though the machine-generated Service Proxy code is not to be edited, let us slightly bend this rule by adding a few lines of code. These added lines instantiates a Timer object to measure the time it takes to bind to the server and invoke a method. This is illustrated in the sample code given in listing2.
