Debugging a WCF service from a client application

Now that we have a fully working WCF service, let's have a look at the debugging options of this service. We will use our original client, HelloWorldClient, to discuss the debugging options; so, in the following sections, whenever you come across terms such as client, the client program, or the client application, refer to HelloWorldClient.

The first and the most common scenario is to start a client program in the debug mode and then step into our WCF service. Next, we will try this option to debug the service.

1. Start Visual Studio as an administrator and open the HelloWorld solution.

2. Change the client program's configuration file to call HelloWorldService hosted within IIS Express. Open the App.config file inside the HelloWorldClient project and set the address of the endpoint to http://localhost:55859/HostExpressServer/HelloWorldService...
