WCF: 'Specify username in ClientCredentials' error

Hi, I am completely new to WCF.  My goal is to use a service on one server to connect to multiple C# Windows application clients.  

I got the service running on my web server (a shared asp host, no SSL or dedicated IP), and the service display a web page telling me to create a class and code file using svcutil.exe.

I placed the class and code file in my C# app, and everything seems to be ok so far.

I call the class using a test button, and it instantiates with no error.

But when I call the "Hello world" function, I expect it to return a string, but instead I get the message:

"The username is not provided. Specify username in ClientCredentials."

So I added a password and username to my method which now looks like this:

        private void button2_Click(object sender, EventArgs e)
        {
            MyServiceClient client = new MyServiceClient();
            client.ClientCredentials.UserName.UserName = "xyz";
            client.ClientCredentials.UserName.Password = "123";

            // Use the 'client' variable to call operations on the service.
            textBox4.Text = client.MyOperation1("dave");

            // Always close the client.
            client.Close();
        }

Is this where I am supposed to enter the username and password on the client side?  And where do I set the username password on the server?  Or am I completely going in the wrong direction?


I know there are a lot of config permutations so I attached my web.config file.  

Also attached is the service.cs file from the web server.

Thank you.
