Using the request headers directly

Another option is to just create and send the authentication header yourself.

1. Hook up to the DataServiceContext’s SendingRequest Event:

ctx.SendingRequest +=new EventHandler<SendingRequestEventArgs>(OnSendingRequest);

2. Add the Basic Authentication Header to the request:

static void OnSendingRequest(object sender, SendingRequestEventArgs e)  
{  
  var creds = “user” + “:” + “password”;  
  var bcreds = Encoding.ASCII.GetBytes(creds);  
  var base64Creds = Convert.ToBase64String(bcreds);   
  e.RequestHeader.Add(“Authorization”, “Basic ” + base64Creds);     
}

As you can see this is pretty simple. And has the advantage that it will work even if the server doesn’t respond with a challenge (i.e. WWW-Authenticate header).
