The challenge:

Create a WCF Service with Basic Authentication.
Consume the service with Adobe ActionScript® 3 (FLEX)

The outcome:

WCF code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service" in code, svc and config file together.
public class Service : IService
	public string GetData(int value)
		return string.Format("You entered: {0}", value);

	public CompositeType GetDataUsingDataContract(CompositeType composite)
		if (composite == null)
			throw new ArgumentNullException("composite");
		if (composite.BoolValue)
			composite.StringValue += "Suffix";
		return composite;
